From Riverside, California, USA:
Our two year old son uses Humalog and NPH. We have been told to discard the vials one month after opening. There is usually more than one-half a vial of each going into the trash every month. Luckily, we have insurance that pays for insulin, but this sure seems wasteful. Any suggestions?
This is the manufacturer's advice and, while I agree, it seems wasteful. Your insurance company would be unhappy to cover any problems arising from you failing to take heed.
[Editor's comment: Unfortunately, standard insulin is packaged in 10 ml vials, and insulin (NPH in particular) had a tendency to lose its potency after being opened for about 30 days. If you are concerned, a way around it might be to purchase cartridges (which are used for pens) containing 150 Units (five cartridges per package). However, your insurance company may not cover the increased cost involved. SS]
