Clomipramine is a tricyclic antidepressant used to treat obsessive-compulsive disorder (OCD), phobic states, and depression (when sedation is helpful). It is often prescribed when obsessive thoughts, intense fears, or depressed mood interfere with daily life.

Some people may notice early improvements in a few weeks, but meaningful benefit for OCD or depression often takes 6–12 weeks, and full effects can take longer. Steady drug levels may take 1–3 weeks after dose changes. Continue taking it for as long as prescribed and do not stop it suddenly.

Take it exactly as your doctor prescribes. Treatment usually starts at a low dose and is increased gradually to reduce side effects. Take doses with meals if advised; this will help reduce upset stomach. Take it at the same time each day and ensure to attend all follow-up visits so your doctor can review your dose and response.

Yes. Clomipramine may cause seizures, heart rhythm problems, and can increase suicidal thoughts in young people early in treatment. Do not use it with MAO inhibitors or within 14 days of stopping them due to the risk of life-threatening serotonin syndrome. Get urgent help for new suicidal thoughts, fainting, chest pain, severe heartbeat changes, or signs of serotonin syndrome like high fever, stiff muscles, or confusion.
