| Funny, isn't it, how different an insulin can work for different people? The clinical data from the labs states that humulog has an onset of 1/2 hour to 3/4 of an hour. I'm just stating the facts as they are printed. As for regular, I assume you mean Humulin R? The onset for which is 0.5 to 1 hour. It peaks anywhere from 2-4 hours. Also, regular is a rapid-acting insulin, not a short acting one (such as Toronto). You may have noticed that my post said that Humulog peaks at 45 mins, which is fast, faster than Novorapid, which is anywhere from an hour to 3. This may explain too why you find it to work faster than Novorapid. But you have to remember, all of these numbers are based on averages. Test a few people, average it out...and there you have your stock numbers. Probably what the Dr would tell you.
Anyway, like I said, I've only ever used NovoRapid, so all I can give you are numbers. It all comes down to a personal choice. |
