Insulin is a protein dissolved in water, and like all proteins, it spoils over time if not refrigerated. While using unrefrigerated insulin is not immediately harmful, it will be less effective. This poses a serious risk of high blood glucose levels, which can be dangerous and challenging to manage. For individuals with type 1 diabetes, this can escalate to diabetic ketoacidosis, a potentially life-threatening condition. In the event of a power outage, there are several ways to keep insulin cold without electricity, including using an insulin cooler, ice packs, a medical-grade mini fridge, or dry ice.

Insulin can be stored at room temperature for up to 28 days
Insulin is a protein dissolved in water, and like all proteins, it spoils over time. It starts to break down and lose its properties, and may also get contaminated by bacteria. Insulin that has been exposed to extreme temperatures loses some effectiveness. The longer the exposure, the less effective it becomes, which can result in a loss of blood glucose control over time.
However, insulin can be stored at room temperature (below 80°F/26°C) for up to 28 days. In fact, new research shows that insulin can be stored unrefrigerated for months without losing its potency. For best results, insulin should be kept out of direct light and not allowed to get too cold (below freezing) or too hot (above 25°C/77°F).
Laboratory studies on prefilled syringes stored at 4°C to 23°C for up to 28 days showed no clinically relevant loss of insulin activity. However, two studies reported up to an 18% loss of insulin activity after one week to 28 days at 37°C.
If you need to keep insulin refrigerated or if the room temperature is too high, you can use an insulin cooler, ice packs, or a medical-grade mini insulin fridge.

Use an insulin cooler, ice packs, or a medical-grade mini fridge
If you need to keep your insulin refrigerated or if the room temperature is too high, there are a few options to keep it cool without electricity. Insulin coolers, ice packs, and medical-grade mini fridges are all effective solutions.
Insulin coolers, such as the Frio Large Cooling Wallet, can keep insulin cool for up to 45 hours without the need for refrigeration or electricity. This product is TSA-friendly and perfect for travel, requiring no special technology. To use it, simply soak the product in cold water, spread the crystals evenly through the pouch, towel dry, and place the medication in the activated pouch.
Another option is to use ice packs with a standard domestic refrigerator. This setup can keep insulin refrigerated for up to 48 hours. Ensure the freezer door remains closed as much as possible to preserve the cold. To avoid direct contact with ice, wrap the insulin in a cloth or place it inside a small box. Additionally, unplug your freezer to prevent accidental freezing when the power is restored.
For longer periods without electricity, a medical-grade mini insulin fridge is a good option. These fridges can be powered by propane, solar panels, or electric generators. Propane-powered refrigerators are commonly used by the Amish and Mennonite communities, providing a "disconnected" lifestyle. Solar panels and electric generators can also be used to recharge portable travel coolers, which can then be plugged into a car's cigarette lighter to maintain the desired temperature.

Avoid direct heat and sunlight, which reduce insulin's effectiveness
Insulin is a protein with a chemical structure that is easily "spoiled" if left in the heat. Heat can cause insulin to break down and lose its effectiveness. Insulin that has been exposed to bright sunlight sometimes turns a brownish colour and should not be used. Heat can also damage blood sugar monitors, insulin pumps, and other diabetes equipment.
Therefore, it is important to keep insulin away from direct heat and sunlight. Keep insulin stored indoors, in a cool, dry place. A standard domestic refrigerator can maintain its internal temperature for about four hours after losing power. If you need to keep insulin cool or the room temperature is too high, use an insulin cooler, ice packs, or a medical-grade mini insulin fridge.
If you are spending time in the sun, you may need to adjust your insulin dose. If you plan on being active in the sun, eat some extra carbohydrates and check your blood sugar levels beforehand. Keep something sugary on hand in case your blood sugar gets low.
If you are facing a power outage, a standard domestic refrigerator can maintain its internal temperature for about four hours after losing power. To extend this period, transfer your insulin to the freezer compartment, ensuring the freezer door remains closed as much as possible. This setup can keep your insulin refrigerated for up to 48 hours. However, it is crucial to prevent the insulin from freezing, as frozen insulin becomes ineffective and unsafe.
