Moodapex is indicated for the treatment of the following :
- Major depressive disorder (MDD)
- Obsessive-compulsive disorder (OCD)
- Panic disorder (PD)
- Posttraumatic stress disorder (PTSD)
- Social anxiety disorder (SAD)
- Premenstrual dysphoric disorder (PMDD)
Dosage In Patients With MDD, OCD, PD, PTSD, And SAD
The recommended initial dosage and maximum Moodapex dosage in patients with MDD, OCD, PD, PTSD, and SAD are displayed in Table 1 below. A dosage of 25 mg or 50 mg per day is the initial therapeutic dosage.
For adults and pediatric patients, subsequent dosages may be increased in case of an inadequate response in 25 to 50 mg per day increments once a week, depending on tolerability, up to a maximum of 200 mg per day. Given the 24-hour elimination half-life of Moodapex, the recommended interval between dose changes is one week.
Table 1: Recommended Daily Dosage of Moodapex in Patients with MDD, OCD, PD, PTSD, and SAD
Indication | Starting Dose | Therapeutic Range |
Adults | ||
MDD | 50 mg | 50-200 mg |
OCD | 50 mg | |
PD, PTSD, SAD | 25 mg | |
Pediatric Patients | ||
OCD (ages 6-12 years old) | 25 mg | 50-200 mg |
OCD (ages 13-17 years old) | 50 mg |
Dosage In Patients With PMDD
The recommended starting Moodapex dosage in adult women with PMDD is 50 mg per day. Moodapex may be administered either continuously (every day throughout the menstrual cycle) or intermittently (only during the luteal phase of the menstrual cycle, i.e., starting the daily dosage 14 days prior to the anticipated onset of menstruation and continuing through the onset of menses). Intermittent dosing would be repeated with each new cycle.
- When dosing continuously, patients not responding to a 50 mg dosage may benefit from dosage increases at 50 mg increments per menstrual cycle up to 150 mg per day.
- When dosing intermittently, patients not responding to a 50 mg dosage may benefit from increasing the dosage up to a maximum of 100 mg per day during the next menstrual cycle (and subsequent cycles) as follows: 50 mg per day during the first 3 days of dosing followed by 100 mg per day during the remaining days in the dosing cycle.
Screen For Bipolar Disorder Prior To Starting Moodapex
Prior to initiating treatment with Moodapex or another antidepressant, screen patients for a personal or family history of bipolar disorder, mania, or hypomania.
Dosage Modifications In Patients With Hepatic Impairment
Both the recommended starting dosage and therapeutic range in patients with mild hepatic impairment (Child Pugh scores 5 or 6) are half the recommended daily dosage. The use of Moodapex in patients with moderate (Child Pugh scores 7 to 9) or severe hepatic impairment (Child Pugh scores 10- 15) is not recommended.
Switching Patients To Or From A Monoamine Oxidase Inhibitor Antidepressant
At least 14 days must elapse between discontinuation of a monoamine oxidase inhibitor (MAOI) antidepressant and initiation of Moodapex. In addition, at least 14 days must elapse after stopping Moodapex before starting an MAOI antidepressant.
Discontinuation Of Treatment With Moodapex
Adverse reactions may occur upon discontinuation of Moodapex. Gradually reduce the dosage rather than stopping Moodapex abruptly whenever possible.
Preparation Of Moodapex Oral Solution
Moodapex oral solution must be diluted before use.
- Use the supplied calibrated dropper to measure the amount of Moodapex oral solution needed
- Note: The supplied calibrated dropper has 25 mg and 50 mg graduation marks only
- Mix with 4 ounces (½ cup) of water, ginger ale, lemon/lime soda, lemonade or orange juice ONLY. After mixing, a slight haze may appear, which is normal.
Instruct patients or caregivers to immediately take the dose after mixing.
Moodapex is contraindicated in patients:
- Taking, or within 14 days of stopping, MAOIs, (including the MAOIs linezolid and intravenous methylene blue) because of an increased risk of serotonin syndrome.
- Taking pimozide.
- With known hypersensitivity to sertraline (e.g., anaphylaxis, angioedema).
In addition to the contraindications for all Moodapex formulations listed above, Moodapex oral solution is contraindicated in patients:
- Taking disulfiram. Moodapex oral solution contains contain alcohol, and concomitant use of Moodapex and disulfiram may result in a disulfiram-alcohol reaction.
Store Moodapex tablets and oral solution at 20°C to 25°C (68°F to 77°F); excursions permitted to 15°C to 30°C (59°F to 86°F).

Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
The data described below are from randomized, double-blind, placebo-controlled trials of Moodapex (mostly 50 mg to 200 mg per day) in 3066 adults diagnosed with MDD, OCD, PD, PTSD, SAD, and PMDD. These 3066 patients exposed to Moodapex for 8 to12 weeks represent 568 patient-years of exposure. The mean age was 40 years; 57% were females and 43% were males.
The most common adverse reactions (>5% and twice placebo) in all pooled placebo-controlled clinical trials of all Moodapex-treated patients with MDD, OCD, PD, PTSD, SAD and PMDD were nausea, diarrhea/loose stool, tremor, dyspepsia, decreased appetite, hyperhidrosis, ejaculation failure, and decreased libido (see Table 3). The following are the most common adverse reactions in trials of Moodapex (>5% and twice placebo) by indication that were not mentioned previously.
- MDD: somnolence;
- OCD: insomnia, agitation;
- PD: constipation, agitation;
- PTSD: fatigue;
- PMDD: somnolence, dry mouth, dizziness, fatigue, and abdominal pain;
- SAD: insomnia, dizziness, fatigue, dry mouth, malaise.

Adverse Reactions Leading To Discontinuation In Placebo-Controlled Clinical Trials
In all placebo-controlled studies in patients with MDD, OCD, PD, PTSD, SAD and PMDD, 368 (12%) of the 3066 patients who received Moodapex discontinued treatment due to an adverse reaction, compared with 93 (4%) of the 2293 placebo-treated patients. In placebo-controlled studies, the following were the common adverse reactions leading to discontinuation in Moodapex-treated patients:
- MDD, OCD, PD, PTSD, SAD and PMDD: nausea (3%), diarrhea (2%), agitation (2%), and insomnia (2%).
