Levitra
Generic name: vardenafil [ var-DEN-a-fil ]
Drug class: Impotence agents
The Levitra brand name has been discontinued in the U.S. If generic versions of this product have been approved by the FDA, there may be generic equivalents available.
What is Levitra?
Levitra (vardenafil) belongs to a class of medications called phosphodiesterase (PDE) inhibitors. Vardenafil relaxes muscles found in the walls of blood vessels and increases blood flow to particular areas of the body.
Levitra works by increasing blood flow to the penis during sexual stimulation. This increased blood flow can cause an erection.
Levitra is used to treat erectile dysfunction (impotence; inability to get or keep an erection) in men.
Levitra does not cure erectile dysfunction or increase sexual desire. This medicine does not prevent pregnancy or the spread of sexually transmitted diseases such as human immunodeficiency virus (HIV).
Warnings
Some medicines can cause unwanted or dangerous effects when used with Levitra. Tell your doctor about all your other medicines, especially riociguat (Adempas).
Do not take Levitra 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 vardenafi with a nitrate medicine can cause a sudden and serious decrease in blood pressure.
Call 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 this medicine 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 Levitra if you are allergic to vardenafil, or if you take other medicines to treat pulmonary arterial hypertension, such as riociguat (Adempas).
Do not take Levitra if you are also using a nitrate drug for chest pain or heart problems, including 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.
To make sure Levitra is safe for you, 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;
-
seizure (convulsions);
-
a blood cell disorder such as sickle cell anemia, multiple myeloma, or leukemia;
-
a bleeding disorder such as hemophilia;
-
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);
-
if you have been told you should not have sexual intercourse for health reasons; or
-
liver disease, kidney disease (or if you are on dialysis).
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.
Levitra is not approved for use in women, and the effects of this medicine during pregnancy or in breastfeeding women are unknown.
How should I use Levitra?
Take Levitra exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets.
Levitra can be taken with or without food.
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.
Levitra 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.
Call 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.
If you receive medical care for heart problems, tell your caregivers when you last took Levitra.
This medicine does not prevent the spread of sexually transmitted diseases such as human immunodeficiency virus (HIV).
Store at room temperature away from moisture and heat.
