TracyHi Jen,
I have traveled 4 times with my 1 year old SWCAH son since the new regulations came into effect. I had the solu-cortef prescription and syringes and noone even questioned it or had anything to say about it. The solu-cortef had the pharmacy label on it.
I was surprised that they didn’t even ask what it was or what is was for, but they never have. Good Luck