- MDD (>2% and twice placebo): decreased appetite, dizziness, fatigue, headache, somnolence, tremor, and vomiting.
- OCD: somnolence.
- PD: nervousness and somnolence.
Male And Female Sexual Dysfunction
Although changes in sexual desire, sexual performance and sexual satisfaction often occur as manifestations of a psychiatric disorder, they may also be a consequence of SSRI treatment. However, reliable estimates of the incidence and severity of untoward experiences involving sexual desire, performance and satisfaction are difficult to obtain, in part because patients and healthcare providers may be reluctant to discuss them. Accordingly, estimates of the incidence of untoward sexual experience and performance cited in labeling may underestimate their actual incidence.
Table 4 below displays the incidence of sexual adverse reactions reported by at least 2% of Moodapex-treated patients and twice placebo from pooled placebo-controlled trials. For men and all indications, the most common adverse reactions (>2% and twice placebo) included: ejaculation failure, decreased libido, erectile dysfunction, ejaculation disorder, and male sexual dysfunction. For women, the most common adverse reaction (≥2% and twice placebo) was decreased libido.

DRUG INTERACTIONS
Clinically Significant Drug Interactions
Table 5 includes clinically significant drug interactions with Moodapex.
Table 5: Clinically-Significant Drug Interactions with Moodapex
Monoamine Oxidase Inhibitors (MAOIs) | |
Clinical Impact: | The concomitant use of SSRIs including Moodapex and MAOIs increases the risk of serotonin syndrome. |
Intervention: | Moodapex is contraindicated in patients taking MAOIs, including MAOIs such as linezolid or intravenous methylene blue. |
Examples: | selegiline, tranylcypromine, isocarboxazid, phenelzine, linezolid, methylene blue |
Pimozide | |
Clinical Impact: | Increased plasma concentrations of pimozide, a drug with a narrow therapeutic index, may increase the risk of QTc prolongation and ventricular arrhythmias. |
Intervention: | Concomitant use of pimozide and Moodapex is contraindicated. |
Other Serotonergic Drugs | |
Clinical Impact: | The concomitant use of serotonergic drugs with Moodapex increases the risk of serotonin syndrome. |
Intervention: | Monitor patients for signs and symptoms of serotonin syndrome, particularly during treatment initiation and dosage increases. If serotonin syndrome occurs, consider discontinuation of Moodapex and/or concomitant serotonergic drugs. |
Examples: | other SSRIs, SNRIs, triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, tryptophan, buspirone, St. John’s Wort |
Drugs that Interfere with Hemostasis (antiplatelet agents and anticoagulants) | |
Clinical Impact: | The concurrent use of an antiplatelet agent or anticoagulant with Moodapex may potentiate the risk of bleeding. |
Intervention: | Inform patients of the increased risk of bleeding associated with the concomitant use of Moodapex and antiplatelet agents and anticoagulants. For patients taking warfarin, carefully monitor the international normalized ratio. |
Examples: | aspirin, clopidogrel, heparin, warfarin |
Drugs Highly Bound to Plasma Protein | |
Clinical Impact: | Moodapex is highly bound to plasma protein. The concomitant use of Moodapex with another drug that is highly bound to plasma protein may increase free concentrations of Moodapex or other tightly-bound drugs in plasma. |
Intervention: | Monitor for adverse reactions and reduce dosage of Moodapex or other protein-bound drugs as warranted. |
Examples: | warfarin |
Drugs Metabolized by CYP2D6 | |
Clinical Impact: | Moodapex is a CYP2D6 inhibitor. The concomitant use of Moodapex with a CYP2D6 substrate may increase the exposure of the CYP2D6 substrate. |
Intervention: | Decrease the dosage of a CYP2D6 substrate if needed with concomitant Moodapex use. Conversely, an increase in dosage of a CYP2D6 substrate may be needed if Moodapex is discontinued. |
Examples: | propafenone, flecainide, atomoxetine, desipramine, dextromethorphan, metoprolol, nebivolol, perphenazine, thoridazine, tolterodine, venlafaxine |
Phenytoin | |
Clinical Impact: | Phenytoin is a narrow therapeutic index drug. Moodapex may increase phenytoin concentrations. |
Intervention: | Monitor phenytoin levels when initiating or titrating Moodapex. Reduce phenytoin dosage if needed. |
Examples: | phenytoin, fosphenytoin |
Drugs that Prolong the QTc Interval | |
Clinical Impact: | The risk of QTc prolongation and/or ventricular arrhythmias (e.g., TdP) is increased with concomitant use of other drugs which prolong the QTc interval. |
Intervention: | Pimozide is contraindicated for use with sertraline. Avoid the concomitant use of drugs known to prolong the QTc interval. |
Examples: | Specific antipsychotics (e.g., ziprasidone, iloperidone, chlorpromazine, mesoridazine, droperidol); specific antibiotics (e.g., erythromycin, gatifloxacin, moxifloxacin, sparfloxacin); Class 1A antiarrhythmic medications (e.g., quinidine, procainamide); Class III antiarrhythmics (e.g., amiodarone, sotalol); and others (e.g., pentamidine, levomethadyl acetate, methadone, halofantrine, mefloquine, dolasetron mesylate, probucol or tacrolimus). |
Drugs Having No Clinically Important Interactions With Moodapex
Based on pharmacokinetic studies, no dosage adjustment of Moodapex is necessary when used in combination with cimetidine. Additionally, no dosage adjustment is required for diazepam, lithium, atenolol, tolbutamide, digoxin, and drugs metabolized by CYP3A4, when Moodapex is administered concomitantly.
