Severe Recalcitrant Nodular Acne

Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) is indicated for the treatment of severe recalcitrant nodular acne. Nodules are inflammatory lesions with a diameter of 5 mm or greater. The nodules may become suppurative or hemorrhagic. "Severe," by definition,² means "many" as opposed to "few or several" nodules. Because of significant adverse effects associated with its use. Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) should be reserved for patients with severe nodular acne who are unresponsive to conventional therapy, including systemic antibiotics. In addition, Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) is indicated only for those female patients who are not pregnant, because Sotret can cause severe birth defects (see Boxed CONTRAINDICATIONS AND WARNINGS).

A single course of therapy for 15 to 20 weeks has been shown to result in complete and prolonged remission of disease in many patients._1,3,4 If a second course of therapy is needed, it should not be initiated until at least 8 weeks after completion of the first course, because experience has shown that patients may continue to improve while off isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin capsules. The optimal interval before retreatment has not been defined for patients who have not completed skeletal growth (see WARNINGS: Skeletal: Bone Mineral Density, Hyperostosis, and Premature Epiphyseal Closure).

Sotret should be administered with a meal (see PATIENT INFORMATION).

The recommended dosage range for Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) is 0.5 to 1.0 mg/kg/day given in two divided doses with food for 15 to 20 weeks. In studies comparing 0.1, 0.5, and 1 mg/kg/day⁸, it was found that all dosages provided initial clearing of disease, but there was a greater need for retreatment with the lower dosages. During treatment, the dose may be adjusted according to response of the disease and/or the appearance of clinical side effects — some of which may be dose related. Adult patients whose disease is very severe with scarring or is primarily manifested on the trunk may require dose adjustments up to 2.0 mg/kg/day, as tolerated. Failure to take Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) with food will significantly decrease absorption. Before upward dose adjustments are made, the patients should be questioned about their compliance with food instructions.

The safety of once daily dosing with Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) has not been established. Once daily dosing is not recommended.

If the total nodule count has been reduced by more than 70% prior to completing 15 to 20 weeks of treatment, the drug may be discontinued. After a period of 2 months or more off therapy, and if warranted by persistent or recurring severe nodular acne, a second course of therapy may be initiated. The optimal interval before retreatment has not been defined for patients who have not completed skeletal growth. Long-term use of Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) , even in low doses, has not been studied, and is not recommended. It is important that Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) be given at the recommended doses for no longer than the recommended duration. The effect of long-term use of Sotret on bone loss is unknown (see WARNINGS: Skeletal: Bone Mineral Density, Hyperostosis, and Premature Epiphyseal Closure). Contraceptive measures must be followed for any subsequent course of therapy (see PRECAUTIONS).

This Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) Medication Guide is an important part of the risk management program for the patient.

Pregnancy: Category X.

See Boxed CONTRAINDICATIONS AND WARNINGS.

Allergic Reactions

Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) is contraindicated in patients who are hypersensitive to this medication or to any of its components. Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) should not be given to patients who are sensitive to parabens, which are used as preservatives in the gelatin capsule (see PRECAUTIONS: Hypersensitivity).

