Medication-overuse headache in patients with cluster headache.
Medication-overuse headache (MOH) in cluster headache (CH) patients is incompletely described, perhaps because of the relatively low prevalence of CH. ⋯ Medication-overuse headache is a previously underrecognized and treatable problem associated with cluster headache (CH). CH patients should be carefully monitored, especially those with a personal or family history of migraine.