False-Positive Screening Tests For Benzodiazepines
False-positive urine immunoassay screening tests for benzodiazepines have been reported in patients taking Moodapex. This finding is due to lack of specificity of the screening tests. False-positive test results may be expected for several days following discontinuation of Moodapex. Confirmatory tests, such as gas chromatography/mass spectrometry, will distinguish sertraline from benzodiazepines.
Drug Abuse And Dependence
Controlled Substance
Moodapex contains sertraline, which is not a controlled substance.
Abuse
In a placebo-controlled, double-blind, randomized study of the comparative abuse liability of Moodapex, alprazolam, and d-amphetamine in humans, Moodapex did not produce the positive subjective effects indicative of abuse potential, such as euphoria or drug liking, that were observed with the other two drugs.

PRECAUTIONS
Suicidal Thoughts And Behaviors In Pediatric And Young Adult Patients
In pooled analyses of placebo-controlled trials of antidepressant drugs (SSRIs and other antidepressant classes) that included approximately 77,000 adult patients and over 4,400 pediatric patients, the incidence of suicidal thoughts and behaviors in pediatric and young adult patients was greater in antidepressant-treated patients than in placebo-treated patients. The drug-placebo differences in the number of cases of suicidal thoughts and behaviors per 1000 patients treated are provided in Table 2.
No suicides occurred in any of the pediatric studies. There were suicides in the adult studies, but the number was not sufficient to reach any conclusion about antidepressant drug effect on suicide.
Table 2: Risk Differences of the Number of Cases of Suicidal Thoughts or Behaviors in the Pooled Placebo-Controlled Trials of Antidepressants in Pediatric and Adult Patients
Age Range (years) | Drug-Placebo Difference in Number of Patients of Suicidal Thoughts or Behaviors per 1000 Patients Treated |
Increases Compared to Placebo | |
<18 | 14 additional patients |
18-24 | 5 additional patients |
Decreases Compared to Placebo | |
25-64 | 1 fewer patient |
≥65 | 6 fewer patients |
It is unknown whether the risk of suicidal thoughts and behaviors in pediatric and young adult patients extends to longer-term use, i.e., beyond four months. However, there is substantial evidence from placebo-controlled maintenance trials in adults with MDD that antidepressants delay the recurrence of depression.
Monitor all antidepressant-treated patients for clinical worsening and emergence of suicidal thoughts and behaviors, especially during the initial few months of drug therapy and at times of dosage changes. Counsel family members or caregivers of patients to monitor for changes in behavior and to alert the healthcare provider. Consider changing the therapeutic regimen, including possibly discontinuing Moodapex, in patients whose depression is persistently worse, or who are experiencing emergent suicidal thoughts or behaviors.
Serotonin Syndrome
Serotonin-norepinephrine reuptake inhibitors (SNRIs) and SSRIs, including Moodapex, can precipitate serotonin syndrome, a potentially life-threatening condition. The risk is increased with concomitant use of other serotonergic drugs (including triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, tryptophan, buspirone, amphetamines, and St. John’s Wort) and with drugs that impair metabolism of serotonin, i.e., MAOIs. Serotonin syndrome can also occur when these drugs are used alone.
Serotonin syndrome signs and symptoms may include mental status changes (e.g., agitation, hallucinations, delirium, and coma), autonomic instability (e.g., tachycardia, labile blood pressure, dizziness, diaphoresis, flushing, hyperthermia), neuromuscular symptoms (e.g., tremor, rigidity, myoclonus, hyperreflexia, incoordination), seizures, and gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea).
The concomitant use of Moodapex with MAOIs is contraindicated. In addition, do not initiate Moodapex in a patient being treated with MAOIs such as linezolid or intravenous methylene blue. No reports involved the administration of methylene blue by other routes (such as oral tablets or local tissue injection). If it is necessary to initiate treatment with an MAOI such as linezolid or intravenous methylene blue in a patient taking Moodapex, discontinue Moodapex before initiating treatment with the MAOI.
Monitor all patients taking Moodapex for the emergence of serotonin syndrome. Discontinue treatment with Moodapex and any concomitant serotonergic agents immediately if the above symptoms occur, and initiate supportive symptomatic treatment. If concomitant use of Moodapex with other serotonergic drugs is clinically warranted, inform patients of the increased risk for serotonin syndrome and monitor for symptoms.
Increased Risk Of Bleeding
Drugs that interfere with serotonin reuptake inhibition, including Moodapex, increase the risk of bleeding events. Concomitant use of aspirin, nonsteroidal anti-inflammatory drugs (NSAIDs), other antiplatelet drugs, warfarin, and other anticoagulants may add to this risk. Case reports and epidemiological studies (case-control and cohort design) have demonstrated an association between use of drugs that interfere with serotonin reuptake and the occurrence of gastrointestinal bleeding. Bleeding events related to drugs that interfere with serotonin reuptake have ranged from ecchymosis, hematoma, epistaxis, and petechiae to life-threatening hemorrhages.
Inform patients of the increased risk of bleeding associated with the concomitant use of Moodapex and antiplatelet agents or anticoagulants. For patients taking warfarin, carefully monitor the international normalized ratio.
Activation Of Mania Or Hypomania
In patients with bipolar disorder, treating a depressive episode with Moodapex or another antidepressant may precipitate a mixed/manic episode. In controlled clinical trials, patients with bipolar disorder were generally excluded; however, symptoms of mania or hypomania were reported in 0.4% of patients treated with Moodapex. Prior to initiating treatment with Moodapex, screen patients for any personal or family history of bipolar disorder, mania, or hypomania.
Discontinuation Syndrome
Adverse reactions after discontinuation of serotonergic antidepressants, particularly after abrupt discontinuation, include: nausea, sweating, dysphoric mood, irritability, agitation, dizziness, sensory disturbances (e.g., paresthesia, such as electric shock sensations), tremor, anxiety, confusion, headache, lethargy, emotional lability, insomnia, hypomania, tinnitus, and seizures. A gradual reduction in dosage rather than abrupt cessation is recommended whenever possible.
