when using Basal-IQ technology.1


Predictive technology you can feel good about

The t:slim X2™ insulin pump with Basal-IQ® technology is a small touchscreen insulin pump with a simple-to-use, predictive low-glucose suspend feature designed to reduce the frequency and duration of low-glucose events.


Less time low

of study participants said the Basal-IQ feature on the t:slim X2 insulin pump was easy to use.1


Basal-IQ technology improved overall glycemic control in clinical study participants with no evidence of rebound hyperglycemia.



"Diabetes complicates all aspects of my life. The t:slim X2 with Basal-IQ eased some of these burdens. During my time in the Basal-IQ PROLOG study, the feature shined overnight when I could see that it suspended and protected me from lows."

Clinical Study Subject




t:slim X2 Insulin Pump with Dexcom G6


Zero Fingersticks

With Dexcom G6 continuous glucose monitoring (CGM) integration, the Basal-IQ feature on the t:slim X2 insulin pump does not require fingersticks for calibration or mealtime dosing.*


*If glucose alerts and CGM readings do not match symptoms or expectations, use a blood glucose meter to make diabetes treatment decisions.

Responsible Use of
Basal-IQ Technology

Systems like the t:slim X2 insulin pump with Basal-IQ technology are not substitutes for the active management of diabetes. There are common scenarios in which automated systems cannot prevent a hypoglycemic event. The Basal-IQ feature relies on current CGM sensor readings to function and will not be able to predict glucose levels and suspend insulin delivery if a patient’s CGM is not functioning properly or his/her pump is unable to receive the CGM signal. It’s recommended your patient always uses the components of the pump system (pump, cartridges, CGM, and infusion sets) according to the applicable instructions for use and checks them regularly to make sure they are functioning as expected. Patients should always pay attention to their symptoms, actively monitor and manage glucose levels, and treat according to your recommendations.


* If glucose alerts and CGM readings do not match symptoms or expectations, use a blood glucose meter to make diabetes treatment decisions.
