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.
