Assessment of the Prevalence and Level of Awareness of Medication Overuse Headache Among the General Population in Makkah City, Saudi Arabia

Background: Medication overuse headache (MOH) is a secondary headache condition caused by consistently using more medication than necessary to treat headache symptoms. MOH is defined as a headache that occurs for 15 or more days per month in a patient with a pre-existing primary headache, and it develops as a result of regular overuse of symptomatic headache medication for more than three months. Patients with headaches often use simple pain medication for 15 or more days per month (e.g., non-steroidal anti-inflammatory drugs (NSAIDs) and paracetamol) and 10 or more days per month of opioids, triptans, and combination analgesics, but when there is no relief from these medications, the headache progression can lead to a cycle of consuming more medication with increased pain, which can lead to MOH. Objective: This study aimed to assess the prevalence and awareness of MOH among the general population of Makkah, Saudi Arabia. Methods: A cross-sectional study was conducted between December 2022 and March 2023 using a self-administered online questionnaire disseminated through social media. Data were collected from females and males 18 years of age and older living in Makkah, Saudi Arabia. Results: Overall, 715 individuals completed the questionnaire, 497 of whom were female (69.5%). The average age of the participants was 32.9 years (±13.3 years). The prevalence of MOH among those who reported having experienced headaches throughout their lifetimes was estimated to be 4.5%. Only 134 people (18.7%) were determined to be aware of MOH. Conclusion: This study demonstrated that the general population of Makkah has a high prevalence of MOH and low levels of MOH awareness.
