Drug Interactions

For pulmonary hypertension, sildenafil lowers blood pressure about one to two hours after a dose is taken. With a half-life of four hours, sildenafil and its active metabolite are completely cleared from the system in about 20 hours, though the effects fade before then. For erectile dysfunction, sildenafil produces its maximum effects for about two hours and can still produce an erectile response four hours after a dose is taken. For pulmonary hypertension, sildenafil’s benefits in lowering blood pressure were the same as a placebo (inert pill) after eight hours. For treatment of erectile dysfunction, take only one dose per day. SingleCare provides transparent drug pricing, so you can compare discounts at pharmacies near you.
