Alprazolam XR is contraindicated in patients: • with known hypersensitivity to alprazolam or other benzodiazepines. Angioedema has been reported [see Adverse Reactions (6.2) ] . • taking strong cytochrome P450 3A (CYP3A) inhibitors (e.g., ketoconazole, itraconazole), except ritonavir [see Dosage and Administration (2.5) , Warnings and Precautions (5.5) , Drug Interactions (7.1) ] . • Known hypersensitivity to alprazolam or other benzodiazepines. ( 4 ) • Concomitant use with strong cytochrome P450 3A (CYP3A) inhibitors, except ritonavir. ( 4 , 5.5 , 7.1 )

Overdosage of benzodiazepines is characterized by central nervous system depression ranging from drowsiness to coma. In mild to moderate cases, symptoms can include drowsiness, confusion, dysarthria, lethargy, hypnotic state, diminished reflexes, ataxia, and hypotonia. Rarely, paradoxical or disinhibitory reactions (including agitation, irritability, impulsivity, violent behavior, confusion, restlessness, excitement, and talkativeness) may occur. In severe overdosage cases, patients may develop respiratory depression and coma. Overdosage of benzodiazepines in combination with other CNS depressants (including alcohol and opioids) may be fatal [see Warnings and Precautions (5.2) ] . Markedly abnormal (lowered or elevated) blood pressure, heart rate, or respiratory rate raise the concern that additional drugs and/or alcohol are involved in the overdosage. In managing benzodiazepine overdosage, employ general supportive measures, including intravenous fluids and airway management. Flumazenil, a specific benzodiazepine receptor antagonist indicated for the complete or partial reversal of the sedative effects of benzodiazepines in the management of benzodiazepine overdosage, can lead to withdrawal and adverse reactions, including seizures, particularly in the context of mixed overdosage with drugs that increase seizure risk (e.g., tricyclic and tetracyclic antidepressants) and in…

Use with Opioids: Increase the risk of respiratory depression. ( 7.1 ) • Use with Other CNS Depressants: Produces additive CNS depressant effects. ( 7.1 ) • Use with Digoxin: Increase the risk of digoxin toxicity. ( 7.1 ) • Use with CYP3A Inhibitors (except ritonavir): Increase the risk of adverse reactions of alprazolam. ( 4 , 5.5 , 7.1 ) • Use with CYP3A Inducers: Increase the risk of reduced efficacy of alprazolam. ( 7.1 ) 7.1 Drugs Having Clinically Important Interactions with Alprazolam XR Table 4 includes clinically significant drug interactions with alprazolam XR [see Clinical Pharmacology (12.3) ] . Table 4: Clinically Significant Drug Interactions with Alprazolam XR Opioids Clinical implication The concomitant use of benzodiazepines and opioids increases the risk of respiratory depression because of actions at different receptor sites in the CNS that control respiration. Benzodiazepines interact at gamma-aminobutyric acid (GABA A ) sites and opioids interact primarily at mu receptors. When benzodiazepines and opioids are combined, the potential for benzodiazepines to significantly worsen opioid‑related respiratory depression exists. Prevention or management Limit dosage and duration of concomitant use of alprazolam XR and opioids, and monitor patients closely for respiratory depression and sedation [see Warnings and Precautions (5.1) ] . Examples Morphine, buprenorphine, hydromorphone, oxymorphone, oxycodone, fentanyl, methadone, alfentanil, butorphanol, codeine, dihydrocodeine, meperidine, pentazocine, remifentanil, sufentanil, tapentadol, tramadol. CNS Depressants Clinical implication The benzodiazepines, including alprazolam, produce additive CNS depressant effects when coadministered with other CNS depressants. Prevention or management Limit dosage and duration of alprazolam XR during concomitant use with CNS depressants [see Warnings and Precautions (5.3) ] . Examples Psychotropic medications, anticonvulsants, antihistaminics, ethanol, and other drugs which themselves produce CNS depression. Strong Inhibitors of CYP3A (except ritonavir) Clinical implication Concomitant use of alprazolam XR with strong CYP3A inhibitors has a profound effect on the clearance of alprazolam, resulting in increased concentrations of alprazolam and increased risk of adverse reactions [see Clinical Pharmacology (12.3) ] . Prevention or management Concomitant use of alprazolam XR with a strong CYP3A4 inhibitor (except ritonavir) is contraindicated [see Contraindications (4) , Warnings and Precautions (5.5) ] . Examples Ketoconazole, itraconazole, clarithromycin Moderate or Weak Inhibitors of CYP3A Clinical implication Concomitant use of alprazolam XR with CYP3A inhibitors may increase the concentrations of alprazolam XR, resulting in increased risk of adverse reactions [see Clinical Pharmacology (12.3) ] . Prevention or management Avoid use and consider appropriate dose reduction when alprazolam XR is coadministered with a moderate or weak CYP3A inhibitor [see Warnings and Precautions (5.5) ] . Examples Nefazodone, fluvoxamine, cimetidine, erythromycin CYP3A Inducers Clinical implication Concomitant use of CYP3A inducers can increase alprazolam metabolism and therefore can decease plasma levels of alprazolam [see Clinical Pharmacology (12.3) ] . Prevention or management Caution is recommended during coadministration with alprazolam. Examples Carbamazepine, phenytoin Ritonavir Clinical implication Interactions involving ritonavir and alprazolam are complex and time dependent. Short term administration of ritonavir increased alprazolam exposure due to CYP3A4 inhibition. Following long term treatment of ritonavir (> 10-14 days), CYP3A4 induction offsets this inhibition. Alprazolam exposure was not meaningfully affected in the presence of ritonavir. Prevention or management Reduce alprazolam XR dose when a patient is initiated with ritonavir and alprazolam XR concomitantly, or when ritonavir is added to a regimen where alprazolam XR is stabilized. Increase alprazolam XR dosage to the target dosage after 10 to 14 days of dosing ritonavir and alprazolam XR concomitantly. No dosage adjustment of alprazolam XR is necessary in patients receiving ritonavir for more than 10 to 14 days [see Dosage and Administration (2.5) ] . Concomitant use of alprazolam XR with a strong CYP3A inhibitor, except ritonavir, is contraindicated [see Contraindications (4) , Warnings and Precautions (5.5) ] . Digoxin Clinical implication Increased digoxin concentrations have been reported when alprazolam was given, especially in geriatric patients (>65 years of age). Prevention or management In patients on digoxin therapy, measure serum digoxin concentrations before initiating alprazolam XR. Continue monitoring digoxin serum concentration and toxicity frequently. Reduce the digoxin dose if necessary. 7.2 Drug/Laboratory Test Interactions Although interactions between benzodiazepines and commonly employed clinical laboratory tests have occasionally been reported, there is no consistent pattern for a specific drug or specific test.