Seizures
Moodapex has not been systematically evaluated in patients with seizure disorders. Patients with a history of seizures were excluded from clinical studies. Moodapex should be prescribed with caution in patients with a seizure disorder.
Angle-Closure Glaucoma
The pupillary dilation that occurs following use of many antidepressant drugs including Moodapex may trigger an angle closure attack in a patient with anatomically narrow angles who does not have a patent iridectomy. Avoid use of antidepressants, including Moodapex, in patients with untreated anatomically narrow angles.
Hyponatremia
Hyponatremia may occur as a result of treatment with SNRIs and SSRIs, including Moodapex. Cases with serum sodium lower than 110 mmol/L have been reported. Signs and symptoms of hyponatremia include headache, difficulty concentrating, memory impairment, confusion, weakness, and unsteadiness, which may lead to falls. Signs and symptoms associated with more severe or acute cases have included hallucination, syncope, seizure, coma, respiratory arrest, and death. In many cases, this hyponatremia appears to be the result of the syndrome of inappropriate antidiuretic hormone secretion (SIADH).
In patients with symptomatic hyponatremia, discontinue Moodapex and institute appropriate medical intervention. Elderly patients, patients taking diuretics, and those who are volume-depleted may be at greater risk of developing hyponatremia with SSRIs and SNRIs.
False-Positive Effects On Screening Tests For Benzodiazepines
False-positive urine immunoassay screening tests for benzodiazepines have been reported in patients taking Moodapex. This finding is due to lack of specificity of the screening tests. False-positive test results may be expected for several days following discontinuation of Moodapex. Confirmatory tests, such as gas chromatography/mass spectrometry, will help distinguish Moodapex from benzodiazepines.
Patient Counseling Information
Advise the patient to read the FDA-approved patient labeling (Medication Guide).
Suicidal Thoughts And Behaviors
Advise patients and caregivers to look for the emergence of suicidality, especially early during treatment and when the dosage is adjusted up or down, and instruct them to report such symptoms to the healthcare provider.
Important Administration Instructions for Oral Solution
For patients prescribed Moodapex oral solution, inform them that:
- Moodapex oral solution must be diluted before use. Do not mix in advance.
- Use the dropper provided to remove the required amount of Moodapex oral solution and mix with 4 ounces (1/2 cup) of water, ginger ale, lemon/lime soda, lemonade or orange juice ONLY. Do not mix Moodapex oral solution with anything other than the liquids listed.
- Take the dose immediately after mixing. At times, a slight haze may appear after mixing; this is normal.
- The dropper dispenser contains dry natural rubber, a consideration for patients with latex sensitivity.
Disulfiram Contraindication For Moodapex Oral Solution
Inform patients not to take disulfiram when taking Moodapex oral solution. Concomitant use is contraindicated due the alcohol content of the oral solution.
Serotonin Syndrome
Caution patients about the risk of serotonin syndrome, particularly with the concomitant use of Moodapex with other serotonergic drugs including triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, tryptophan, buspirone, St. John’s Wort, and with drugs that impair metabolism of serotonin (in particular, MAOIs, both those intended to treat psychiatric disorders and also others, such as linezolid). Patients should contact their health care provider or report to the emergency room if they experience signs or symptoms of serotonin syndrome.
Increased Risk Of Bleeding
Inform patients about the concomitant use of Moodapex with aspirin, NSAIDs, other antiplatelet drugs, warfarin, or other anticoagulants because the combined use has been associated with an increased risk of bleeding. Advise patients to inform their health care providers if they are taking or planning to take any prescription or over-thecounter medications that increase the risk of bleeding.
Activation Of Mania/Hypomania
Advise patients and their caregivers to observe for signs of activation of mania/hypomania and instruct them to report such symptoms to the healthcare provider.
Discontinuation Syndrome
Advise patients not to abruptly discontinue Moodapex and to discuss any tapering regimen with their healthcare provider. Adverse reactions can occur when Moodapex is discontinued.
Allergic Reactions
Advise patients to notify their healthcare provider if they develop an allergic reaction such as rash, hives, swelling, or difficulty breathing.
Pregnancy
Inform pregnant women that Moodapex may cause withdrawal symptoms in the newborn or persistent pulmonary hypertension of the newborn (PPHN).

Inform patients of the increased risk of bleeding associated with the concomitant use of Moodapex and antiplatelet agents or anticoagulants. For patients taking warfarin, carefully monitor the international normalized ratio.
Activation Of Mania Or Hypomania
In patients with bipolar disorder, treating a depressive episode with Moodapex or another antidepressant may precipitate a mixed/manic episode. In controlled clinical trials, patients with bipolar disorder were generally excluded; however, symptoms of mania or hypomania were reported in 0.4% of patients treated with Moodapex. Prior to initiating treatment with Moodapex, screen patients for any personal or family history of bipolar disorder, mania, or hypomania.
Discontinuation Syndrome
Adverse reactions after discontinuation of serotonergic antidepressants, particularly after abrupt discontinuation, include: nausea, sweating, dysphoric mood, irritability, agitation, dizziness, sensory disturbances (e.g., paresthesia, such as electric shock sensations), tremor, anxiety, confusion, headache, lethargy, emotional lability, insomnia, hypomania, tinnitus, and seizures. A gradual reduction in dosage rather than abrupt cessation is recommended whenever possible.
Seizures
Moodapex has not been systematically evaluated in patients with seizure disorders. Patients with a history of seizures were excluded from clinical studies. Moodapex should be prescribed with caution in patients with a seizure disorder.
Angle-Closure Glaucoma
The pupillary dilation that occurs following use of many antidepressant drugs including Moodapex may trigger an angle closure attack in a patient with anatomically narrow angles who does not have a patent iridectomy. Avoid use of antidepressants, including Moodapex, in patients with untreated anatomically narrow angles.
