Description

What is Viagra?

Viagra relaxes muscles found in the walls of blood vessels and increases blood flow to particular areas of the body.

Viagra is used to treat erectile dysfunction (impotence) in men. Another brand of sildenafil is Revatio, which is used to treat pulmonary arterial hypertension and improve exercise capacity in men and women. This page contains specific information for Viagra, not Revatio.

Do not take Viagra while also taking Revatio, unless your doctor tells you to.

Warnings

Some medicines can cause unwanted or dangerous effects when used with Viagra. Tell your doctor about all your current medicines, especially riociguat (Adempas) and nitrates.
