Tandem t:slim Mobile App Recalled for Defect Affecting Therapy Decisions

Sign in to monitor this recall

Summary

Tandem Diabetes Care, Inc. is recalling approximately 19 units of its Tandem t:slim Mobile App (Android Software Version 2.9.1) used with the t:slim X2 Insulin Pump. The recall affects users in Israel who have their mobile phones set to a right-to-left language (such as Hebrew or Arabic). A software defect causes the app to fail to pair correctly with the pump and creates graphical errors, which can cause users to make incorrect treatment decisions. Consumers should consult their healthcare provider for instructions on managing their insulin therapy while using the pump without the app.

Risk

The software defect can lead to incorrect pump therapy decisions and graphical display errors. This poses a significant risk of hypoglycemia (dangerously low blood sugar) or hyperglycemia (dangerously high blood sugar) if a user receives too much or too little insulin based on faulty app information.

What You Should Do

  1. This recall affects the Tandem t:slim Mobile App (Android Software Version 2.9.1) used in conjunction with the t:slim X2 Insulin Pump on Android devices set to right-to-left languages.
  2. Check your device serial number and mobile software version to see if your configuration is affected. See the Affected Products section below for the full list of affected codes.
  3. Stop using the Tandem t:slim mobile app to monitor or manage your insulin therapy if your phone is set to a right-to-left language.
  4. Contact Tandem Diabetes Care, Inc. directly for instructions on how to receive a software correction or update for the application.
  5. Consult with your healthcare provider or physician to discuss safe alternatives for monitoring your insulin pump while the mobile app functionality is disabled.