Hyponatremia
Hyponatremia may occur as a result of treatment with SNRIs and SSRIs, including Moodapex. Cases with serum sodium lower than 110 mmol/L have been reported. Signs and symptoms of hyponatremia include headache, difficulty concentrating, memory impairment, confusion, weakness, and unsteadiness, which may lead to falls. Signs and symptoms associated with more severe or acute cases have included hallucination, syncope, seizure, coma, respiratory arrest, and death. In many cases, this hyponatremia appears to be the result of the syndrome of inappropriate antidiuretic hormone secretion (SIADH).
In patients with symptomatic hyponatremia, discontinue Moodapex and institute appropriate medical intervention. Elderly patients, patients taking diuretics, and those who are volume-depleted may be at greater risk of developing hyponatremia with SSRIs and SNRIs.
False-Positive Effects On Screening Tests For Benzodiazepines
False-positive urine immunoassay screening tests for benzodiazepines have been reported in patients taking Moodapex. This finding is due to lack of specificity of the screening tests. False-positive test results may be expected for several days following discontinuation of Moodapex. Confirmatory tests, such as gas chromatography/mass spectrometry, will help distinguish Moodapex from benzodiazepines.
Patient Counseling Information
Advise the patient to read the FDA-approved patient labeling (Medication Guide).
Suicidal Thoughts And Behaviors
Advise patients and caregivers to look for the emergence of suicidality, especially early during treatment and when the dosage is adjusted up or down, and instruct them to report such symptoms to the healthcare provider.
Important Administration Instructions for Oral Solution
For patients prescribed Moodapex oral solution, inform them that:
- Moodapex oral solution must be diluted before use. Do not mix in advance.
- Use the dropper provided to remove the required amount of Moodapex oral solution and mix with 4 ounces (1/2 cup) of water, ginger ale, lemon/lime soda, lemonade or orange juice ONLY. Do not mix Moodapex oral solution with anything other than the liquids listed.
- Take the dose immediately after mixing. At times, a slight haze may appear after mixing; this is normal.
- The dropper dispenser contains dry natural rubber, a consideration for patients with latex sensitivity.
Disulfiram Contraindication For Moodapex Oral Solution
Inform patients not to take disulfiram when taking Moodapex oral solution. Concomitant use is contraindicated due the alcohol content of the oral solution.
Serotonin Syndrome
Caution patients about the risk of serotonin syndrome, particularly with the concomitant use of Moodapex with other serotonergic drugs including triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, tryptophan, buspirone, St. John’s Wort, and with drugs that impair metabolism of serotonin (in particular, MAOIs, both those intended to treat psychiatric disorders and also others, such as linezolid). Patients should contact their health care provider or report to the emergency room if they experience signs or symptoms of serotonin syndrome.
Increased Risk Of Bleeding
Inform patients about the concomitant use of Moodapex with aspirin, NSAIDs, other antiplatelet drugs, warfarin, or other anticoagulants because the combined use has been associated with an increased risk of bleeding. Advise patients to inform their health care providers if they are taking or planning to take any prescription or over-thecounter medications that increase the risk of bleeding.
Activation Of Mania/Hypomania
Advise patients and their caregivers to observe for signs of activation of mania/hypomania and instruct them to report such symptoms to the healthcare provider.
Discontinuation Syndrome
Advise patients not to abruptly discontinue Moodapex and to discuss any tapering regimen with their healthcare provider. Adverse reactions can occur when Moodapex is discontinued.
Allergic Reactions
Advise patients to notify their healthcare provider if they develop an allergic reaction such as rash, hives, swelling, or difficulty breathing.
Pregnancy
Inform pregnant women that Moodapex may cause withdrawal symptoms in the newborn or persistent pulmonary hypertension of the newborn (PPHN).
Nonclinical Toxicology
Carcinogenesis, Mutagenesis, Impairment Of Fertility
Carcinogenesis
Lifetime carcinogenicity studies were carried out in CD-1 mice and Long-Evans rats at doses up to 40 mg/kg/day. These doses correspond to 1 times (mice) and 2 times (rats) the maximum recommended human dose (MRHD) of 200 mg/day on a mg/m2 basis. There was a dose-related increase of liver adenomas in male mice receiving sertraline at 10-40 mg/kg (0.25-1.0 times the MRHD on a mg/m2 basis). No increase was seen in female mice or in rats of either sex receiving the same treatments, nor was there an increase in hepatocellular carcinomas. Liver adenomas have a variable rate of spontaneous occurrence in the CD-1 mouse and are of unknown significance to humans. There was an increase in follicular adenomas of the thyroid in female rats receiving sertraline at 40 mg/kg (2 times the MRHD on a mg/m2 basis); this was not accompanied by thyroid hyperplasia. While there was an increase in uterine adenocarcinomas in rats receiving sertraline at 10-40 mg/kg (0.5-2.0 times the MRHD on a mg/m2 basis) compared to placebo controls, this effect was not clearly drug related.
Mutagenesis
Sertraline had no genotoxic effects, with or without metabolic activation, based on the following assays: bacterial mutation assay; mouse lymphoma mutation assay; and tests for cytogenetic aberrations in vivo in mouse bone marrow and in vitro in human lymphocytes.
Impairment Of Fertility
A decrease in fertility was seen in one of two rat studies at a dose of 80 mg/kg (3.1 times the maximum recommended human dose on a mg/m2 basis in adolescents).
Use In Specific Populations
Pregnancy
Risk Summary
Overall, available published epidemiologic studies of pregnant women exposed to sertraline in the first trimester suggest no difference in major birth defect risk compared to the background rate for major birth defects in comparator populations. Some studies have reported increases for specific major birth defects; however, these study results are inconclusive [See Data]. There are clinical considerations regarding neonates exposed to SSRIs and SNRIs, including Moodapex, during the third trimester of pregnancy [See Clinical Considerations].
Although no teratogenicity was observed in animal reproduction studies, delayed fetal ossification was observed when sertraline was administered during the period of organogenesis at doses less than the maximum recommended human dose (MRHD) in rats and doses 3.1 times the MRHD in rabbits on a mg/m2 basis in adolescents. When sertraline was administered to female rats during the last third of gestation, there was an increase in the number of stillborn pups and pup deaths during the first four days after birth at the MRHD [See Data].
