Michelle Ewing of The Statesman reports the deaths of 10 children may be linked to homeopathic tablets that claim to relieve babies’ teething pain, according to the Food and Drug Administration.

FDA is looking into the deaths and 400 “adverse events” reported to the agency.

“The relationship of these deaths to the homeopathic teething products has not yet been determined and is currently under review,” the FDA said in a statement, according to CNN.

The news comes less than two weeks after the FDA warned parents against using the products amid reports of infants and children having seizures, difficulty breathing, lethargy and other health issues after taking the tablets.

On Tuesday, Hyland’s announced it will no longer distribute its teething products in the U.S.
