What is Viagra?

Viagra occurs when the human liver converts a natural substance called phosphodiesterase type 5 (PDE5) into its active ingredient within the penis. This results in an erection that is hard enough for sex. The active ingredient in Viagra is Sildenafil citrate, a medication used to treat erectile dysfunction.

Viagra may be taken with or without food. Viagra should not be taken more than once a day.

To get the most of Viagra, it is important to always consult your doctor or pharmacist. Sildenafil is not addictive.
