Interaction Effect

Increased risk of respiratory and CNS depression


Interaction Summary

In observational studies, coadministration of opioids and benzodiazepines increases the risk of drug-related mortality compared with opioids alone. Coadministration of benzodiazepines (ie, alprazolam) and opioids may result in profound sedation, respiratory depression, coma, and death; reserve for when alterative treatment options are inadequate. Limit dosages and durations to the minimum required; follow patients for signs and symptoms of respiratory depression and sedation. In patients receiving an opioid, prescribe a lower initial dose of alprazolam and titrate based on response; in patients receiving alprazolam, prescribe a lower initial dose of the opioid and titrate based upon response[1][2]. Consider prescribing naloxone for the emergency treatment of opioid overdose [3]. Cessation of benzodiazepines is preferred over concomitant use. Consider using alternative options for the treatment of anxiety or insomnia [4].

How To Manage Interaction

Concomitant use of benzodiazepines, including alprazolam, and opioids may result in profound sedation, respiratory depression, coma, and death. Reserve coadministration for when alterative treatment options are inadequate. Limit dosages and durations to the minimum required and follow patients for signs and symptoms of respiratory depression and sedation. In patients receiving an opioid, prescribe a lower initial dose of alprazolam than indicated in the absence of an opioid and titrate based on response. If an opioid is initiated in a patient taking alprazolam, prescribe a lower initial dose of the opioid and titrate based upon response[1][2]. Consider prescribing naloxone for the emergency treatment of opioid overdose [3]. Cessation of benzodiazepines is preferred over concomitant use with the opioids. Monitoring in a higher level of care or taper may be appropriate. Consider using alternative options for the treatment of anxiety or insomnia [4].


Mechanism Of Interaction

Additive CNS depression


Literature Reports

A) The rate of emergency department visits involving non-medical use of concomitant benzodiazepines and opioid analgesics increased significantly over the period from 2004 to 2011, from 11 visits per 100,000 population to 34.2 visits per 100,000 population. Also, deaths from drug overdose involving concomitant benzodiazepines and opioid analgesics (including both prescribed doses and doses greater than prescribed) increased from 0.6 per 100,000 population to 1.7 per 100,000 population. The proportion of opioid overdose deaths for which benzodiazepines were also implicated increased from 18% to 31% [5].

B) In a prospective cohort study performed in North Carolina, overdose deaths in patients who were dispensed both opioids and benzodiazepines were 10-fold greater than those dispensed opioids alone (7 per 10,000 person-years vs 0.7 per 10,000 person-years). A case-cohort study in the Veterans Health Administration demonstrated that patients taking opioids with a benzodiazepine prescription history or current benzodiazepine prescriptions had an increased risk of death due to overdose compared with patients taking opioids without a history of benzodiazepine prescription, risk increased 2.33- to 3.86-fold in patient with current or historical prescriptions for benzodiazepines. As daily benzodiazepine doses increased, risk of death due to drug overdose increased as well [5].

C) Observational studies demonstrated that concomitant use of opioid analgesics and benzodiazepines increases the risk of drug-related mortality compared to use of opioids alone [1][2].
