I brought it with me to Florida and Colorado and only Florida gave me a very hard time about it but someone finally approved it. Make sure you have a note from your dr and the enbrel in the box it comes with
I ask for a note from my RA doctor just in case I need it. I leave it in the pocket of my carry on case. I have been through security twice with no problems plus I have a knee replacement. I have a card for that.
I took my enbrel on a plane with no problems. When I began enbrel, they have me a little travel case (which broke immediately) but there was a card included which I still carry. I showed them the card at security and kept my enbrel in the packaging they send it in. I had no problems. Good luck!
