What is Levitra?
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.
How does Levitra work?
When a man is sexually stimulated, his body’s normal physical response is to increase blood flow to his penis. This results in an erection. Levitra helps increase blood flow to the penis and may help men with ED get and keep an erection satisfactory for sexual activity. Once a man has completed sexual activity, blood flow to his penis decreases, and his erection goes away.
Who can take Levitra?
Talk to your doctor to decide if Levitra is right for you.
Levitra has been shown to be effective in men over the age of 18 years who have erectile dysfunction, including men with diabetes or who have undergone prostatectomy.
What is the most important information I should know about Levitra?
Levitra can cause your blood pressure to drop suddenly to an unsafe level if it is taken with certain other medicines. With a sudden drop in blood pressure, you could get dizzy, faint, or have a heart attack or stroke.
Do not take Levitra if you:
- Take any medicines called “nitrates” (often used to control chest pain, also known as angina).
- Use recreational drugs called “poppers” like amyl nitrate and butyl nitrate.
- Take riociguat (Adempas), a guanulate cyclase stimulator, a medicine that treats pulmonary arterial hypertension and chronic-thromboembolic pulmonary hypertension.
(See "Who should not take Levitra?")
Tell all your healthcare providers that you take Levitra. If you need emergency medical care for a heart problem, it will be important for your healthcare provider to know when you last took Levitra.
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 riociguat, a guanylate cyclase stimulator, a medicine that treats pulmonary arterial hypertension and chronic-throembolic pulmonary hypertension.
- 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.

Can other medications affect Levitra?
Tell your doctor about all the medicines you take including prescription and non-prescription medicines, vitamins, and herbal supplements. Levitra and other medicines may affect each other. Always check with your doctor before starting or stopping any medicines. Especially tell your doctor if you take any of the following:
- Medicines called nitrates (see “What important information should you know about Levitra?”).
- Ketoconazole or itraconazole (such as Nizoral or Sporanox).
- Ritonavir (Norvir) or indinavir sulfate (Crixivan) saquinavir (Fortavase or Invirase) or atazanavir (Reyataz).
- Erythromycin or clarithromycin.
- Medicines called alpha-blockers. These include Hytrin (terazosin HCl), Flomax (tamsulosin HCl), Cardura (doxazosin mesylate), Minipress (prazosin HCl), Rapaflo (silodosin) or Uroxatral (alfuzosin HCl). Alpha-blockers are sometimes prescribed for prostate problems or high blood pressure. In some patients the use of PDE5 inhibitor drugs, including Levitra, with alpha-blockers can lower blood pressure significantly leading to fainting. You should contact the prescribing physician if alpha-blockers or other drugs that lower blood pressure are prescribed by another healthcare provider.
- Medicines that treat abnormal heartbeat. These include quinidine, procainamide, amiodarone and sotalol.
- Other medicines or treatments for ED.
How should I take Levitra?
Take Levitra exactly as your doctor prescribes. Do not take more than one Levitra a day. Doses should be taken at least 24 hours apart. Some men can only take a low dose of Levitra because of medical conditions or medicines they take. Your doctor will prescribe the dose that is right for you.
- If you are older than 65 or have liver problems, your doctor may start you on a lower dose of Levitra.
- If you have prostate problems or high blood pressure, for which you take medicines called alpha-blockers, your doctor may start you on a lower dose of Levitra.
- If you are taking certain other medicines your doctor may prescribe a lower starting dose and limit you to one dose of Levitra in a 72-hour (3 days) period.
Take 1 Levitra tablet about 1 hour (60 minutes) before sexual activity. Some form of sexual stimulation is needed for an erection to happen with Levitra. Levitra may be taken with or without meals.
Do not change your dose of Levitra without talking to your doctor. Your doctor may lower your dose or raise your dose, depending on how your body reacts to Levitra.
Call your doctor or emergency room immediately if you accidentally took more Levitra than prescribed.
What are the possible side effects of Levitra?
The most common side effects with Levitra are. headache, flushing, stuffy or runny nose, indigestion, upset stomach, dizziness or back pain. These side effects usually go away after a few hours. Call your doctor if you get a side effect that bothers you or one that will not go away.
Levitra may uncommonly cause:
- An erection that won’t go away (priapism). If you get an erection that lasts more than 4 hours, get medical help right away. Priapism must be treated as soon as possible or lasting damage can happen to your penis including the inability to have erections.
- Color vision changes, such as seeing a blue tinge to objects or having difficulty telling the difference between the colors blue and green.
In rare instances, men taking PDE5 inhibitors (oral erectile dysfunction medicines, including Levitra) reported a sudden decrease or loss of vision in one or both eyes. It is uncertain whether PDE5 inhibitors directly cause the vision loss. If you experience a sudden decrease or loss of vision, stop taking PDE5 inhibitors, including Levitra, and call a doctor right away.
Sudden loss or decrease in hearing, sometimes with ringing in the ears and dizziness, has been rarely reported in people taking PDE5 inhibitors, including Levitra. It is not possible to determine whether these events are related directly to the PDE5 inhibitors, to other diseases or medications, to other factors, or to a combination of factors. If you experience these symptoms, stop taking Levitra and contact a doctor right away.
These are not all the side effects of Levitra. For more information, ask your doctor or pharmacist.
Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
