Hey DMF....this is a very tricky situations. My thought would be to get a second and possibly third opinion form DR's. See how they would treat your case and what medicines they would use. I would think to keep your lupus under check that you would need to be on some type of immunosuppressant and have frequent (every few weeks) blood work done to check your liver.
Have you tried or are you on Plaquenil?
