Hydroxychloroquine, a medication originally developed to treat malaria, has emerged as a vital tool in managing autoimmune diseases such as rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). Classified as a disease-modifying antirheumatic drug (DMARD), it works by modulating the immune response, thereby reducing inflammation and preventing tissue damage caused by overactive immune activity.

The mechanism of action of Hydroxychloroquine 200 mg involves inhibiting the production of autoantibodies and interfering with the immune system’s signaling pathways. This helps to calm the immune system, reducing the aggressive attacks on the body’s tissues that characterize autoimmune disorders. Patients often experience a gradual improvement in symptoms, with noticeable effects typically taking **6 to 12 weeks** to manifest.

Hydroxychloroquine is generally well-tolerated, but like any medication, it carries potential side effects. Common side effects include mild gastrointestinal discomfort and skin rashes. More serious risks involve retinal damage with long-term use; thus, regular eye examinations are recommended for patients on this medication.

In addition to its role in treating autoimmune diseases, hydroxychloroquine has been investigated for its antiviral properties against various viruses. However, its efficacy against COVID-19 remains controversial and unproven.

Overall, hydroxychloroquine serves as an essential component in the management of autoimmune diseases, helping to fortify the immune system’s response while minimizing harmful inflammation. Patients should consult healthcare providers for personalized treatment plans and regular monitoring to ensure safety and effectiveness in their therapy.
