title: [Headache caused by analgesic abuse].
abstract: OBJECTIVE
  To assess the frequency of migraines attributable to continuous consumption of analgesics.
  
  
  METHODS
  A longitudinal prospective study of a descriptive type.
  
  
  METHODS
  A specialised Neurology Clinic within a County hospital, which provides the Primary Care coverage for ibiza and Formentera.
  
  
  METHODS
  All those patients who were referred to the said clinic over a two-year period.
  
  
  RESULTS
  Nine cases were identified: 1.1% of all patients. The drug involved in 90% of the cases was the aspirin. 100% of the patients were women. Anxiolytics, anti-depressive and Naproxen were used in treatment. In all cases treatment was on an out-patient basis. Over a minimum follow-up period of six months, there was only one relapse.
  
  
  CONCLUSIONS
  The study shows that although the incidence of this condition at a specialist clinic is low due to self-medication and to the fact that none of the patients was referred with this suspected diagnosis, there is an important gap in knowledge within Primary Care about this treatable condition.
