Peridex (Oral)

Chlorhexidine is used to treat gingivitis. It helps reduce inflammation (redness) and swelling of your gums and decreases gum bleeding.

Gingivitis is caused by bacteria that grow in the plaque that forms on your teeth between brushings. Chlorhexidine kills these bacteria, which helps prevent gingivitis. However, chlorhexidine does not stop plaque and tartar from forming; proper tooth brushing and flossing are still necessary and important.

Chlorhexidine is available only with your dentist's or medical doctor's prescription.

Chlorhexidine may leave a bitter aftertaste. Do not rinse your mouth with water right after using chlorhexidine, as this will make the bitterness stronger. Rinsing can also reduce the effectiveness of the medicine.

Chlorhexidine may change how food tastes to you. This effect can sometimes last for up to 4 hours after using the oral rinse. Usually, this effect will become less noticeable as you keep using the medicine. When you stop using chlorhexidine, your taste should go back to normal.

Chlorhexidine might cause staining and increase tartar (calculus) on your teeth. Brushing with a tartar-control toothpaste and flossing daily may help reduce tartar build-up and staining. You should also visit your dentist at least every 6 months for teeth cleaning and gum examination.

If you think a child weighing 22 pounds (10 kilograms) or less has swallowed more than 4 ounces of the dental rinse, get emergency help immediately. Also, if a child of any age drinks the dental rinse and shows signs of alcohol intoxication, like slurred speech, sleepiness, or unsteady walking, seek emergency help right away.

In deciding to use a medicine, you and your doctor need to consider the risks of the medicine against the benefits it will provide. Here are some important points to think about:

Allergies

Inform your doctor if you have ever had any unusual or allergic reactions to this medicine or any other medicines. Also, let your healthcare professional know about any other allergies you have, such as allergies to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Research on this medicine has only been conducted with adult patients, and there is no specific information on how it works in children compared to other age groups.

Geriatric

Many medicines have not been specifically studied in older adults. Therefore, it may not be clear if they work the same way as they do in younger adults or if they cause different side effects or issues in older people. There is no specific information on how this medicine affects the elderly compared to other age groups.

Breast Feeding

Studies in women indicate that this medication poses minimal risk to the infant when used during breastfeeding.

Interactions with Medicines

Some medicines should not be used together at all, while others can be used together even if there might be an interaction. In these cases, your doctor may need to adjust the dose or take other precautions. Inform your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicines.

Interactions with Food/Tobacco/Alcohol

Certain medicines should not be taken around the time of eating food or specific types of food due to possible interactions. Using alcohol or tobacco with certain medicines may also lead to interactions. Talk with your healthcare professional about how to use your medicine with food, alcohol, or tobacco.

Other Medical Problems

Having other medical issues may affect how you can use this medicine. Be sure to tell your doctor about any other medical problems, especially:

• Front-tooth fillings (especially those with rough surfaces)—Chlorhexidine may cause staining that could be permanent and may require replacing the filling.

• Gum problems (other)—Using chlorhexidine may worsen other gum issues, such as periodontitis.

Along with its necessary effects, a medicine may cause some unwanted effects. Although not all of these side effects may happen, if they do, they may need medical attention.

Check with your doctor right away if any of the following side effects occur:

Rare

• Signs of allergic reaction (nasal congestion; shortness of breath or troubled breathing; skin rash, hives, or itching; or swelling of face)

Some side effects may occur that usually do not need medical attention. These side effects may go away during treatment as your body adjusts to the medicine. Also, your health care professional may be able to tell you about ways to prevent or reduce some of these side effects. Check with your health care professional if any of the following side effects continue or are bothersome or if you have any questions about them:

• Increase in tartar (calculus) on teeth
• Staining of teeth, mouth, tooth fillings, and dentures or other mouth appliances
