Hydroxychloroquine is a disease-modifying anti-rheumatic drug DMARD approved for adults with RA. It is often given in combination with methotrexate and sulfasalazine a treatment known as triple therapy, to help slow RA disease progression for patients who do not get relief from methotrexate therapy alone. Hydroxychloroquine is also a disease-modifying anti-rheumatic drug DMARD that has immunomodulatory and anti-inflammatory effects. The exact hydroxychloroquine mechanism of action is unclear, although it does work to interrupt the communication of immune system cells to decrease swelling, pain, and joint damage. 1, 2, 3, 5 [ It may be used in addition to nonsteroidal anti-inflammatory agents.] Lupus erythematosus, discoid (treatment) or Lupus erythematosus, systemic (treatment)—Hydroxychloroquine is indicated as a suppressant for chronic discoid and systemic lupus erythematosus . falciparum , originally seen only in Southeast Asia and South America, are now documented in all malarious areas except Central America west of the Canal Zone, the Middle East, and the Caribbean.

On average, patients with hydroxychloroquine ever use were taking the drug 55% of the observation time. Discontinuation of hydroxychloroquine for at least 1 year before censoring or the end of the observation period occurred in 32% of all patients with ever use. Hydroxychloroquine is classified as an anti-malarial drug. It is similar to chloroquine Aralen and is useful in treating several forms of malaria as well as lupus erythematosus and rheumatoid arthritis. Its mechanism of action is unknown.
