11 Jun 2024 --- Abbott has received clearance from the US Food and Drug Administration (FDA) for two new over-the-counter continuous glucose monitoring systems. Libre Rio targets people with type 2 diabetes, while Lingo is designed for adults wanting to understand and improve their health. The new systems are based on Abbott’s FreeStyle sensing technology. Libre Rio is designed for adults with type 2 diabetes who do not use insulin but manage their diabetes with lifestyle modifications.
