Sildenafil and tadalafil are the two most widely prescribed treatments for erectile dysfunction. Both work well for most men, and both are sold as lower-cost generics. The real question is usually not which one is "better", but which one matches your plans.
Generic sildenafil is typically taken about an hour before sex and lasts around four to five hours. A high-fat meal can slow it down. Generic tadalafil, on the other hand, can work for up to 36 hours, and food makes little difference. Many men also take a low daily dose of tadalafil so they do not have to plan ahead.
For a side-by-side look, this practical guide explains the differences step by step.
A few safety points: never take either medicine with nitrate heart medicines or with "poppers". Tell your doctor about any other medicines you take. The usual side effects are headache, flushing, a blocked nose and indigestion. Get urgent help for an erection lasting more than four hours or any sudden loss of sight or hearing.
More is not always better. The licensed doses are 25, 50 or 100 mg for sildenafil and 2.5 to 20 mg for tadalafil. Bigger doses do not bring better results, but they do raise the risk of side effects. Only take the dose your prescriber has set.
