Abstract
Because of a risk of precipitated withdrawal occurring from buprenorphine induction in people who use fentanyl, low-dose inductions are becoming increasingly common. However, little evidence exists on the use of this method in pregnant people. We conducted a case series of all pregnant people treated for opioid use disorder with low-dose buprenorphine induction at the University of Maryland Medical Center between January 1, 2021, and August 22, 2022. Primary outcome was completion of induction regimen. Secondary outcomes were self-report of withdrawal, continuation of buprenorphine until delivery, and return to or continuation of illicit opioid use. Six pregnant people were prescribed a total of 10 buprenorphine inductions. Five of the 6 pregnant people (83.3%) completed at least 1 induction, none of whom experienced precipitated withdrawal. Two of 6 (33.3%) continued buprenorphine until the time of delivery, and 1 of 6 (16.7%) abstained from illicit opioid use. The low-dose buprenorphine induction regimen described was successful in 5 of 6 pregnant individuals. Further research, particularly regarding continuation rates, is needed.
