Summary
Ephedrine releases norepinephrine and linezolid reduces its breakdown, so pressor responses can be exaggerated. Severe hypertension may occur.
What this interaction means in plain words
Ephedrine 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.
Ephedrine belongs to Cardiovascular; Linezolid belongs to Anti Bacterial.
Why it happens
MAO inhibition enhances the indirect sympathomimetic effect of ephedrine.
What to do
Avoid if possible; if a vasopressor is needed, use a low dose of a direct agent with careful blood pressure titration. Monitor blood pressure continuously.
