If you use a Freestyle Libre 2 continuous glucose monitor and insulin pens to dose your insulin, you just got good news. Bigfoot Biomedical’s new smart pen cap got FDA approval.
The pen cap fits on most disposable insulin pens and uses glucose data from the Libre CGM to give you insulin dosing recommendations. Bigfoot Biomedical CEO Jeffrey Brewer says the new system is designed to help answer the question: “How much insulin would my doctor recommend I take right now?”
The app the pen runs off also has two hypoglycemia alarms and will alert you to a missed basal dose. Not available for direct purchase users will either get it from their doctor or with a prescription.

Nose crinkle. Have been of more than two minds with the libre. It is not often as accurate as blood. I even purchased a new contour next to make sure it wasn’t the problem with having results be 30-60 off. Now, I just add 20 or 30 to each sensor scan unless I feel I need to test more than the 4 times I already test. Even the libre finger stick test strips are about 20 off from the Contour ones. I’ve talked to Abbot often, drink what I feel is a good amount of water, have gained weight since starting this contraption, and all in all, the last 6 months are just not exactly what I was hoping for….there must be something wrong with my body. Many libre users say they have no issues at all with trusting results and I should just trust it. Finger sticks are old fashioned. Yet…will wait a bit longer to stop using this thing, I guess.
Kris, have you tried the Dexcom CGM? Most people find it more accurate than Freestyle. And thank you for the appreciation 😉
That one is more expensive..But, I may need to veer that direction if I want to keep using this kind of testing.
