Here are a few tips for traveling with NovoLog®:

Bring extra supplies with you in case you are delayed, lose something, or decide to extend your trip.

If you are flying, make sure that you take your insulin and other diabetes medicines with you in your carry-on bag. Checked luggage could get lost or delayed! The Transportation Security Administration (TSA) allows you to bring diabetes supplies in your carry-on.

Your insulin needs to be kept at room temperature (below 86°F), so be sure not to store it in places like the trunk or glove box of a car, or checked baggage on a flight where the temperature may get too hot or cold.

It is a good idea to let TSA agents know before the security screening process begins that you have diabetes and are carrying supplies.