WARNINGS

Psychiatric Disorders

Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) may cause depression, psychosis and, rarely, suicidal ideation, suicide attempts, suicide, and aggressive and/or violent behaviors. No mechanism of action has been established for these events (see ADVERSE REACTIONS: Psychiatric). Prescribers should read the brochure, Recognizing Psychiatric Disorders in Adolescents and Young Adults: A Guide for Prescribers of lsotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin. Prescribers should be alert to the warning signs of psychiatric disorders to guide patients to receive the help they need. Therefore, prior to initiation of Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) therapy, patients and family members should be asked about any history of psychiatric disorder, and at each visit during therapy patients should be assessed for symptoms of depression, mood disturbance, psychosis, or aggression to determine if further evaluation maybe necessary. Signs and symptoms of depression, as described in the brochure ("Recognizing Psychiatric Disorders in Adolescents and Young Adults"), include sad mood, hopelessness, feelings of guilt, worthlessness or helplessness, loss of pleasure or interest in activities, fatigue, difficulty concentrating, change in sleep pattern, change in weight or appetite, suicidal thoughts or attempts, restlessness, irritability, acting on dangerous impulses, and persistent physical symptoms unresponsive to treatment. Patients should stop Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) and the patient or a family member should promptly contact their prescriber if the patient develops depression, mood disturbance, psychosis, or aggression, without waiting until the next visit. Discontinuation of Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) therapy may be insufficient; further evaluation may be necessary. While such monitoring may be helpful, it may not detect all patients at risk. Patients may report mental health problems or family history of psychiatric disorders. These reports should be discussed with the patient and/ or the patient's family. A referral to a mental health professional may be necessary. The physician should consider whether Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) therapy is appropriate in this setting; for some patients the risks may outweigh the benefits of isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin therapy.

Pseudotumor Cerebri

Isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin capsule use has been associated with a number of cases of pseudotumor cerebri (benign intracranial hypertension), some of which involved concomitant use of tetracyclines. Concomitant treatment with tetracyclines should therefore be avoided. Early signs and symptoms of pseudotumor cerebri include papilledema, headache, nausea and vomiting, and visual disturbances. Patients with these symptoms should be screened for papilledema and, if present, they should be told to discontinue Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) immediately and be referred to a neurologist for further diagnosis and care (see ADVERSE REACTIONS: Neurological).

Pancreatitis

Acute pancreatitis has been reported in patients with either elevated or normal serum triglyceride levels. In rare instances, fatal hemorrhagic pancreatitis has been reported. Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) should be stopped if hypertriglyceridemia cannot be controlled at an acceptable level or if symptoms of pancreatitis occur.

Lipids

Elevations of serum triglycerides in excess of 800 mg/dL have been reported in patients treated with isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin capsules. Marked elevations of serum triglycerides were reported in approximately 25% of patients receiving isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin capsules in clinical trials. In addition, approximately 15% developed a decrease in high-density lipoproteins and about 7% showed an increase in cholesterol levels. In clinical trials, the effects on triglycerides, HDL, and cholesterol were reversible upon cessation of isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin capsules therapy. Some patients have been able to reverse triglyceride elevation by reduction in weight, restriction of dietary fat and alcohol, and reduction in dose while continuing isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin capsules.⁵

Blood lipid determinations should be performed before Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) is given and then at intervals until the lipid response to Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) is established, which usually occurs within 4 weeks. Especially careful consideration must be given to risk/benefit for patients who may be at high risk during Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) therapy (patients with diabetes, obesity, increased alcohol intake, lipid metabolism disorder or familial history of lipid metabolism disorder). If Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) therapy is instituted, more frequent checks of serum values for lipids and/or blood sugar are recommended (see PRECAUTIONS: Laboratory Tests).

The cardiovascular consequences of hypertriglyceridemia associated with Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) are unknown.

Animal Studies: In rats given 8 or 32 mg/kg/day of isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin (1.3 to 5.3 times the recommended clinical dose of 1.0 mg/kg/day after normalization for total body surface area) for 18 months or longer, the incidences of focal calcification, fibrosis and inflammation of the myocardium, calcification of coronary, pulmonary and mesenteric arteries, and metastatic calcification of the gastric mucosa were greater than in control rats of similar age. Focal endocardial and myocardial calcifications associated with calcification of the coronary arteries were observed in two dogs after approximately 6 to 7 months of treatment with isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin at a dosage of 60 to 120 mg/kg/ day (30 to 60 times the recommended clinical dose of 1.0 mg/kg/day, respectively, after normalization for total body surface area).

Hearing Impairment

Impaired hearing has been reported in patients taking isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin capsules; in some cases, the hearing impairment has been reported to persist after therapy has been discontinued. Mechanism(s) and causality for this event have not been established. Patients who experience tinnitus or hearing impairment should discontinue Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) treatment and be referred for specialized care for further evaluation (see ADVERSE REACTIONS: Special Senses).

