How quickly do sildenafil and tadalafil start working?
Short answer
Sildenafil is often taken about one hour before sex. As-needed tadalafil is generally taken at least 30 minutes before sex. Results vary, and either medicine may take longer to work for some people. Sexual stimulation is needed. A heavy meal can delay sildenafil, while food has less effect on tadalafil.
Sildenafil is often taken about one hour before sex. Depending on your prescription, it may be taken from 30 minutes to 4 hours beforehand. As-needed tadalafil is generally taken at least 30 minutes before sex. Results vary, so these times are guides rather than promises.
A high-fat meal can delay how quickly sildenafil starts working. Tadalafil can be taken with or without food. Neither medicine works without sexual stimulation, and neither creates sexual desire. Stress, alcohol, and the cause of erectile dysfunction can also affect your experience. Results vary.
Daily tadalafil follows a different schedule. It is taken at about the same time each day rather than timed around sex. It takes several days to reach steady levels in the body. Follow your prescribed schedule instead of taking extra tablets before sex.
If treatment does not work as expected, do not take another dose early or add a second erectile dysfunction medicine. Ask your prescriber about timing, meals, and whether your treatment plan needs review.