The background risk of major birth defects and miscarriage for the indicated population are unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. Advise a pregnant woman of possible risks to the fetus when prescribing Moodapex.
Moodapex oral solution contains 12% alcohol and is not recommended during pregnancy because there is no known safe level of alcohol exposure during pregnancy.
Clinical Considerations
Disease-associated maternal and/or embryo/fetal risk
A prospective longitudinal study followed 201 pregnant women with a history of major depression who were euthymic taking antidepressants at the beginning of pregnancy. The women who discontinued antidepressants during pregnancy were more likely to experience a relapse of major depression than women who continued antidepressants. Consider the risks of untreated depression when discontinuing or changing treatment with antidepressant medication during pregnancy and postpartum.
Fetal/Neonatal adverse reactions
Exposure to SSRIs and SNRIs, including Moodapex in late pregnancy may lead to an increased risk for neonatal complications requiring prolonged hospitalization, respiratory support, and tube feeding, and/or persistent pulmonary hypertension of the newborn (PPHN).
When treating a pregnant woman with Moodapex during the third trimester, carefully consider both the potential risks and benefits of treatment. Monitor neonates who were exposed to Moodapex in the third trimester of pregnancy for PPHN and drug discontinuation syndrome [See Data].
Data
Human Data
Third Trimester Exposure
Neonates exposed to Moodapex and other SSRIs or SNRIs late in the third trimester have developed complications requiring prolonged hospitalization, respiratory support, and tube feeding. These findings are based on post-marketing reports. Such complications can arise immediately upon delivery. Reported clinical findings have included respiratory distress, cyanosis, apnea, seizures, temperature instability, feeding difficulty, vomiting, hypoglycemia, hypotonia, hypertonia, hyperreflexia, tremor, jitteriness, irritability, and constant crying. These features are consistent with either a direct toxic effect of SSRIs and SNRIs or, possibly, a drug discontinuation syndrome. In some cases, the clinical picture was consistent with serotonin syndrome.
Exposure during late pregnancy to SSRIs may have an increased risk for persistent pulmonary hypertension of the newborn (PPHN). PPHN occurs in 1-2 per 1,000 live births in the general population and is associated with substantial neonatal morbidity and mortality. In a retrospective case-control study of 377 women whose infants were born with PPHN and 836 women whose infants were born healthy, the risk for developing PPHN was approximately six-fold higher for infants exposed to SSRIs after the 20th week of gestation compared to infants who had not been exposed to antidepressants during pregnancy. A study of 831,324 infants born in Sweden in 1997-2005 found a PPHN risk ratio of 2.4 (95% CI 1.2-4.3) associated with patient-reported maternal use of SSRIs “in early pregnancy” and a PPHN risk ratio of 3.6 (95% CI 1.2-8.3) associated with a combination of patient-reported maternal use of SSRIs “in early pregnancy” and an antenatal SSRI prescription “in later pregnancy”.
First Trimester Exposure
The weight of evidence from epidemiologic studies of pregnant women exposed to sertraline in the first trimester suggest no difference in major birth defect risk compared to the background rate for major birth defects in pregnant women who were not exposed to sertraline. A meta-analysis of studies suggest no increase in the risk of total malformations (summary odds ratio=1.01, 95% CI=0.88-1.17) or cardiac malformations (summary odds ratio=0.93, 95% CI=0.70-1.23) among offspring of women with first trimester exposure to sertraline. An increased risk of congenital cardiac defects, specifically septal defects, the most common type of congenital heart defect, was observed in some published epidemiologic studies with first trimester sertraline exposure; however, most of these studies were limited by the use of comparison populations that did not allow for the control of confounders such as the underlying depression and associated conditions and behaviors, which may be factors associated with increased risk of these malformations.
Animal Data
Reproduction studies have been performed in rats and rabbits at doses up to 80 mg/kg/day and 40 mg/kg/day, respectively. These doses correspond to approximately 3.1 times the maximum recommended human dose (MRHD) of 200 mg/day on a mg/m2 basis in adolescents. There was no evidence of teratogenicity at any dose level. When pregnant rats and rabbits were given sertraline during the period of organogenesis, delayed ossification was observed in fetuses at doses of 10 mg/kg (0.4 times the MRHD on a mg/m2 basis) in rats and 40 mg/kg (3.1 times the MRHD on a mg/m2 basis) in rabbits. When female rats received sertraline during the last third of gestation and throughout lactation, there was an increase in stillborn pups and pup deaths during the first 4 days after birth. Pup body weights were also decreased during the first four days after birth. These effects occurred at a dose of 20 mg/kg 0.8 times the MRHD on a mg/m2 basis). The no effect dose for rat pup mortality was 10 mg/kg (0.4 times the MRHD on a mg/m2 basis). The decrease in pup survival was shown to be due to in utero exposure to sertraline. The clinical significance of these effects is unknown.
Lactation
Risk Summary
Available data from published literature demonstrate low levels of sertraline and its metabolites in human milk [See Data]. There are no data on the effects of sertraline on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Moodapex and any potential adverse effects on the breastfed infant from the drug or from the underlying maternal condition.
Data
In a published pooled analysis of 53 mother-infant pairs, exclusively human milk-fed infants had an average of 2% (range 0% to 15%) of the sertraline serum levels measured in their mothers. No adverse reactions were observed in these infants.
Pediatric Use
The safety and efficacy of Moodapex have been established in the treatment of OCD in pediatric patients aged 6 to 17. Safety and effectiveness in pediatric patients in patients with OCD below the age of 6 have not been established. Safety and effectiveness have not been established in pediatric patients for indications other than OCD. Two placebo-controlled trials were conducted in pediatric patients with MDD, but the data were not sufficient to support an indication for use in pediatric patients.
