What is the most important information I should know about Cialis?

• Do not take Cialis 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 Cialis with a nitrate medicine can cause a serious decrease in blood pressure, leading to fainting, stroke, or heart attack.
• If you become dizzy or nauseated, or have pain, numbness, or tingling in your chest, arms, neck, or jaw during sexual activity, stop and call your doctor right away. You could be having a serious side effect of Cialis.
• Do not take Cialis 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.
• A small number of patients have had a sudden loss of eyesight after taking Cialis. This type of vision loss is caused by decreased blood flow to the optic nerve of the eye. It is not clear whether Cialis is the actual cause of such vision loss. Sudden vision loss with Cialis use has occurred most often in people with 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.
• Stop using Cialis and get emergency medical help if you have sudden vision loss.
