Clomipramine Hydrochloride: Brands, Price & Uses in Bangladesh

Clomipramine Hydrochloride is a tricyclic antidepressant (TCA) with the following evidence-based uses:

Established/FDA-approved use

• Obsessive-Compulsive Disorder (OCD): Clomipramine Hydrochloride is indicated for the treatment of obsessions and compulsions in patients with OCD when these symptoms cause marked distress, are time-consuming, or significantly interfere with social or occupational functioning.

Guideline-supported / commonly used off-label uses

• Major depressive disorder (MDD): Clomipramine Hydrochloride is used off-label (and is an approved indication in some other countries) for depression, particularly when other antidepressants have failed, though it is not typically first-line due to its side-effect profile.
• Panic disorder with or without agoraphobia: used off-label in some treatment-resistant cases, based on limited trial evidence.
• Chronic pain / neuropathic pain syndromes: occasionally used off-label as an adjunct, consistent with other TCAs, though evidence is limited compared to amitriptyline.

Off-label uses should only be undertaken under specialist supervision after first-line options have been considered.

Obsessive-Compulsive Disorder (OCD)

Depression (off-label)

Typically initiated at 25 mg at bedtime, increased gradually as tolerated; usual maintenance range 100-150 mg/day, not to exceed 250 mg/day in adults. Elderly patients are generally kept to lower doses (commonly not exceeding 75 mg/day) due to increased sensitivity to anticholinergic and cardiac effects.

General administration notes

• Clomipramine Hydrochloride should be taken with food to reduce gastrointestinal upset.
• Dose should be titrated slowly under medical supervision; do not stop abruptly (see Precautions).
• Full therapeutic benefit for OCD/depression may take 2-4 weeks or longer.
• Renal/hepatic impairment: use with caution and at lower doses, with close monitoring; well-established formal dose adjustment guidelines are not established, so dosing should be individualized by the treating physician.

Side effects associated with Clomipramine Hydrochloride are generally consistent with the tricyclic antidepressant class and are often dose-related.

Very common (reported in a large proportion of patients)

• Dry mouth, constipation, and other anticholinergic effects
• Somnolence/drowsiness and fatigue
• Tremor and dizziness
• Nausea, dyspepsia, and weight gain
• Sexual dysfunction (notably ejaculatory failure in men, decreased libido)
• Excessive sweating

Less common but clinically important

• Orthostatic hypotension and tachycardia
• Blurred vision, urinary retention/hesitancy
• Weight gain, hyponatremia (particularly in elderly patients)

Serious (require prompt medical attention)

• Seizures, particularly at higher doses or with rapid dose increases
• Cardiac conduction abnormalities and arrhythmias
• Suicidal thinking or behavior, especially in patients under 25 years of age (see Precautions)
• Angle-closure glaucoma (acute eye pain, vision changes)
• Serotonin syndrome (when combined with other serotonergic agents)
• Rare severe skin reactions (e.g., DRESS syndrome)
