Abstract

BACKGROUND: Women with endometriosis are prescribed opioids for pain relief but may be vulnerable to chronic opioid use given their comorbidity profile. METHODS: A cohort study was conducted in the Clinformatics™ DataMart database between 2006 and 2017 comparing women aged 18-50 years with endometriosis (N = 36 373) to those without (N = 2 172 936) in terms of risk of chronic opioid use, opioid dependence diagnosis, and opioid overdose. Chronic opioid use was defined as ≥120 days' supply dispensed or ≥10 fills of an opioid during any 365-day interval. Among women with endometriosis, we evaluated factors associated with higher risk of chronic opioid use and quantified the risk of complications associated with the use of opioids. RESULTS: Women with endometriosis were at greater risk for chronic opioid use (OR: 3.76; 95%CI: 3.57-3.96), dependence (OR: 2.73, 95%CI: 2.38-3.13) and overdose (OR: 4.34, 95%CI: 3.06-6.15) compared to women without. Chronic users displayed dose escalation and increase in days supplied over time, as well as co-prescribing with benzodiazepines and sedatives. Approximately 34% of chronic users developed constipation, 20% experienced falls, and 8% reported dizziness. Among endometriosis patients, women in younger age groups, those with other comorbidities associated with pain symptoms, as well as those with depression or anxiety were at a higher risk of developing chronic opioid use. CONCLUSIONS: Women with endometriosis had a four times greater risk of chronic opioid use compared to women without. Multimorbidity among these patients was associated with the elevated risk of chronic opioid use and should be taken into account during treatment selection.
