Summary

From 1 January 2004 to 31 December 2006 64 individuals with probable medication overuse headache were included in a randomized, 1-year open-labeled, multicentre study to evaluate the effect of early introduction of prophylactic treatment compared to abrupt withdrawal and with a control group (ClinicalTrials.gov number NCT00159588). In this follow-up, randomized patients still alive 4 years after primary inclusion time will be invited to a follow up interview, evaluating the headache complaints and the proportion of recurrent medication overuse.
