Class II U.S. Food and Drug Administration

Tandem Diabetes Care, Inc. t:slim X2 insulin pump with Interoperable Technology recall: A software defect in versions 7.9.0.1 and 7.10.1 of the pump software

Recall published 12 months ago

A software defect in versions 7.9.0.1 and 7.10.1 of the pump software for Tandem t:slim X2 and version 7.9.0.1 of the Tandem Mobi pump with Control-IQ+ technology that are paired with a G7 sensor may result in an unexpected automatic insulin correction bolus (autobolus ) which could result in hypoglycemia.

The hazard: Device malfunction

The notice describes a specific failure mode. That detail is what a clinician needs, because the right action differs sharply between a monitor, an implant and a test kit.

What the notice says: A software defect in versions 7.9.0.1 and 7.10.1 of the pump software for Tandem t:slim X2 and version 7.9.0.1 of the Tandem Mobi pump with Control-IQ+ technology that are paired with a G7 sensor may result in an unexpected automatic insulin correction bolus (autobolus ) which could result in hypoglycemia.

Why it matters: The device may not perform as intended — a mechanical failure, a software defect, an inaccurate reading, or an alarm that does not sound. For a device someone depends on, the consequence of the failure is usually worse than the failure itself.

Symptoms and when to call a doctor

If the device supports a vital function, do not disable or remove it on your own judgement. Contact the clinician who prescribed or fitted it, and use the back-up arrangement they gave you. Go to an emergency department if the symptoms the device is meant to manage are getting worse, or if an implanted device gives an unexpected alarm or shock.

This page is general information, not medical advice. If you feel unwell, a clinician who can see you is the only person able to judge your case.

What to do about Malfunction

Tandem Diabetes Care, Inc. — The notice describes a specific failure mode. That detail is what a clinician needs, because the right action differs sharply between a monitor, an implant and a test kit.

  1. Match the model, catalogue, lot and serial numbers on your device against the identifiers listed on this page.
  2. If the device is implanted, or you depend on it daily, speak to your clinician before changing anything about how you use it.
  3. Check whether the remedy is a software update, and if so confirm afterwards in the device menu that the version actually changed.
  4. If you are a clinic or facility, quarantine affected stock and record the correction in your recall log.

Claiming on a recalled device

Device recalls are tracked by serial and lot number, so your claim moves faster if you lead with those.

  • Have the model, catalogue, lot and serial numbers ready before you call — they are on the device label or its box.
  • Ask explicitly whether your unit is in the affected range; many recalls cover only part of a model line.
  • If you need the device daily, ask what interim arrangement they offer while the remedy is carried out.
  • Log the date, the name and the reference number of every call. Device recalls can run for months.
