What to do

Check your product against the names and codes above. The FDA enforcement record lists the recall as voluntary: firm initiated; it does not state a consumer remedy, so follow the firm’s notice or the FDA link.

Company
Tandem Diabetes Care, Inc.
Reason
A beta (early-release) version of the iOS application, version 2.13 (TestFlight) had a software issue preventing successful pairing of the t:slim application with Abbott FreeStyle Libre 3 Plus (FSL3P) continuous glucose monitoring (CGM) sensors, resulting in the insulin pump being unable to establish a near-field communication (NFC) connection with the CGM and requiring FSL3P users to use their t:slim insulin pumps in manual mode. FSL3P users are unable to access their CGM's glucose values from within the t:slim app and cannot use their pumps in automated control (closed-loop) mode, which could lead to users experiencing hypoglycemia or hyperglycemia.
Hazard
FDA Class II: may cause temporary or medically reversible adverse health consequences (FDA definition).
Who’s affected
US Nationwide distribution.
