    Yes, insulin can go bad. All medication should be discarded after the expiration date posted on the packaging has passed. Below is a link which includes a chart detailing the shelf life of various forms of insulin.

    Yes it can, but the expiration date varies based on a number of different factors. It depends on what type of insulin it is, the container it’s stored in, how it is used, and the instructions from each manufacturer. Once opened, insulin will last anywhere from about a month to a few days, depending on the factors above and whether or not it is refrigerated. An unopened container will last until the expiration date printed on it, usually about 1-2 years after the date purchased.