Hepatotoxicity

Clinical hepatitis considered to be possibly or probably related to isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin capsules therapy has been reported. Additionally, mild to moderate elevations of liver enzymes have been observed in approximately 15% of individuals treated during clinical trials, some of which normalized with dosage reduction or continued administration of the drug. If normalization does not readily occur or if hepatitis is suspected during treatment with Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) , the drug should be discontinued and the etiology further investigated.

Inflammatory Bowel Disease

Isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin capsules have been associated with inflammatory bowel disease (including regional ileitis) in patients without a prior history of intestinal disorders. In some instances, symptoms have been reported to persist after isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin capsules treatment has been stopped. Patients experiencing abdominal pain, rectal bleeding or severe diarrhea should discontinue Sotret immediately (see ADVERSE REACTIONS: Gastrointestinal).

Skeletal

Bone Mineral Density

Effects of multiple courses of Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) on the developing musculoskeletal system are unknown. There is some evidence that long-term, high-dose, or multiple courses of therapy with isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin have more of an effect than a single course of therapy on the musculoskeletal system. In an open-label clinical trial (N=217) of a single course of therapy with isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin for severe recalcitrant nodular acne, bone density measurements at several skeletal sites were not significantly decreased (lumbar spine change > -4% and total hip change > -5%) or were increased in the majority of patients. One patient had a decrease in lumbar spine bone mineral density > 4% based on unadjusted data. Sixteen (7.9%) patients had decreases in lumbar spine bone mineral density > 4%, and all the other patients (92%) did not have significant decreases or had increases (adjusted for body mass index). Nine patients (4.5%) had a decrease in total hip bone mineral density > 5% based on unadjusted data. Twenty-one (10.6%) patients had decreases in total hip bone mineral density > 5%, and all the other patients (89%) did not have significant decreases or had increases (adjusted for body mass index). Follow-up studies performed in 8 of the patients with decreased bone mineral density for up to 11 months thereafter demonstrated increasing bone density in 5 patients at the lumbar spine, while the other 3 patients had lumbar spine bone density measurements below baseline values. Total hip bone mineral densities remained below baseline (range -1.6% to -7.6%) in 5 of 8 patients (62.5%).

In a separate open-label extension study of 10 patients, ages 13 to 18 years, who started a second course of isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin 4 months after the first course, two patients showed a decrease in mean lumbar spine bone mineral density up to 3.25% (see PRECAUTIONS: Pediatric Use).

Spontaneous reports of osteoporosis, osteopenia, bone fractures, and delayed healing of bone fractures have been seen in the isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin population. While causality to Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) has not been established, an effect cannot be ruled out. Longer term effects have not been studied. It is important that Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) be given at the recommended doses for no longer than the recommended duration.

Hyperostosis

A high prevalence of skeletal hyperostosis was noted in clinical trials for disorders of keratinization with a mean dose of 2.24 mg/kg/day. Additionally, skeletal hyperostosis was noted in 6 of 8 patients in a prospective study of disorders of keratinization.⁶ Minimal skeletal hyperostosis and calcification of ligaments and tendons have also been observed by x-ray in prospective studies of nodular acne patients treated with a single course of therapy at recommended doses. The skeletal effects of multiple Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) treatment courses for acne are unknown.

In a clinical study of 217 pediatric patients (12 to 17 years) with severe recalcitrant nodular acne, hyperostosis was not observed after 16 to 20 weeks of treatment with approximately 1 mg/kg/day of isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin capsules given in two divided doses. Hyperostosis may require a longer time frame to appear. The clinical course and significance remain unknown.

Premature Epiphyseal Closure

There are spontaneous reports of premature epiphyseal closure in acne patients receiving recommended doses of isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin capsules.

The effect of multiple courses of Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) on epiphyseal closure is unknown.

Vision Impairment

Visual problems should be carefully monitored. All Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) patients experiencing visual difficulties should discontinue Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) treatment and have an ophthalmological examination (see ADVERSE REACTIONS: Special Senses).

