Description
Unlike previously approved treatments for impotence, Viagra does not directly cause penis erection, but affects the response to sexual stimulation. The drug acts by enhancing smooth muscle relaxation using nitric oxide, a chemical that is normally released in response to sexual stimulation. This smooth muscle relaxation allows increased blood flow into certain areas of the penis, leading to an erection.
After a man takes Viagra, he must be sexually stimulated for it to work. This can include kissing or touching. Once a man takes Viagra and has sex, his erection will go away after intercourse, just like it would normally. Viagra works in as quickly as 30 minutes and lasts for about four hours.
Recommendations
Take Viagra Professional 20 to 40 minutes before you plan to have sex. If you take Viagra Professional after a high-fat meal (such as fish and chips, a cheeseburger or French fries), the medicine may take a little longer to start working.
Follow the directions on the label of this medicine or as directed by your doctor. Tell your doctor if Viagra does not help you get an erection (or does not last long enough). The dose may need adjustment in some cases.
Precautions
Most patients who are generally healthy and active can safely take Viagra but it is important to discuss with your doctor prior to taking it.
Viagra should not be taken by patients on nitrate-containing drugs; these are medications used in the treatment of angina.
Other conditions to be aware of when taking Viagra include: heart conditions (chest pain), high blood pressure, diabetes, kidney or liver problems, eye disease, anatomical deformation of the penis and blood disorders (haemophilia).
Alcohol, antihypertensives, ketoconazole, cimetidine and erythromycin all interfere with Viagra. You should avoid taking these drugs while taking Viagra.
