From the Food and Drug Administration:
“The U.S. Food and Drug Administration is warning consumers that homeopathic teething tablets and gels may pose a risk to infants and children. The FDA recommends that consumers stop using these products and dispose of any in their possession.
Homeopathic teething tablets and gels are distributed by CVS, Hyland’s, and possibly others, and are sold in retail stores and online.
Consumers should seek medical care immediately if their child experiences seizures, difficulty breathing, lethargy, excessive sleepiness, muscle weakness, skin flushing, constipation, difficulty urinating, or agitation after using homeopathic teething tablets or gels.”
