Viagra works by increasing blood flow to the penis. This is done by blocking an enzyme called phosphodiesterase type 5 (PDE5). PDE5 breaks down a chemical called cyclic guanosine monophosphate (cGMP), which is responsible for relaxing the muscles in the blood vessels of the penis. When PDE5 is blocked, cGMP can build up, which causes the blood vessels in the penis to relax and widen. This allows more blood to flow into the penis, which results in an erection.
Viagra only works if a man is sexually aroused. If a man is not aroused, Viagra will not cause an erection.
Viagra is available as a tablet that is taken by mouth. It should be taken about an hour before sexual activity, but it can be taken 30 minutes to 4 hours beforehand. Viagra is available in three strengths: 25 milligrams (mg), 50 mg, and 100 mg. The starting dose is usually 50 mg, but your doctor may prescribe a lower or higher dose depending on your individual needs.
Viagra is generally safe for most men to take. However, it can cause some side effects, such as headache, flushing, upset stomach, and blurred vision. These side effects are usually mild and go away on their own. In rare cases, Viagra can cause more serious side effects, such as heart attack, stroke, and sudden hearing loss.