Corneal Opacities

Corneal opacities have occurred in patients receiving isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin capsules for acne and more frequently when higher drug dosages were used in patients with disorders of keratinization. The corneal opacities that have been observed in clinical trial patients treated with isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin capsules have either completely resolved or were resolving at follow-up 6 to 7 weeks after discontinuation of the drug (see ADVERSE REACTIONS: Special Senses).

Decreased Night Vision

Decreased night vision has been reported during isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin capsules therapy and in some instances the event has persisted after therapy was discontinued. Because the onset in some patients was sudden, patients should be advised of this potential problem and warned to be cautious when driving or operating any vehicle at night.

PRECAUTIONS

Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) must only be prescribed by prescribers who are registered and activated with the iPLEDGE program. Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) must only be dispensed by a pharmacy registered and activated with iPLEDGE, and must only be dispensed to patients who are registered and meet all the requirements of iPLEDGE. Registered and activated pharmacies must receive isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin only from wholesalers registered with iPLEDGE.

iPLEDGE program requirements for wholesalers, prescribers, and pharmacists are described below:

Wholesalers

For the purpose of the iPLEDGE program, the term wholesaler refers to wholesaler, distributor, and/or chain pharmacy distributor. To distribute Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) , wholesalers must be registered with iPLEDGE, and agree to meet all iPLEDGE requirements for wholesale distribution of isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin products. Wholesalers must register with iPLEDGE by signing and returning the iPLEDGE wholesaler agreement that affirms they will comply with all iPLEDGE requirements for distribution of isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin. These include:

• Registering prior to distributing isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin and reregistering annually thereafter
• Distributing only FDA approved isotretinoin product
• Only shipping isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin to
• wholesalers registered in the iPLEDGE program with prior written consent from the manufacturer
• pharmacies licensed in the US and registered and activated in the iPLEDGE program
• Notifying the isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin manufacturer (or delegate) of any non-registered and/or non-activated pharmacy or unregistered wholesaler that attempts to order isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin
• Complying with inspection of wholesaler records for verification of compliance with the iPLEDGE program by the isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin manufacturer (or delegate)
• Returning to the manufacturer (or delegate) any undistributed product if registration is revoked by the manufacturer or if the wholesaler chooses to not reregister annually
• Providing product flow data to manufacturer (or delegate) as detailed in the wholesalers agreement

Prescribers

To prescribe isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin, the prescriber must be registered and activated with the pregnancy risk management program iPLEDGE. Prescribers can register by signing and returning the completed registration form. Prescribers can only activate their registration by affirming that they meet requirements and will comply with all iPLEDGE requirements by attesting to the following points:

• I know how to diagnose and treat the various presentations of acne.
• I know the risk and severity of fetal injury/birth defects from isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin.
• I know the risk factors for unplanned pregnancy and the effective measures for avoidance of unplanned pregnancy.
• I have the expertise to provide the patient with detailed pregnancy prevention counseling or I will refer her to an expert for such counseling, reimbursed by the manufacturer.
• I will comply with the iPLEDGE program requirements described in the booklets entitled The iPLEDGE Program Guide to Best Practices for Isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin and The iPLEDGE Program Prescriber Contraception Counseling Guide.
• Before beginning treatment of female patients of childbearing potential with isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin and on a monthly basis, the patient will be counseled to avoid pregnancy by using two forms of contraception simultaneously and continuously one month before, during, and one month after isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin therapy, unless the patient commits to continuous abstinence.
• I will not prescribe isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin to any female patient of childbearing potential until verifying she has a negative screening pregnancy test and monthly negative CLIA-certified (Clinical Laboratory Improvement Amendment) pregnancy tests. Patients should have a pregnancy test at the completion of the entire course of isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin and another pregnancy test 1 month later.
• I will report any pregnancy case that I become aware of while the female patient is on isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin or 1 month after the last dose to the pregnancy registry.

