Viagra

Viagra (sildenafil) is a popularly prescribed drug that helps to keep impotence under control, providing each patient taking it for up to 5 hours of efficiency. To make sure this medicine works properly for you, never exceed the dose you are prescribed to avoid the following symptoms of an overdose: chest pain, lightheadedness, fainting, nausea, and irregular heartbeat. Viagra comes in three different doses – containing 25, 50 and 100 mg of the active ingredient. The initial dose prescribed can depend on a number of factors, including your age, severity of your impotence and some health conditions you have ever been diagnosed with. The following health conditions are especially important to mention when talking to your doctor: irregular heartbeat, stomach ulcer, bleeding disorder, diabetes, high cholesterol, stroke, blood circulation problems, high or low blood pressure, a history of a heart attack, heart, kidney, or liver disease, and any other conditions that cause concern. If you are taking antifungals, heart or blood pressure medications, rifampin, antidepressants, cimetidine, diclofenac, bosentan, isoniazid, HIV/AIDS medicine, or any antibiotics, discuss with your doctor the possibility of combining these meds with Viagra and whether you will be able to have your dose increased if you do not feel any benefits of the treatment.
