Insulin Storage and Care

All insulin pens and bottles (vials) have expiration dates. Refrigerated, unopened insulin pens and vials are good until the expiration date. Do not use insulin after this date. Once insulin is opened, it should be thrown away at the appropriate time. The table below will help guide you.

CARING FOR YOUR INSULIN

  • If insulin is kept at room temperature, it must be less than 86° F (30° C). Those marked * must be stored at less than 77° F (25° C).

  • If insulin is kept in the refrigerator, it must be between 36-46° F (2.22-7.77° C).

  • Do not freeze insulin.

  • Keep insulin away from direct heat or sunlight.

  • Throw away the insulin if it is discolored, thick or has clumps, or suspended white particles.

  • Be sure to mix "cloudy" insulins by rolling gently. Pens can be "rocked" from end to end.

  • Opened insulin pens should be kept at room temperature.

  • Always have extra insulin on hand.
