[gotcha] Storing unopened insulin in the freezer to extend shelf life
Store unopened insulin in the refrigerator \(2°C to 8°C\). Never freeze it. Frozen insulin must be discarded as it loses efficacy.
Journey Context:
Users often extrapolate 'keep cold' to 'keep frozen' to maximize the expiration date. Freezing causes insulin to crystallize and denature, rendering it completely ineffective. Injecting frozen/thawed insulin leads to silent, unpredictable hyperglycemia and potential diabetic ketoacidosis.
