MRCP2-0737

A 56-year-old man comes to the Gastroenterology Clinic for a follow-up on his Crohn’s disease management. He was diagnosed when he was 16 years old and has had multiple flares of his disease, three of which required hospitalization. Initially, he was hesitant to start immunosuppressive medication to control his disease, but he has now changed his mind. The treatment options are discussed with him, and he decides to try monotherapy with azathioprine. He has a medical history of hypertension and gout, for which he takes amlodipine, ramipril, and allopurinol. What additional precautions should be taken before starting his treatment?