To prescribe isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin, the prescriber must access the iPLEDGE system via the internet (www.ipledgeprogram.com) or telephone (1-866-495-0654) to:

1. Register each patient in the iPLEDGE program.
2. Confirm monthly that each patient has received counseling and education.
3. For female patients of childbearing potential:
   • Enter patient's two chosen forms of contraception each month.
   • Enter monthly result from CLIA-certified laboratory conducted pregnancy test.

Isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin must only be prescribed to female patients who are known not to be pregnant as confirmed by a negative CLIA-certified laboratory conducted pregnancy test.

Isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin must only be dispensed by a pharmacy registered and activated with the pregnancy risk management program iPLEDGE and only when the registered patient meets all the requirements of the iPLEDGE program. Meeting the requirements for a female patient of childbearing potential signifies that she:

• Has been counseled and has signed a Patient Information/Informed Consent About Birth Defects (for female patients who can get pregnant) form that contains warnings about the risk of potential birth defects if the fetus is exposed to isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin. The patient must sign the informed consent form before starting treatment and patient counseling must also be done at that time and on a monthly basis thereafter.
• Has had two negative urine or serum pregnancy tests with a sensitivity of at least 25 mlU/mL before receiving the initial isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin prescription. The first test (a screening test) is obtained by the prescriber when the decision is made to pursue qualification of the patient for isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin. The second pregnancy test (a confirmation test) must be done in a CLIA-certified laboratory. The interval between the 2 tests should be at least 19 days.
• For patients with regular menstrual cycles, the second pregnancy test should be done during the first 5 days of the menstrual period and within 7 days of the office visit, immediately preceding the beginning of isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin therapy and after the patient has used 2 forms of contraception for 1 month.
• For patients with amenorrhea, irregular cycles, or using a contraceptive method that precludes withdrawal bleeding, the second pregnancy test must be done within 7 days following the office visit, immediately preceding the beginning of isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin therapy and after the patient has used 2 forms of contraception for 1 month.
• Has had a negative result from a urine or serum pregnancy test in a CLIA-certified laboratory before receiving each subsequent course of isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin. A pregnancy test must be repeated every month, in a CLIA-certified laboratory, prior to the female patient receiving each prescription.
• Has selected and has committed to use 2 forms of effective contraception simultaneously, at least 1 of which must be a primary form, unless the patient commits to continuous abstinence from heterosexual contact, or the patient has undergone a hysterectomy or bilateral oophorectomy, or has been medically confirmed to be post-menopausal. Patients must use 2 forms of effective contraception for at least 1 month prior to initiation of isotretinoin therapy, during isotret (isotret (isotretinoin capsules) inoin capsules) inoin therapy, and for 1 month after discontinuing isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin therapy. Counseling about contraception and behaviors associated with an increased risk of pregnancy must be repeated on a monthly basis.

If the patient has unprotected heterosexual intercourse at any time 1 month before, during, or 1 month after therapy, she must:

1. Stop taking isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin immediately, if on therapy
2. Have a pregnancy test at least 19 days after the last act of unprotected heterosexual intercourse
3. Start using 2 forms of effective contraception simultaneously again for 1 month before resuming isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin therapy
4. Have a second pregnancy test after using 2 forms of effective contraception for 1 month as described above depending on whether she has regular menses or not.

Effective forms of contraception include both primary and secondary forms of contraception:

Any birth control method can fail. There have been reports of pregnancy from female patients who have used oral contraceptives, as well as transdermal patch/injectable/implantable/vaginal ring hormonal birth control products; these pregnancies occurred while these patients were taking isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin capsules. These reports are more frequent for female patients who use only a single method of contraception. Therefore, it is critically important that female patients of childbearing potential use 2 effective forms of contraception simultaneously. Patients must receive written warnings about the rates of possible contraception failure (included in patient education kits).

