The t:slim X2 Insulin Pump System

Up to 38% smaller than other insulin pumps.1

Compact, watertight, and rechargeable via a micro USB port, the t:slim X2™ insulin pump can integrate with Dexcom G6 continuous glucose monitor­ing (CGM).* When integrated with CGM, patients can use either Control‑IQ™ or Basal-IQ® technology.


A Stand-alone Insulin Pump

The t:slim X2 insulin pump can be used with or without CGM. When CGM is turned off, the Bolus and Options buttons are placed in the center of the screen for easy access.

Predictive Technology

Optional Control-IQ (advanced hybrid closed loop) or Basal-IQ (predictive low glucose suspend) technologies are designed to reduce and prevent lows before they happen.

Control-IQ Advanced Hybrid Closed Loop Technology

Control-IQ technology uses an algorithm to automatically adjust insulin in response to predicted glucose levels to help increase time in the American Diabetes Association-recommended target glucose range (70-180 mg/dL).

View study

Predictive technologies help deliver insulin, making it simpler to manage diabetes.

Control-IQ Technology

Control-IQ advanced hybrid closed-loop technology on the t:slim X2 insulin pump is designed to help increase time in range (70-180 mg/dL) using Dexcom G6 CGM values to predict glucose levels 30 minutes ahead and adjust insulin delivery accordingly; including delivery of automatic correction boluses as needed.

Advanced Hybrid Closed Loop

Control-IQ technology adjusts insulin delivery to help prevent highs and lows, while still allowing the user to manually bolus for meals.

Automatic Correction Bolus Delivery

The Control-IQ system on the t:slim X2 pump delivers automatic correction boluses, up to 60% once per hour to help prevent highs.

Exercise and Sleep Activities

Dedicated settings for Sleep and Exercise Activities adjust treatment values to better match different needs when activities are enabled.


Basal-IQ Technology

Basal-IQ technology helps reduce the frequency and duration of low-glucose events by using Dexcom G6 CGM values to predict glucose levels 30 minutes ahead and suspending insulin if they are expected to drop below 80 mg/dL, or if a CGM reading falls below 70 mg/dL.

Predictive Low Glucose Suspend (PLGS)

PLGS technology is particularly beneficial to patients who don’t always recognize when their glucose level is dropping.

Reduce Lows Without Rebound Highs

In studies, Basal-IQ technology reduced time spent below 70 mg/dL by 31% and demonstrated no rebound hyperglycemia.2

Simple Set-up

The Basal-IQ feature on the t:slim X2 insulin pump has no complicated settings to manage. It operates in the background without constant input or interaction.

Remote Software Updates

The t:slim X2 insulin pump is the first FDA-approved insulin pump capable of remote feature updates.** Using a personal computer, patients can keep their pump up to date with the latest technology during its warranty period. In‑warranty Tandem patients will receive no-cost software updates for t:slim X2 insulin pump through the end of 2020.


We offer a variety of infusion set options to give our Tandem pump users a choice of cannula materials, tubing lengths, insertion angles, and insertion techniques. Your patients also have access to supplementary instructional videos on the Tandem Diabetes Care patient website.

Responsible Use of Control-IQ Technology

Even with advanced systems such as the t:slim X2 insulin pump with Control-IQ technology, patients are still responsible for actively managing their diabetes. Control-IQ technology does not prevent all high and low blood glucose events. The system is designed to help reduce glucose variability, but it requires that patients accurately input information, such as meals and periods of sleep or exercise. Control-IQ technology will not function as intended unless all system components, including CGM, infusion sets and pump cartridges, are used as instructed. Importantly, the system cannot adjust insulin dosing if the pump is not receiving CGM readings. Since there are situations and emergencies that the system may not be capable of identifying or addressing, patients should always pay attention to their symptoms and treat accordingly.

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.

* CGM sold separately.
† As measured by CGM. 
‡ If glucose values are predicted to be above 180 mg/dL, Control-IQ technology calculates a correction bolus with a target of 110 mg/dL and delivers 60% of that value. It will do this up to once per hour as needed.
§ The t:connect application is compatible with the following meters: OneTouch Verio IQ, OneTouch UltraMini, OneTouch Ultra 2, FreeStyle Lite, FreeStyle Freedom Lite, ACCU-CHEK Aviva, ACCU-CHEK Compact Plus.
^ CGM data requires a CGM-enabled Tandem insulin pump.
** Additional feature updates are not currently available for the t:slim X2 pump with Basal-IQ or Control-IQ technology and are subject to future FDA approvals. A prescription and additional training may be required to access certain future software updates. Offer only available to customers who reside in the United States, who are in warranty at the time they update their pump and who purchased a t:slim X2 insulin pump on or before December 31, 2020. Tandem may discontinue select software and features over time at its discretion. This is a limited time offer and Tandem reserves the right to discontinue this program at its discretion.
