Background and objective: Medication-overuse headache (MOH) as a secondary chronic headache imposes a considerable burden on both individuals and societies. Nevertheless, little is known about the burden of MOH in Iran. Therefore, in the current study, we aimed to quantify the annual cost of MOH among Iranian patients.
Methods: In this cross-sectional study, 84 patients were recruited. Demographic data, headache attack characteristics, related disability, and information about the economic burden of MOH were collected through face-to-face interview. Direct medical and nonmedical costs as well as indirect costs were included in our cost analysis. The prevalence-based approach was applied to estimate the economic burden of MOH.
Results: We found that MOH patients in Iran spend averagely $1046 for medical services, $132 for nonmedical services, and $1432 due to lost productivity per year. The per-person annual cost of MOH was US$2610, and the total annual cost for Iran was $10,179,000,000, with direct and indirect cost accounting for 45% and 55%, respectively.
Conclusion: MOH leads to substantial healthcare costs and significant loss of productivity in Iran. Therefore, raising awareness in this area especially for policymakers can use in future health planning and lead to resource allocation in the field of disabling type of headache disorders such as MOH. Our findings also provide a different insight into the burden of MOH, which are likely closer to the actual costs in middle- and low-income countries, and also it could be a sample of such a study in western Asia.
