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).

The agency warned that adults and children who inadvertently took a higher dose of clonazepam than prescribed could experience side effects, including “significant” sedation, confusion, dizziness, diminished reflexes, the loss of muscle control and muscle weakness.
