Case series: Voluntary discontinuation of sublingual buprenorphine treatment for opioid use disorder using extended-release buprenorphine.

The cases reported here provide preliminary support for the use of XR-BUP to help individuals discontinue buprenorphine treatment. There is only one other case series showing the use of XR-BUP in helping individuals successfully discontinue buprenorphine treatment. Buprenorphine discontinuation is clinically relevant and there is little guidance in the current literature.
