For healthcare professionals — reference only. This page is a brief summary, not medical advice and not a substitute for official labeling or clinical judgement. Always verify before prescribing or dispensing.
Summary
Metoclopramide may increase blood pressure, and its use with MAOIs can enhance hypertensive effects. It can also cause extrapyramidal and serotonergic-type adverse effects, so the pairing complicates management of MAOI-treated patients.
What this interaction means in plain words
Isocarboxazid and Metoclopramide intranasal 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.
Why it happens
Metoclopramide may promote catecholamine release, which is potentiated by MAO inhibition; the mechanism is not fully established.
What to do
Avoid the combination and use a different antiemetic or prokinetic strategy. If used, monitor blood pressure closely and watch for hypertensive symptoms.
What to ask your pharmacist
