What is Novolog and how is it used?
Novolog is a fast-acting insulin used to manage blood sugar levels in people with type 1 and type 2 diabetes. It is typically administered subcutaneously, just before or after meals, to help control the spikes in blood glucose that occur post-eating. Because it acts quickly, it is essential for patients to time their doses properly in relation to their meals for effective management.
The active ingredient in Novolog is insulin aspart, which mimics the body’s natural insulin response. It is important for users to monitor their blood sugar levels regularly and adjust their Novolog dosage based on their carbohydrate intake and blood glucose readings to maintain optimal glycemic control.
How long can Novolog be out of the refrigerator?
Novolog can be kept at room temperature for up to 28 days after being opened, as long as it is stored away from direct sunlight and heat. This allows for easier administration for individuals who may find it inconvenient to inject refrigerated insulin. However, if Novolog has not been opened, it should remain in the refrigerator until needed.
If Novolog has been left out of the refrigerator for more than 28 days, it should not be used and should be disposed of appropriately. Inadequately stored insulin can lose its effectiveness, which may result in poor blood sugar control, potentially leading to dangerous health consequences.
What are the storage requirements for Novolog?
Novolog should be stored in the refrigerator at temperatures between 36°F and 46°F (2°C to 8°C) until it is first opened. Avoid freezing the insulin; if Novolog has been frozen, it should not be used. Once the vial or pen is opened, it can be stored at room temperature for a limited period, making it more convenient for daily injections.
It is also essential to store Novolog away from extreme temperatures, direct sunlight, and humidity. All insulin products should be kept in their original packaging until needed to protect them from light exposure and potential damage.
