Viagra.

Viagra (sildenafil) is an anti-impotence drug that has been used for many years to treat erectile dysfunction – a disorder characterized by the inability of the male patient to get an erection hard enough to have sex. Viagra should not be used by females – it has been specially designed for the needs of men suffering from impotence. Your doctor will tell you if any medical conditions you have require a dose adjustment – so you will need to report them all, including antibiotics, antidepressants, enoxacin, HIV/AIDS medicines, antifungal medications, bosentan, conivaptan, diclofenac, imatinib, isoniazid, cimetidine, rifampin, as well as heart or blood pressure medications. To make sure you always benefit from your treatment tell your health care provider if you have any medical conditions that may require a dose adjustment – such as conditions affecting the shape of the penis, diabetes, chest pain, heart attack, blood cell problems, high or low blood pressure, heart, kidney, or liver disease, irregular heartbeat, stroke, blood circulation problems, high cholesterol, pulmonary veno-occlusive disease, bleeding disorder, or stomach ulcer.
