No, it is not recommended to use Levemir (insulin detemir) or any other insulin after it has been frozen. Insulin is a delicate medication, and freezing can damage its molecular structure, making it ineffective. When insulin freezes, ice crystals can form, and this alters the insulin's composition, reducing its potency.
Storing insulin in a freezer is not an approved method, and it can lead to unpredictable and potentially dangerous effects on blood sugar levels if used after freezing. Insulin should always be stored in a refrigerator between 2°C to 8°C (36°F to 46°F) until its expiration date.
If insulin has been accidentally frozen, it should be discarded immediately, and a new vial or pen should be used. Using compromised insulin can lead to uncontrolled blood sugar levels, which can have serious health consequences.
Always ensure you store insulin according to the manufacturer's guidelines and consult your healthcare provider or pharmacist if you have any doubts or concerns about insulin storage and usage.
