From Newaygo, Michigan, USA:
What happens when insulin is "old?" Does it become poisonous or just lose its effectiveness? How long after the date on the bottle does this happen? How can a person tell?
Provided it's not frozen or cooked, then insulin lasts much longer than the shelf-life that manufacturers quote. However, it does gradually lose its potency which would be manifest by poorer control.
