Boxed warning

SERIOUS AND LIFE-THREATENING RISKS FROM USE OF METHADONE HYDROCHLORIDE TABLETS:.

Addiction, Abuse, and Misuse Because the use of methadone hydrochloride tablets exposes patients and other users to the risks of opioid addiction, abuse, and misuse, which can lead to overdose and death, assess each patient's risk prior to prescribing and reassess all patients regularly for the development of these behaviors and conditions [ see Warnings and Precautions (5.1) ]. Life-Threatening Respiratory Depression Serious, life-threatening, or fatal respiratory depression may occur with use of methadone hydrochloride tablets, especially during initiation or following a dosage increase. To reduce the risk of respiratory depression, proper dosing and titration of methadone hydrochloride tablets are essential [see Warnings and Precautions (5.2) ]. Accidental Ingestion Accidental ingestion of even one dose of methadone hydrochloride tablets, especially by children, can result in a fatal overdose of methadone [see Warnings and Precautions (5.2) ]. Risks From Concomitant Use With Benzodiazepines Or Other CNS Depressants Concomitant use of opioids with benzodiazepines or other central nervous system (CNS) depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death.
