Medication overuse headache
Abstract
The frequent use (>15 times/month) of medication for the treatment of acute migraine attacks may cause medication overuse headache. This kind of headache can be caused by the intake of a combination of analgesics, opioids, ergot alkaloids and triptans. The delay between first intake and these attacks is shortest for triptans (1-2 years), longer for ergots (3-5 years) and longest for analgesics (5-10 years). Treatment includes drug withdrawal followed by structured acute therapy and initiation of migraine prophylactic treatment.
