    ### Response:
    What is the treatment for microscopic polyangiitis (MPA)? MPA is treated with medications that suppress the immune system, which can lower an individual's resistance to infections. There are a variety of immune suppressing medications that are used in MPA; however, resources state that a steroid (usually prednisone) and a medication toxic to cells (usually starting with cyclophosphamide) are typically prescribed first.
