Yes, but there are preparations that you should make before setting off so that you save yourself unnecessary hassle on the journey. When going through any security checkpoint, it is advisable to have plenty of information about your medications and any additional equipment available. You can do this by having a letter from your doctor about your medication, and keeping all original labelled packaging to hand. It is sensible to take more medication than you will need during your trip, in case your luggage gets lost.
