Neostigmine Methylsulfate active pharmaceutical ingredient…

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

Why it was recalled

Penicillin Cross Contamination: All lots of all products repackaged and distributed between 01/05/12 and 02/12/15 are being recalled because they were repackaged in a facility with penicillin products without adequate separation which could introduce the potential for cross contamination with penicillin.

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-815-2015 · 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.
