The doctor will most probably prescribe some oral immunosuppressive drugs. They include cyclophosphamide and corticosteroids. Mostly, these two categories exist to empower the immune system by letting it produce necessary antibodies. These drugs also assist in reducing bleeding of lungs. In most cases, the treatment takes half a year or one full year. To speed up the process, patients may try plasmapheresis to get rid of the dangerous antibodies that remain in the blood. In rare cases, people turn to a kidney transplant, a rather risky and life-threatening surgery.
