Tandem Diabetes Care Inc. has initiated a voluntary recall for specific lots of its insulin pump cartridges, the company announced.

Tandem (Nasdaq: TNDM) found that certain cartridges for its t:slim insulin pump could be prone to leak, though no customer complaints have been reported, Tandem said. However, a cartridge leak could potentially cause the device to deliver too much or too little insulin, which could seriously impact a patient’s health, the company said.

Tandem has modified its cartridge manufacturing process to prevent this issue from occurring in the future, Kim Blickenstaff, president and CEO of Tandem, said in a statement.
