Abstract
Hydroxychloroquine (HCQ) is an antimalarial drug that has historically been used to treat and prevent malaria. However, its mechanism of action has not yet been fully elucidated. HCQ affects various cellular and molecular pathways through different mechanisms. HCQ has also been shown to be a disease‑improving agent for the treatment of rheumatic diseases, including systemic lupus erythematosus, antiphospholipid syndrome, rheumatoid arthritis and primary Sjögren's syndrome. Although generally considered safe, adverse reactions have been reported with the use of HCQ and clinicians should carefully monitor patients with rheumatism when prescribing these drugs. The purpose of the present review is to strengthen the clinical use of HCQ for autoimmune diseases while highlighting the adverse effects that may occur during treatment.
