Viagra belongs to a group of medicines called phosphodiesterase type 5 inhibitors.

Viagra will only help you to get an erection if you are sexually stimulated. You should not take viagra if you do not have erectile dysfunction. You should not take viagra if you are a woman.
Viagra is a treatment for men with erectile dysfunction, sometimes known as impotence. This is when a man cannot get, or keep a hard, erect penis suitable for sexual activity.
