Important Notice: Buprenorphine Recall

We have recently learned of a recall issued by Par Health for specific lots of Buprenorphine Injection 0.3mg/mL, 1mL (details outlined in the table below).

This voluntary recall was initiated due to the potential for the presence of white, crystalline product particulates which are comprised of the drug product formulation, principally Buprenorphine free base.

These products were shipped to distributors – including MWI Animal Health (MWI) – beginning on June 11, 2025.
