Levitra

    What Is Levitra Used For?

    Vardenafil, commonly referred to by its brand name, Levitra, is a prescription drug used primarily to treat male sexual function problems, specifically erectile dysfunction or impotence, by increasing blood flow to the penis. In combination with sexual stimulation, Levitra helps men to achieve, and maintain an erection.

    Co-marketed by Bayer Pharmaceuticals, GlaxoSmithKline, and Schering-Plough, Levitra is a PDE5 inhibitor, sold under the alternate brand names Staxyn in India, and Vivanza, in Italy. In the US and Canada, a reformulation of Levitra is also sold under the brand name STAXYN, or Levitra Soft, an orally disintegrating tablet that disintegrates on the tongue without water. PDE5 inhibitors used to treat erectile dysfunction block the degradation of a specific enzyme, cGMP, on the muscle cells of the corpus cavernosum of the penis, thus increasing blood flow.

    Closely related in function to other PDE5 inhibitors Viagra and Cialis, Levitra works by increasing the blood flow to the penis, but differs in its relatively short effective time frame of about 4-5 hours. Beyond its capabilities and uses as an erectile dysfunction treatment, Levitra is also unique in that it may be effective in the treatment of premature ejaculation, increasing the length of time between initial penetration, and ejaculation.

    How To Use Levitra Effectively

    Levitra should be taken as directed by your doctor, usually as needed. It may be taken with or without food, and is usually taken about one hour prior to sexual activity. Doses should be taken at least 24 hours apart. Like all prescription drugs, consult your physician prior to taking Levitra, and let them know about any other prescriptions you may be taking, and any pre-existing medical history you may have.

    If you are using the disintegrating tablet form of Levitra, the recommended single dose is 10-milligrams (mg) no more than once a day, an hour before you expect to have sex.

    If you are using the oral tablet, take a 10-mg single dose once a day an hour before sex. Men age 65 years and older can take a 5-mg dose once a day, an hour before sex.

    The recommended dose of Levitra will be different for different men, however. Talk to your doctor about the correct dosage for you.

    Can You Overdose on Levitra?

    No more than one dose of Levitra every 24 hours should be taken. Call your doctor immediately if you think you've overdosed on Levitra.

    Warnings and Precautions

    LEVITRA Warnings

    In 2007, the FDA issued safety information about LEVITRA and other ED medicines, warning of possible sudden hearing loss in some men.

    The information was issued after a case report in medical literature that described a man having sudden hearing loss after taking Viagra (sildenafil).

    While no direct cause and effect was demonstrated, the FDA said that the link found between the ED drug use and hearing loss in the case report and other reports warranted a change in the label to reflect the potential problem.

    If your erection is painful or continues beyond four hours as a result of taking LEVITRA, you should contact your doctor right away.

    A prolonged erection could cause serious and permanent injury to your penis.

    Pregnancy and LEVITRA

    LEVITRA is only for use in men. Women should never take it, especially if they are pregnant or breastfeeding.

    Interactions with this medication

    Many medicines interact with LEVITRA and should be avoided if possible, including::

    • Dronedarone (Multaq)
    • Fluconazole (Diflucan)
    • Nelfinavir (Viracept)
    • Nitroglycerin (Nitro-BID, Nitro-Dur, others)
    • Posaconazole (Noxafil)
    • Isosorbide Mononitrate (Imdur, Ismo, Monoket)

    If any of these medications are required, you and your doctor will need to weigh the potential risks and benefits of taking them while also taking LEVITRA.

    Your doctor may change the dosage of one or both medicines, as well as how often you take them.
