The inhaler needs to go into a quart bag, but DOES NOT COUNT in your one quart bag allowance. It can have it's own bag.
That said, I have yet to take mine out of the bottom of my pocketbook, and I have yet to have anyone blink an eye on it. I don't have the prescription box either. Same thing with my Epi-Pen, although I do have the script label on that, I had the pharmacist print out an extra.
