The FDA is warning parents and caregivers to stop using homeopathic teething tablets and gels, sold in retail stores and online, to soothe teething in infants and small children.

The U.S. Food and Drug Administration says the teething tablets and gels pose a risk to young children, including possible seizures and other side effects.

Consumers are told to seek medical care immediately if their child experiences seizures, difficulty breathing, lethargy, excessive sleepiness, muscle weakness, flushed skin, or other issues after using the tablets or gels.

“Teething can be managed without prescription or over-the-counter remedies,” said Janet Woodcock, M.D., director of the FDA’s Center for Drug Evaluation and Research in a press release. “We recommend parents and caregivers not give homeopathic teething tablets and gels to children and seek advice from their health care professional for safe alternatives.”

The FDA is currently investigating the issue, testing products and analyzing reported adverse effects to the treatments.

Hyland’s Teething Tablets were recalled in 2010, after the FDA found they contained inconsistent amounts of belladonna.
