Linezolid + Sertraline
STOP — Contraindicated
FDA contraindication — linezolid label states do not use with serotonergic drugs including SSRIs unless life-threatening infection with no alternative antibiotic.
Evidence level: STRONG
What this interaction means
Linezolid (an antibiotic) acts as an MAO inhibitor. Combining it with sertraline (Zoloft) can trigger severe, life-threatening serotonin syndrome. The FDA specifically contraindicates this combination.
How it works (mechanism)
Linezolid is a reversible non-selective MAO inhibitor. Combined with sertraline (SSRI), severe serotonin syndrome risk. FDA label for linezolid contains specific contraindication for serotonergic drugs.
Practical advice
If you take Zoloft and need linezolid, your doctor should stop the SSRI. Linezolid should only be given to patients on SSRIs when the infection is life-threatening and no alternative antibiotics will work.
Timing
Take Sertraline and Linezolid at their usual prescribed times. Some antibiotics (linezolid especially) have serotonergic properties and should never be combined with SSRIs — if you are on linezolid, confirm this combination with your prescriber. Standard antibiotics like amoxicillin or azithromycin are generally safe alongside SSRIs.
Risk factors
Higher risk for: elderly, those on multiple serotonergic drugs, people with liver impairment, CYP2D6 poor metabolizers, recent dose changes, or concurrent use of MAOIs or triptans.
Symptoms to watch for
Confusion, agitation, tremor, high fever, rigid muscles, rapid heart rate, dangerously high blood pressure, seizures, coma
What to tell your doctor
If an infection requires linezolid, discuss stopping the SSRI with a washout period. Ask about alternative antibiotics like vancomycin. Have emergency serotonin syndrome treatment plan.
Safer alternatives
Discuss this combination with your prescriber. They may adjust timing, dosing, or switch to an alternative with fewer interaction risks. Never stop an antidepressant abruptly — taper under medical guidance.
