FDA Black Box Warning
WARNING: SERIOUS AND LIFE-THREATENING RISKS FROM USE OF TRAMADOL HYDROCHLORIDE AND ACETAMINOPHEN TABLETS Addiction, Abuse, and Misuse Because the use of tramadol hydrochloride and acetaminophen 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 tramadol hydrochloride and acetaminophen, especially during initiation or following a dosage increase. To reduce the risk of respiratory depression, proper dosing and titration of tramadol hydrochloride and acetaminophen are essential [see Warnings and Precautions (5.2)]. Accidental Ingestion Accidental ingestion of even one dose of tramadol hydrochloride and acetaminophen, especially by children, can result in a fatal overdose of tramadol [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. Reserve concomitant prescribing of tramadol hydrochloride and acetaminophen and benzodiazepines or other CNS depressants for use in patients for whom alternative treatment options are inadequate [see Warnings and Precautions (5.3) and Drug Interactions (7)]. Neonatal Opioid Withdrawal Syndrome (NOWS) If opioid use is required for an extended period of time in a pregnant woman, advise the patient of the risk of NOWS, which may be life-threatening if not recognized and treated. Ensure that management by neonatology experts will be available at delivery [see Warnings and Precautions (5.4)]. Opioid Analgesic Risk Evaluation and Mitigat
Contraindications
Tramadol hydrochloride and acetaminophen tablets are contraindicated for: all children younger than 12 years of age [see Warnings and Precautions (5.6)] post-operative management in children younger than 18 years of age following tonsillectomy and/or adenoidectomy [see Warnings and Precautions (5.6)]. Tramadol hydrochloride and acetaminophen tablets are also contraindicated in patients with: Significant respiratory depression [see Warnings and Precautions (5.2)]. Acute or severe bronchial asthma in an unmonitored setting or in the absence of resuscitative equipment [see Warnings and Precautions (5.13)]. Patients with known or suspected gastrointestinal obstruction, including paralytic ileus [see Warnings and Precautions (5.18)]. Previous hypersensitivity to tramadol, acetaminophen, any other component of this product, or opioids [see Warnings and Precautions (5.19)]. Concurrent use of monoamine oxidase inhibitors (MAOIs) or use within the last 14 days [see Drug Interactions (7)].

Tramadol/Apap + ErythromycinUnknown
Examples: Macrolide antibiotics (e.g., erythromycin), azole-antifungal agents (e.g., ketoconazole), protease inhibitors (e.g., ritonavir) CYP3A4 Inducers Clinical Impact: The concomitant use of tramadol hydrochloride and acetaminophen and CYP3A4 inducers can decrease the plasma concentration of tramadol [see Clinical Pharmacology (12.3)], resulting in decreased efficacy or onset of a withdrawal syndrome in patients who have developed physical dependence to tramadol.
