View Full Version : Fast-Acting -- how long?

Even on insulin, my control is VERY shaky. I tested my blood about an hour ago, and it was 370. I have pretty bad insulin resistance, so I injected 15 units of Novolog out of sheer frustration (was around 200 when I woke up and took 5 corrective units) and went for a short walk (less than a mile -- to pick up my dog from the groomer). Now -- 360. WTH?? 15 units of insulin, one hour, plus mild physical activity, and NOTHING?

How fast IS fast-acting? I've been noticing that the shots I give myself during the day tend to not work, then hit me all at once in the afternoon.

*sigh* I'm beginning to think the pump might really be a good idea.

It sounds like you aren't using enough Lantus. 10 units is not very much, especially for someone who is insulin resistant.

you didn't say if you have a slow stomach, a form of neuropathy... i take humalog and it takes about an hour to 2 hours to start to bring my levels down... but if your blood sugar is high in the morning, you need to increase your lantus from the night before, not the novolog you take the time of you reading...

:stupid1:

It could also be poor absorption. Site selection is important.

I don't think I have a slow stomach -- my sugars rise immediately after eating anything, but the insulin (during high-resistance times) takes forever to work.

I think I'm going to up my Lantus tonight, see if that'll help.

If my BS are in the normal range 60 to 140 it takes about 5 minutes before mine starts to get lower. If I am around 200+ it will take me maybe 1/2 hour before it starts to lower.

Silly question here, but why do you think you are insulin resistant? It could just be that there is too little lantus so that every time you put in Rapid, it is doing the work of the Lantus and not touching the food.

Anyway, with the Lantus, many folks seem to start on a 50/50 bolus/basal regime and then tweak from there. Doing a fasting test is a good idea to see what your blood does when food and rapid isn't involved.

according to "think like a pancreas", insulin like novolog and humalog peak sharply about 60 minutes after injection... also, they are supposed to start 5 to 15 minutes after injecting, peak from 45 to 90 minutes after injecting and last about 3 to 4 hours... but this can differ depending on the injection site...

injecting inslun into the abdomen absorbs faster, then the arms a little slower than the abs, the legs a little slower than the arms and rear a little slower than the legs... some say that the newer insulins (novolog, humalog, lantus, detemir) don't really differ in their absorbtion rates from site to site...
