Onset defined as the earliest time to a successful erection (at least 1 erection in 4 attempts that led to successful intercourse). # In 2 studies, men were instructed to attempt intercourse at 24 or 36 hours after taking a single dose of GIOXIL-36. GIOXIL-36 was shown to improve, compared to placebo, the ability of men with ED to have a single, successful intercourse attempt at each of these time points. Multiple attempts after a single dose were not evaluated in these studies.
