Viagra

Viagra (sildenafil) is an anti-impotence medicine available by prescription intended for the treatment of erectile dysfunction in many of different age. It is supposed to be taken 40-60 minutes before having sex. Make sure you do not combine this medicine with alcohol or grapefruit juice to avoid interactions. Viagra is well tolerated and just a few side effects are possible, such as headache, sensitivity to light, diarrhea, changes in color vision, nosebleeds, insomnia, flushing, heartburn, and muscle aches. There is no need to tell your doctor about them unless they change in intensity and get bothersome. Before you ask your health care provider for a certain dose, make sure you mention the fact of ever being diagnosed with kidney disease, heart attack, coronary artery disease, blood cell disorder, history of a stroke, bleeding disorder, abnormal blood pressure, or stomach ulcer, as these medical conditions can affect the dose you are prescribed. Any other medications you have been prescribed are also supposed to be reported, including erythromycin, alpha-blocker medications, azole antifungals, other medications for impotence, mibefradil, high blood pressure medicines, cimetidine, rifamycins, and HIV protease inhibitors.
