azathioprine + prednisone + ustekinumab + vancomycin

This is a combination of four medications used in the treatment of inflammatory bowel diseases, particularly severe or complicated cases of Crohn's disease or ulcerative colitis. The combination includes:\n\n- **Azathioprine**: An immunosuppressant that reduces inflammation by suppressing the immune system\n- **Prednisone**: A corticosteroid that reduces inflammation\n- **Ustekinumab**: A monoclonal antibody that targets specific inflammatory pathways\n- **Vancomycin**: A glycopeptide antibiotic used to treat bacterial infections, particularly Clostridioides difficile infections that can complicate inflammatory bowel disease
