Clomipramine belongs to the class of antidepressant drugs known as the tricyclics. It is used mainly in the long-term treatment of depression.
Clomipramine is particularly useful in the treatment of obsessive and phobic disorders. In this case, the drug has to be taken for many months to achieve its full effect. It is also used to treat cataplexy (sudden loss of muscle tone) and narcolepsy (attacks of sleepiness).
Clomipramine has similar adverse effects to other tricyclic drugs, such as drowsiness, dizziness, dry mouth, and constipation. In overdose, clomipramine may cause coma and dangerously abnormal heart rhythms.
