Uses for Control Rx
Fluoride has been found to be helpful in reducing the number of cavities in the teeth. It is usually present naturally in drinking water. However, some areas of the country do not have a high enough level in the water to prevent cavities. To make up for this, extra fluoride may be added to the diet. Some children may require both dietary fluoride and topical fluoride treatments by the dentist. Use of a fluoride toothpaste or rinse may be helpful as well.
Taking extra oral fluoride does not replace good dental habits. These include eating a good diet, brushing and flossing the teeth often, and having regular dental checkups.
Fluoride may also be used for other conditions as determined by your doctor.
This medicine is available only with a prescription.
Importance of Diet
For good health, it is important that you eat a balanced and varied diet. Follow carefully any diet program your health care professional may recommend. For your specific dietary vitamin and/or mineral needs, ask your health care professional for a list of appropriate foods. If you think that you are not getting enough vitamins and/or minerals in your diet, you may choose to take a dietary supplement.
People get needed fluoride from fish, including the bones, tea, and drinking water that has fluoride added to it. Food that is cooked in water containing fluoride or in Teflon-coated pans also provides fluoride. However, foods cooked in aluminum pans provide less fluoride.
The daily amount of fluoride needed is defined in several different ways.
- For U.S.—
- Recommended Dietary Allowances (RDAs) are the amount of vitamins and minerals needed to provide for adequate nutrition in most healthy persons. RDAs for a given nutrient may vary depending on a person's age, sex, and physical condition (e.g., pregnancy).
- Daily Values (DVs) are used on food and dietary supplement labels to indicate the percent of the recommended daily amount of each nutrient that a serving provides. DV replaces the previous designation of United States Recommended Daily Allowances (USRDAs).
- For Canada—
- Recommended Nutrient Intakes (RNIs) are used to determine the amounts of vitamins, minerals, and protein needed to provide adequate nutrition and lessen the risk of chronic disease.
There is no RDA or RNI for fluoride. Daily recommended intakes for fluoride are generally defined as follows:
- Infants and children—
- Birth to 3 years of age: 0.1 to 1.5 milligrams (mg).
- 4 to 6 years of age: 1 to 2.5 mg.
- 7 to 10 years of age: 1.5 to 2.5 mg.
- Adolescents and adults—
- 1.5 to 4 mg.
Remember:
- The total amount of fluoride you get every day includes what you get from the foods and beverages that you eat and what you may take as a supplement.
- This total amount should not be greater than the above recommendations, unless ordered by your health care professional. Taking too much fluoride can cause serious problems to the teeth and bones.
Before using Control Rx
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:
Allergies

Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Pediatric
Problems in children have not been reported with intake of normal daily recommended amounts. Doses of sodium fluoride that are too large or are taken for a long time may cause bone problems and teeth discoloration in children.
Geriatric
Problems in older adults have not been reported with intake of normal daily recommended amounts. Older people are more likely to have joint pain, kidney problems, or stomach ulcers which may be made worse by taking large doses of sodium fluoride. You should check with your health care professional.
Breast Feeding
Studies in women suggest that this medication poses minimal risk to the infant when used during breastfeeding.
Interactions with Medicines
Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.
Interactions with Food/Tobacco/Alcohol
Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive.

Precautions while using Control Rx
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.
