Medication overuse headache: Updating of the French recommendations regarding the treatment strategies.

Regular and frequent use of analgesics and acute antimigraine drugs can increase the frequency of headache, and induce the transition from episodic to chronic migraine or medication-overuse headache (MOH). The one-year prevalence of this condition is between 1% and 2% in Europe, provoking substantial burden. MOH is more prevalent in people with comorbid depression, anxiety, and other chronic pain conditions. This paper aims at presenting an updating of French recommendations regarding treatments strategies. Prior French recommendations, published in 2014, were written in French. A literature search in the major medical databases including the terms "medication overuse headache", "symptomatic medication overuse", published between 2010 and 2020 was carried out. Three main strategies can be recommended and conducted in parallel: education and explanations about the negative consequences of overusing acute antimigraine drugs, discontinuation of the overused medication, and finally, preventive drug therapy and non-pharmacological prevention. Medication overuse headache remains a debated problem and evidence for the most effective treatment strategy is needed.
