Question
A client taking sertraline receives a new linezolid prescription for a serious infection. Which instruction is appropriate?
1Contact the prescriber before the first dose so the serotonergic regimen and monitoring plan can be reviewed.✓ Correct answer
2Take both drugs as usual because linezolid has no clinically important serotonergic interaction.
3Stop sertraline independently and begin linezolid without telling the mental health prescriber.
4Treat new agitation, sweating, fever, or tremor with an extra dose of sertraline.
Explanation
Linezolid has monoamine oxidase inhibitory activity and can precipitate serotonin syndrome with serotonergic antidepressants such as sertraline. The prescriber must determine whether another antibiotic is suitable or whether coordinated interruption and monitoring are required. The client should not take the combination without review, independently stop an antidepressant, or take more sertraline if serotonin-syndrome symptoms develop.
Clinical reasoning Linezolid can increase serotonergic activity enough to cause serotonin syndrome when combined with an SSRI. Serious infection and antidepressant withdrawal risks both require a coordinated plan.
Decision rule Pause before the first linezolid dose, contact the prescribing team, and monitor for mental-status, autonomic, and neuromuscular changes if combined or sequential therapy is required.
