Generic name: Vardenafil
Vardenafil is used to treat erectile dysfunction (impotence) in men age 18 years or older. Vardenafil increases the body's ability to achieve and maintain an erection during sexual stimulation.
Vardenafil does not directly cause an erection of the penis, but it alters the body’s response to sexual stimulation by enhancing the effect of the nitric oxide, a chemical that is normally released during stimulation. Nitric oxide causes relaxation of the muscles in the penis, which allows for better blood flow to the penile area. This medication does not cure impotency, increase a man’s sexual desire, protect from sexually transmitted diseases, or serve as birth control. It only helps maintain an erection when a man is sexually excited.
