Tandem recalls t:slim X2 and Mobi insulin pumps with Dexcom G7 sensors using specific software versions that may cause unexpected insulin doses leading to low blood sugar.
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.
Tandem is recalling insulin pumps that pair with Dexcom G7 sensors and have specific software versions. These pumps might deliver extra insulin without warning, causing dangerously low blood sugar levels.
The software defect in certain versions may cause the pump to automatically deliver extra insulin (an autobolus) when paired with a Dexcom G7 sensor. This can lead to hypoglycemia, or dangerously low blood sugar levels, which can cause confusion, seizures, or coma if severe.
People using Tandem t:slim X2 or Mobi insulin pumps with Dexcom G7 sensors and specific software versions are affected. Those with diabetes who rely on these pumps for insulin delivery are most at risk.
Check for the pump model (t:slim X2 or Mobi) and software version numbers (7.9.0.1 or 7.10.1 for t:slim X2, 7.9.0.1 for Mobi) when paired with a Dexcom G7 sensor. The product has specific reference numbers listed in the recall notice.
Look for the software version on your pump's display or in the user guide. Versions 7.9.0.1 or 7.10.1 for t:slim X2 and 7.9.0.1 for Mobi are affected.
Contact Tandem support to update to a newer software version that fixes this issue. They may provide a software update or replacement pump.
No, the recall does not require immediate stoppage. You can continue using the pump but should update the software to a newer version to avoid the risk.
