If you’re traveling by air, take care when packing your medications. Keep them in the original containers, in case you need to reach your pharmacist in a hurry. Have a note from your doctor with you that explains your condition and your need for the medication, along with a list of all of them. A list will be helpful should you get stuck and need to replace a medication, or if you and your bags are separated. Always pack your pills in your carry-on bag so that they’re accessible at all times. If you are on various MS therapies; your medication may require refrigeration; ice packs are a good temporary fix until you get to a fridge.
