Hqheal 300 Tablet contains Hydroxychloroquine 300 mg, an antimalarial and immunomodulatory agent used primarily for the treatment and prevention of malaria, as well as autoimmune conditions such as rheumatoid arthritis and systemic lupus erythematosus. Hydroxychloroquine exerts its therapeutic effects by interfering with lysosomal activity and autophagy in immune cells, thereby reducing inflammation and modulating immune responses. It is indicated for acute and chronic malaria caused by Plasmodium species, and as a disease-modifying antirheumatic drug (DMARD) in autoimmune disorders. The tablet should be administered under medical supervision, with dosage tailored according to the specific condition and patient response. Common adverse effects include gastrointestinal disturbances, headache, dizziness, and potential retinal toxicity with long-term use, necessitating regular ophthalmologic monitoring. Caution is advised in patients with pre-existing retinal or visual field changes, hepatic or renal impairment, and those taking concomitant medications that may prolong the QT interval. Hqheal 300 Tablet is contraindicated in patients with hypersensitivity to hydroxychloroquine or related compounds. Proper adherence to prescribed dosage and periodic evaluation are essential to maximize therapeutic benefits while minimizing risks. This medication should be stored in a cool, dry place, away from direct sunlight and out of reach of children.
