What is chlorhexidine gluconate?
Chlorhexidine gluconate is a germicidal mouthwash that reduces bacteria in the mouth.
Periogard is used to treat gingivitis (swelling, redness, bleeding gums). Chlorhexidine gluconate is usually prescribed by a dentist.
Periogard is not for treating all types of gingivitis. Use the medication only to treat the condition your dentist prescribed it for. Do not share this medication with another person, even if they have the same gum symptoms you have.
Chlorhexidine gluconate may also be used for purposes not listed in this medication guide.
Chlorhexidine gluconate can cause a rare but serious allergic reaction that may be life-threatening. Get emergency medical help if you have: hives, severe skin rash; wheezing, difficult breathing; cold sweats, feeling light-headed; swelling of your face, lips, tongue, or throat.
Do not give this medication to a child or teenager without a doctor's advice. This medicine may cause severe irritation or chemical burns in young children.

How should I use chlorhexidine gluconate?
Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.
Rinse your mouth with chlorhexidine gluconate twice daily after brushing your teeth.
Measure your dose using the cup provided with the medication. Swish the medicine in your mouth for at least 30 seconds, then spit it out. Do not swallow the mouthwash.
Do not add water to the oral rinse. Do not rinse your mouth with water or other mouthwashes right after using chlorhexidine gluconate.
Chlorhexidine gluconate may leave an unpleasant taste in your mouth. Do not rinse your mouth to remove this taste after using the medication. You may rinse the medicine away and reduce its effectiveness.
Use this medication for the full prescribed length of time. Your symptoms may improve before your gingivitis is completely cleared. Chlorhexidine gluconate will not treat a viral or fungal infection such as cold sores, canker sores, or oral thrush (yeast infection).
Visit your dentist at least every 6 months for preventive tooth and gum care.
Store chlorhexidine gluconate at room temperature away from moisture and heat.
What happens if I miss a dose?
Use the missed dose as soon as you remember, but brush your teeth first. Skip the missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222, especially if a child has swallowed 4 or more ounces of this medicine.
An overdose of chlorhexidine would occur only if the medicine were swallowed. Overdose symptoms may include nausea, stomach pain, or the appearance of being drunk.
What should I avoid while taking chlorhexidine gluconate?
Chlorhexidine gluconate can stain teeth, dentures, tooth restorations, your tongue, or the inside of your mouth. Talk with your dentist about ways to remove staining from these surfaces. Stains may be harder to remove from false teeth that have scratches in their surfaces.
Avoid eating, drinking, or brushing your teeth just after using this medication.
Do not use any other mouthwash unless your doctor has told you to.
