If you run out of medication in Europe, your best first step is to visit a local "Pharmacy" (Apotheke, Farmacia, or Pharmacie) with your original prescription or the medicine bottle showing your name. In many EU countries, pharmacists have some discretion for emergency refills, but most will require a local prescription. To get one, you can use a telemedicine app like Mobi Doctor or visit a local "Walk-in Clinic." If you are from the UK, your GHIC/EHIC card may help with the cost of a doctor's visit in public systems. Always bring a letter from your home doctor stating the generic name of the drug (e.g., "Ibuprofen" instead of "Advil"), as brand names differ between countries. For "controlled substances" like ADHD meds or strong painkillers, you will almost certainly need to see a local specialist and provide significant documentation. It is always safest to carry a double supply and a digital copy of your prescription when traveling abroad.
