Can anyone out there tell me why 70/30 insulin only lasts 5 hrs. on a low carb diet? do you think it might have gone bad?

i think mine does that and it’s not bad. just opened it. ask ur endo though and ask if u need to up ur dose or something.

@Bobmac hi Bob, the 70 in your 70/30 is NPH. A very old formulation that lasts between 5 and 12 hours, depending. Your body needs background insulin 24 hours a day so if your 70/30 isn’t covering you, it’s time to have a discussion with your Endo and maybe try a better basal insulin like Lantus (or other) and a separate shot for meals.

If it’s bad it’ll probably not work at all but when in doubt, open a new one!
