Abstract

Headache is one of the most frequent reasons for medical consultation in both general practice and specialist neurology clinics.1 Prescribed and over-the-counter medications are taken to alleviate headaches, but may be used incorrectly.2 In particular, use of some drugs both frequently and regularly can have a paradoxical effect, causing headaches rather than relieving them, and leading to medication overuse headache (MOH).3 Such overuse is a common cause of frequent headache. Here we review MOH and its management.
