The prescribing of opioids for chronic noncancer pain in the menopausal and postmenopausal population: a drug utilisation study in the United Kingdom.

Abstract

Opioid use for chronic noncancer pain (CNCP) is consistently higher in menopausal/postmenopausal women than in younger women or men, elevating their risk of opioid-related adverse health outcomes. Since pain severity increases with hormonal changes accompanying menopause, these women should be a focus of opioid stewardship efforts. To examine opioid prescribing trends for CNCP in menopausal/postmenopausal women diagnosed with a musculoskeletal condition. Population-based drug utilisation study using IQVIA Medical Research Data UK. Annual opioid prescribing incidence, prevalence, and average duration of use were calculated for a cohort of women aged 50-79 with musculoskeletal conditions newly diagnosed between 2010-2021. Specific results were stratified by age, pain indication, and Townsend score. From 2010 to 2021, incident prescribing rates of opioids increased in women aged 50-54 (161.4 [95% CI 149.7-174.0] per 1000 PYAR in 2010 to 239.6 [95% CI 211.7-271.2] per 1000 PYAR in 2021); these women discontinued opioid use faster (~1 year) than older age groups (~2 years). Overall, opioid prescribing prevalence decreased from 23% in 2010 to 14% in 2021, and average opioid use duration decreased from 3 years to 1 year (2010 - post-2017) in women aged 50-79. The overall observed decrease in prevalence and average duration of opioid use is encouraging. Incident prescriptions are rising in women aged 50-54 and those with fibromyalgia while remaining steady in women aged 55-79. Understanding the impact of menopause/post-menopause on opioid use trends is important for effective opioid stewardship.
