Once the diagnosis has been made, treatment is almost always required.The treatment used is called immunosuppression. This therapy uses a type of steroids, known as corticosteroids, to reduce (suppress) the ability of your immune system to fight infection.
It is usual to start treatment with a relatively high dose of steroids, usually prednisone or prednislone. When the inflammation is brought under control, the dose can be reduced. Usually other drugs are added to allow for a lower dose of steroids.
Another immunosuppressant, azathioprine, is most commonly used in combination with steroids. This drug is slower acting and has fewer side effects than steroids. Other drugs such as cyclosporin, tacrolimus, mycophenolate and D-penicillamine may also be considered.
