In-patient versus out-patient withdrawal programmes for medication overuse headache: A 2-year randomized trial
2011
Background: Medication-overuse headache (MOH) management usually includes a medication withdrawal. The choice of withdrawal modalities remains a matter of debate.Methods: We compared the efficacy of in-patient versus out-patient withdrawal programmes in 82 consecutive patients with MOH in an open-label prospective randomized trial. The main outcome measure was the reduction in number of headache days after 2 months and after 2 years. The responders were defined as patients who had reverted to episodic headaches and to an intake of acute treatments for headache less than 10 days per month.Results: Seventy-one patients had a complete drug withdrawal (n = 36 in the out-patient group; n = 35 in the in-patient group). The reduction of headache frequency and subjective improvement did not differ between groups. The long-term responder rate was similar in the out- and in- patient groups (44% and 44%; p = 0.810). The only predictive factor of a bad outcome 2 years after withdrawal was an initial consumption of mo...
