Dietary effects

Sildenafil, the active ingredient, is absorbed from the intestines and works by circulating blood in the body.

If you have a meal, wait about 2 hours after eating before taking it.

The effects of alcohol 

A small amount of alcohol is fine, but excessive alcohol intake slows brain function and neurotransmission and reduces male function.
