A Plain Guide to Generic ED Tablets

Tadalafil and sildenafil are the two most widely prescribed treatments for erectile dysfunction. Both have a long track record, and both are now available as cheaper generics. The main question is usually not which one is "better", but which one fits your routine.

Sildenafil is usually taken about an hour before sex and works for four to five hours. A large meal can delay the effect. Tadalafil, on the other hand, can work for up to 36 hours, and food makes little difference. Some men also take a low daily dose of tadalafil so they never need to time a tablet.

For a side-by-side look, this practical guide covers doses, timing and safety.

Safety first: never take either medicine with nitrate tablets or sprays for chest pain or with "poppers". Tell your doctor about any blood pressure tablets. The usual side effects are headache, flushing, a blocked nose and indigestion. Get urgent help for an erection lasting more than four hours or sudden changes in vision.

Do not chase higher strengths. The licensed doses are 25, 50 or 100 mg for sildenafil and 2.5 to 20 mg for tadalafil. Bigger doses do not reliably work better, but they do raise the risk of side effects. Only take the dose your prescriber has set.

If you choose to buy generic sildenafil or tadalafil online, make sure the strength matches your prescription and read the patient leaflet. A ed meds online valid prescription is required for every order of a prescription medicine. There is more detail on this page.
