  • Is Dexcom available at my pharmacy?

    You may have pharmacy coverage for Dexcom through your insurance, which would allow you to get supplies at your local pharmacy.

Here's how you can check if you have pharmacy benefits:

  • Will using Dexcom G6 change my daily diabetes management routine?

    If you’re already familiar with continuous glucose monitoring (CGM) systems, like the Dexcom G5 Mobile CGM System, the Dexcom G6 CGM System may or may not notably affect your day-to-day routine. However, you may benefit from the Dexcom G6 features that were designed for greater ease and convenience.

    Type 1 diabetes (T1D) is an autoimmune disease that occurs when the body’s own immune system mistakenly destroys insulin-producing cells in the pancreas.
