Drugs that may cause impotence

Alternative names

Various medications and recreational drugs can have an affect on sexual arousal and sexual performance. It should be noted that what causes impotency in one man may cause an erection in another.

If you suspect that a medication you are taking is having a negative effect on sexual performance, discuss the matter with your health care provider.
