Humalog vs. Apidra

Hi Everyone! My doc switched me from Apidra to Humalog a couple months ago because I was having too many lows. However, I'm finding that I can't go more than two days with Humalog in my pump without having stubborn highs for hours. Is this common with Humalog in a pump? Is there another option that I'm not aware of? My lows are better but now my a1c has gone from 6.2 to 7.2, roughly.

I use novolog and it has been pump stable in a tslim for as long as it takes for my cartridge to run out. With my current TDD, that is about 8-10 days depending on how carb wild I go. I find a vial will be refrigerator stable for about 6 weeks and then it will fail abruptly so I am starting to pitch it at week 5 to avoid the never-ending high as it goes north.
I have no experience with humolog, and aphedira is not usable in tslim microdelivey system as it causes occlusions.

The three rapid acting analog insulin formulations, Humalog, Novolog, and Apidra, have essentially the same performance characteristics. There can be variance, however, in person to person. I, for instance, will develop "pump bumps," raised red allergic reactions to Novolog insulin delivered via an infusion pump.

I believe that these insulins recommend changing sites and sets at 48 hours. I'm not sure of their rationale and most pumpers, including me, will push using a set/site to three or four days.

There is a lot more to the control equation than simply the insulin. Site absorption can degrade over the years with scar tissue. Different infusion sets can help or hinder good absorption.

I had site absorption problems two years ago after pumping for 25 years. I experimented with several different infusion sets to discover one that could deliver dependable site absorption. I also adopted using a loofa sponge on my abdomen each time I shower. Those two things solved the problem for me.
