We present a review comparing the use of tadalafil daily vs on-demand for erectile dysfunction. We examined randomized controlled trials and observational studies that examined the use of tadalafil for at least 8 weeks of follow-up with the primary outcome of International Index for Erectile Dysfunction-Erectile Function domain. Eight studies that examined the desired dosing regimens were identified. Of these, 6 studies included the primary end point of 12 weeks. Those patients taking tadalafil daily for 12 weeks scored on average 1.82 points higher in International Index for Erectile Dysfunction-Erectile Function domain scores, although the difference may not be clinically significant (Fig. 1).
