Choosing Between Sildenafil and Tadalafil

Tadalafil and sildenafil are the two most widely prescribed treatments for erectile dysfunction. Both help most men who try them, and both are now available as cheaper generics. The question that matters is often not which one is "better", but which one fits your routine.

Sildenafil is normally taken about an hour before sex and works for four to five hours. A large meal can slow it down. Generic tadalafil, on the other hand, can last for up to 36 hours, and food has little effect. Many men also take a low daily dose of tadalafil so they do not have to plan ahead.

To compare the two in more detail, this practical guide explains the differences step by step.

Safety first: generic cialis never take either medicine with nitrate tablets or sprays for chest pain or with "poppers". Tell your doctor about any blood pressure tablets. Common 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.

Strength matters too. 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. Stick to the dose on your prescription.

When you buy generic ED tablets online, make sure the strength matches your prescription and keep the leaflet. A valid prescription is required for every order of a prescription medicine. There is more detail on this page.
