Levitra is manufactured by: GlaxoSmithKline. LEVITRA is a prescription medicine taken by mouth for the treatment of erectile dysfunction (ED) in men.ED is a condition where the penis does not harden and expand when a man is sexually excited, or when he cannot keep an erection. A man who has trouble getting or keeping an erection should see his doctor for help if the condition bothers him. LEVITRA may help a man with ED get and keep an erection when he is sexually excited. LEVITRA does not: - cure ED - increase a man's sexual desire - protect a man or his partner from sexually transmitted diseases, including HIV. Speak to your doctor about ways to guard against sexually transmitted diseases. - serve as a male form of birth control - LEVITRA is only for men with ED. LEVITRA is not for women or children. LEVITRA must be used only under a doctor's care. Caution Do not take LEVITRA if you: - take any medicines called "nitrates" (See "What important information should you know about LEVITRA?"). Nitrates are commonly used to treat angina. Angina is a symptom of heart disease and can cause pain in your chest, jaw, or down your arm. - Medicines called nitrates include nitroglycerin that is found in tablets, sprays, ointments, pastes, or patches. Nitrates can also be found in other medicines such as isosorbide dinitrate or isosorbide mononitrate. Some recreational drugs called "poppers" also contain nitrates, such as amyl nitrate and butyl nitrate. Do not use LEVITRA if you are using these drugs. Ask your doctor or pharmacist if you are not sure if any of your medicines are nitrates. - take medicines called "alpha-blockers." Alpha-blockers are sometimes prescribed for prostate problems or high blood pressure. If LEVITRA is taken with alpha-blockers, your blood pressure could suddenly drop to an unsafe level. You could get dizzy and faint. - you have been told by your healthcare provider to not 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. - are allergic to LEVITRA or any of its ingredients.

How does Levitra work? What will it do for me?

Levitra belongs to the class of medications called cyclic GMP-specific phosphodiesterase type 5 inhibitors. These medications work by increasing smooth muscle relaxation and allowing blood to flow into the penis. Levitra is used for the treatment of erectile dysfunction (impotence). It helps a man achieve and keep an erection when he is sexually stimulated. Levitra does not increase sex drive.

Your doctor may have suggested Levitra for conditions other than the ones listed in this drug information article. If you have not discussed this with your doctor or are not sure why you are taking Levitra, speak to your doctor.

Do not give Levitra to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take Levitra if it has not been prescribed by their doctor.

How should I use?

The usual starting dose is 10 mg. Your doctor may recommend a dose as low as 5 mg or as high as 20 mg. Swallow the tablet whole with water. It may be taken with or without food. Levitra should be taken 25 to 60 minutes before sexual activity. It will usually require 15 to 60 minutes to take effect and may last for four to five hours. Do not take Levitra more than once a day.

Because alcohol can make it more difficult to get an erection, do not drink large amounts of alcohol before sexual activity. Moderate amounts of alcohol (two drinks for a 70-kg person) will not interfere with the medication.

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones given here, do not change the way you are taking the medication without consulting your doctor.

It is important to use exactly as prescribed by your doctor.

Who should NOT take Levitra?

Levitra should not be used by anyone who:

is taking any medication that contains nitrates (e.g., amyl nitrate poppers, isosorbide mononitrate, isorbide dinitrate, nitroglycerin)
is taking indinavir or ritonavir (for HIV infection)
is taking ketoconazole or itraconazole (for fungal infections)
is allergic to Levitra or any other ingredients of the medication
Nitrates are found in medications that are used to treat angina (chest pain). If you are not sure if you are taking nitrates, ask your doctor or pharmacist. Nitrates must NOT be taken by anyone who is using Levitra because they can cause your blood pressure to drop very low. This may cause dizziness, fainting, heart attack, or stroke.
