Gestational diabetes: 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 7 to 30 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 medications in their original containers with the pharmacy labels on.
• Talk with your diabetes educator for more travel suggestions.
