Active Ingredient: Sodium Fluoride 2.2 mg.

Other Ingredients: Cherry flavor, FD&C Red #40, mannitol, magnesium stearate, and microcrystalline cellulose.

Indications & Dosage


It has been established that ingestion of fluoridated drinking water (1 ppm F) during the period of tooth development results in significant decrease in the incidence of dental caries. 1 Sodium fluoride tablets were developed to provide systemic fluoride for use as a supplement in pediatric patients from age 6 months to 16, living in areas where the drinking water fluoride level does not exceed 0.6 ppm F.


See schedule below to determine dosage. Dissolve in the mouth or chew before swallowing, preferably at bedtime after brushing teeth.
