What happened

Loaner insulin pumps may have been cleaned with chemically incompatible products that could damage the pump case or keypad, allow moisture ingress, and result in insulin over- or under-delivery, potentially causing hypoglycemia, hyperglycemia, or diabetic ketoacidosis.

Who may be affected

People using a product, model, software version, lot, or UDI listed in the affected-products table and official FDA record.
A mention of the device family does not mean every unit is affected. Compare the identifiers on your product with the official source.

What the official notice recommends

On 7/13/2026, field safety notices were sent to customers asking them to do the following: 1) Stop using the loaner pump and contact the firm to arrange for loaner pump return. 2) Contact your Healthcare Professional (HCP) to ensure you have access to backup insulin therapy supplies or alternative plans, which may include short- and long-acting insulins, syringes, with dosage instructions from your HCP. 3) Complete and return the customer acknowledgement form.
Questions can be directed to the firm's Tech Support: 1-800-646-4633

The official notice takes precedence over this summary. Talk to your clinician before changing prescribed therapy.
