Metoclopramide for migraine-associated hiccup.

Persistent hiccup can be a distressing disorder. I present a case of migraine-attack-associated sustained hiccup. Metoclopramide can swiftly control both hiccup and migraine headache. Vasopressin release probably underlies migraine-aborting action of metoclopramide while restoration of oesophageal smooth muscle function involves competitive dopaminergic antagonism and a prominent cholinergic agonist activity. Episodic prolonged hiccup associated with nausea is an unusual presenting feature of migraine.
