MRCP2-2887

A 67-year-old man is seeking advice from a gastroenterology clinic before his upcoming trip to Brazil. He is concerned about the possibility of contracting travellers’ diarrhoea due to his medical history. The patient had a total colectomy with ileostomy formation 20 years ago for severe ulcerative colitis and is currently undergoing chemotherapy for small-cell lung cancer. He had previously experienced diarrhoea while travelling in the Caribbean, which complicated his ileostomy management for weeks. The patient’s only other medical history is hypertension treated with ramipril. What is the appropriate management to prevent travellers’ diarrhoea in this patient?
