Important information about naprosyn 500

Do not take naprosyn 500 if you are also using a nitrate drug for chest pain or heart problems. This includes nitroglycerin (Nitrostat, Nitrolingual, Nitro-Dur, Nitro-Bid, and others), isosorbide dinitrate (Dilatrate-SR, Isordil, Sorbitrate), and isosorbide mononitrate (Imdur, ISMO, Monoket). Nitrates are also found in some recreational drugs such as amyl nitrate or nitrite ("poppers"). Taking naprosyn 500 with a nitrate medicine can cause a serious decrease in blood pressure, leading to fainting, stroke, or heart attack. During sexual activity, if you become dizzy or nauseated, or have pain, numbness, or tingling in your chest, arms, neck, or jaw, stop and call your doctor right away. You could be having a serious side effect of naprosyn 500.

Do not take naprosyn 500 more than once a day. Allow 24 hours to pass between doses. 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.

naprosyn 500 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 naprosyn 500, most of whom also had heart disease, diabetes, high blood pressure, high cholesterol, or certain pre-existing eye problems, and in those who smoke or are over 50 years old. It is not clear whether naprosyn 500 is the actual cause of vision loss.

Stop using naprosyn 500 and get emergency medical help if you have sudden vision loss.
