Overview of Cilodral (Citalopram)

What Type of Medicine is Citalopram (Cilodral)?

Citalopram is an antidepressant medication classified as a Selective Serotonin Reuptake Inhibitor (SSRI). Its primary pharmacological role is to influence chemical messengers in the brain to help regulate and stabilize mood in adults. This medication works through a targeted action on the central nervous system's serotonin pathways.

The active chemical entity, Citalopram, is a synthetic compound supplied as the salt Citalopram hydrobromide. A key characteristic of Citalopram among SSRIs is its high degree of selectivity toward serotonin reuptake inhibition, demonstrating minimal interaction with norepinephrine or dopamine receptors. This focus on serotonin is the specific mechanism intended to enhance serotonergic activity, which is essential for emotional balance. Its inclusion in the WHO Model List of Essential Medicines reflects its significance and widespread use in global healthcare.

Composition, Form, and General Purpose

Citalopram is administered as a single-ingredient product designed for oral intake. The preparation is available as standard oral tablets and also as an oral solution or oral drops, providing options for individuals who may have difficulty swallowing solid medication.

The composition utilizes the active Citalopram base derived from the hydrobromide salt, combined with non-active excipients necessary for the stability of the dosage form. The medication's general therapeutic purpose is to help restore chemical balance by increasing available serotonin, which assists in alleviating symptoms associated with certain depressive and anxiety-related conditions. Compared to some older antidepressant classes, Citalopram is characterized by a low potential for drug-drug interactions due to its minimal effect on key liver enzymes.

What side effects are possible with Cilodral (Citalopram)?

Cilodral (Citalopram) is a selective serotonin reuptake inhibitor (SSRI) used to treat depression and is associated with a range of possible side effects and important safety warnings.

Serious Warnings and Precautions

Citalopram carries a Boxed Warning regarding the increased risk of suicidal thoughts and behavior in children, adolescents, and young adults (up to age 24) when starting treatment or when the dosage is changed. Patients of all ages should be closely monitored for clinical worsening, agitation, or unusual changes in behavior.

Another significant concern is QT interval prolongation, which is a dose-dependent effect on the heart's electrical activity that can lead to an abnormal, potentially fatal heart rhythm (Torsade de Pointes). For most patients, the maximum recommended daily dose is 40 mg. A maximum dose of 20 mg per day is recommended for patients over 60 years of age, those with hepatic impairment, or those taking certain interacting medications (like cimetidine).

Common Side Effects

Side effects are generally mild to moderate and often lessen over time. The most commonly reported side effects include:

  • Gastrointestinal: Nausea, dry mouth, diarrhea, constipation.
  • Nervous System: Drowsiness, insomnia, headache, dizziness.
  • Other: Increased sweating, reduced sexual desire or function, and ejaculation disorder (primarily delay) in males.

Important Safety Information

  • Serotonin Syndrome: A potentially life-threatening condition that can occur when Citalopram is used with other serotonergic drugs (e.g., MAOIs, triptans, or St. John's wort). Symptoms may include agitation, hallucinations, fever, muscle stiffness, and a rapid heart rate. Citalopram must not be taken with MAO inhibitors.
  • Bleeding Risk: Citalopram may increase the risk of bleeding or bruising, particularly when taken with non-steroidal anti-inflammatory drugs (NSAIDs) or blood thinners.
  • Withdrawal: Stopping Citalopram suddenly can cause withdrawal symptoms such as dizziness, mood changes, and sensory disturbances; the dosage should be tapered gradually under a healthcare provider’s direction.
  • Hypersensitivity: Rare cases of severe allergic reactions (e.g., angioedema) have been reported.

Overdose and Emergency Response

Overdose and When to Seek Help

This section outlines information regarding Citalopram overdose strictly based on authoritative regulatory documents and is not a substitute for immediate medical advice.


Documented Overdose Manifestations

Citalopram overdose can lead to a range of symptoms, predominantly affecting the cardiovascular and central nervous systems. Documented signs include seizures, excessive somnolence (drowsiness), tremor, nausea, and vomiting. More severe manifestations, particularly with high doses, include QT-prolongation (an electrical disturbance of the heart), Torsade de Pointes (a potentially fatal heart rhythm), and coma.

Immediate Actions and Management

There is no specific antidote for Citalopram overdose. Treatment is primarily symptomatic and supportive, focusing on maintaining airway, breathing, and circulation. Supportive measures may include gastric decontamination with activated charcoal soon after ingestion. ECG monitoring is essential due to the documented risk of severe cardiac arrhythmia.

When Urgent Medical Attention is Required

Call emergency services immediately if a suspected overdose victim has collapsed, experienced a seizure, is having trouble breathing, or cannot be awakened. Immediate medical evaluation is required for symptoms such as an irregular heartbeat, severe confusion, high fever, agitation, or loss of coordination, which may indicate Serotonin Syndrome or life-threatening cardiotoxicity.

Eligibility and Restrictions for Use

Citalopram (Cilodral) is officially approved for use only in adults aged 18 years and older. Regulatory bodies state that use in children and adolescents is not established and is not approved for the pediatric population.


The medicine is contraindicated and must not be used by patients currently taking Monoamine Oxidase Inhibitors (MAOIs), including Linezolid, or the antipsychotic medicine Pimozide, due to the risk of serious adverse events. It is also prohibited for individuals with a known hypersensitivity to Citalopram or its ingredients.

