Corticosteroids (oral or inhaled) are commonly used to treat pulmonary sarcoidosis; however, there is no consensus about when to start treatment, what dose of steroids to give and for how long. Immunosuppressive and cytotoxic agents (used in immunosuppressive doses) are used in addition to oral corticosteroids to treat multisystem and chronic sarcoidosis, or as steroid-sparing agents. We summarize the findings from two Cochrane systematic reviews that have examined the efficacy of corticosteroids and immunosuppressive and cytotoxic drugs in the treatment of pulmonary sarcoidosis. ⋯ Methotrexate had a steroid-sparing effect in one small study. Significant adverse events were associated with cyclosporine A, chloroquine and pentoxifylline. Evidence from randomized-controlled trials (RCTs) supporting the use of immunosuppressive and cytotoxic agents is limited.
