The main thing is to get the immune system under control. Of all the meds you listed the only one that does that is plaquinel and that is a very mild treatment. If your daughters symptoms are more severe or progressing then strong meds are needed. Prednisone is usually the first one tried because it often works and works quickly. Another med that is tolerated for long term use is often introduced and prednisone tapered if possible. There are many different drugs, or combinations of drugs to treat lupus.
Get a second opinion if the doctor is not being aggressive. It would be a good idea anyway. Where do you live? There are lupus support groups in many cities around the country and it is good to talk to others who have already fought the lupus war. It is not a hopeless fight.
