Abstract

Medication overuse headache (MOH) is a common secondary headache disorder in which chronic headaches develop or worsen due to frequent and excessive intake of medications used for acute headache treatment. While the concept of MOH is widely recognized among headache specialists, ongoing debates exist regarding its causes, diagnostic criteria, and treatment strategies. Treating MOH has traditionally been challenging, and there is currently no universal consensus on how to effectively manage patients with MOH. Furthermore, a specific treatment approach based on well-powered randomized trials is still lacking. The treatment strategy for MOH typically involves several steps: patient education and counseling, withdrawal of overused medications, preventive drug therapy, and non-pharmacological prevention. It is recommended that all patients discontinue the overused medication, which can be carried out on an outpatient or inpatient basis. Additionally, topiramate, Botox, and anti-calcitonin gene-related peptide monoclonal antibodies have shown potential in reducing headache and migraine frequency, as well as acute drug consumption, even without active drug withdrawal. However, many aspects of MOH management require further investigation through properly designed and adequately powered randomized controlled trials.
