Levitra

 
What is Levitra and why is it prescribed?
Levitra relaxes muscles within the penis. This allows increased blood flow into the penis which is necessary to achieve and maintain an erection. Levitra is used to treat erectile dysfunction (impotence). Do not take Levitra if you are taking any of the following medicines: a nitrate such as nitroglycerin (Nitrostat, Nitrolingual, Nitro-Dur, Nitro-Bid, Minitran, Deponit, Transderm-Nitro, others), isosorbide dinitrate (Dilatrate-SR, Isordil, Sorbitrate), isosorbide mononitrate (Imdur, ISMO, Monoket), and others; a recreational drug such as amyl nitrate or nitrite ("poppers"); or an alpha blocker such as doxazosin (Cardura), guanadrel (Hylorel), prazosin (Minipress), terazosin (Hytrin), alfuzosin (Uroxatral), tamsulosin (Flomax), and others. Taking Levitra with any of these medications may cause very low blood pressure, possibly resulting in dizziness, fainting, stroke, or heart attack. Contact your doctor or seek emergency medical attention for any erection that lasts longer than 4 hours. A sustained erection can damage the penis. Refrain from further sexual activity and notify your doctor it you develop dizziness, nausea, or angina (pain, tightness, discomfort, numbness, or tingling in the chest, arms, neck, or jaw) during sexual activity. Do not take Levitra more than once a day. In some cases, use of Levitra may be restricted to once every 72 hours (3 days).

How should you take Levitra?
Follow your doctors directions for taking Levitra. Take each dose with a full glass of water. Levitra can be taken with or without food. Levitra is usually taken when needed. Generally, it is taken about 1 hour before sexual activity. Levitra can help achieve an erection when sexual stimulation occurs. An erection will not occur just by taking a pill. Levitra should not be taken with grapefruit or grapefruit juice. Levitra can interact with grapefruit and grapefruit juice, and the interaction may have dangerous effects.
