Viagra™

Viagra™ (sildenafil citrate) improves a man's natural response to sexual stimulation. To understand how, you need to understand how an erection happens in the first place.

Erections are all about increasing blood flow to the penis. Without sexual stimulation, the body limits blood flow into the penis. This keeps the penis flacid (soft, or not erect).

When a man is sexually aroused, the arteries in the penis relax and widen, allowing more blood to flow into the penis. As the penis expands and hardens, veins that normally carry blood away from the penis become compressed. This restricts how much blood can flow out of the penis. With more blood flowing in and less flowing out, the penis enlarges to the maximum, resulting in an erection.

If the nerves or blood vessels associated with this process aren't working properly, a man may not be able to get an erection.

Viagra increases blood flow to the penis, so that when a man is sexually aroused, he can have an erection. When the sexual encounter is over, his erection goes away.

If a man takes Viagra (sildenafil citrate) and then circumstances change and he isn't sexually stimulated, he won't get an erection. You won't get an erection just by taking the pill.

Viagra is not a hormone.
Viagra is not an aphrodisiac.
It is a prescription that improves the erectile function of men with erection problems.

Viagra (sildenafil citrate) was well tolerated in clinical trials. Some men experienced side effects, including headaches, facial flushing, and upset stomach. These were generally mild to moderate in nature and went away in a short period of time. A small percentage of men (3%) reported mild and temporary visual effects, including color tinge, increased sensitivity to light, or blurred vision. Side effects generally have not caused patients to stop taking Viagra.

Viagra is not for everyone. Viagra should not be taken by patientswho use drugs known as nitrates, in any form, at any time. One of the most commonly used nitrates is nitroglycerin, which is frequently prescribed for angina (chest pain due to heart disease). Nitrates can lower blood pressure ti unsafe levels if used with Viagra. It is important to tell your doctor about any medications you take.

Remember that the use of Viagra offers no protection against sexually transmitted diseases (including HIV-the virus that causes AIDS).

Because sexual activity can be demanding on the heart, you may want to talk to your doctor about your cardiovascular health before using Viagra.

What to expect when you take Viagra.

Viagra was found to be highly effective in tests with men who had ED-about three out of four of the men reported improved erections (compared to one out of four who used a placebo). Patients reported that about two out of three of their attempts to have sexual intercourse were successful with Viagra (compared to one out of five attempts for patients on placebo). If Viagra doesn't produce the same results for you, don't be discouraged.

You will need to learn how Viagra works for you through personal experience. Viagra tablets come in three dosage strengths: 25 mg, 50 mg, and 100 mg. If you don't get the results you expect the first few times you use Viagra, call your doctor. Together you can determine the dosage that allows you to respond to sexual stimulation and with which you are comfortable. And remember, no more than one Viagra a day.
