Class II · Moderate risk Terminated Initiated Apr 28, 2017 (9 years ago)

Buprenorphine HCI Injection (Buprenorphine Hydrochloride)

Class II — Moderate risk. May cause temporary or reversible harm; serious harm unlikely.

Why it was recalled

Crystallization: due to the presence of white, crystalline particulates, adhered to the side and bottom of the glass vials, which are comprised of principally dextrose and the buprenorphine active component.

Cause type: Failed specification

A physical or chemical test other than potency, dissolution, impurity or stability failed - pH, viscosity, appearance, tablet integrity, fill volume. A product outside its own specification may not perform as designed, even if the active ingredient is present. All failed specification recalls.

FDA recall number
D-0698-2017 · FDA notice

Check, then ask. Class II means harm is possible but usually temporary or reversible. Find the lot number on your package; if it matches, ask your pharmacist about a replacement. Do not simply stop a prescribed medication on your own - the gap can be riskier than the recall. This recall is now terminated, which means the firm has finished removing the affected product; anything on pharmacy shelves today should be unaffected.
