I think you were also asking about insulin. During Charlie my husband was on several different types of insulin and some of the pens were good for 28 days, some for only 14 after the first use. Our insurance had changed to a 90 day supply which was a large quantity of insulin on hand. I called the insurance company for information, and was informed that I could exchange any questionable pens (not refrigerated, not used) by calling them back and arranging for an even exchange with my local pharmacy after the electricity was back on. But that was back in 2004, possibly that has changed, also they may still be dealing with Texas, so contacting someone at the mail pharmacy may take some time. Good wishes, it's hard enough for us healthy souls to make it through, let alone someone with special needs.
