I did a lot of international
travel during tx, carrying ribavarin, peginteron pens, Procrit and syringes. I carried the injectables in an insulated thermocool bag with ice packs. I always carried my meds on, would not dare place them in checked bags both because of the risk of losing them and the risk of breakage. At security I would advise what I was carrying and ask that the bag be examined by hand. I travelled in Europe, Mexico and the Caribbean without incident.
