USES
Levitra (Vardenafil) is used to treat male sexual function problems (impotence or erective dysfunction) by blocking a certain enzyme (phosphodiesterase-PDE5). In combination with sexual stimulation, Levitra works by helping the blood flow into the penis to achieve and maintain an erection. Levitra is not indicated for use in women. Use of Levitra does not protect against sexually transmitted diseases (e.g., HIV, hepatitis B, gonorrhea, syphilis). Practice "safe sex" such as using latex condoms. Consult your doctor or pharmacist for more details.
HOW TO USE
Levitra is taken by mouth as needed, 1 hour before sexual activity with or without food; or use as directed by your doctor. Do not take more often than once daily as needed. A high fat meal may decrease the amount of Levitra that is absorbed. Avoid eating grapefruit or drinking grapefruit juice while you are being treated with Levitra unless your doctor instructs you otherwise. The dosage is based on your medical condition, response to therapy, and other medications you may be taking (see also Drug Interactions section). Consult your doctor or pharmacist for more details. Read the patient information leaflet provided by your pharmacist and ask questions if any of the information is unclear.
SIDE EFFECTS
Headache, flushing, nasal stuffiness, stomach upset, heartburn, runny nose, dizziness, or nausea may occur. Vision changes such as increased sensitivity to light, blurred vision, or impaired blue/green color discrimination may also occur. If any of these effects persist or worsen, notify your doctor or pharmacist promptly. Tell your doctor immediately if any of these highly unlikely but very serious side effects occur: fast/slow/irregular heartbeat. Sexual activity may put extra strain on your heart, especially if you have heart problems. If you have heart problems and experience any of these serious side effects while having sex, stop and tell your doctor immediately of: severe dizziness, fainting, chest pain.
