Class II · Moderate risk Terminated Initiated Dec 17, 2018 (8 years ago)

Thymosin Beta-4

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

Why it was recalled

Lack of sterility assurance.

Cause type: Sterility / contamination

A product that must be sterile could not be assured sterile, or was contaminated. A top reason for injectables, eye drops and IV products - loss of sterility assurance can lead to serious infections. All sterility / contamination recalls.

FDA recall number
D-0447-2019 · 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.
