What is the most important information I should know about Viagra?
� A small number of patients have lost eyesight in one eye after taking Viagra. This type of vision loss is called non-arteritic anterior ischemic optic neuropathy (NAION). NAION causes a sudden loss of eyesight because blood flow is blocked to the optic nerve. It is not clear at this time if Viagra causes NAION. NAION also happens in patients who do not take this medicine. People who have a higher chance for NAION include those who:
� have heart disease;
� are over 50 years old;
� have diabetes;
� have high blood pressure;
� have high cholesterol;
� smoke; or
� have certain eye problems.
� Stop using Viagra if you have any loss in your eyesight and seek medical help right away.

Nitrates include nitroglycerin (Nitrostat, Nitrolingual, Nitro-Dur, Nitro-Bid, Minitran, Deponit, Transderm-Nitro, 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\”).
