Erection occurs naturally when a male is sexually excited or has sexual desire. The erection process is quick filling of the penis with more blood than usual. The penis tissues expand and the penis becomes hard or erected.

After the climax of sexual activity when orgasm is achieved, the extra blood flows out of the penis back into the body. The erection process naturally stops.

If an erection lasts for a long time (more than 4- 6 hours), it is not natural and is called priapism. This condition can permanently damage the penis. A person who experiences this condition should call a doctor immediately.  If a person ever has a prolonged erection that lasts more than 4 hours it should be carefully considered whether he could take Viagra.

Some health conditions and medications interfere with the natural erection process. There is not enough blood inflow in penis for maintaining good erections. The man who of cannot have erections face the problem called erectile dysfunction.

Sex is an activity which makes heart working harder and quicker. That is why sexual activity is not advisable sometimes for people who have heart problems. Before taking any drug for erectile dysfunction, ask your doctor if your heart is healthy enough to handle the extra strain of having sex.

A great number of clinical trials of Viagra were held to assess the ability of the drug to treat ED and its effectiveness. More than 3700 participants from different countries (aged 19– over 85 years) received Viagra during pre-marketing clinical trials. Over 550 participants were involved in studies for longer than one year.

In several placebo-controlled clinical studies, rate of side effects for Viagra was not significantly different from placebo .The side effects were mostly mild to moderate in nature.

In trials of all designs (including dose, age, health conditions) side effects in participants taking Viagra were generally similar.

In fixed-dose studies, the incidence of some side effects was related to increased dose.

The nature of the side effects in flexible-dose studies, which consider the recommended dosage administration, was similar to that for fixed-dose studies.

When the drug was taken as recommended in clinical trials, the following side effects were commonly reported:

• Headache;
• Flushing;
• Nasal congestion.

Such side effects as abnormal vision, rash, abdominal pain, allergic reaction, chest pain or respiratory tract infection occurred less than 2% of rate. Other side effects were so meaningless in rates that are not worth mentioning.

In fixed-dose studies abnormal vision (11%) was more common at 100 mg than at lower doses.
