75% of women receive opioid prescriptions after C-sections with a median of 30 tablets, most go unused, and up to 26,000 women per year develop persistent opioid use from this single exposure

Cesarean delivery is the most common inpatient surgery in the United States, performed approximately 1.2 million times per year. More than 75% of these women fill an opioid prescription upon discharge, and for many, this is their first-ever exposure to opioids. The standard prescription is approximately 30 tablets — far more than most women need. Studies consistently show that the majority of dispensed opioids go unused, creating a large pool of leftover pills in homes with newborns and other children. But the prescribing is not just wasteful; it is dangerous: systematic reviews show that 0.12% to 2.2% of women develop persistent opioid use after cesarean delivery. At 1.2 million C-sections per year, that means as many as 26,400 new mothers annually continue using opioids past the fourth trimester — a pipeline from the maternity ward to opioid dependence. The harm compounds in both directions. Overprescribing creates addiction risk and puts unused narcotics into circulation. But underprescribing or rapid opioid cessation also causes harm: inadequate pain management after C-section is associated with chronic pain, postpartum depression, impaired infant care, and difficulty breastfeeding. The clinical challenge is that there is no standardized, individualized pain management protocol for post-cesarean recovery. Most hospitals use a one-size-fits-all approach: prescribe 30 tablets of oxycodone and tell the patient to call if she needs more. There is no routine follow-up on pain levels, no step-down protocol transitioning from opioids to NSAIDs, and no mechanism to identify the women who are taking more than expected (a red flag for developing dependence). The structural problem is that post-discharge pain management falls into a gap between specialties. The surgeon (OB-GYN) considers the operation complete. The pediatrician is focused on the baby. The primary care physician may not see the mother for weeks. Nobody owns the pain management transition. Meanwhile, the opioid prescription was written in 30 seconds during a hectic discharge process, defaulting to whatever the standard order set contains. Quality improvement studies in 2024 have shown that individualized prescribing — using validated tools to predict opioid need and prescribing accordingly — can dramatically reduce excess prescribing while maintaining pain control. But changing the default order set in a hospital's EHR requires navigating pharmacy committees, anesthesia departments, and surgical culture. Most hospitals have not done it.
