Description
What is Viagra?
Viagra (sildenafil) increases blood flow to specific parts of the body by relaxing the muscles in blood vessel walls.
Male impotence, or erectile dysfunction, is treated with Viagra. Revatio is a different brand of sildenafil that is used to treat pulmonary arterial hypertension and increase both men’s and women’s ability to exercise. Specific information about Viagra, not Revatio, is provided on this page.
Except as directed by your physician, do not take Revatio and Viagra at the same time.
Vital details
When taken with Viagra, certain medications may have unfavorable or harmful side effects. Inform your physician about all of the medications you are taking, particularly nitrates and riociguat (Adempas).
If you also take a nitrate medication for heart problems or chest pain (such as nitroglycerin, isosorbide dinitrate, isosorbide mononitrate, or some recreational drugs like “poppers”), avoid taking Viagra. When sildenafil is taken with a nitrate medication, there may be an abrupt and significant drop in blood pressure.
If your erection hurts or doesn’t go away after four hours, call your doctor or get emergency medical help. Penis damage can result from priapism, a prolonged erection.
If you experience sudden blindness, stop taking Viagra and get emergency medical attention.
