Summary
Clomipramine is a strongly serotonergic tricyclic, so adding linezolid raises the risk of serotonin syndrome. Severe cases can involve hyperthermia and neuromuscular rigidity.
What this interaction means in plain words
Clomipramine and Linezolid 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.
Clomipramine belongs to Central Nervous System; Linezolid belongs to Anti Bacterial.
Why it happens
Linezolid MAO inhibition combined with clomipramine serotonin reuptake blockade increases synaptic serotonin.
What to do
Avoid if possible and choose another antibiotic. If linezolid is required, withhold clomipramine and monitor for serotonin toxicity.
