Peridex (Chlorhexidine) Dosage and Side Effects

PERIDEX mouthwash is often used to treat gingivitis, which is a gum disease that causes swollen, red, and bleeding gums.

It's also been used to decrease the risk of mouth sores in people with weakened immune systems, and to prevent pneumonia in hospitalized patients who are on a ventilator.

Proper Use of this medication

PERIDEX rinse is typically used twice daily (once in the morning and once at night).

Your dose will be based on your medical condition and response to treatment.

Typically, you'll rinse your mouth with 15 milliliters (ml) of undiluted PERIDEX for 30 seconds after brushing.

Swish the solution around in your mouth and spit it out. Don't swallow the rinse or mix it with another substance.

Try to use PERIDEX rinse at the same time each day. Use it regularly to see the most benefits.

Wait at least 30 minutes before brushing your teeth, eating, drinking, or rinsing your mouth with water or mouthwash.

PERIDEX Overdose

If you suspect an overdose, contact a poison control center or emergency room immediately.

Missed Dose of PERIDEX

If you miss a dose of PERIDEX rinse, use it as soon as you remember.

However, be sure to brush your teeth first.

Skip the missed dose if it's almost time for your next dose.

Don't take extra medicine to make up for a missed dose.
