Class I — the FDA judged there is a reasonable probability that use of the product would cause serious harm or death.
This is the FDA's risk judgment for this recall. It describes the potential of the product as a category — it does not establish that any specific unit harmed anyone.
Tandem Mobi Insulin Pump: Description/Catalog: Tandem insulin pumps are battery-operated infusion pumps capable of both basal and bolus delivery of insulin. The pumps utilize a motor-driven mechanism to deliver insulin from within a disposable cartridge, through an infusion set, into a patient s subcutaneous tissue. As with current insulin infusion pumps on the U.S. market, the desired timing and quantity of the insulin delivery is programmed by the user (i.e., the patient).

Why it was recalled
Insulin pump includes a vibration motor that gives tactile feedback for any alerts, alarms, or malfunctions. Pump may exhibit false vibration motor failure due to a software issue causing Malfunction 12: "Pump cannot operate, the mobile app can no longer receive data from the pump. Insulin delivery and any active CGM Sessions have been stopped", which could result in hyperglycemia.
Is your unit affected?
The recall covers only the specific lots or serial numbers the FDA listed. Enter the lot or serial number from your product's label and we'll check it against that list.
A match means your unit may be covered — stop and call your pharmacist before doing anything. No match suggests it isn't covered, but confirm anyway: code formats vary and lists can be incomplete. Your unit not being listed does not guarantee it is safe, and being listed does not mean you have been harmed.

What this is — and is not
A recall is a recorded FDA enforcement action — the FDA logged that a firm is removing or correcting a product. It does not establish that any specific unit harmed anyone, and causation is not established by a recall. The class above is the FDA's risk judgment for the product category, not a finding about your unit. This page informs and compares; it is not medical advice and never tells you to start or stop a drug or device.
