Doctor if i take viagra (sildenafil) and if my erection last more than 4hours what can i do to stop it?
A doctor has provided 1 answer
Dangerous: Erections lasting more than 2-3 hrs are dangerous for potential for permanent tissue damage. Drinking a lot of fluids and using a smaller dose of viagra (sildenafil) would help if you have to use it.
