Vardenafil

Why is this medication prescribed?

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).

How should this medicine be used?

Vardenafil comes as a 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. If you have certain health conditions or are taking certain medications, your doctor may tell you to take vardenafil less often. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take vardenafil exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Your doctor will probably start you on an average dose of vardenafil and increase or decrease your dose depending on your response to the medication. Tell your doctor if vardenafil is not working well or if you are experiencing side effects.

Other uses for this medicine

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
