Drug Interactions
Lorazepam is metabolized by glucuronidation rather than CYP450 enzymes, which means it has fewer pharmacokinetic interactions than many other benzodiazepines. The most important interactions are pharmacodynamic.
- Opioids (e.g., oxycodone, hydrocodone, morphine, fentanyl, tramadol): Profound sedation, respiratory depression, coma, and death. An FDA Boxed Warning applies. Avoid co-prescription when possible; if combined, use the lowest effective doses for the shortest duration with close monitoring.
- Other CNS depressants (alcohol, sedating antihistamines, gabapentinoids, muscle relaxants, sleep aids): Additive sedation, impaired psychomotor performance, falls, and respiratory depression. Counsel against alcohol and recreational sedatives.
- Clozapine: Rare reports of severe respiratory depression, hypotension, and cardiorespiratory arrest when combined with parenteral lorazepam. Avoid IV/IM lorazepam in patients on clozapine.
- Probenecid and valproate: Inhibit lorazepam glucuronidation, increasing lorazepam levels and prolonging effects. Reduce lorazepam dose by approximately 50 percent.
- Theophylline and aminophylline: May antagonize the sedative effects of lorazepam, potentially reducing efficacy for sedation or anxiety.
