Description:
<jats:p>Medication-overuse headache is defined as headache occurring on more than 15days in a month in people with pre-existing primary headache, and developing as a consequence of regular overuse of acute headache treatments. Medication-overuse headache is common in general neurology clinics and can be difficult to manage. Most patients have a background of migraine, which has slowly transformed over months and years from the episodic to chronic form; with this comes an increased use of acute migraine treatment. This paper identifies who is at risk of developing medication-overuse headache, and reviews preventive measures and current treatment strategies.</jats:p>
