Levitra

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

Levitra is used to treat erectile dysfunction (impotence).

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

Important information

Taking Levitra 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.

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

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.

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.

Taking Levitra 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 if you take a nitrate drug for chest pain or heart problems. Nitrates include nitroglycerin, isosorbide dinitrate, and isosorbide mononitrate. Nitrates are also found in some recreational drugs such as amyl nitrate or nitrite ("poppers").

To make sure Levitra is safe for you, tell your doctor if you have:

heart disease, heart rhythm problems;

a recent history (in the past 6 months) of a heart attack, stroke, or congestive heart failure;

a personal or family history of Long QT syndrome;

high or low blood pressure;

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, history of 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.

Levitra can decrease blood flow to the optic nerve of the eye, causing sudden vision loss. This has occurred in a small number of people taking Viagra or other drugs similar to vardenafil. Most of these people also had certain pre-existing eye problems or risk factors for blood vessel disorders (such as heart disease, diabetes, high blood pressure, high cholesterol, coronary artery disease, smoking, or being over 50 years old). It is not clear whether vardenafil is the actual cause of vision loss.

Although Levitra is not for use in women, this medication is not expected to be harmful to an unborn baby.

Although Levitra 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.

How should I take Levitra?

Take Levitra exactly as prescribed by your doctor. Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.

Levitra can be taken with or without food.

Levitra is usually 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. Follow your doctor's instructions.

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

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.

LEVITRA helps improve erectile function by increasing blood flow to the penis. LEVITRA has helped many men and it may help you, too.

LEVITRA can cause your blood pressure to drop suddenly to an unsafe level if it is taken with certain other medicines. With a sudden drop in blood pressure, you could get dizzy, faint, or have a heart attack or stroke.

If, like millions of other men, you have noticed changes in your erections, you can do something about it. Talking to your doctor is the first step.

Why Choose LEVITRA

LEVITRA (vardenafil HCl) is an FDA -approved oral prescription medication for the treatment of erectile dysfunction (ED) in men. It belongs to a class of drugs called "PDE5 inhibitors."

It works by increasing blood flow to the penis to help improve erectile function. The active ingredient in LEVITRA works specifically on the chain of events that occurs in the penis during arousal, when two large chambers in a man’s penis fill with blood.

Indication
LEVITRA is a prescription medicine used for the treatment of erectile dysfunction (ED) in men.

Important Safety Information

  • LEVITRA can cause your blood pressure to drop suddenly to an unsafe level if it is taken with certain other medicines. With a sudden drop in blood pressure, you could get dizzy, faint, or have a heart attack or stroke.
  • Do not take LEVITRA if you:
    • Take any medications called "nitrates" (often used to control chest pain, also known as angina), or if you use recreational drugs called "poppers" like amyl nitrate and butyl nitrate. Nitrates may cause abnormally low blood pressure and LEVITRA may increase that risk
    • Take riociguat (Adempas ® ), a guanylate cyclase stimulator. a medicine that treats pulmonary arterial hypertension and chronic-thromboembolic pulmonary hypertension
    • Have been told by your healthcare provider not to have sexual activity because of health problems. Sexual activity can put an extra strain on your heart, especially if your heart is already weak from a heart attack or heart disease
  • Tell all your healthcare providers that you take LEVITRA. If you need emergency medical care for a heart problem, it will be important for your healthcare provider to know when you last took LEVITRA.
  • LEVITRA does not protect a man or his partner from sexually transmitted diseases, including HIV.
  • Before taking LEVITRA, tell your doctor about all your medical problems, including if you:
    • have heart problems such as angina, heart failure, irregular heartbeats, or have had a heart attack—ask your doctor if it is safe for you to have sexual activity
    • have low blood pressure or have high blood pressure that is not controlled
    • have pulmonary hypertension
    • have had a stroke

These include Hytrin ® (terazosin HCl), Flomax ® (tamsulosin HCl), Cardura ® (doxazosin mesylate), Minipress ® (prazosin HCl), Uroxatral ® (alfuzosin HCl), or Rapaflo ® (silodosin). Alpha-blockers are sometimes prescribed for prostate problems or high blood pressure. In some patients, the use of PDE5 inhibitor drugs, including LEVITRA, with alpha-blockers can lower blood pressure significantly, leading to fainting.
    • Contact the prescribing physician if alpha-blockers or other drugs that lower blood pressure are prescribed by another healthcare provider
  • Tell your doctor if you take medicines that treat abnormal heartbeat. These include quinidine, procainamide, amiodarone, and sotalol. Patients taking these drugs should not use LEVITRA.
