I switched from lantus to novolog and the doses are different, I then switched to the 70/30 novolin (relion brand from wal mart) as it was much cheaper and the dose once again changed, although I am type 2 and monitor my levels closely, all insulin brands work differently so be careful and consult Dr.
I did finally settle on the 70/30 mix, you can get the pens but it is much cheaper to just inject yourself, I get the needles that are the same size as the pens.....good luck, it took me awhile to figure this one out (along with Dr. of course)
No. Often the two medications are prescribed together (although not mixed). This question cannot be answered on the internet. You need to consult with your nurse-practicioner or primary care physician who manages your diabetic care and prescribed the Novalog.
