Patient Education

Hydroxychloroquine


Hydroxychloroquine is used to prevent and treat acute attacks of malaria. It is also used to treat discoid lupus erythematosus (DLE; a chronic inflammatory condition of the skin) or systemic lupus erythematosus (SLE; a chronic inflammatory condition of the body) and rheumatoid arthritis in patients whose symptoms have not improved with other treatments. Hydroxychloroquine is in a class of drugs called antimalarials. It works by killing the organisms that cause malaria. Hydroxychloroquine may work to treat rheumatoid arthritis and systemic lupus erythematosus by decreasing the activity of the immune system.
