Usually it takes effect after about thirty minutes from the time sildenafil citrate is introduced into the body. In healthy persons, getting an erection after being sexually stimulated is normal, but with those who experience erectile dysfunction, having an erection is especially difficult.

However, having to plan sexual intercourse beforehand and delaying it until an erection is achieve can adversely affect romantic spontaneity and reduce sexual excitement. Within a period of at least four hours, sildenafil citrate stays in the bloodstream and afterwards it is washed out of the blood through the liver and the kidneys.
