Can I travel with it? What about TSA?

Also asked: flying, TSA, airport, vacation, travel with needles, keep it cold on a plane Answer: Yes. Keep the medication in its original labeled packaging, carry a copy of your prescription, and pack it in your carry-on, not checked luggage — cargo holds get too hot and too cold. Use a small insulated bag with a cold pack.

TSA allows medically necessary liquids and syringes. Declare them at screening. [CONFIRM: do we issue travel letters on request?]
