If a patient on a benzodiazepine reports using an MAOI for depression, what is the appropriate clinical action?

• A. The doctor will prescribe a different antidepressant.
• B. Continue benzodiazepine with MAOI.
• C. Increase benzodiazepine dose.
• D. Stop benzodiazepine abruptly.

Answer: (A)

The main concept is that monoamine oxidase inhibitors have dangerous interactions with many other medications, including those used for depression, and they require careful prescribing. When a patient is already taking a benzodiazepine and reports using an MAOI for depression, the safest approach is to avoid continuing the MAOI and switch to an antidepressant that is compatible with benzodiazepine therapy. This minimizes risks such as hypertensive events or serotonin syndrome that can arise from MAOI interactions, while allowing effective management of mood symptoms. Therefore, a physician would prescribe a different antidepressant that does not require an MAOI. Stopping benzodiazepines abruptly or changing the dose of the benzodiazepine isn’t the primary issue here, since the priority is safety with the antidepressant regimen.
