I've been posting about IntraMuscular injections over the past weeks, experimenting with this technique for corrections. For anyone that's been interested, here's what I've found:
- About 2x faster in my body. I can get a nasty high (>200) back down in range in about 2 hours. Doing it just with my pump subQ it takes about 4 hours to get back down from a bad one like that.
- I can see it start to work on my Dexcom in about half the time too. 15-20 minutes and BG starts dropping. Via subQ its always 30-40 minutes before I see anything happen.
- Peaks in about half the time as well: 45-60 minutes. SubQ, I generally peak around 90 minutes.
- Oddly, however, seems to have a longer "tail" than half the subQ result. I get about 4.5 hours out of a subQ injection. Getting 3-3.5 out of IM injection. SOOOOOO... I'm finding I am going lower with IM than with the same amount of insulin subQ. Scratching my head on this one
- Side-benefit: My 200U reservoir is making it 3 days now instead of 2 because I'm direct injecting corrections when its convenient and easy to do so.
- Been using my thighs exclusively.
- Downside: Have to manage all IOB via smartphone app, can't use pump. Not as big a deal as you might think -- only doing IM to correct "bad" situations. Minor corrections (anything under 150 or so) I'm still doing subQ via pump.
All said, it's a technique that is working well for me in yet another tool for tight control, keeping that time "in range" greater, and the a1c lower.
