Before I get to the subject of my post, I have been watching this forum for quite a while, learning what I could before switching from the Medtronic 670G to the Tandem/Dexcom 6. What an educational site! I have learned so much from the wisdom and experience of others. A special shout-out to Dennis, Joe, WearsHats, and wadawabbit. Your posts have saved me a lot time in making this transition. Thank you very much!
I just completed training for the new pump and CGM a few weeks ago. I have been using Humalog since I started pump therapy about 14 years ago. I have always changed the cartridge and inset site every 3 days as recommended. Never had a problem.
However, the training packet from Tandem states in the Overview section:
“A) Type of insulin - U100 only Novolog/NovoRapid/aspart (72 hrs.) / Humalog/lispro (48 hrs.)”
The Diabetes Educator said because I use Humalog I would need to change my cartridge and inset site every 2 days. With Novolog I could extend that to 3 days.
I don’t remember hearing that or reading that with using my previous pumps. So far with the Tandem using Humalog, I’ve been changing every 3 days like I have always done with my previous pumps. I have not encountered any problems yet. And I hope I never do as the health insurance won’t cover Novolog.
I would love to hear from Humalog users (whether they use a Tandem pump or not):
How often do you change sites?
If you go past 2 days, have you encountered any problems?
Any information you may have about Humalog that would be helpful here.
Thanks for your help. I’m still learning.
