Why prescribe the t:slim X2™ Pump?

Now with Basal-IQ™ Technology


Predictive technology you can feel good about

In the development of our products, we have conducted thousands of interviews with people with diabetes and healthcare providers. We know that by listening to the needs of both patients and providers, we have a better chance of delivering products that will help improve their lives.

Our latest product is the t:slim X2™ Insulin Pump with Basal-IQ™ Technology, 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. It is also simple to teach and learn.

"Being a person with 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 it suspended and protected me from lows."

Benefits of the t:slim X2 Insulin Pump

  • The only pump capable of remote software updates

    Eligible t:slim X2 Pump users in the United States with a prescription for the new Basal-IQ Technology will be able to download the feature to their existing pumps from home at no cost using personal computers.

  • #1-rated Customer Support3

    Our California-based support team is consistently ranked #1 by pump users in independent patient surveys.

  • Much smaller than Medtronic pumps4

    The t:slim X2 Insulin Pump is up to 38% smaller than other pumps, yet can hold up to 300 units of insulin.

  • Extremely durable

    The aluminum case is durable and light, and the touchscreen is made of high-grade, shatter-resistant glass. The t:slim X2 Insulin Pump is also watertight,§ so you don’t have to worry about it accidentally getting wet.

  • Rechargeable Battery

    The battery can conveniently be charged via USB port.

  • Can be used easily with or without Basal-IQ and CGM

    When advanced features are turned off, the t:slim X2 Insulin Pump removes the CGM chart from the screen and puts the Bolus and Options buttons front and center for easy access.

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.
† Dexcom G6 CGM sold separately. Transmitter can only be paired with one medical device (either a Dexcom receiver or t:slim X2 Pump) and one consumer device (phone or tablet) at the same time.
‡ A new prescription and additional training are required for this software update. t:slim X2 Insulin Pump must be in warranty to qualify.
§ Tested to a depth of 3 feet for 30 minutes (IPX7).
