The 3 day rule for insulin refers to the guideline that insulin vials or pens should be used within three days of being open or at room temperature. This ensures the effectiveness and potency of the insulin. After three days, any remaining insulin should be discarded to maintain blood sugar control and avoid ineffective doses. Always store new insulin in the refrigerator, and ensure open insulin is kept below 86°F (30°C) to prevent degradation. Check expiration dates before use for optimal safety and efficacy.
