Travelers should carry loperamide for self-treatment of diarrhea and, if risk is moderate to high, an antibiotic to add if diarrhea is severe.

In Greece, if you are experiencing diarrhea, the most common over-the-counter (OTC) medication you will find at a local "Farmakeio" (pharmacy) is Loperamide, often sold under the brand name Imodium. Greek pharmacists are highly trained and can also recommend local alternatives like Anti-diarrol, which is a popular probiotic-based treatment specifically marketed for "traveler's diarrhea." For those needing to restore their electrolyte balance, Rizolyte or Almora Plus sachets are standard prescriptions for rehydration. In 2026, many Greek pharmacies also stock SmectiGo (diosmectite), which works by coating the intestinal wall to stop irritation. It is important to note that Greek pharmacies are easily identified by a large green cross and are the only places authorized to sell these medications; you will not find them in supermarkets. If your symptoms are accompanied by a high fever or blood, the pharmacist will likely advise you to see a doctor for a "Nifuroxazide" (Ercefuryl) prescription, which is an intestinal antibiotic used for more severe bacterial infections common in Mediterranean travel.
