shouldnt be an issue right? even for carry on? got an rX and everything.
You'll be fine as long as you have your Rx. However, you have to put your syringes in your check-in bag. Have your Rx label on your syringes in the bag too.
I don't think the lack of a Rx would be the biggest problem. The problem would be bringing a sharp object on board the plane. Your best bet is to look up the carry-on restrictions on your airline's website. Good luck.
Never had a problem with syringes in carry-on. In fact, never even had them ask to see anything. I would just be sure to have labels where appropriate.
