HQTOR 200 mg tablets contain hydroxychloroquine sulfate, an antimalarial and disease-modifying antirheumatic drug used to prevent and treat malaria and manage autoimmune disorders such as rheumatoid arthritis and systemic lupus erythematosus. Hydroxychloroquine works by disrupting the growth of parasites within red blood cells and modulating immune function. When used for malaria prophylaxis, HQTOR 200 mg is typically taken once weekly, starting two weeks before travel to an endemic area and continuing for four weeks after leaving. For autoimmune conditions, the dose varies but is often one tablet daily with food or milk to reduce stomach upset. Always follow your physician’s dosing instructions.

Common side effects of hydroxychloroquine include nausea, vomiting, diarrhea, abdominal pain, loss of appetite, headache and skin rash. These reactions usually resolve as your body adjusts. Serious side effects are rare but may include vision changes, hearing loss, muscle weakness, mood changes, irregular heartbeat or severe skin reactions. Regular eye examinations are recommended during long-term use because hydroxychloroquine can rarely cause retinal damage. Do not take HQTOR 200 mg if you have pre-existing retinal or visual field changes, severe liver or kidney disease, porphyria or sensitivity to 4-aminoquinoline compounds. Inform your doctor of all medications you are taking, as hydroxychloroquine may interact with antacids, cimetidine, digoxin, anticonvulsants and other drugs.

Hydroxychloroquine is a prescription medication that should be used under medical supervision. If you miss a dose for malaria prophylaxis, take it as soon as possible; if it is close to your next dose, skip the missed dose. Store HQTOR 200 mg tablets at room temperature away from moisture and out of reach of children. For comprehensive information or to purchase this medication, visit: HQTOR 200.
