# Hydroxychloroquine Sulfate 200 mg ## SHORT DESCRIPTION Hydroxychloroquine Sulfate 200 mg is a prescription **antimalarial and disease-modifying antirheumatic drug (DMARD)**. It is primarily used to manage autoimmune and inflammatory conditions such as **rheumatoid arthritis, systemic lupus erythematosus (SLE), and discoid lupus erythematosus**. It may also be used for the treatment of certain susceptible malaria infections. ([nhs.uk][1]) ## KEY BENEFITS * Helps reduce inflammation associated with autoimmune diseases * Helps manage symptoms of **rheumatoid arthritis** * Helps control disease activity in **systemic and discoid lupus erythematosus** * May help reduce joint pain, swelling, and stiffness associated with inflammatory conditions * Has antimalarial activity against susceptible malaria parasites * Can provide long-term disease control when taken regularly as prescribed ([nhs.uk][1]) ## USES / INDICATIONS Hydroxychloroquine Sulfate 200 mg may be prescribed for: * Rheumatoid arthritis * Systemic lupus erythematosus (SLE) * Discoid lupus erythematosus * Juvenile idiopathic arthritis in appropriate patients * Certain skin conditions that are sensitive to sunlight * Treatment of uncomplicated malaria caused by susceptible parasites, where appropriate ([Medicines.org.uk][2]) **Important:** Hydroxychloroquine is not appropriate for every type of malaria because resistance patterns vary by location. ## HOW IT WORKS Hydroxychloroquine modifies immune-system activity and helps reduce abnormal inflammation in autoimmune diseases. This can decrease inflammation, swelling, pain, and other symptoms associated with conditions such as rheumatoid arthritis and lupus. Against malaria parasites, hydroxychloroquine interferes with processes necessary for parasite survival inside red blood cells. ([Medicines.org.uk][2]) The medicine does **not work immediately** for autoimmune conditions. It may take several weeks, and sometimes several months, to achieve its full therapeutic effect. ([nhs.uk][1]) ## DOSAGE & ADMINISTRATION * Take Hydroxychloroquine Sulfate 200 mg exactly as prescribed by your doctor. * Swallow the tablet whole with a **meal or a glass of milk** to help reduce stomach irritation. ([Medicines.org.uk][2]) * Do not crush or chew the tablet unless specifically instructed. * The dose and duration depend on the condition being treated, body weight, kidney function, age, and other individual factors. * For long-term autoimmune treatment, the prescribed dose should not be changed without medical advice. * Malaria treatment requires a different dosing schedule and should be determined by a healthcare professional. * If a dose is missed, take it when remembered unless it is nearly time for the next dose. **Do not double the next dose.** ([nhs.uk][1]) ### Important dosing note Long-term hydroxychloroquine dosing is carefully considered because the risk of retinal toxicity increases with excessive daily and cumulative exposure.
