Class II FDA device recall · Z-1966-2025

Class II — the FDA judged the product may cause temporary or medically reversible harm, with a remote chance of serious harm.

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. Most recalls are Class II or III.

Allon 2001. Part Number: 200-00263

Why it was recalled

An investigation into a report of the patient wrap (ThermoWrap), used with the Allon device, exceeding the set temperature determined that if: 1. The Human Sensor Board is disconnected from the Controller Board in the Allon device AND the temperature alarms are disabled, or 2. The Water In and Water Out and Thermostat sensors are disconnected from the Human Sensor Board AND the temperature alarms are disabled, the device will proceed to heat the water above the hardware fault limit without notifying the user of the faulty condition.

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.
