If the therapies already described are ineffective, more aggressive immunotherapy may be indicated. Therapy can take the form of plasma exchange or high-dose IVIg, with the potential for more long-term immunosuppression, usually with prednisone or azathioprine.

Prednisone (Rayos)

Prednisone is used as an immunosuppressant in the treatment of autoimmune disorders. The combination of corticosteroid therapy with azathioprine may be more effective than steroid monotherapy.

Azathioprine (Imuran, Azasan)

Azathioprine inhibits mitosis and cellular metabolism by antagonizing purine metabolism and inhibiting synthesis of DNA, RNA, and proteins. These effects may inhibit formation of immune cells, possibly reducing activity of immune system.
