If you have untreated erectile dysfunction, you have probably heard about the wonder drug called Viagra, but you don’t feel brave enough to consult a doctor. Erectile dysfunction is such a common problem among men these days that there is really no reason to feel reticent about getting seeing a doctor.

Hopefully this article will give you the courage to tackle your problem head-on and get to your doctor as soon as possible. Viagra must be prescribed by your doctor – you cannot get it without a prescription.

Viagra works by preventing blood from flowing out of your penis. In fact, Viagra actually makes more blood get to your penis because it relaxes all the muscles and nerves in the penis. The penis needs to be full of blood before an erection is possible. Clinical studies have shown that 88 percent of men said they achieved good erections after using Viagra.

A dose of Viagra can last for as long as four hours. This may decrease in some men, especially men older than 65, and men who have certain diseases. It is very important to know that Viagra does not work on its own – you have to be sexually aroused for it to have any effect.

Viagra has a notable safety record and it can be used by men who suffer with a number of medical conditions such as diabetes, heart problems, or high blood pressure. In such cases however it is extremely important that a doctor monitors the patient regularly. Viagra is not addictive so you will not have to worry about getting hooked on it.

A word of warning: it is not advisable to drink alcohol with Viagra. Alcohol has a similar physiological action as Viagra – they both dilate the blood vessels. This may cause you to feel very dizzy and increase your heart rate, as well as lower your blood pressure – all of which could be dangerous.
