Merck (NYSE: MRK), known as MSD outside the United States and Canada, is voluntarily recalling one lot of CUBICIN® (daptomycin for injection) 500 mg for intravenous use, Lot 934778, Exp June 2022. Because treatment with CUBICIN is likely to be initiated at a hospital or other monitored healthcare setting, the recall is being conducted to the user level, including hospital and administering institutions. Approximately 22,000 vials are affected by this recall. The recall has been initiated following receipt of a customer complaint reporting that a piece of glass was found in a vial of CUBICIN after reconstitution.

Intravenous infusion of glass particulates has the potential to cause serious health consequences if the particulate is small enough to be withdrawn from the vial and infused into the patient. Local irritation or swelling at the infusion site may occur in response to the presence of foreign material. More serious potential outcomes include blockage and clotting in blood vessels, which can be life-threatening if a critical organ is affected. Other clinical consequences could include prolonged hospitalization, particularly in those patients receiving an extended treatment regimen for which multiple vials of CUBICIN are administered over the course of treatment. The risk is reduced by the possibility of detection, as the label contains a clear statement directing the healthcare professional to visually inspect the product for particulate matter prior to administration. To date, Merck has not received any reports of adverse events related to this recall.
