Summary

Linezolid is a reversible non-selective MAO inhibitor, and combining it with opioids can cause serotonin syndrome or excitatory reactions. Remifentanil has minimal serotonin reuptake inhibition, but caution is needed because of the severity of the reaction.

What this interaction means in plain words

Linezolid and Remifentanil can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.

Linezolid belongs to Anti Bacterial; Remifentanil belongs to Musculoskeletal.

Evidence level: Moderate

Why it happens

MAO inhibition by linezolid increases serotonergic and monoamine activity, adding to opioid effects.

What to do

Avoid the combination if an alternative antibiotic or analgesic is feasible. If it is necessary, monitor closely for serotonin toxicity and stop the serotonergic agents if signs appear.

What to ask your pharmacist
