Chlorhexidine Gluconate

(klor-HEX-ih-deen GLUE-koe-nate) 

Chlorhexidine gluconate (Peridex) is a medicine used to clean the mouth and treat redness and swelling of the gums.

It is available as a mouth rinse.

  • After measuring the chlorhexidine, have your child swish the medicine in the mouth for 30 seconds. Do not mix it with anything, including water or other medicines.
  • Have your child spit out the medicine after rinsing for 30 seconds. Do not swallow.
  • If your child does swallow a small amount of chlorhexidine, it is not harmful.
  • After rinsing with chlorhexidine, do not eat or drink for 30 minutes. Your child should not even take sips of water. This will help the medicine stay in contact with the inside of the mouth, which makes it work best.
  • Store at room temperature and away from direct light. To make it taste better it can be refrigerated. Do not freeze.
  • Chlorhexidine may stain teeth and fillings. Brushing and flossing more often and/or before using the rinse can reduce this.
  • Chlorhexidine may increase tartar formation on your child's teeth. It is important to see the dentist every six months.
  • Chlorhexidine may cause food to taste different. It is best to have your child use it after meals.
  • Keep this medication out of the reach of children.
  • If too much medication is taken by accident, call the Drug and Poison Information Center (DPIC), 513-636-5111 or 1-800-222-1222 or call your child's doctor right away.

For any medication information related to your child's dosing schedule and/or missed doses, contact the healthcare provider who prescribed the medication.
