Another brand of sildenafil is Revatio, which is used to treat pulmonary arterial hypertension and improve exercise capacity in men and women. However, this page contains specific information for Viagra, not Revatio. It is advised not to take Viagra while also taking Revatio, unless your doctor tells you to. Some medicines can cause unwanted or dangerous effects when used with Viagra. It is important to tell your doctor about all your current medicines, especially riociguat (Adempas) and nitrates. Do not take Viagra if you are also using a nitrate drug for chest pain or heart problems, including nitroglycerin, isosorbide dinitrate, isosorbide mononitrate, and some recreational drugs such as “poppers”. Taking sildenafil with a nitrate medicine can cause a sudden and serious decrease in blood pressure. Contact your doctor or seek emergency medical attention if your erection is painful or lasts longer than 4 hours. A prolonged erection (priapism) can damage the penis. Stop using Viagra and get emergency medical help if you have sudden vision loss. Before taking this medicine, you should not use Viagra if you are allergic to sildenafil, or if you take other medicines to treat pulmonary arterial hypertension, such as riociguat (Adempas). If you take nitrates, do not take Viagra. This includes nitroglycerin, isosorbide dinitrate, and isosorbide mononitrate. Nitrates are also found in some recreational drugs such as amyl nitrate or nitrite (“poppers”). Taking sildenafil with a nitrate medicine can cause a sudden and serious decrease in blood pressure. To make sure Viagra is safe for you, tell your doctor if you have ever had heart disease or heart rhythm problems, coronary artery disease, a heart attack, stroke, or congestive heart failure, high or low blood pressure, liver or kidney disease, a blood cell disorder such as sickle cell anemia, multiple myeloma, or leukemia, a bleeding disorder such as hemophilia, a stomach ulcer, retinitis pigmentosa (an inherited condition of the eye), a physical deformity of the penis (such as Peyronie’s disease), or if you have been told you should not have sexual intercourse for health reasons. Viagra can decrease blood flow to the optic nerve of the eye, causing sudden vision loss. This has occurred in a small number of people taking sildenafil, most of whom also had heart disease, diabetes, high blood pressure, high cholesterol, or certain pre-existing eye problems, and in those who smoked or were over 50 years old. In conclusion, Viagra is a powerful drug that can help many men with erectile dysfunction, but it is important to use it safely and under the guidance of a healthcare professional.
