Sildenafil and tadalafil are the two most widely prescribed treatments for erectile dysfunction. Both work well for most men, and both are now available as lower-cost generics. The main question is usually not which one is "better", but which one matches your plans.
Sildenafil is typically taken about an hour before sex and lasts around four to five hours. A heavy meal can delay the effect. Generic tadalafil, on the other hand, can last for up to 36 hours, and food makes little difference. Plenty of men also take a low daily dose of tadalafil so they do not have to plan ahead.
For a side-by-side look, read the full guide here explains the differences step by step.
Before you start: never take either medicine with nitrate heart medicines or with "poppers". Let your doctor know about any alpha-blockers. The usual side effects are headache, flushing, a blocked nose and indigestion. Seek medical help straight away for an erection lasting more than four hours or sudden changes in vision.
More is not always better. The licensed doses are 25, 50 or 100 mg for sildenafil and 2.5 to 20 mg for tadalafil. Higher-strength tablets do not bring better results, but they do raise the risk of side effects. Stick to the dose on your prescription.
