What is vardenafil?

Vardenafil relaxes muscles of the 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

Some medicines can cause unwanted or dangerous effects when used with vardenafil. Tell your doctor about all your medicines, especially riociguat (Adempas).

Do not take vardenafil if you are also using a nitrate drug for chest pain or heart problems, including nitroglycerin, isosorbide dinitrate, isosorbide mononitrate, and some recreational drugs such as "poppers". Taking vardenafil with a nitrate medicine can cause a sudden and serious decrease in blood pressure.

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.

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

Before taking this medicine

You should not use vardenafil if you are allergic to it, or if you take other medicines to treat pulmonary arterial hypertension, such as riociguat (Adempas).

Vardenafil is not approved for men younger than 18 years old.

Do not take vardenafil if you are also using a nitrate drug for chest pain or heart problems. This includes nitroglycerin, isosorbide dinitrate, and isosorbide mononitrate. Nitrates are also found in some recreational drugs such as amyl nitrate or nitrite ("poppers"). Taking vardenafil with a nitrate medicine can cause a sudden and serious decrease in blood pressure.

Tell your doctor if you have ever had:

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, most of whom also had heart disease, diabetes, high blood pressure, high cholesterol, or certain pre-existing eye problems, and in those who smoked or were 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.

Staxyn may contain phenylalanine. Talk to your doctor before using this form of vardenafil if you have phenylketonuria (PKU).

How should I take vardenafil?

Staxyn (vardenafil disintegrating tablets) should not be used in place of Levitra (vardenafil regular tablets). Avoid medication errors by using only the form and strength your doctor prescribes.

Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

Vardenafil can be taken with or without food.

Remove an orally disintegrating (Staxyn) tablet from the package only when you are ready to take the medicine. Place the tablet in your mouth and allow it to dissolve without chewing. Swallow several times as the tablet dissolves. Do not take Staxyn with liquid.

Vardenafil is 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.

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.

Store at room temperature away from moisture and heat.

If you receive medical care for heart problems, tell your caregivers when you last took vardenafil.

What happens if I miss a dose?

Since vardenafil is used as needed, you are not likely to be on a dosing schedule.

Do not take vardenafil more than once a day. Allow 24 hours to pass between doses.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

What should I avoid while taking vardenafil?

Grapefruit may interact with vardenafil and lead to unwanted side effects. Avoid the use of grapefruit products.

Drinking alcohol can increase certain side effects of vardenafil.

Do not use any other drug to treat impotence unless your doctor tells you to.
