How to Use chlorhexidine
This medicine should be used immediately after brushing and flossing. Rinse all toothpaste completely from your mouth. Follow the directions on the prescription label. The cap on the original container may be used to measure the dose. If you do not have the cap, ask your pharmacist for a device to measure the dose. Swish the medicine in your mouth for 30 seconds. Do not swallow it. Use the medicine full strength. Do not mix with water before using. Do not eat or drink for several hours after using the rinse. This may decrease the effect of the medicine.
Talk to your pediatrician regarding the use of this medicine in children. Special care may be needed.
They need to know if you have any of the following conditions:
- front tooth fillings, dentures or other mouth appliances, especially those having rough surfaces

- an unusual or allergic reaction to chlorhexidine, other medicines, foods, dyes, or preservatives
- pregnant or trying to get pregnant
If you miss a dose, use it as soon as possible. If it is almost time for your next dose, use only that dose. Do not use double or extra doses.
Visit your dentist every 6 months for dental cleanings and to check on your progress.
This medicine may have a bitter aftertaste. Do not rinse your mouth after using this medicine because that will increase the bitter taste. Rinsing will also decrease the effect of the medicine.
