Common Use
Clomipramine is a tricyclic antidepressant (TCA) used primarily as a first-line pharmacological treatment for obsessive-compulsive disorder (OCD). Among all antidepressants, clomipramine has the strongest evidence base for OCD treatment, making it a gold-standard option when obsessive thoughts and compulsive behaviors significantly impact daily life. Beyond its primary indication, clomipramine is also prescribed for major depression, panic disorder with or without agoraphobia, chronic pain syndromes (including neuropathic pain and fibromyalgia), anxiety disorders, phobias, and occasionally for cataplexy associated with narcolepsy. The medication works by potently inhibiting the reuptake of serotonin (and to a lesser extent norepinephrine) in the brain, thereby increasing the availability of these mood-regulating neurotransmitters at nerve synapses. This dual-action mechanism improves mood, reduces obsessive compulsive thoughts, lessens anxiety, and helps break the cycle of repetitive behaviors. Available under the brand name Anafranil and as an affordable Anafranil generic, clomipramine has been helping patients manage OCD and depression for decades.

Dosage and Direction
Clomipramine is taken orally, usually one to three times daily, with or without food. To minimize side effects and allow the body to adjust, treatment is typically started at a low dose (25 mg once daily) and gradually increased over several weeks to the therapeutic range, which commonly falls between 100 mg and 250 mg per day for OCD treatment. Your doctor will determine the optimal dosage based on your condition, response to therapy, and tolerability. For depression and anxiety, lower maintenance doses may be sufficient. Swallow tablets or capsules whole with a full glass of water. Do not stop taking clomipramine suddenly without consulting your doctor, as abrupt discontinuation can cause unpleasant withdrawal symptoms such as nausea, headache, irritability, sleep disturbances, and worsening of psychiatric symptoms. If a dose reduction is needed, your doctor will taper the medication gradually over several weeks.

Precautions
Before starting clomipramine, tell your doctor if you have a history of heart disease (including arrhythmias, heart block, or recent heart attack), seizure disorders, urinary retention or enlarged prostate, narrow-angle glaucoma, thyroid disorders, liver or kidney impairment, or bipolar disorder (as clomipramine may trigger manic episodes). This TCA can lower the seizure threshold, so extra caution is needed in patients with epilepsy or other risk factors for seizures. Avoid alcohol consumption during treatment, as combining alcohol with clomipramine significantly increases sedation and central nervous system depression. Limit activities requiring full alertness (such as driving or operating machinery) until you know how the medication affects you. Elderly patients are particularly sensitive to anticholinergic and sedative side effects, including dizziness, confusion, constipation, and falls. The FDA has issued a black-box warning about an increased risk of suicidal thoughts and behaviors in children, adolescents, and young adults taking antidepressants — close monitoring is essential during the first weeks of treatment and after any dose changes.

Contraindications
Do not use clomipramine if you are allergic to it or to other tricyclic antidepressants (such as imipramine, amitriptyline, or desipramine). Clomipramine is strictly contraindicated in patients who are currently taking or have recently taken (within 14 days) monoamine oxidase inhibitors (MAOIs), as the combination can cause a potentially fatal serotonin syndrome or hypertensive crisis. It should also be avoided in individuals who have had a recent myocardial infarction (heart attack), have severe heart rhythm disorders (bundle branch block, prolonged QT interval), or are in the acute recovery phase following cardiac events. Patients with uncontrolled narrow-angle glaucoma should not take clomipramine due to its anticholinergic effects. Co-administration with linezolid or intravenous methylene blue is also contraindicated.

Possible Side Effects
Common side effects of clomipramine include dry mouth, drowsiness and sedation, dizziness, constipation, nausea, increased sweating, tremor, blurred vision, weight gain, and sexual dysfunction (decreased libido, difficulty achieving orgasm). These anticholinergic and central nervous system effects are generally dose-dependent and often improve with continued use or dose adjustment. More serious side effects may include seizures (particularly at higher doses), irregular heartbeat or cardiac conduction changes (prolonged QT interval), orthostatic hypotension (sudden blood pressure drop upon standing), serotonin syndrome (when combined with serotonergic drugs — symptoms include agitation, high fever, rapid pulse, muscle rigidity, and confusion), or emergence of suicidal thoughts, especially in young adults. Blood disorders such as agranulocytosis or liver enzyme elevations occur rarely. Seek immediate medical attention if you experience chest pain, severe agitation, fainting, high fever, or signs of serotonin syndrome.

Drug Interaction
Clomipramine has significant interactions with multiple drug classes. MAO inhibitors are the most dangerous combination, potentially causing fatal serotonin syndrome or hypertensive crisis — a washout period of at least 14 days is required between discontinuing an MAOI and starting clomipramine, and vice versa. SSRIs (fluoxetine, fluvoxamine, paroxetine) and other serotonergic drugs increase the risk of serotonin syndrome and may also raise clomipramine blood levels through CYP enzyme inhibition. Anticholinergic drugs may intensify side effects such as dry mouth, constipation, urinary retention, and cognitive impairment. CNS depressants including benzodiazepines, opioids, and antihistamines amplify sedation. Drugs that affect heart rhythm (quinidine, procainamide, antiarrhythmics, certain antipsychotics) may increase the risk of dangerous cardiac conduction changes. CYP2D6 inhibitors (such as fluoxetine or bupropion) can significantly increase clomipramine plasma levels. Cimetidine may also raise clomipramine concentrations. Always inform your doctor about all medications, supplements, and herbal products you are taking.

Missed Dose
If you miss a dose of clomipramine, take it as soon as you remember. If it is close to the time of your next scheduled dose, skip the missed one and continue with your regular schedule. Do not double the dose to catch up, as this increases the risk of side effects including sedation and cardiac effects. Consistent daily dosing is important for maintaining therapeutic blood levels and optimal OCD treatment outcomes.

Overdose
Clomipramine overdose is a medical emergency and can be life-threatening. Overdose symptoms may include extreme drowsiness, confusion, agitation, hallucinations, rapid or irregular heartbeat, dangerously low blood pressure, respiratory depression, seizures, hyperthermia, or coma. Cardiac conduction abnormalities (widened QRS complex, prolonged QT interval) are among the most dangerous effects and may lead to fatal arrhythmias. Seek emergency medical help immediately if an overdose is suspected. Treatment involves cardiac monitoring, activated charcoal (if administered promptly), intravenous sodium bicarbonate for cardiac conduction abnormalities, seizure management with benzodiazepines, and intensive supportive care. Do not induce vomiting due to the risk of rapid deterioration and aspiration.

Storage
Store clomipramine at room temperature, between 20°C and 25°C (68°F to 77°F), away from heat, moisture, and direct light. Keep the medication in a tightly closed container and out of reach of children and pets, as accidental ingestion by children can be extremely dangerous. Do not store in the bathroom, where humidity can degrade the medication. Do not use after the expiration date printed on the packaging, and dispose of unused medication safely according to local pharmaceutical disposal guidelines.
