Packing for an international trip often means triple-checking that you have your passport, wallet, and phone before you leave the house. But one essential item travelers often overlook-or mismanage-is their medication. Forgetting a travel pill case, packing it in checked luggage, or not following TSA rules can quickly turn a dream vacation into a stressful scramble. Even over-the-counter basics, like children's Tylenol or chewable Pepto-Bismol, can be surprisingly hard to find abroad, especially in countries where pharmacies stock different formulations or ban certain medications altogether.
