Viagra.

Viagra (sildenafil) can be prescribed if some male patient is unable to get a stable erection and needs to be taking some medicine that would make it possible to obtain and maintain an erection sufficient for penetration. This drug should be taken if your doctor says you will benefit from it. Any medical conditions must be reported, including pulmonary veno-occlusive disease, heart, kidney, or liver disease, diabetes, blood cell problems, bleeding disorder, heart attack, chest pain, stomach ulcer, high or low blood pressure, blood circulation problems, conditions affecting the shape of the penis, high cholesterol, irregular heartbeat, or a history of a stroke. You will need to keep n mind that some drugs you are using may cause interactions with Viagra. These may include HIV/AIDS medicines, diclofenac, conivaptan, isoniazid, imatinib, enoxacin, cimetidine, antidepressants, bosentan, antifungal medications, rifampin, antibiotics, and heart or blood pressure medications. Viagra will be efficient if you take it before having sex – this is not a cure for your impotence. Make sure you do not take Viagra more often than every 24 hours to avoid an overdose.
