It is taken orally, usually about an hour before sexual activity, and can be effective for up to four hours. While Viagra has been shown to be effective for many men, it does come with some potential side effects. These can include headaches, flushing, indigestion, and nasal congestion.

This enzyme breaks down cGMP, a substance that induces smooth muscles to relax. Blocking PDE-5 means increased levels of cGMP within the smooth muscles which promotes muscle relaxation and vasodilation (a widening of blood vessels). • High levels of PDE-5 are found in the penis, lungs, and retina. PDE-5 is also found throughout the body within the smooth muscle cells of the blood vessels and muscles. • Sildenafil belongs to the class of medicines known as selective phosphodiesterase (PDE) type 5 inhibitors. 2.

How Much Viagra Should I Take the First Time? The usual first-time dose of Sildenafil, the active ingredient in Viagra, is one 50mg tablet, which is taken with a glass of water an hour before the time you’re planning to have sex.
