Clonazepam, an anxiety drug, is being voluntarily recalled for the potential to cause a “life-threatening” event.

What Happened? Pharmaceutical company Endo Inc. issued the recall after discovering that cartons of the anti-anxiety drug were mislabeled with incorrect dosage strengths and National Drug Codes (NDCs).

Additional packages of clonazepam, a prescription medication used to treat seizures and anxiety, mislabeled with the incorrect strength have been added to a voluntary recall, according to the U.S. Food and Drug Administration.
