It would be helpful if we know what medications your mother was taking in order to help you to know what else might be available for her. As Misslisa said, she might need to be put on a low dose of steroids (such as Prednisone).
Medications often are prescribed based upon which organ(s) are involved, and the severity of involvement. However, the commonly prescribed medications for treating Lupus include:
Nonsteroidal Anti-inflammatory Drugs (NSAIDs) – These drugs, such as aspirin and ibuprofen, are usually recommended for muscle and joint pain, and arthritis.
Acetaminophen – A mild analgesic used for pain, such as Tylenol.
Corticosteroids – Synthetically produced corticosteroids, such as Prednisone, are used to reduce inflammation and suppress activity of the immune system.
Antimalarials – These drugs, such as Plaquenil, are prescribed for skin and joint symptoms of lupus. It may take months before these drugs demonstrate a beneficial effect.
Immunomodulating Drugs – These drugs, such as Imuran and Cytoxan, act in a similar manner to the corticosteroid drugs in that they suppress inflammation and tend to suppress the immune system.
Biologic Drugs – These drugs include agents that block the production of specific antibodies, like those against DNA, or agents that act to suppress the manufacture of antibodies through other mechanisms.
Perhaps your mother can discuss these treatments with her doctor based upon her symptoms to see which, if any, would benefit her.