Monitoring Pediatric Patients Treated With Moodapex
Monitor all patients being treated with antidepressants for clinical worsening, suicidal thoughts, and unusual changes in behavior, especially during the initial few months of treatment, or at times of dose increases or decreases. Decreased appetite and weight loss have been observed with the use of SSRIs. Monitor weight and growth in pediatric patients treated with an SSRI such as Moodapex.
Weight Loss In Studies In Pediatric Patients With MDD
In a pooled analysis of two 10-week, double-blind, placebo-controlled, flexible dose (50-200 mg) outpatient trials for MDD (n=373), there was a difference in weight change between Moodapex and placebo of roughly 1 kg, for both children (ages 6-11) and adolescents (ages 12-17), in both age groups representing a slight weight loss for the Moodapex group compared to a slight gain for the placebo group. For children, about 7% of the Moodapex-treated patients had a weight loss greater than 7% of body weight compared to 0% of the placebo-treated patients; for adolescents, about 2% of Moodapex-treated patients had a weight loss > 7% of body weight compared to about 1% of placebo-treated patients.
A subset of patients who completed the randomized controlled trials in patients with MDD (Moodapex n=99, placebo n=122) were continued into a 24-week, flexible-dose, open-label, extension study. Those subjects who completed 34 weeks of Moodapex treatment (10 weeks in a placebo-controlled trial + 24 weeks open-label, n=68) had weight gain that was similar to that expected using data from age-adjusted peers. However, there are no studies that directly evaluate the long-term effects of Moodapex on the growth, development, and maturation in pediatric patients.
Alcohol Content In Moodapex Oral Solution
Moodapex oral solution contains 12% alcohol.
Juvenile Animal Data
A study conducted in juvenile rats at clinically relevant doses showed delay in sexual maturation, but there was no effect on fertility in either males or females.
In this study in which juvenile rats were treated with oral doses of sertraline at 0, 10, 40 or 80 mg/kg/day from postnatal day 21 to 56, a delay in sexual maturation was observed in males treated with 80 mg/kg/day and females treated with doses ≥10 mg/kg/day. There was no effect on male and female reproductive endpoints or neurobehavioral development up to the highest dose tested (80 mg/kg/day), except a decrease in auditory startle response in females at 40 and 80 mg/kg/day at the end of treatment but not at the end of the drug –free period. The highest dose of 80 mg/kg/day produced plasma levels (AUC) of sertraline 5 times those seen in pediatric patients (6 -17 years of age) receiving the maximum recommended dose of sertraline (200 mg/day).
Geriatric Use
Of the total number of patients in clinical studies of Moodapex in patients with MDD, OCD, PD, PTSD, SAD and PMDD, 797 (17%) were ≥ 65 years old, while 197 (4%) were ≥ 75 years old.
No overall differences in safety or effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be conservative, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
In 354 geriatric subjects treated with Moodapex in MDD placebo-controlled trials, the overall profile of adverse reactions was generally similar to that shown in Table 3, except for tinnitus, arthralgia with an incidence of at least 2% and at a rate greater than placebo in geriatric patients.
SNRIs and SSRIs, including Moodapex, have been associated with cases of clinically significant hyponatremia in elderly patients, who may be at greater risk for this adverse reaction.
Hepatic Impairment
The recommended dosage in patients with mild hepatic impairment (Child-Pugh score 5 or 6) is half the recommended dosage due to increased exposure in this patient population. The use of Moodapex in patients with moderate (Child-Pugh score 7 to 10) or severe hepatic impairment (Child-Pugh score 10-15) is not recommended, because Moodapex is extensively metabolized, and the effects of Moodapex in patients with moderate and severe hepatic impairment have not been studied.
Renal Impairment
No dose adjustment is needed in patients with mild to severe renal impairment. Sertraline exposure does not appear to be affected by renal impairment.
The following adverse reactions are described in more detail in other sections of the prescribing information:
- Hypersensitivity reactions to sertraline
- Disulfiram-alcohol reaction when Moodapex oral solution is taken with disulfiram
- QTc prolongation and ventricular arrhythmias when taken with pimozide
- Suicidal thoughts and behaviors
- Serotonin syndrome
- Increased risk of bleeding
- Activation of mania/hypomania
- Discontinuation syndrome
- Seizures
- Angle-closure glaucoma
- Hyponatremia
Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
The data described below are from randomized, double-blind, placebo-controlled trials of Moodapex (mostly 50 mg to 200 mg per day) in 3066 adults diagnosed with MDD, OCD, PD, PTSD, SAD, and PMDD. These 3066 patients exposed to Moodapex for 8 to12 weeks represent 568 patient-years of exposure. The mean age was 40 years; 57% were females and 43% were males.
The most common adverse reactions (>5% and twice placebo) in all pooled placebo-controlled clinical trials of all Moodapex-treated patients with MDD, OCD, PD, PTSD, SAD and PMDD were nausea, diarrhea/loose stool, tremor, dyspepsia, decreased appetite, hyperhidrosis, ejaculation failure, and decreased libido (see Table 3). The following are the most common adverse reactions in trials of Moodapex (>5% and twice placebo) by indication that were not mentioned previously.
- MDD: somnolence;
- OCD: insomnia, agitation;
- PD: constipation, agitation;
- PTSD: fatigue;
- PMDD: somnolence, dry mouth, dizziness, fatigue, and abdominal pain;
- SAD: insomnia, dizziness, fatigue, dry mouth, malaise.

Adverse Reactions Leading To Discontinuation In Placebo-Controlled Clinical Trials
In all placebo-controlled studies in patients with MDD, OCD, PD, PTSD, SAD and PMDD, 368 (12%) of the 3066 patients who received Moodapex discontinued treatment due to an adverse reaction, compared with 93 (4%) of the 2293 placebo-treated patients. In placebo-controlled studies, the following were the common adverse reactions leading to discontinuation in Moodapex-treated patients:
- MDD, OCD, PD, PTSD, SAD and PMDD: nausea (3%), diarrhea (2%), agitation (2%), and insomnia (2%).
- MDD (>2% and twice placebo): decreased appetite, dizziness, fatigue, headache, somnolence, tremor, and vomiting.
