Class II · Moderate risk Terminated Initiated Dec 19, 2017 (9 years ago)

Divalproex Sodium Delayed Release Tablets USP

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

Why it was recalled

Cross Contamination With Other Products: metronidazole powder was found in one bottle of Divalproex Sodium.

Cause type: Cross-contamination

Traces of another drug - most often penicillin - got into the product from shared equipment or facilities. Even trace penicillin can trigger a severe allergic reaction in someone who was never meant to receive it. All cross-contamination recalls.

FDA recall number
D-0228-2018 · 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.
