Humalog is a type of insulin used by people with diabetes to manage their blood sugar levels. It is a fast-acting insulin that helps to regulate blood glucose quickly after injection. One question that often arises among those who use Humalog is whether or not it needs to be refrigerated. In this quick guide, we will explore the answer to this question and provide some additional information about handling and storing Humalog.
Understanding Humalog
Humalog, also known as insulin lispro, is a rapid-acting insulin that works by lowering blood sugar levels. It is typically injected just before a meal to help control the rise in blood glucose that occurs after eating. Humalog starts working within 15 minutes of injection and reaches its peak effectiveness within 1 to 2 hours. It remains active in the body for about 3 to 4 hours.
Humalog’s Storage Recommendations
In general, unopened vials and cartridges of Humalog should be stored in the refrigerator at a temperature of 36°F to 46°F (2°C to 8°C). However, it is important to note that Humalog can be stored at room temperature for up to 28 days once it has been opened. This means that if you are actively using Humalog on a daily basis, refrigeration may not be necessary.
Exceptions to Refrigeration
There are a few situations in which refrigeration may not be feasible or necessary for storing Humalog. For example, if you are traveling and do not have access to a refrigerator, you can safely store your opened Humalog vial or cartridge at room temperature, as long as you do not exceed 86°F (30°C). However, keep in mind that once Humalog has been refrigerated, it should not be exposed to high temperatures again.
Another exception to refrigeration is when using insulin pens. Insulin pens usually contain a cartridge of Humalog that is inserted into the pen device. A cartridge that is currently in use can be kept at room temperature for up to 28 days, similar to the recommendation for vials.
Proper Handling and Storage
Regardless of whether you choose to refrigerate your Humalog or keep it at room temperature, it is important to take certain precautions to ensure its effectiveness.
– Keep Humalog away from direct sunlight and sources of heat.
– Do not freeze Humalog, as this can damage its structure and make it less effective.
– Inspect the appearance of Humalog before use. It should be clear and colorless. Do not use it if you notice any particles or if the liquid appears discolored.
– Always check the expiration date on the packaging. Discard any Humalog that has expired.
– If you are unsure about the quality or storage conditions of your Humalog, it is best to consult with your healthcare provider or pharmacist.
Traveling with Humalog
When traveling with Humalog, whether it is domestically or internationally, it is important to plan ahead to ensure that your insulin remains safe and effective.
If you are traveling by car, it is generally safe to keep your Humalog at room temperature. However, avoid leaving it in a hot vehicle or exposing it to extreme temperatures for prolonged periods. If you are traveling by air, it is recommended to keep your insulin in your carry-on luggage, as the temperature in the cargo hold can vary and become too cold or too hot for optimal storage.
When traveling with refrigerated Humalog, you may use a cooling pack to keep it at the appropriate temperature. However, be careful not to allow direct contact between the cooling pack and the insulin, as this can cause freezing. Using an insulated bag or cooler can also be a helpful solution for transporting Humalog during travel.
In Conclusion
In summary, Humalog does not necessarily have to be refrigerated as long as it is stored properly. Unopened vials and cartridges should be kept in the refrigerator, while opened vials and cartridges can be stored at room temperature for up to 28 days. However, it is crucial to follow the recommended storage guidelines and ensure that Humalog is protected from extreme temperatures. If you have any doubts or concerns about the storage or handling of Humalog, it is always best to consult with your healthcare provider or pharmacist. Remember, proper storage of Humalog is essential to maintain its effectiveness and to help you effectively manage your diabetes.
