Drug Interactions

Adverse Reactions

The following adverse drug reactions and incidences are derived from product labeling unless otherwise specified.

Frequency not defined.

Dermatologic: Skin rash

Gastrointestinal: Dental discoloration (with products containing stannous fluoride; temporary), nausea

Hypersensitivity: Hypersensitivity reaction

Warnings/Precautions

Concerns related to adverse effects:

• Dental fluorosis/osseous: Prolonged ingestion with excessive doses may result in dental fluorosis and osseous changes, especially if the water fluoridation exceeds 0.6 ppm; do not exceed recommended dosage.

Special populations:

• OTC products: Swallowing should be minimized with topical products (eg, creams, gels, rinses). OTC products are generally not recommended for use in children <6 years of age unless as directed by a health care provider.

Dosage form specific issues:

• Benzyl alcohol and derivatives: Some dosage forms may contain sodium benzoate/benzoic acid; benzoic acid (benzoate) is a metabolite of benzyl alcohol; large amounts of benzyl alcohol (≥99 mg/kg/day) have been associated with a potentially fatal toxicity (“gasping syndrome”) in neonates; the “gasping syndrome” consists of metabolic acidosis, respiratory distress, gasping respirations, CNS dysfunction (including convulsions, intracranial hemorrhage), hypotension, and cardiovascular collapse (AAP ["Inactive" 1997]; CDC, 1982); some data suggests that benzoate displaces bilirubin from protein binding sites (Ahlfors, 2001); avoid or use dosage forms containing benzyl alcohol derivative with caution in neonates. See manufacturer’s labeling.

• Latex: Packaging of some products may contain natural latex/natural rubber.

• Polysorbate 80: Some dosage forms may contain polysorbate 80 (also known as Tweens). Hypersensitivity reactions, usually a delayed reaction, have been reported following exposure to pharmaceutical products containing polysorbate 80 in certain individuals (Isaksson, 2002; Lucente 2000; Shelley, 1995). Thrombocytopenia, ascites, pulmonary deterioration, and renal and hepatic failure have been reported in premature neonates after receiving parenteral products containing polysorbate 80 (Alade, 1986; CDC, 1984). See manufacturer’s labeling.

• Propylene glycol: Some dosage forms may contain propylene glycol; large amounts are potentially toxic and have been associated with hyperosmolality, lactic acidosis, seizures, and respiratory depression; use caution (AAP 1997; Zar 2007).

• Tartrazine: Some products contain tartrazine.

Other warnings/precautions:

• Appropriate use: Dietary fluoride supplements are recommended for children at high risk of developing dental caries. They are not recommended for use in children <6 months of age, or any child at low risk. All sources of fluoride should be considered prior to preventive intervention (Rozier 2010).

Pregnancy Risk Factor B Pregnancy Considerations

Fluoride crosses the placenta and can be found in the fetal circulation (IOM, 1997). Adverse events have not been observed in animal reproduction studies; epidemiological studies in areas with high levels of fluorinated water have not shown an increase in adverse effects. Heavy exposure in utero may be linked to skeletal fluorosis seen later in childhood.
