Viagra (sildenafil) is a medicine intended for the treatment of male impotence. A more specific term for this contrition is actually erectile dysfunction, or ED. ED can be caused by a variety of factors, but they can be divided into two groups psychological and physical. Make sure your health care provider knows that you are taking any of the following medications that may require your doctor to adjust your dosage: seizure medications, barbiturates, HIV protease inhibitors, efavirenz, rifampin, anticoagulants, rifabutin, other erectile dysfunction treatment drugs, antifungals, erythromycin, alpha blockers, beta blockers, cimetidine, amlodipine, high blood pressure medications, etc. People allergic to sildenafil or any other medicines of the kind are not supposed to start taking Viagra as they may experience an allergic reaction that may actually be more severe than before. You are also not supposed to take sildenafil with nitrate-based medications, allowing at least two weeks to pass between the two doses. While taking Viagra you need to keep in mind that this medicine will not cure your condition – it is just a very efficient treatment. However, if your erectile dysfunction was caused by psychological reasons taking this medicine is likely to restore your sexual ability, and if everything goes well you may not need to continue taking it every time you want to have sex. If you are a regular smoker, have a history of priapism or recently experienced dehydration your health care provider needs to be notified to make sure taking Viagra is safe for you.