- OCD: somnolence.
- PD: nervousness and somnolence.
Male And Female Sexual Dysfunction
Although changes in sexual desire, sexual performance and sexual satisfaction often occur as manifestations of a psychiatric disorder, they may also be a consequence of SSRI treatment. However, reliable estimates of the incidence and severity of untoward experiences involving sexual desire, performance and satisfaction are difficult to obtain, in part because patients and healthcare providers may be reluctant to discuss them. Accordingly, estimates of the incidence of untoward sexual experience and performance cited in labeling may underestimate their actual incidence.
Table 4 below displays the incidence of sexual adverse reactions reported by at least 2% of Moodapex-treated patients and twice placebo from pooled placebo-controlled trials. For men and all indications, the most common adverse reactions (>2% and twice placebo) included: ejaculation failure, decreased libido, erectile dysfunction, ejaculation disorder, and male sexual dysfunction. For women, the most common adverse reaction (≥2% and twice placebo) was decreased libido.

Adverse Reactions In Pediatric Patients
In 281 pediatric patients treated with Moodapex in placebo-controlled studies, the overall profile of adverse reactions was generally similar to that seen in adult studies. Adverse reactions that do not appear in Table 3 (most common adverse reactions in adults) yet were reported in at least 2% of pediatric patients and at a rate of at least twice the placebo rate include fever, hyperkinesia, urinary incontinence, aggression, epistaxis, purpura, arthralgia, decreased weight, muscle twitching, and anxiety.

Vascular disorders - cerebrovascular spasm (including reversible cerebral vasoconstriction syndrome and Call-Fleming syndrome), vasculitis
Human Experience
The most common signs and symptoms associated with non-fatal Moodapex overdosage were somnolence, vomiting, tachycardia, nausea, dizziness, agitation and tremor. No cases of fatal overdosage with only sertraline have been reported.
Other important adverse events reported with Moodapex overdose (single or multiple drugs) include bradycardia, bundle branch block, coma, convulsions, delirium, hallucinations, hypertension, hypotension, manic reaction, pancreatitis, QTc-interval prolongation, Torsade de Pointes, serotonin syndrome, stupor, and syncope.
Overdose Management
No specific antidotes for Moodapex are known. Contact Poison Control (1-800-222-1222) for latest recommendations.
Studies at clinically relevant doses have demonstrated that sertraline blocks the uptake of serotonin into human platelets. In vitro studies in animals also suggest that sertraline is a potent and selective inhibitor of neuronal serotonin reuptake and has only very weak effects on norepinephrine and dopamine neuronal reuptake. In vitro studies have shown that sertraline has no significant affinity for adrenergic (alpha1, alpha2, beta), cholinergic, GABA, dopaminergic, histaminergic, serotonergic (5HT1A, 5HT1B, 5HT2), or benzodiazepine receptors. The chronic administration of sertraline was found in animals to down regulate brain norepinephrine receptors. Sertraline does not inhibit monoamine oxidase.
Alcohol
In healthy subjects, the acute cognitive and psychomotor effects of alcohol were not potentiated by Moodapex.
Cardiac Electrophysiology
The effect of sertraline on the QTc interval was evaluated in a randomized, double-blind, placebo- and positive-controlled three-period crossover thorough QTc study in 54 healthy adult subjects. At 2-fold the maximum recommended daily dose (~3-fold the steady-state exposure for sertraline and N-desmethylsertraline), the largest mean ΔΔQTc was 10 ms with upper bound of two-sided 90% confidence interval of 12 ms. The length of the QTc interval was also positively correlated with serum concentrations of sertraline and N- desmethylsertraline concentrations. These concentration-based analyses, however, indicated a lesser effect on QTc at maximally observed concentration than in the primary analysis.
Absorption
Following oral once-daily Moodapex dosing over the range of 50 to 200 mg for 14 days, mean peak plasma concentrations (Cmax) of sertraline occurred between 4.5 to 8.4 hours post-dosing. The average terminal elimination half-life of plasma sertraline is about 26 hours. Consistent with the terminal elimination half-life, there is an approximately two-fold accumulation up to steady-state concentrations, which are achieved after one week of once-daily dosing. Linear dose-proportional pharmacokinetics were demonstrated in a single dose study in which the Cmax and area under the plasma concentration time curve (AUC) of sertraline were proportional to dose over a range of 50 to 200 mg. The single dose bioavailability of Moodapex tablets is approximately equal to an equivalent dose of Moodapex oral solution. Administration with food causes a small increase in Cmax and AUC.
Metabolism
Sertraline undergoes extensive first pass metabolism. The principal initial pathway of metabolism for sertraline is N-demethylation. N-desmethylsertraline has a plasma terminal elimination half-life of 62 to 104 hours. Both in vitro biochemical and in vivo pharmacological testing have shown N-desmethylsertraline to be substantially less active than sertraline. Both sertraline and N-desmethylsertraline undergo oxidative deamination and subsequent reduction, hydroxylation, and glucuronide conjugation. In a study of radiolabeled sertraline involving two healthy male subjects, sertraline accounted for less than 5% of the plasma radioactivity. About 40-45% of the administered radioactivity was recovered in urine in 9 days. Unchanged sertraline was not detectable in the urine. For the same period, about 40-45% of the administered radioactivity was accounted for in feces, including 12-14% unchanged sertraline.
Desmethylsertraline exhibits time-related, dose dependent increases in AUC (0-24-hour), Cmax and Cmin, with about a 5- to 9-fold increase in these pharmacokinetic parameters between day 1 and day 14.
Protein Binding
In vitro protein binding studies performed with radiolabeled 3H-sertraline showed that sertraline is highly bound to serum proteins (98%) in the range of 20 to 500 ng/mL. However, at up to 300 and 200 ng/mL concentrations, respectively, sertraline and N-desmethylsertraline did not alter the plasma protein binding of two other highly protein bound drugs, warfarin and propranolol.
However, we will provide data for each active ingredient
