The /*Food and Drug Administration*/ said there is a link between the numbing medication found in over-the-counter teething relief gels and liquids with a rare blood disorder.
The medication to look for is benzocaine. There is concern it can trigger a rare but potentially fatal condition called methemoglobinemia, which makes the blood unable to carry oxygen effectively throughout the body.
The FDA recommends not using products with benzocaine on children under the age of 2 years old without a doctor's approval.
