Abstract
Background
Dependence‐like behaviour may complicate withdrawal and increase risk of relapse of medication overuse headache (MOH). The most effective treatment for reducing dependence‐like behaviour is unknown.
Objectives
To compare patient‐reported outcomes among three treatment strategies for MOH. The primary outcome was change in Severity of Dependence Scale (SDS) score from baseline to six months.
Methods
Patients with MOH were randomized to 1) withdrawal combined with preventive medication from start (W+P), 2) preventive medication without withdrawal (P), or 3) withdrawal with optional preventive medication two months after withdrawal (W). At baseline, two, and six months, patients filled out SDS (used for measurements of dependence‐like behaviour and treatment feasibility), Headache Under‐Response of Treatment (HURT) and WHO Quality of Life BREF questionnaires.
Results
Out of 120 patients with MOH, 100 completed the six‐month follow‐up and filled out questionnaires. The W+P arm was the most effective in treating MOH. After six months, the SDS score was reduced by 3.69 (95 % CI 3.23 to 4.49) in the W+P arm, by 3.19 (95 % CI 2.43 to 3.96) in the W arm, and by 1.65 (95 % CI 0.96 to 2.33) in the P arm (P = 0.04). At baseline and after two months, the P arm was considered the most feasible treatment, but at six‐month follow‐up, there was no difference in feasibility score, change in HURT score, or quality of life.
Conclusions
Dependence‐like behaviour was reduced most in the two withdrawal arms. Withdrawal combined with preventive medication is recommended for the treatment of MOH.
