No, you should not use Levemir insulin or any other insulin after it has been exposed to freezing temperatures for an extended period. Insulin should be stored under controlled conditions to maintain its stability and effectiveness.
Freezing insulin can cause irreversible damage to the protein structure, which may render it ineffective in controlling blood sugar levels. When insulin is exposed to freezing temperatures, the molecules can denature and form aggregates, leading to reduced or even complete loss of its activity.
It's crucial to store insulin properly to ensure its efficacy and safety. The recommended storage temperature for most insulin types, including Levemir, is between 36°F to 46°F (2°C to 8°C). Insulin should not be frozen, and it should also be protected from direct sunlight and extreme heat.
If you accidentally expose your insulin to freezing temperatures, it is best to discard it and get a new, properly stored vial or pen. Using compromised insulin can result in inadequate blood sugar control, which may lead to serious health complications. Always follow the storage instructions provided by your healthcare provider and the manufacturer of your insulin product. If you have any doubts about the quality of your insulin, consult your healthcare professional for further guidance.
