There are many drugs which may potentially induce erectile dysfunction.

Various medications and illegal drugs can have a great impact on sexual ability of a man and his sexual performance. Still some men are more vulnerable or sensitive to the side effects of the different medications, others have no or minor sexual side effects.

If you suspect that a medication you regularly use has a negative effect on your sexual performance, discuss it with your medical professional.
