  • What is Peridex?

    Peridex reduces bacteria in the mouth. It is an oral rinse used to treat gingivitis (gum disease), a condition in which the gums become red and swollen between dental visits. Peridex is also used to control gum bleeding caused by gingivitis.

  • What is the most important information I should know about Peridex?

    Peridex may stain front-tooth fillings, especially those with a rough surface. These stains have no adverse effect on the gums, and usually can be removed by a professional cleaning. In addition to staining, Peridex can also cause an excess of tartar build-up on your teeth.

    Peridex is used only for gingivitis. If you also have periodontitis (disease of the tissue that supports and attaches the teeth), it may require additional treatment by your doctor or dentist.

  • Who should not take Peridex?

    Do not take Peridex if you are allergic to the medication or any of its ingredients.

  • What should I tell my doctor before I take the first dose of Peridex?

    Tell your doctor about all prescription, over-the-counter, and herbal medications you are taking before beginning treatment with Peridex. Also, talk to your doctor about your complete medical history, especially if you have fillings or other dental work on your front teeth, or if you have periodontitis.

  • What is the usual dosage?

    The information below is based on the dosage guidelines your doctor uses. Depending on your condition and medical history, your doctor may prescribe a different regimen. Do not change the dosage or stop taking your medication without your doctor's approval.

    Adults: The usual dose is 15 milliliters (mL) taken twice daily, in the morning and evening after brushing your teeth. Rinse with Peridex for approximately 30 seconds after brushing your teeth. Spit Peridex out after rinsing. You should never swallow Peridex.

  • How should I take Peridex?

    You should get a thorough dental cleaning and examination before beginning treatment with Peridex. It is recommended that you have your teeth cleaned at least every 6 months. To minimize discoloration, brush and floss daily, emphasizing areas that begin to discolor.

    The use of Peridex may leave a bitter after-taste. This will become less noticeable in most cases with continued use of Peridex. To avoid taste interference, rinse with Peridex after meals. Do not rinse with water or other mouthwashes immediately after rinsing with Peridex.

    After brushing, thoroughly rinsing, and flossing your teeth, rinse with Peridex by swishing 15 mL (marked in the cap) in your mouth for 30 seconds, and then spit it out. Do not swallow the mouthwash. Do not dilute Peridex and do not rinse your mouth with water or other mouthwashes after using Peridex, even if it leaves an unpleasant taste. Also, avoid eating or drinking for at least 1 hour to allow the medication to continue to work.
