What is Staxyn?

Staxyn (vardenafil) relaxes muscles found in the walls of blood vessels and increases blood flow to particular areas of the body.

Staxyn orally disintegrating tablets are used to treat erectile dysfunction (impotence).

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

Important Information

Taking Staxyn 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.

Do not use Staxyn 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 Staxyn and get emergency medical help if you have sudden vision loss.

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 Staxyn if you are allergic to vardenafil, or if you take other medicines to treat pulmonary arterial hypertension, such as riociguat (Adempas).

Staxyn 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 Staxyn is not for use in women, this medication is not expected to be harmful to an unborn baby and it is not known whether vardenafil 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 use Staxyn?

Staxyn orally 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.

Use Staxyn orally disintegrating tablets exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets.

Remove an orally disintegrating 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.

Staxyn 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.
