Viagra

Viagra (sildenafil) is a medication specially intended for patients who experience repeated problems with getting an erection hard enough to have sex. Such patients are unable to complete their sexual intercourse, as result of which their personal life and psychological health may be affected. Viagra has been reported to work in 80% of all cases helping patients even with most severe cases of impotence. Although depending on your age and health condition this medicine may be efficient during 4-5 hours, this time is usually sufficient to complete sexual intercourse. Viagra is preferred by most people in the world because this drug is highly efficient, has very few side effects and can be taken by people with certain health conditions that in some cases prevent them from other methods of treatment. Viagra should not be combined with erythromycin, nevirapine, high blood pressure medications, rifabutin, cimetidine, barbiturates, rifampin, beta blockers, efavirenz, anticoagulants, erectile dysfunction medicines, antifungals, seizure medications, HIV protease inhibitors, alpha blockers, and any herbal preparations, before your doctor tells you it's ok. Your health condition needs to be evaluated before your health care provider decides which dose you need to be taking. Such health conditions as pulmonary veno-occlusive disease, high or low blood pressure, conditions affecting the shape of the penis, heart, kidney, or liver disease, irregular heartbeat, bleeding disorder, chest pain, heart attack, stomach ulcer, blood circulation problems, high cholesterol, blood cell problems, diabetes, and a history of a stroke can be of importance in that case. Take Viagra exactly as recommended by your doctor.
