WARNING

ADDICTION, ABUSE, and MISUSE; LIFE-THREATENING RESPIRATORY DEPRESSION; ACCIDENTAL INGESTION; and NEONATAL OPIOID WITHDRAWAL SYNDROME

Addiction, Abuse, and Misuse

MS CONTIN 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 MS CONTIN, and monitor all patients regularly for the development of these behaviors or conditions [see WARNINGS AND PRECAUTIONS].

Life-Threatening Respiratory Depression

Serious, life-threatening, or fatal respiratory depression may occur with use of MS CONTIN. Monitor for respiratory depression, especially during initiation of MS CONTIN or following a dose increase. Instruct patients to swallow MS CONTIN tablets whole; crushing, chewing, or dissolving MS CONTIN tablets can cause rapid release and absorption of a potentially fatal dose of morphine [see WARNINGS AND PRECAUTIONS].

Accidental Ingestion

Accidental ingestion of even one dose of MS CONTIN, especially by children, can result in a fatal overdose of morphine [see WARNINGS AND PRECAUTIONS].

Neonatal Opioid Withdrawal Syndrome

Prolonged use of MS CONTIN during pregnancy can result in neonatal opioid withdrawal syndrome, which may be life-threatening if not recognized and treated, and requires management according to protocols developed by neonatology experts. If opioid use is required for a prolonged period in a pregnant woman, advise the patient of the risk of neonatal opioid withdrawal syndrome and ensure that appropriate treatment will be available [see WARNINGS AND PRECAUTIONS].
