Summary
Metoclopramide can cause neurotoxicity and extrapyramidal effects, and reports suggest lithium may increase this risk. Both drugs can cause tremor, rigidity and confusion, making the problem hard to separate from lithium toxicity.
What this interaction means in plain words
Lithium 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
Probable pharmacodynamic synergy on central dopaminergic blockade; the exact mechanism is not firmly established.
What to do
Prefer a different antiemetic or prokinetic when possible. If used together, monitor for extrapyramidal symptoms, neurological changes and lithium toxicity, and check serum lithium if symptoms appear.
