Basal Insulin

Scroll down to see a list of videos and posts about basal insulin.

Basal insulin forms the foundation of Type 1 diabetes treatment. To deliver this, either rapid-acting insulin is continuously delivered by a pump, or 1 to 2 daily injections of a long acting insulin analogue are used.

There are three injectable basal insulins. Although they can be used once daily in some people, in Type 1 diabetics they are typically injected twice-daily:

  • Lantus/Toujeo/Basaglar (insulin glargine)
  • Levemir (insulin detemir)

And there is a new once-daily long-acting basal that isn’t yet available in Australia:

  • Tresiba (insulin degludec)

Each has their pros and cons, and none will ever be perfect. This is partly because basal insulin isn’t steadily released by a non-diabetic, and is instead released in pulses every 5-6 minutes. To simulate the effect of these bursts of insulin, much higher levels of insulin are used, which causes all sorts of undesirable effects.

So which basal insulin and dosing strategy works best with Afrezza? I first tested Lantus and Levemir but have now started using the new ultra-long acting Tresiba.
