Information

Various medications and recreational drugs can have an effect on sexual arousal and sexual performance. What causes impotence in one man may not affect another man.

If you think that a medication you are taking is having a negative effect on your sexual performance, discuss the matter with your health care provider. Never stop taking any medication without first consulting your health care provider, because some medications can produce life-threatening reactions if they are not carefully and slowly stopped or switched appropriately.
