Vardenafil is used to treat erectile dysfunction (impotence; inability to get or keep an erection) in men. Vardenafil is in a class of medications called phosphodiesterase (PDE) inhibitors. It works by increasing blood flow to the penis during sexual stimulation. Vardenafil does not cure erectile dysfunction or increase sexual desire. Vardenafil does not prevent pregnancy or the spread of sexually transmitted diseases such as human immunodeficiency virus (HIV). Vardenafil comes as a tablet and a rapidly disintegrating (dissolves in the mouth and is swallowed without water) tablet to take by mouth. It is usually taken as needed, with or without food, 60 minutes before sexual activity. Vardenafil usually should not be taken more often than once every 24 hours.

After the man is done having sex, this extra blood flows out of the penis back into the body.

You should call a doctor immediately if you ever have a prolonged erection that lasts more than 4 hours. Therefore sexual activity may not be advisable for people who have heart problems. Before you start any treatment for erectile dysfunction, ask your doctor if your heart is healthy enough to handle the extra strain of having sex. If you have chest pains, dizziness or nausea during sex, stop having sex and immediately tell your doctor you have had this problem.
