I have Diabetes 1 for more than 30 years. I am diagnosed with brittle diabetes, so my control is not always very good. But the last month have been strange. I use Novorapid insulin, which should be fast, but when I take it in the morning it does not react until around midday. Then I take the insulin for lunch and shortly after it rush down between 2,2 and 3,0. I have not changed the insulin dose, I eat the same as usual, I move the same as usual - everything as usual - just not my blood sugar. i also take Levemir morning and evening. Anybody who have experienced the same ?
 
The normal for novorapid insulin is a peak of 90 minutes to 2 hours and it should finish in 5 hours.

Are you rotating your injection sites as failure to do this could result in the insulin "pocketing"" and releasing later than normal
 
Are you also sure that your long acting insulin is at the right level and being administered properly?
 
Novo supposedly starts to work with 15-20 mins and peaks 90-120 mins after injecting, do some basal tests to rule out that it isn't your basal insulin that is causing your high morning bg levels, have a read of the following for an explanation on basal testing if your not sure on how to do this:

You may be experiencing dawn phenomenon alongside your morning dose...? I know for me, unless I inject the second I get out of bed and eat something straight after that, then I just rise and rise... My ratios for lunch are very different from my carb ratios at breakfast because of this. Have you talked through with your specialist? Perhaps ask them to run through ratios with you; and also perhaps ask about an accucheck expert meter, which you can pre-program different ratios for different times of day and it will adjust the recommendation of insulin dosage accordingly... Good luck.

Thank you for your comment - yes I am rotating the sites of injections, and in reality I use very small amounts of insulin - 3 units per meal - so I do not think this is the reason. probably something is wrong with my basal dose

Thanks for the link, - yes it is probably something wrong with my basal dose
 
I fast and did basal tests and bolus and corr tests, but found my sugar slipped out of control and very difficult to regain balance again. Have anyone experienced the same? Does skipping meals for testings result in such abnormal fluctuations?
 
I have been having similar problems & have been prescribed Metaformin in addition to insulin. It has don wonders for my blood sugar although there are a few other side effects that are not so pleasant.

I have had diabetes type 1 for 55 years. I have used Novorapid for a few years. For the last 6 weeks I have experienced exactly the same strange results as you have. Unfortunately I suffered 2 severe hypos when I tried to correct the high readings by injecting more insulin. A new doctor at the clinic only looked at the low readings and decided that it was my fault and my management was not good - after 55 years - and he wanted to change my whole regime. I thought that my meter might be giving false high readings so checked it against a different meter. It was okay. At the moment I am ignoring the high readings in late morning and find that by mid afternoon everything is normal. I think that there must be something wrong with the insulin. Doctors have not been helpful but I am going to talk to my local pharmacy to see if they know anything about it. I see that you posted 3 weeks ago. Have you found out anything since then?
 
I've had a couple of phials recently where the Novorapid seems to have had limited effect. When I have swapped out for a fresh phial, it has worked straight away. I don't know whether it is a manufacturing issue or a storage issue.

Either way, it is a little disconcerting.
