The level of fluoride present in the water is different in different parts of the U.S. If you move to another area, check with a health care professional in the new area as soon as possible to see if this medicine is still needed or if the dose needs to be changed. Also, check with your health care professional if you change infant feeding habits (e.g., breast-feeding to infant formula), drinking water (e.g., city water to nonfluoridated bottled water), or filtration (e.g., tap water to filtered tap water).
Do not take calcium supplements or aluminum hydroxide–containing products and sodium fluoride at the same time. It is best to space doses of these two products 2 hours apart, to get the full benefit from each medicine.
Inform your health care professional as soon as possible if you notice white, brown, or black spots on the teeth. These are signs of too much fluoride in children when it is given during periods of tooth development.
