Sildenafil and tadalafil are the two most common treatments for erectile dysfunction. Both help most men who try them, and both are sold as cheaper generics. The question that matters is usually not which one is "better", but which one fits your routine.
Sildenafil is typically taken about an hour before sex and lasts around four to five hours. A large meal can delay the effect. Tadalafil, on the other hand, can last click here 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: never take either medicine with nitrate tablets or sprays for chest pain or with "poppers". Tell your doctor about any other medicines you take. 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.
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.
When you buy medicine online, check the strength on the pack and keep the leaflet. A valid prescription is required for every order of a prescription medicine. More practical tips are in this tadalafil and sildenafil guide.
