There is a potential for cardiac risk of sexual activity inpatients with preexisting cardiovascular disease. Therefore, treatments for erectile dysfunction, including VIAGRA, should not be generally used in men forwhom sexual activity is inadvisable because of their underlying cardiovascular status.

The maximum recommended dose of 100 mg sildenafil was not evaluated in this study [see DRUG INTERACTIONS]. In the third study, a single oral dose of VIAGRA 100 mg or matching placebo was administered in a 3-period crossover design to 20 generally healthy males with BPH. In dose period 1, subjects were administered open-label doxazosin and a single dose of VIAGRA 50 mg simultaneously, after at least 14 consecutive days of doxazosin. If a subject did not successfully complete this first dosing period, he was discontinued from the study. Subjects who had successfully completed the previous doxazosin interaction study (using VIAGRA 50 mg), including no significant hemodynamic adverse events, were allowed to skip dose period 1. Treatment with doxazosin continued for at least 7 days after dose period 1.

An interaction is when a substance changes the way a drug works. If these effects are mild, they may go away within a few days or a couple of weeks.

A causal relationship between VIAGRA andthese events has not been established. In humans, VIAGRA has no effect onbleeding time when taken alone or with aspirin.
