So, earlier this month, I was given the opportunity to trial the Asante Snap insulin pump. While, I found through the two pump bodies that I went through, that it was a very nice pump to use and very simple, the one thing about it is that, currently, it is a Humalog cartridge pump only. I am a Novolog user, but I had been told by several different people that there really was no difference in the way the two insulins worked. While others, declared with certainty that there is, in fact, a difference.
I am one of those in the latter group. For the first couple of days, my sugars were great. I didn’t notice a difference at all, and if I did, it was actually better. Then, on day 3, it all went down hill…. or should I say.. up hill? I could not for the life of me control postprandial (after-meal) blood sugars. It would take two corrections to bring them down, and once I did, I would crash, and after I treated, I was right back up again. On days 4 and 5, the frustration was just beginning to be too much to handle. Although I had changed my site out 3 times during this short sprint, nothing I did worked. It was as if my body liked it to begin with, then just completely bugged out on me and was all like, “WTF? This isn’t my Novolog!”
So, I went back on my t:slim and filled it with Novolog. My blood sugars thanked me for it.
Since I had a couple of Humalog cartridges left over, I decided to use one with my next t:slim change-out and just pull the insulin from the pen cartridge. (You know, so they don’t go to waste and all.) Within hours, my sugars were cruising once again in the 300 range with no downward slope in sight, no matter the corrections I took.
So, here’s my hypothesis on it. Everyone, like snowflakes and fingerprints, is different. Some of us have chemical makeup in our bodies that play nice with Novolog, some that play nice with Humalog, some even go out of the box all together and prefer Apidra. And some people’s chemistry is just a party and dances with any type of insulin you give it. Mine is just partial to Novolog.
So while using the Snap pump was pretty neat and easy to use on a daily basis (hey, it really lives up to it’s name… it’s a “Snap” to use!), I simply can’t due to the Humalog-only bit. I do know they are working on getting a Novolog pen-cartridge accepting pump on to the market as well, so that will be great for all of you who are like me.
