Re: [IP] Humalog potency loss?
I just joined the list and haven't read through the archives, so please
forgive me if I'm rehashing an old beat-to-death topic...
I find it difficult to believe (in my case) that 'infusion site corruption'
is what causes the problem, since I don't change the infusion site at all.
I merely change the insulin in the reservoir and tubing. Same infusion
site, infusion set, tubing, and reservoir. No repriming of the set either,
just the tubing itself.