Using two forms of contraception simultaneously substantially reduces the chances that a female will become pregnant over the risk of pregnancy with either form alone. A drug interaction that decreases effectiveness of hormonal contraceptives has not been entirely ruled out for Sotret (see PRECAUTIONS: DRUG INTERACTIONS). Although hormonal contraceptives are highly effective, prescribers are advised to consult the package insert of any medication administered concomitantly with hormonal contraceptives, since some medications may decrease the effectiveness of these birth control products.

Patients should be prospectively cautioned not to self-medicate with the herbal supplement St. John's Wort because a possible interaction has been suggested with hormonal contraceptives based on reports of breakthrough bleeding on oral contraceptives shortly after starting St. John's Wort. Pregnancies have been reported by users of combined hormonal contraceptives who also used some form of St. John's Wort.

If a pregnancy does occur during isotretinoin treatment, isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin must be discontinued immediately. The patient should be referred to an Obstetrician-Gynecologist experienced in reproductive toxicity for further evaluation and counseling. Any suspected fetal exposure during or 1 month after isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin therapy must be reported immediately to the FDA via the MedWatch number 1-800-FDA- 1088 and also to the iPLEDGE pregnancy registry at 1-866-495-0654 or via the internet (www.ipledgeprogram.com).

SIDE EFFECTS

Clinical Trials and Postmarketing Surveillance

The adverse reactions listed below reflect the experience from investigational studies of isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin capsules, and the postmarketing experience. The relationship of some of these events to isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin capsules therapy is unknown. Many of the side effects and adverse reactions seen in patients receiving isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin capsules are similar to those described in patients taking very high doses of vitamin A (dryness of the skin and mucous membranes, e.g., of the lips, nasal passage, and eyes).

DRUG INTERACTIONS

• Vitamin A: Because of the relationship of Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) to vitamin A, patients should be advised against taking vitamin supplements containing vitamin A to avoid additive toxic effects.
• Tetracyclines: Concomitant treatment with Sotret (isotretinoin capsules) and tetracyclines should be avoided because isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin capsule use has been associated with a number of cases of pseudotumor cerebri (benign intracranial hypertension), some of which involved concomitant use of tetracyclines.
• Micro-dosed Progesterone Preparations: Micro-dosed progesterone preparations ("minipills" that do not contain an estrogen) may be an inadequate method of contraception during Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) therapy. Although other hormonal contraceptives are highly effective, there have been reports of pregnancy from female patients who have used combined oral contraceptives, as well as transdermal patch/injectable/implantable/vaginal ring hormonal birth control products. These reports are more frequent for female patients who use only a single method of contraception. It is not known if hormonal contraceptives differ in their effectiveness when used with isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin. Therefore, it is critically important for female patients of childbearing potential to select and commit to use 2 forms of effective contraception simultaneously, at least 1 of which must be a primary form (see PRECAUTIONS).
• Norethindrone/ethinyl estradiol: In a study of 31 premenopausal female patients with severe recalcitrant nodular acne receiving OrthoNovum®, 7/7/7 Tablets as an oral contraceptive agent, isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin at the recommended dose of 1 mg/kg/day, did not induce clinically relevant changes in the pharmacokinetics of ethinyl estradiol and norethindrone and in the serum levels of progesterone, follicle stimulating hormone (FSH) and luteinizing hormone (LH). Prescribers are advised to consult the package insert of medication administered concomitantly with hormonal contraceptives, since some medications may decrease the effectiveness of these birth control products.
• St. John's Wort: Isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin capsules use is associated with depression in some patients (see WARNINGS: Psychiatric Disorders and ADVERSE REACTIONS: Psychiatric). Patients should be prospectively cautioned not to self-medicate with the herbal supplement St. John's Wort because a possible interaction has been suggested with hormonal contraceptives based on reports of breakthrough bleeding on oral contraceptives shortly after starting St. John's Wort. Pregnancies have been reported by users of combined hormonal contraceptives who also used some form of St. John's Wort.
• Phenytoin: Isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin capsules have not been shown to alter the pharmacokinetics of phenytoin in a study in seven healthy volunteers. These results are consistent with the in vitro finding that neither isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin nor its metabolites induce or inhibit the activity of the CYP 2C9 human hepatic P450 enzyme. Phenytoin is known to cause osteomalacia. No formal clinical studies have been conducted to assess if there is an interactive effect on bone loss between phenytoin and isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin. Therefore, caution should be exercised when using these drugs together.
• Systemic Corticosteroids: Systemic corticosteroids are known to cause osteoporosis. No formal clinical studies have been conducted to assess if there is an interactive effect on bone loss between systemic corticosteroids and Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules). Therefore, caution should be exercised when using these drugs together.

