High blood pressure makes the heart work harder. This puts strain on the blood vessels, which then harden and narrow. This can prevent blood from getting to the penis and lead to ED.

VIAGRA was evaluated primarily at doses of 25 mg, 50 mg and 100 mg in 21 randomized, double-blind, placebo-controlled trials of up to 6 months in duration, using a variety of study designs (fixed dose, titration, parallel, crossover). Diary data indicated that on VIAGRA, 48% of intercourse attempts were successful versus 12% on placebo. Patients who demonstrate hemodynamic instability on alpha-blocker therapy alone are at increased risk of symptomatic hypotension with concomitant use of PDE5 inhibitors.

There were no reports of postural dizziness or orthostatic hypotension. For these four subjects, the placebo-subtracted mean maximum decreases from baseline in supine and standing systolic blood pressures were 14. REVATIO is used to treat a rare disease called pulmonary arterial hypertension (PAH). Safety of combined use of PDE5 inhibitors and alpha-blockers may be affected by other variables, including intravascular volume depletion and other anti-hypertensive drugs. Tell your healthcare provider if you have any side effect that bothers you or does not go away.
