Sexual side-effects of clomipramine (Anafranil).

An attempt was made to measure the effects of depressive illness and of clomipramine (Anafranil) therapy in doses of 30 mg and 75 mg daily on sexual appetite and performance. A special questionnaire was devised to gather information on sexual habits before illness, during illness and following treatment. It proved difficult to differentiate between the beneficial effects of recovery from depression and the possible adverse drug effects on sexual activity. Two patients dropped out of the study because of supposed sexual side-effects--a male with ejaculatory difficulties and a female with orgasmic impotence. Fifty-four patients completed the sexual questionnaire and a four-week course of clomipramine. There were nineteen males and thirty-five females. Sixty-eight per cent of males and 57% of females had their 'sex life' impaired by depressive illness. Coital rate was decreased and depression interfered with performance and satisfaction. Clomipramine therapy seemed to have advantageous and disadvantageous effects. The advantageous effects were probably associated with improvement in depressive illness. There was evidence that clomipramine had an adverse effect sexually in 26% of males and 14% of females. The effect was dose-related in females.