Laboratory Tests

• Pregnancy Test
• Female patients of childbearing potential must have had two negative urine or serum pregnancy tests with a sensitivity of at least 25 mlU/mL before receiving the initial Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) prescription. The first test (a screening test) is obtained by the prescriber when the decision is made to pursue qualification of the patient for Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules). The second pregnancy test (a confirmation test) must be done in a CLIA-certified laboratory. The interval between the two tests must be at least 19 days.
• For patients with regular menstrual cycles, the second pregnancy test must be done during the first 5 days of the menstrual period and within 7 days following the office visit, immediately preceding the beginning of Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) therapy and after the patient has used 2 forms of contraception for 1 month.
• For patients with amenorrhea, irregular cycles, or using a contraceptive method that precludes withdrawal bleeding, the second pregnancy test must be done within 7 days following the office visit, immediately preceding the beginning of Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) therapy and after the patient has used 2 forms of contraception for 1 month.
• Each month of therapy, patients must have a negative result from a urine or serum pregnancy test. A pregnancy test must be repeated each month, in a CLIA-certified laboratory, prior to the female patient receiving each prescription.
• Lipids: Pretreatment and follow-up blood lipids should be obtained under fasting conditions. After consumption of alcohol, at least 36 hours should elapse before these determinations are made. It is recommended that these tests be performed at weekly or biweekly intervals until the lipid response to Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) is established. The incidence of hypertriglyceridemia is 1 patient in 4 on isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin therapy (see WARNINGS: Lipids).
• Liver Function Tests: Since elevations of liver enzymes have been observed during clinical trials, and hepatitis has been reported, pretreatment and follow-up liver function tests should be performed at weekly or biweekly intervals until the response to Sotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) has been established (see WARNINGS: Hepatotoxicity).
• Glucose: Some patients receiving isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin capsules have experienced problems in the control of their blood sugar. In addition, new cases of diabetes have been diagnosed during isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin capsule therapy, although no causal relationship has been established.
• CPK: Some patients undergoing vigorous physical activity while on isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin capsules therapy have experienced elevated CPK levels; however, the clinical significance is unknown. There have been rare postmarketing reports of rhabdomyolysis, some associated with strenuous physical activity. In a clinical trial of 217 pediatric patients (12 to 17 years) with severe recalcitrant nodular acne, transient elevations in CPK were observed in 12% of patients, including those undergoing strenuous physical activity in association with reported musculoskeletal adverse events such as back pain, arthralgia, limb injury, or muscle sprain. In these patients, approximately half of the CPK elevations returned to normal within 2 weeks and half returned to normal within 4 weeks. No cases of rhabdomyolysis were reported in this trial.

The oral LD₅₀ of isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin is greater than 4000 mg/kg in rats and mice ( > 600 times the recommended clinical dose of 1.0 mg/ kg/day after normalization of the rat dose for total body surface area and > 300 times the recommended clinical dose of 1.0 mg/ kg/day after normalization of the mouse dose for total body surface area) and is approximately 1960 mg/kg in rabbits (653 times the recommended clinical dose of 1 mg/kg/day after normalization for total body surface area). In humans, overdosage has been associated with vomiting, facial flushing, cheilosis, abdominal pain, headache, dizziness, and ataxia. These symptoms quickly resolve without apparent residual effects.

Isotret (isotret (isotret (isotretinoin capsules) inoin capsules) inoin capsules) inoin causes serious birth defects at any dosage (see Boxed
