What is vardenafil?
vardenafil relaxes muscles found in the walls of blood vessels and increases blood flow to particular areas of the body.

vardenafil is used to treat erectile dysfunction (impotence).

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

Important information

Taking vardenafil with certain other medicines can cause a sudden and serious decrease in blood pressure. Do not take vardenafil if you also take riociguat (Adempas) or a nitrate drug such as nitroglycerin.

SLIDESHOW

View Frightful (But Dead Serious) Drug Side Effects

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

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.

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.

Before taking this medicine

You should not use Vardenafil if you are allergic to vardenafil.

Taking Vardenafil with certain other medicines can cause a sudden and serious decrease in blood pressure. Do not take vardenafil if you also take riociguat (Adempas), or if you take a nitrate drug for chest pain or heart problems. Nitrates include nitroglycerin, isosorbide dinitrate, and isosorbide mononitrate. Nitrates are also found in some recreational drugs such as amyl nitrate or nitrite ('poppers').ers").uot;).

To make sure Vardenafil is safe for you, tell your doctor if you have:

• heart disease, heart rhythm problems;

• a recent history (in the past 6 months) of a heart attack, stroke, or congestive heart failure;

• a personal or family history of Long QT syndrome;

• high or low blood pressure;

• seizures;

• liver disease, kidney disease (or if you are on dialysis);

• a blood cell disorder such as sickle cell anemia, multiple myeloma, or leukemia;

• a bleeding disorder such as hemophilia;

• a stomach ulcer;

• hearing or vision problems, history of vision loss;

• an eye disorder such as retinitis pigmentosa (an inherited condition of the eye);

• a physical deformity of the penis (such as Peyronie's disease); or

• if you have been told you should not have sexual intercourse for health reasons.

vardenafil 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 Viagra or other drugs similar to vardenafil. Most of these people also had certain pre-existing eye problems or risk factors for blood vessel disorders (such as heart disease, diabetes, high blood pressure, high cholesterol, coronary artery disease, smoking, or being over 50 years old). It is not clear whether vardenafil is the actual cause of vision loss.

Although vardenafil is not for use in women, this medication is not expected to be harmful to an unborn baby.

Although vardenafil is not for use in women, it is not known whether this medicine passes into breast milk or if it could harm a nursing baby.

How should I take vardenafil?

Take vardenafil exactly as prescribed by your doctor. Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.

vardenafil can be taken with or without food.

vardenafil is usually taken only when needed, about 60 minutes before sexual activity. The medicine can help achieve an erection when sexual stimulation occurs. An erection will not occur just by taking a pill. Follow your doctor's instructions.

Do not take this medicine 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.
