From Tacoma, Washington, USA:

My 9 year old daughter has had Type 1 diabetes for 6 months. During the past two months, her blood sugar readings have been rising. A month ago, we threw out the bottle of NPH and opened a new one. Her readings dropped back down to the comfort level of below 200, and even 100. For the past 4 days the readings have be creeping back up and we are worried that her insulin may be going bad after 1 1/2 weeks. We keep it in the fridge and check the expiration dates. Has this happened before?


Insulin stored in the refrigerator should be good for longer than 1 1/2 weeks. Be careful that you are not freezing the insulin vials inadvertently. Also be sure to mix the vial of cloudy insulin well before drawing up the dose. If opening a vial with a new lot number fixes the problem, it could have been a problem with a particular lot of insulin or how the insulin was stored or transported.

If your insulin is good, it could be that this is when your child is starting to show a need for more insulin as the diabetes intensifies. See previous questions about the honeymoon period.
