Immunosuppressants are medications that quiet parts of the immune system to reduce intestinal inflammation in Crohn's disease and ulcerative colitis. They are prescribed and monitored by your gastroenterologist, not started from online lists.
Common examples (names vary)
- Azathioprine or 6-mercaptopurine (6-MP)
- Methotrexate
- Tacrolimus or cyclosporine in select cases
These differ from biologics, which target specific immune pathways. Many patients use immunomodulators with or instead of biologics depending on disease type and history.
Why monitoring matters
Regular blood work checks liver enzymes, blood counts, and sometimes drug levels. Report fever, sore throat, or unusual bruising promptly. Vaccination planning is important because the immune system is partially suppressed.
