I am type 2 insulin dependant, injecting humalog three times a day and lantis at night. following orders and doing everything right, I had a bad spell of consistantly running in the 200- 300+ blood count range. Until I just started new bottles of insulin which caused my numbers to be back in the 100's, which leaves me to beleive one of the insulins that I'm on, must of not been working for me. I keep them stored in the refigerator and all and they are not expired. I am just wandering if anyone else may have experianced a similar problem or this is common from time to time.. David

It's always hard to know exactly why you have a stretch where all your numbers run high. But bad insulin is definitely a possibility. Even though you keep them refrigerated, it's possible that one of the vials could have gone bad somewhere in processing or shipping.

Also, I think insulin can go bad if it gets too cold. (I'd have to double check that one.)

But the fact that your numbers returned to normal as soon as you started a new vial certainly makes you suspicious of a bad vial of insulin.

Did you change needles? I found when I was on insulin I needed the longer ones to get the insulin where it needed to go. I ran high with short ones. But other than that I personally do not know if insulin goes bad? Did you discuss this with your phrmacist?

only told my dr.. no change in needles though. all my past and present needles are 1/2 " and useing the same 50 unit type for lantis and 30 unit size for humalog.. I will call pharmacist though in case he may have heard of others.

It's possible the needle size is different on the 50 unit type syringe vs. the 30 unit syringe.

I use two different types of syringes as well; I use the BD 28 gauge, 1/2 inch (12.7 mm) 100 unit syringes for my Lantus and the 1/4 inch (8 mm) 50 unit syringes for my Novolin R.

When I first added Novolin R to my treatment, I was using the Novolin R Innolet with 6 mm pen needles. I recently switched to syringe and vial (HMO covers them and it's cheaper) I noticed that I have much tighter control since using the longer needle.

I switched to the 1/2 inch needle for the Lantus due to horrible bruising that was occurring with the larger dose of Lantus (38 units).

both of the boxes of syringes I use have the same size needles. And had no change in either as I always use the bigger ones for lantus and smaller for humalog. I take 45 units of lantis at night and mostly anywhere betweeen 10 and 15 units of humalog before breakfast, lunch , & supper.(humalog based on current reading + carbs I'm eating in meal)
