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

•

A small number of patients have lost eyesight in one eye after taking vardenafil. 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 vardenafil 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 vardenafil if you have any loss in your eyesight and seek medical help right away.

•

Do not take vardenafil if you are taking any of the following medicines:

a nitrate such as nitroglycerin (Nitrostat, Nitrolingual, Nitro-Dur, Nitro-Bid, Minitran, Deponit, Transderm-Nitro, others), isosorbide dinitrate (Dilatrate-SR, Isordil, Sorbitrate), isosorbide mononitrate (Imdur, ISMO, Monoket), and others;

a recreational drug such as amyl nitrate or nitrite ("poppers"); or

an alpha blocker such as doxazosin (Cardura), guanadrel (Hylorel), prazosin (Minipress), terazosin (Hytrin), alfuzosin (Uroxatral), tamsulosin (Flomax), and others.

•

Taking vardenafil with any of these medications may cause very low blood pressure, possibly resulting in dizziness, fainting, stroke, or heart attack

•

Contact your doctor or seek emergency medical attention for any erection that lasts longer than 4 hours. A sustained erection can damage the penis.

•

Refrain from further sexual activity and notify your doctor it you develop dizziness, nausea, or angina (pain, tightness, discomfort, numbness, or tingling in the chest, arms, neck, or jaw) during sexual activity.

•

Do not take vardenafil more than once a day. In some cases, use of vardenafil may be restricted to once every 72 hours (3 days). Follow your doctor's instructions.
