Vardenafil is used to treat male sexual function problems (impotence or erectile dysfunction-ED). In combination with sexual stimulation, vardenafil 20mg works by increasing blood flow to the penis to help a man get and keep an erection.
Take this medication by mouth as directed by your doctor, usually as needed. Take vardenafil, with or without food, about 1 hour before sexual activity. Do not take more than once daily. Doses should be taken at least 24 hours apart.
The dosage is based on your medical condition, response to treatment, and other medications you may be taking. Be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).
Avoid eating grapefruit or drinking grapefruit juice while using this medication unless your doctor or pharmacist says you may do so safely. Grapefruit can increase the chance of side effects with this medicine. Ask your doctor or pharmacist for more details.
Do not take vardenafil if you are also using a nitrate drug for chest pain or heart problems. This includes nitroglycerin, isosorbide dinitrate, and isosorbide mononitrate. Nitrates are also found in some recreational drugs such as amyl nitrate or nitrite (“poppers”). Taking Levitra with nitrate medicine can cause a sudden and serious decrease in blood pressure.
