Medication overuse headache (MOH) is a common form of chronic headache with a high risk of relapse after therapy. Excessive use of analgesics most frequently leads to the development of MOH in migraine patients. Objective : to analyze the short- and long-term efficacy of MOH therapy in patients with chronic migraine (CM) using different programs to discontinue the abused drug and a detoxification regimen. Material and methods. The study included 44 patients with MOH and CM who were divided into two groups. Group A comprised 18 patients who discontinued the drug that triggered MOH and were simultaneously prescribed preventive treatment for migraine without undergoing "detoxification" therapy". Group B comprised 26 patients who received a multimodal therapeutic strategy including "detoxification treatment". Results. The strategy of complex therapy with a "detoxification treatment" was significantly more effective during the 12-month observation period. In group B, a significant (p<0.01) decrease in the number of days with migraine per month was observed (before therapy – 22.6±7.4 days, after 3 months – 15.1±8.9 days, after 6 months – 12.7±9.1 days and after 12 months – 10.2±8.7 days). In the first 6 months, a similar dynamic was observed in group A, whereby the frequency of migraine increased in the 12th month of observation. Twelve months after the start of therapy, migraine occurred in episodes in the majority (84%) of patients in group B, which is significantly more than in group A (58.9%; p<0.01). Conclusion . A comprehensive approach in the treatment of patients with CM and MOH with "detoxification" therapy" showed high efficacy in terms of reducing the number of headache days per month and converting CM to episodic migraine.
