Sildenafil — what it is, how it works, and what to watch for
Sildenafil is the active ingredient in Viagra and its generics. It helps men get and keep an erection by boosting blood flow to the penis. It also treats pulmonary hypertension under a different brand and dose. If you’re reading about sildenafil because you or a partner needs it, this page gives clear, practical facts you can use right away.
Quick facts and how to use it
Most people take sildenafil 30–60 minutes before sex. Effects usually start within half an hour and can last up to four hours, though that varies by person. Typical doses for erectile dysfunction are 25 mg, 50 mg, or 100 mg—start low and adjust with your doctor. High-fat meals slow absorption, so taking it on a lighter stomach helps timing. Don’t take more than one dose in 24 hours.
Common side effects include headache, flushing, indigestion, nasal congestion, and light sensitivity. Rare but serious problems include sudden vision changes or a painful erection lasting more than four hours (priapism). If you get severe chest pain, fainting, or a sudden drop in vision, get emergency help.
Safety, interactions, and who should avoid it
Never mix sildenafil with nitrates (often prescribed for chest pain). That combo can cause a dangerous drop in blood pressure. Also be cautious with alpha-blockers, some antifungals, and HIV protease inhibitors—these can raise sildenafil levels and the risk of side effects. If you have severe heart disease, recent stroke or heart attack, very low blood pressure, or certain eye problems, your doctor may advise against sildenafil.
Talk to your prescriber about other medicines you take. Mention herbal supplements and recreational drugs too—those matter. If your erectile problems come on suddenly, follow up with a doctor to rule out underlying health issues like diabetes, high blood pressure, or depression.
Looking for alternatives? Tadalafil lasts much longer (up to 36 hours), while vardenafil works similarly to sildenafil. Lifestyle changes—exercise, weight loss, quitting smoking, and cutting back on alcohol—often improve erectile function and can reduce the need for drugs.
