    what is the "real" cut off that people have used expired insulin? I have many bottles of novolog that have never been opened that expired March, 2012..... I feel sick throwing so much out.....

    any thoughts?

    Toss it. The insulin I have in my fridge now has expiration dates in 2014, so you can just imagine how old your insulin is.

    For other prescriptions, our pharmacist (or maybe doctor...?) has told us in the past that the"real" expiration date is generally about 12 months after the printed date. Have you checked with your pharmacist?

    Personally I would toss it I wouldn't take a chance with insulin after it is our kids lifeline. This is the one thing I would never ever use past the expiration date.

    I wouldn't hesitate to use it for 6 more months as long as it has been stored in a consistently cool location.

    Hi. I don't know about insulin, but with oral meds, they lose their potency by about 1/2 by the time they reach expiry (I work in pharmacy). So, just keep that in mind when adjusting dosage when you start using "in-date" insulins again. To be safe, I would have your pharmacist contact drug company to ask about toxicity of expired insulin (whether it is or not). For example, acetaminophen (if I remember correctly) is somewhat toxic when expired. Better safe than sorry.

    It's not like they lose their potency by 1/2 on the date of expiration. It happens (slowly) over time.

    I would have used it too, to be honest.

    If you have a copy of "Type 1..." by Ragnar Hanas there is some information regarding storage of insulin in Chapter 13.

    I looked up one of the studies that he annotated: http://care.diabetesjournals.org/content/26/9/2665.full

    Some information from the above link that I found interesting:

    "At expiry, regulatory requirements state that the insulin product must retain at least 95% of its labeled potency."

    "At room temperature, the degradation of insulin is an approximately linear function. At elevated temperatures, insulin loses chemical potency, which is accelerated as the temperature increases. For example, at room temperature (77?F), insulin will lose <1.0% of its potency over 30 days, or <0.03% potency lost per day. In contrast, insulin stored in a refrigerator will lose <0.1% of its potency over 30 days (Lilly Research Laboratories, data on file)."

    "In conclusion, the recommended in-use period for insulin is based primarily on a number of factors and regulatory requirements, particularly relating to sterility of the product. Chemical and biological potency are not the determining factors in storage recommendations for insulins."
