Storing insulin

    • You can keep bottles of insulin at room temperature if you use them up in 30 days.
    • Keep extra insulin in the refrigerator. Remember to let refrigerated insulin warm up for about 15 minutes before using it. Throw away all open bottles of insulin after 30 days.
    • If you use insulin pens, be aware that room temperature storage guidelines can vary from 10 to 42 days, depending on the insulin type. Check with your diabetes educator or pharmacist.
    • Look at the expiration date on each insulin bottle/pen before you use it. Throw out insulin if the expiration date has passed.
    • Avoid exposing insulin to direct sunlight or freezing temperatures.
    • Do not use insulin that is lumpy, sticks to the edges of the bottle/pen or looks discolored.

    Traveling with insulin

    • When you travel, keep your insulin with you. Do not leave it in a car or other vehicle.
    • It is a good idea to travel with extra supplies (insulin, syringes and test strips).
    • Regulations for airline travel may apply. Check with the airline before you fly.
      • Keep all medicines in their original containers with the pharmacy labels on.
      • Talk with your diabetes educator for more travel suggestions.
