Levitra 20 Mg

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).

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.

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 vardenafi with a nitrate medicine can cause a sudden and serious decrease in blood pressure.
