What is Viagra?

Important information

Some medicines can cause unwanted or dangerous effects when using Viagra. Tell your doctor about all your current medicines, especially riociguat (Adempas) and nitrates.

Do not take Viagra if you are also using any nitrate medication for chest pain or heart problems, including nitroglycerin, isosorbide dinitrate, isosorbide mononitrate, and certain recreational drugs such as poppers. Taking sildenafil with a nitrate medicine can cause a sudden and severe drop in blood pressure.

Contact your doctor or seek emergency medical help if your erection is painful or lasts longer than 4 hours. A prolonged erection (priapism) can damage the penis.

Stop using Viagra and get medical help if you suddenly have vision loss.
