What Is Viagra?

Viagra is a film-coated tablet that treats erectile dysfunction (ED) in adult men. It contains sildenafil, a type of medicine called a phosphodiesterase type 5 (PDE5) inhibitor. By relaxing blood vessels in the penis, Viagra helps improve blood flow during sexual arousal—making it easier to get and keep an erection.

What Is Viagra Used For?

Viagra is used to treat erection problems such as:

— Difficulty getting or maintaining an erection
— Erections that aren’t firm enough for sex
— Reduced sexual performance due to poor blood flow

It’s for men who have ED and need help achieving or sustaining an erection.

How Does Viagra Work?

Sildenafil, the active ingredient in Viagra, works by widening the blood vessels in the penis. This improves circulation and allows more blood to flow in when you’re sexually stimulated. It won’t cause an automatic erection—you still need arousal for it to take effect.

How Should It Be Taken?

To get the best results, follow these directions:

— Take 1 tablet about an hour before sexual activity
— Swallow whole with water, with or without food
— Avoid taking more than 1 tablet in 24 hours
— A heavy meal may delay the effects
— Only take Viagra when you plan to have sex

Viagra works for most men within 30 to 60 minutes, but it may take longer depending on what you’ve eaten. If it doesn’t work the first time, try again—sometimes it takes a few attempts.
