Tadalafil and sildenafil are the two most widely prescribed treatments for erectile dysfunction. Both work well for most men, and both are sold as affordable generics. The question that matters is usually not which one is "better", but which one suits the way you live.
Generic sildenafil is typically taken about an hour before sex and lasts around four to five hours. A large meal can slow it down. Generic tadalafil, on the other hand, can work for up to 36 hours, and food has little effect. Some men also take a low daily dose of tadalafil so they do not have to plan ahead.
To compare the click here two in more detail, read the full guide here covers doses, timing and safety.
Safety first: 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. Seek medical help straight away 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 bring better results, 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 valid prescription is required for every order of a prescription medicine. More practical tips are in this article.
