Tandem insulin pump Czech guide inverted a key connection instruction

Tandem Diabetes Care is recalling insulin pumps distributed in the Czech Republic and Slovakia because the Czech user guide contains translation errors, including one that inverts an infusion set instruction.

What this means for you

Real risk of harm even if no illness or injury has been reported yet. Stop using the product and follow the agency's guidance.

Our severity reasoning: Rubric level 3 covers risk-of-harm products where injury has not yet been reported: an inverted instruction could lead to unintended insulin delivery and a hypoglycemic event, and no injuries are stated.

Plain-English summary

Tandem Diabetes Care, Inc. is recalling Tandem insulin pumps running version 7.8.1. The pumps are battery-operated infusion pumps capable of basal and bolus delivery of insulin from a disposable cartridge through an infusion set into subcutaneous tissue, with timing and quantity programmed by the user. About 1,380 units were distributed in the Czech Republic and Slovakia. The FDA has classified this recall as Class II.

The Czech language user guide contained multiple translation errors. The most significant error incorrectly instructs users to verify that the infusion set is connected to the body, when it should instead direct users to confirm that the infusion set is not connected to the body. Following this instruction could result in unintended insulin delivery, potentially leading to a hypoglycemic event.

Affected product carries UDI 008500066132625.

Users and clinicians can identify affected pumps by the software version above, and may contact Tandem Diabetes Care, Inc. for further information.
