Store insulin carefully

Insulin can lose its strength when kept in very hot temperatures. This includes a suitcase, backpack, or the glove compartment or trunk of a car. Use a travel case with an ice pack to keep insulin cool on hot days. But don't let the insulin freeze. Keep the insulin out of direct sunlight.

To make your insulin shots less painful, some healthcare providers advise that insulin be kept at room temperature. This means 68 to 72°F (20 to 22°C). At room temperature, insulin will stay good for about a month. Mark your calendar or set an alarm on your smartphone or computer so you know when the month has gone by. If you buy more than 1 insulin bottle at a time, store the extra bottles in the refrigerator. Before using a new bottle of insulin, always check its expiration date.

Keep your glucose testing strips at room temperature. Keep the cap on the container. This will help you get the best results. Keep them in the refrigerator if your room temperature is high.
