Hey all, Taking Bailey to Vet tomorrow to have her CBC rechecked to see if her platelets are back up to normal yet allowing me to home test her BG again. I had to reschedule her appointment due to family commitments and the time I normally feed her and give her insulin is the time I will be driving to the clinic. My question is How early/late can you give a dose without it being an overlap to the previous/future dose? Example: I give Bailey her morning dose of Lantus at about 4:50 am and her evening dose at 4:50 pm. Can I give her evening dose at 3:30pm? What is considered the safe "window" to dose? I know it doesn't have to be 12hrs apart to the exact minute just want to know how big a cushion I have. I didn't post this to the Lantus forum as I thought others might want to know the answer as well. The safe window of time might not be insulin specific? Thanks!
