Most, but not all, of these patients had preexisting cardiovascular risk factors. Many of these events were reported to occur during or shortly after sexual activity, and a few were reported to occur shortly after the use of Cialis without sexual activity. Others were reported to have occurred hours to days after the use of Cialis and sexual activity. It is not possible to determine whether these events are related directly to Cialis, to sexual activity, to the patient's underlying cardiovascular disease, to a combination of these factors, or to other factors [see Warnings and Precautions (5.1)].

Viagra, commonly referred to as the "little blue pill" was the first erectile dysfunction medication to be approved by the U.S. Food and Drug Administration (FDA). By inhibiting phosphodiesterase, Viagra enhances the effect of nitric oxide allowing for smooth muscle relaxation and increasing blood flow to specific areas of the body in the presence of sexual arousal or stimulation. Viagra exhibits no therapeutic responses in the absence of sexual stimulation.
