WARNING: ADDICTION, ABUSE, AND MISUSE; LIFE-THREATENING RESPIRATORY DEPRESSION; ACCIDENTAL INGESTION; ULTRA-RAPID METABOLISM OF TRAMADOL AND OTHER RISK FACTORS FOR LIFE-THREATENING RESPIRATORY DEPRESSION IN CHILDREN; NEONATAL OPIOID WITHDRAWAL SYNDROME; INTERACTIONS WITH DRUGS AFFECTING CYTOCHROME P450 ISOENZYMES; HEPATOTOXICITY; and RISKS FROM CONCOMITANT USE WITH BENZODIAZEPINES OR OTHER CNS DEPRESSANTS

Addiction, Abuse, and Misuse

ULTRACET 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 ULTRACET, and monitor 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 ULTRACET. Monitor for respiratory depression, especially during initiation of ULTRACET or following a dose increase [see Warnings and Precautions (5.2)] .

Accidental Ingestion

Accidental ingestion of even one dose of ULTRACET, especially by children, can result in a fatal overdose of tramadol [see Warnings and Precautions (5.2)] .

Ultra-Rapid Metabolism of Tramadol and Other Risk Factors for Life-Threatening Respiratory Depression in Children

Life-threatening respiratory depression and death have occurred in children who received tramadol. Some of the reported cases occurred following tonsillectomy and/or adenoidectomy, and in at least one case, the child had evidence of being an ultra-rapid metabolizer of tramadol due to a CYP2D6 polymorphism [see Warnings and Precautions (5.3)] . ULTRACET is contraindicated in children younger than 12 years of age and in children younger than 18 years of age following tonsillectomy and/or adenoidectomy [see Contraindications (4)] . Avoid the use of ULTRACET in adolescents 12 to 18 years of age who have other risk factors that may increase their sensitivity to the respiratory depressant effects of tramadol. [see Warnings and Precautions (5.3)]

Neonatal Opioid Withdrawal Syndrome

Prolonged use of ULTRACET 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 (5.4)] .

Interactions with Drugs Affecting Cytochrome P450 Isoenzymes

The effects of concomitant use or discontinuation of cytochrome P450 3A4 inducers, 3A4 inhibitors, or 2D6 inhibitors with tramadol are complex. Use of cytochrome P450 3A4 inducers, 3A4 inhibitors, or 2D6 inhibitors with ULTRACET requires careful consideration of the effects on the parent drug, tramadol, and the active metabolite, M1 [ see Warnings and Precautions (5.5), Drug Interactions (7)].

Hepatotoxicity

ULTRACET contains tramadol hydrochloride and acetaminophen. Acetaminophen has been associated with cases of acute liver failure, at times resulting in liver transplant and death. Most of the cases of liver injury are associated with the use of acetaminophen at doses that exceed 4,000 milligrams per day, and often involve more than one acetaminophen-containing product [see Warnings and Precautions (5.6)].

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 [see Warnings and Precautions (5.7) and Drug Interactions (7)] .

  • Reserve concomitant prescribing of ULTRACET and benzodiazepines or other CNS depressants for use in patients for whom alternative treatment options are inadequate. Reserve concomitant prescribing of ULTRACET and benzodiazepines or other CNS depressants for use in patients for whom alternative treatment options are inadequate.
  • Limit dosages and durations to the minimum required. Limit dosages and durations to the minimum required.
  • Follow patients for signs and symptoms of respiratory depression and sedation. Follow patients for signs and symptoms of respiratory depression and sedation.

1 INDICATIONS AND USAGE

ULTRACET tablets are indicated for the management of acute pain severe enough to require an opioid analgesic and for which alternative treatments are inadequate.

Limitations of Use

ULTRACET tablets are indicated for short-term use of five days or less.

Because of the risks of addiction, abuse, and misuse with opioids, even at recommended doses [see Warnings and Precautions (5.1)] , reserve ULTRACET for use in patients for whom alternative treatment options [e.g., non-opioid analgesics]:

  • Have not been tolerated, or are not expected to be tolerated,Have not been tolerated, or are not expected to be tolerated,
  • Have not provided adequate analgesia, or are not expected to provide adequate analgesia.Have not provided adequate analgesia, or are not expected to provide adequate analgesia.
