Introducing Control-IQ+:
tested, trusted, better
Control-IQ+ showcases an advancement in Tandem AID systems. This new algorithm is designed to predict and help prevent both hyperglycemia and hypoglycemia, ensuring that users maintain optimal glucose levels throughout the day and night. Some of the standout features of Control-IQ+ include:
AutoBolus: protects from highs and missed meal boluses
This helps users manage glucose levels more effectively to help prevent highs and cover missed meal boluses.

Continuous automation: more time in range
Control-IQ+ is continuously working without having to enter a “mode.” This allows a seamless transition between treatment ranges or targets to meet daily needs: Exercise Timer, programmed Sleep Schedules, and Temp Basal Rates.

Now cleared for type 2 diabetes
Both the Tandem Mobi system and t:slim X2 insulin pump powered by Control-IQ+ technology are now cleared for type 2 diabetes, providing people with that diagnosis more options to help effectively manage their condition.
The synergy of Dexcom G7 and Control-IQ+
The synergy of Dexcom G7 and Control-IQ+
Dexcom G7 is the perfect complement to the Tandem Control-IQ+ System. Dexcom G7 provides real-time glucose readings, which are crucial for predictive capabilities of Control-IQ+. Together, the Tandem Mobi system and the t:slim X2 insulin pump—powered by the Control-IQ+ algorithm—and Dexcom G7 can help to enhance your diabetes management:
- Seamless integration: Dexcom G7 seamlessly integrates with the Tandem Mobi System and t:slim X2 insulin pump, creating a comprehensive diabetes management solution.
- Real-time glucose monitoring: Dexcom G7 has the fastest warmup of all CGM systems† (just 30 minutes) and provides real-time glucose readings. The real-time data allows Control-IQ+ to make precise insulin adjustments, resulting in better glucose control.2
- Trusted partnership: Dexcom and Tandem have created life-changing3 diabetes management solutions with over a decade of collaboration.

*Important Safety Information: RX ONLY. Indicated for patients with type 1 diabetes, 2 years and older and for patients with type 2 diabetes, 18 years and older. BOXED WARNING: Control-IQ+ technology should not be used in anyone under the age of 2 years old with type 1 diabetes or under the age of 18 years old with type 2 diabetes. It should also not be used in patients who require less than a total daily insulin dose of 5 units of insulin per day or who weigh less than 20 pounds, as those are the required minimum values needed for Control-IQ+ to operate safely.
