Hydroxychloroquine HCQ, sold under the brand name Plaquenil among others, is a medication used for the prevention and treatment of certain types of malaria. Specifically it is used for chloroquine-sensitive malaria. Other uses include treatment of rheumatoid arthritis, lupus, and porphyria cutanea tarda. It is taken by mouth. Hydroxychloroquine is commonly used alongside other disease-modifying drugs including methotrexate – especially for rheumatoid arthritis. However, some drugs can interact with hydroxychloroquine.
