Default Re: Insulin and Expiration Dates ?

This was an interesting topic. I wonder if the recommendation to disgard the insulin after opening after 30 days is just a marketing strategy. I have never used a vial of NPH N longer than 30 days. My girl has been just fine with her BG numbers. I just threw it away as recommended to prevent any harm. The information on the Q&A on canine diabetes was an eye opener in some points. I never heard of giving a dog only 1 injection of a NPH a day. I always was told and read it is to be 1 injection every 12 hours.
Very interesting.
