This class of medications modulates or suppresses the body’s immune system response so it cannot cause ongoing inflammation. Immunomodulators, which may take several months to begin working, are generally are used when aminosalicylates and corticosteroids haven’t been effective, or have been only partially effective.

These medications may be useful in reducing or eliminating the need for corticosteroids, and in maintaining remission in people who haven’t responded to other medications given for this purpose.

Examples:

• Azathioprine

• 6-mercaptopurine

• Cyclosporine

• Tacrolimus
