Knowing which drug causes methemoglobinemia can be crucial for patients and healthcare providers alike.

According to the U.S. Food and Drug Administration (FDA), the use of oral drug products containing benzocaine, the active ingredient in many Orajel gels, has been linked to a serious, potentially fatal blood disorder called methemoglobinemia.
