Check your bloods again. There can be a lag of upto 20 minutes ago in results due to blood flow?
You may well have checked "OK" on the way down??
Hi, I am quite new to this also, having been diagnosed about 7 months ago, but in my limited experience I'd say taking both together is unlikely to be the problem. I often take Levemir with my Novorapid and the hospital said they are fine to take together. Check it out with your nurse if you're not sure.That's the first I've taken them at same time. Won't be doing that again! Taking the Levemir on its own never bothers me.