Population Restrictions and Conditional Use

Population Group Eligibility Restriction Regulatory Basis
Elderly patients (typically 60 years), hepatic impairment, or CYP2C19 Poor Metabolizers Maximum recommended dose is limited to 20 mg/day. Age, Metabolic, Organ Function
Cardiovascular Risk Not recommended for patients with certain cardiac conditions (e.g., congenital Long QT Syndrome, uncompensated heart failure) due to QTc prolongation risk. Comorbidity
Severe Renal Impairment Not studied; use requires caution and monitoring. Organ Function

For pregnancy and lactation, regulatory documentation advises that use is limited to when clinically warranted, and neonates exposed in the third trimester require observation for complications.

What should I know about interactions with other medicines?

Interactions with other medicines and products

Cilodral (citalopram) has officially documented interaction patterns that are classified based on the risk they pose for co-administration, as stated in regulatory prescribing information.

Formal Contraindications and Prohibitions

The most significant interaction restriction is the formal contraindication against co-administering citalopram with Monoamine Oxidase Inhibitors (MAOIs), including linezolid and intravenous methylene blue. This prohibition is due to the high risk of developing Serotonin Syndrome.

Co-administration with pimozide and other medicinal products that are known to prolong the QT interval is also strictly prohibited due to the potential for an additive cardiac effect.

Pharmacodynamic and Pharmacokinetic Interactions

Certain pharmacodynamic interactions increase the risk of serious complications. The co-administration of citalopram with other serotonergic medicinal products (e.g., triptans, tramadol, lithium) or the herbal product St. John’s Wort requires caution due to the risk of Serotonin Syndrome potentiation.

Citalopram may also increase the risk of bleeding events when taken with drugs that interfere with hemostasis, such as NSAIDs and warfarin.

From a pharmacokinetic perspective, regulatory data indicate that inhibitors of the CYP2C19 enzyme (e.g., omeprazole, cimetidine) may decrease citalopram clearance, leading to increased drug exposure. Furthermore, mandatory 14-day washout periods are required when switching between citalopram and an MAOI.

Mechanism of Action

Selective Inhibition of the Serotonin Transporter (SERT)

Citalopram is defined by its specific inhibitory action on the Serotonin Transporter (SERT) protein, which is primarily located on the presynaptic membrane of serotonergic neurons in the brain. By binding to SERT, Citalopram blocks the active reuptake of the neurotransmitter serotonin (5-HT) from the synaptic cleft back into the neuron. This molecular interaction is the essential first step in the drug's mechanism.

Augmenting Synaptic Serotonin Signaling

The inhibition of SERT leads to a rapid augmentation of serotonergic signaling throughout the brain's affective circuitry. This cascade involves the subsequent activation of postsynaptic 5-HT receptors and is sustained by the resulting high synaptic 5-HT levels. This mechanism is focused on neurotransmitter availability, distinguishing it from mechanisms that involve significant activity at multiple monoamine transporters and off-target receptors.

Systemic Adaptation and Affective Circuitry Modulation

The sustained serotonergic activity initiates adaptive changes within the system, including the desensitization of certain presynaptic autoreceptors. This systemic modulation influences the physiological systems that govern central regulatory responses. This mechanism influences the physiological processing of stimuli relevant to limbic system function, which shapes the drug's overall delayed but persistent physiological impact.

Dosage and Administration Information

Citalopram is administered orally once daily and is supplied as tablets (10 mg, 20 mg, 40 mg) and an oral solution. The tablets may be taken with or without food, allowing for flexible daily timing. The administration protocol follows established protocols concerning dosage, frequency, and duration.

Official Administration Guidelines

Category Official Instructions
Dosing Schedule (Adults) Treatment typically begins with 20 mg once daily. The maximum recommended daily dose for general adult use is 40 mg.
Dose Adjustment Any adjustment in dosage should be considered only after the patient has received the current dose for a minimum of one full week.
Population Maximums The maximum recommended dose is restricted to 20 mg once daily for older adults (aged 60 or 65 and over) and for individuals with hepatic impairment.
Oral Solution Preparation The bottle must be shaken well before use, and a calibrated measuring device is required for accurate dosing.
Missed Dose Rule If a dose is missed, the recommended procedure is to skip the missed dose and continue with the next scheduled dose at the usual time.

Course Structure Protocol

The use protocol defines an acute phase of treatment followed by a maintenance phase, which typically requires continuation for at least six months to sustain the response. This structured approach dictates a long-term treatment pattern. When concluding therapy, the dosage must be gradually reduced over a period of at least one to two weeks, as abrupt cessation is generally avoided.

Recent Clinical Evidence

Evidence for Acute Treatment and Relapse Prevention

Research exploring citalopram's role in Major Depressive Disorder (MDD) has involved numerous short-term, randomized controlled trials (RCTs). These studies observed adult patients over defined intervals, typically focusing on outcomes like symptom reduction and the rate of achieving a clinical response. Pooled analyses of this research describe patterns observed in the studies regarding measured symptom reduction when citalopram was compared to placebo. Long-term maintenance studies explored whether continuation treatment was associated with differences in the observation of a depressive episode returning (relapse or recurrence). These trials described patterns indicating differences in the measured time to recurrence compared to those who switched to placebo.

Research in Specific Patient Groups

Citalopram was evaluated in specific groups of older adults with depression, with some research describing similar patterns of change as seen in younger adults, while other small, short-term studies examined differences between the treatment and placebo in the population aged 75 and older. Research has also examined populations with comorbid conditions, but data for certain groups remain insufficient.

Study Limitations and Unclear Findings

Evidence for outcomes that extend beyond one year of continuous observation is limited, and long-term effects are not fully established. The consistency of remission rates (near-complete resolution of symptoms) is described as a key gap, as trial findings were mixed on this outcome. Furthermore, comparative evidence is lacking for certain long-term outcomes, and study results reflect group patterns, which does not determine whether an individual will respond similarly.
