Availability and Usage

Viagra is currently available for use as a pill that can be taken orally. At some point a Viagra cream may also be available, but is not currently yet.

The pill you take is easiest swallowed with a glass of water. It works best if you eat a lower fat meal than a higher fat one, or if you just take it on a empty stomach.

Usually it works best for people who take it at least an hour before intercourse. It should start working in less time than that though-often in only a half an hour.

However, a typical erection will last for about thee to four hours. Therefore, you could take it far enough in advance in case you don’t have time to take it closer to the time when you will have sex.
