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

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:
- heart disease, heart rhythm problems;
- a heart attack, stroke, or congestive heart failure;
- long QT syndrome (in you or a family member);
- 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, 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, 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.
Staxyn may contain phenylalanine. Talk to your doctor before using this form of vardenafil if you have phenylketonuria (PKU).
Vardenafil is not for use in women, and the effects of this medicine during pregnancy or in breastfeeding women are unknown.

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.
