We are still in an opioid crisis. The number of women with opioid-related diagnoses at delivery has increased by 131% over the last several years (CDC, Data and Statistics, 2023). The ACOG has recommended the use of opioid agonist pharmacotherapy for MOUD during pregnancy. Traditionally, medically supervised withdrawal has not been endorsed for pregnancy. However, some patients may elect to discontinue opioid therapy in favor of an opioid antagonist like naltrexone. In this episode, we will review a new systematic review just released ahead-of-print in Obstetrics and Gynecology. This systematic review evaluates OB and neonatal outcomes following naltrexone use during pregnancy. And listen in until the END of the episode for one of the “issues” with naltrexone as a MOUD option.
