Is it true or false that insulin should be frozen to prolong its effectiveness?

Insulin should not be frozen, as freezing can cause irreversible changes in its protein structure, leading to loss of effectiveness. Insulin is a protein hormone and is sensitive to temperature changes. When insulin is frozen, the formation of ice crystals may damage the insulin molecules, which ultimately reduces their ability to function properly in managing blood glucose levels.

For optimal storage, insulin must be kept in a refrigerator at temperatures between 36°F and 46°F (2°C to 8°C). If insulin needs to be taken out for use, it can be kept at room temperature for up to a certain number of days, depending on the specific formulation and the manufacturer’s guidelines. Maintaining proper storage conditions is essential for ensuring the medication remains effective when administered to patients. Therefore, stating that insulin should be frozen to prolong its effectiveness is false.
