Treatment focuses on controlling the inflammation and managing any underlying conditions that may be triggering the vasculitis.
A corticosteroid drug, such as prednisone, is the most common type of drug prescribed to control the inflammation associated with vasculitis.
Side effects of corticosteroids can be severe, especially if you take them for a long time. Possible side effects include weight gain, diabetes and weakened bones. If a corticosteroid is needed for long-term therapy, you'll likely receive the lowest dose possible.
Other medications may be prescribed with corticosteroids to control the inflammation so that the dosage of corticosteroids can be tapered more quickly. The medication used depends on the type of vasculitis that is present. These medications may include methotrexate (Trexall), azathioprine (Imuran, Azasan), mycophenolate (CellCept), cyclophosphamide, tocilizumab (Actemra) or rituximab (Rituxan).
The specific medications that you'll need depend on the type and severity of vasculitis you have, which organs are involved, and any other medical problems that you have.
Sometimes, vasculitis causes an aneurysm — a bulge or ballooning in the wall of a blood vessel. This bulge may need surgery to reduce the risk of it rupturing. Blocked arteries also may require surgical treatment to restore blood flow to the affected area.
