Generic Name: vardenafil (var-DEN-a-fil)
Brand Name: Levitra
Vardenafil is used for:
Treating erectile dysfunction (ED). It may also be used for other conditions as determined by your doctor.
Vardenafil is a phosphodiesterase type 5 (PDE5) inhibitor. It works by helping to increase blood flow into the penis during sexual stimulation. This helps you to achieve and maintain an erection.
Do NOT use vardenafil if:
- you are allergic to any ingredient in vardenafil
- you have been advised by your doctor to avoid sexual activity because of heart problems
- you have certain heart problems (eg, severe heart failure, angina), low or high blood pressure, severe liver problems or severe kidney problems that require dialysis
- you have certain hereditary degenerative eye problems (eg, retinitis pigmentosa)
- you have had a heart attack, stroke, or life-threatening irregular heartbeat within the past 6 months
- you have a history of a certain type of irregular heartbeat (eg, congenital QT prolongation) or you take certain antiarrhythmic medicines (eg, quinidine, procainamide, amiodarone, sotalol)
- you are taking a nitrate (eg, isosorbide, nitroglycerin) in any form (eg, capsule, ointment, patch, tablet), or nitroprusside
- you use certain recreational drugs called "poppers" (eg, amyl nitrate or nitrite, butyl nitrate or nitrite)
- you take another PDE5 inhibitor (eg, sildenafil, tadalafil) or another medicine that contains vardenafil
Contact your doctor or health care provider right away if any of these apply to you.

Important safety information:
- Vardenafil may cause dizziness, drowsiness, fainting, or blurred vision. These effects may be worse if you take it with alcohol or certain medicines. Use vardenafil with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.
- Vardenafil may cause dizziness, lightheadedness, or fainting; alcohol, hot weather, exercise, or fever may increase these effects. To prevent them, sit up or stand slowly, especially in the morning. Sit or lie down at the first sign of any of these effects.
- Patients with heart problems who take vardenafil may be at increased risk for heart-related side effects, including heart attack or stroke. Symptoms of a heart attack may include chest, shoulder, neck, or jaw pain; numbness of an arm or leg; severe dizziness, headache, nausea, stomach pain, or vomiting; fainting; or vision changes. Symptoms of a stroke may include confusion; vision or speech changes; one-sided weakness; or fainting. Contact your doctor or seek medical attention right away if you experience these symptoms.
- Vardenafil may rarely cause a prolonged (more than 4 hours) or painful erection. This could happen even when you are not having sex. If this is not treated right away, it could lead to permanent sexual problems such as impotence. Contact your doctor right away if this happens.
- Vardenafil does not stop the spread of HIV or other sexually transmitted diseases (STDs) to others through sexual contact. Use barrier methods of birth control (eg, condoms) if you have HIV infection or an STD.
- Vardenafil will not prevent pregnancy. If your partner may become pregnant and you wish to avoid pregnancy, be sure to use an effective form of birth control.
- Vardenafil may uncommonly cause mild, temporary vision changes (eg, blurred vision, sensitivity to light, blue/green color tint to vision). Contact your doctor if vision changes persist or are severe.
- Rarely, an eye problem called nonarteritic anterior ischemic optic neuropathy (NAION) has been reported in patients who took vardenafil. This may lead to decreased vision or permanent loss of vision in some cases. If you notice a sudden decrease in vision or loss of vision in one or both eyes, contact your doctor right away.
- Sudden decreases in hearing and loss of hearing have been reported in some patients who have taken vardenafil. Sometimes they also noticed ringing in the ears or dizziness. If you notice a sudden decrease or loss of hearing, contact your doctor right away.
- Do not use other medicines or treatments for ED while you are taking vardenafil without first checking with your doctor.
