What is Levitra?

Levitra is prescribed to treat impotence or erectile dysfunction (ED) in men. Levitra can help to relax muscles and increase the blood flow into the penis for men during sexual activity. This increase in blood flow may help men to achieve and maintain an erection.

Levitra may be used for purposes not listed in this medication guide.

 

Key Facts About Levitra

Levitra is a phosphodiesterase inhibitor, and it works by relaxing muscles and increasing blood flow into the penis.

You should not take Levitra more than one time in a 24 hour period.

If you are taking a nitrate drug for chest pain or heart problems you should not take Levitra. These medications include nitroglycerin (Nitrostat, Nitrolingual, Nitro-Dur, Nitro-Bid, and others), isosorbide dinitrate (Dilatrate-SR, Isordil, Sorbitrate), and isosorbide mononitrate (Imdur, ISMO, Monoket). Nitrates can also be found in some recreational drugs like amyl nitrate or nitrite (“poppers”). If you take Levitra and a nitrate drug you may experience a serious and sudden decrease in your blood pressure.

Levitra may decrease blood flow to the optic nerve of your eye, which may cause a sudden loss of vision. This rare occurrence has happened mostly in people who took Levitra and had heart disease, diabetes, high blood pressure, high cholesterol, were smokers, were over age 50, or had certain pre-existing eye conditions. We still do not know if Levitra caused the actual vision loss. If you experience sudden loss of your vision stop using Levitra right away and seek emergency medical attention.

While taking Levitra and during sexual activity, if you become dizzy or nauseated, or if you experience numbness, tingling or pain in your chest, arms, neck, or jaw, stop and call your doctor immediately. These signs could indicate that you are having a serious reaction to Levitra.

 

Before You Take Levitra

If you are allergic to vardenafil you should not take Levitra.

You should not take Levitra if you are taking nitrate medications. This includes nitroglycerin (Nitrostat, Nitrolingual, Nitro-Dur, Nitro-Bid, and others), isosorbide dinitrate (Dilatrate-SR, Isordil, Sorbitrate), and isosorbide mononitrate (Imdur, ISMO, Monoket).

If you take Levitra alongside nitrate medications you put yourself at risk of having a serious and sudden drop in blood pressure.

Tell your doctor if you have had either heart disease, a heart attack, a stroke, congestive heart failure or heart rhythm problems before taking Levitra.

Tell your doctor if you have high or low blood pressure, “Long QT Syndrome”, or coronary artery disease before taking Levitra.

Let your doctor know if you have retinitis pigmentosa, which is an inherited condition of the eye, before taking Levitra.

If you have a physical deformity of the penis, like Peyronie’s disease, or if you have previously been told that you should not have sexual intercourse for health reasons, you may not be a candidate to take Levitra.

You should inform your doctor if you have kidney or liver disease, are on dialysis or if you have a stomach ulcer.

If you have a blood disorder like sickle cell anemia, multiple myeloma, or leukemia, or a bleeding disorder like hemophilia you should tell your doctor before taking Levitra.

Grapefruit and grapefruit juice should not be consumed when you are taking Levitra, as it can interact with Levitra and potentially lead to dangerous side effects. Discuss your use of grapefruit products with your doctor.

You should not drink alcohol while taking Levitra as it may increase certain side effects of this medication.
