Summary
Meclizine has anticholinergic and sedating properties that oppose the prokinetic action of metoclopramide. Both drugs can also cause CNS effects such as drowsiness, and metoclopramide can cause extrapyramidal symptoms.
What this interaction means in plain words
Meclizine and Metoclopramide intranasal can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Pharmacodynamic antagonism of gastric motility by anticholinergic effects, with additive CNS depression.
What to do
Avoid combining where possible, since the two have opposing effects on gastrointestinal motility. If both are needed, monitor for reduced metoclopramide efficacy, sedation and movement disorders.
