Lead: The association between buprenorphine doses above 16 milligrams and treatment retention in a multi-payer national sample in the United States, 2014 to 2021

The association between buprenorphine doses above 16 milligrams and treatment retention in a multi-payer national sample in the United States, 2014 to 2021

Addiction

Buprenorphine labeling identifies 16 mg as the “target dose,” supported by prior evidence that higher doses (≥16 mg) were associated with increased retention in treatment. Studies comparing doses above 16 mg to 16 mg, particularly in the era of fentanyl, have been very limited. The authors conducted a cohort study to look at retention for those receiving 24, 32, and 40 mg compared to 16 mg. Overall, higher doses were associated with increased retention, as follows: 1) 24 mg was more effective than 16 mg at 1 (aOR=1.52) and 18 months (aOR=1.17), 2) 32 mg was more effective than 24 mg at 6 (aOR=1.06), 12 (aOR=1.09), and 18 months (aOR=1.12), and 3) 40 mg was more effective than 24 mg at 12 (aOR=1.10) and 18 months (aOR=1.18). The authors suggest updates to label language and recommendations are prudent, while also supporting more research on long-term treatment with these higher doses.
