Sandoz is initiating a voluntary nationwide recall expansion of one additional lot of Cefazolin for Injection, USP, 1 gram per vial. The lot is being recalled due to a customer complaint indicating that four (4) vials incorrectly labelled as Penicillin G Potassium for Injection, USP, 20 million Units were included in cartons (25 vials per carton) of Cefazolin for Injection, USP 1 gram per vial product. Sandoz has confirmed that the vials incorrectly labelled as Penicillin G Potassium for Injection contain Cefazolin for Injection, USP, 1 gram per vial.
There is a reasonable probability that the inadvertent administration of cefazolin injection following dosing recommendation of penicillin G potassium injection due to mislabeling may pose serious and potentially life-threatening adverse health consequences, including lack of efficacy leading to less than optimal treatment of severe infections, antibiotic resistance, adverse reactions, severe allergic reactions (e.g., anaphylaxis), drug interactions, and delayed recovery.
To date, Sandoz has not received any reports of adverse events or injuries related to the product mislabeling. Sandoz has received a complaint of administration of the incorrectly labelled product to a patient.
Lots impacted by the voluntary recall and its expansion:

Cefazolin for Injection USP is used for the treatment of infections caused by certain bacteria in many different parts of the body including the treatment of pneumonia.

Penicillin G Potassium for Injection is indicated for use in adults, adolescents, children, pediatric, newborn infants and preterm infants.
Although both Cefazolin and Penicillin G Potassium belong to the beta-lactam group of antibiotics, they are indicated for different types of infections, and the spectrum of susceptible organisms also differs. Additionally, while the patient populations overlap, each medicine has specific on-label distinct groups, and the dosing regimens may differ, as well.
