Viagra.

Viagra (sildenafil) is usually recommended for males diagnosed with impotence, or erectile dysfunction, the latter being a more precise term for the condition. It's important that you talk to your doctor about your treatment in advance to make sure you will benefit from taking Viagra as mush as possible. You will need to tell your health care provider about any of the following medications you are using at the moment and that can potentially interact with the effects of Viagra: certain antifungals, rifabutin, erythromycin, efavirenz, anticoagulants, other erectile dysfunction meds, bosentan, barbiturates, HIV protease inhibitors, nevirapine, medications for high blood pressure, cimetidine, amlodipine, rifampin, beta blockers, seizure medications, and some alpha blockers. If you are not sure how what the medicine you are using is called – be sure to contact your health care provider or pharmacist and ask about it. Mild side effects of Viagra are possible although don't tend to last for too long. They may include headache, upset stomach, memory problems, stuffy nose, back pain, warmth or redness in your face or chest, and some other ones that can be quite individual.
