Hydroxychloroquine Sulfate is used across several disease families, primarily infectious and autoimmune disorders.

Malaria: reduces parasite replication and clears blood-stage infection. Rheumatoid arthritis: alleviates joint inflammation and slows disease progression. Systemic lupus erythematosus: diminishes systemic immune activity and improves skin and organ manifestations.

Hydroxychloroquine Sulfate may cause a range of adverse reactions.

Common Side Effects: - Nausea or upset stomach. - Diarrhea or abdominal cramps. - Headache. - Skin rash or itching. - Visual disturbances such as blurred vision. - Mild dizziness.

Serious or Rare Side Effects: - Retinal toxicity leading to vision loss. - Cardiac arrhythmias, including QT prolongation. - Severe hypoglycaemia, especially in diabetic patients. - Hematologic abnormalities such as agranulocytosis. - Hepatotoxicity or liver enzyme elevation.

Before initiating therapy, clinicians should consider several safety measures.

Cardiac monitoring: assess baseline ECG and monitor QT interval. Retinal screening: perform ophthalmologic exam prior to use and annually thereafter. Blood glucose: monitor for hypoglycaemia, especially in patients on antidiabetic agents. Liver and kidney function: evaluate hepatic and renal parameters before and during treatment. Allergy check: avoid in individuals with known hypersensitivity to hydroxychloroquine or related compounds. Store at ambient temperature: keep in original packaging, protect from moisture and direct sunlight.

Hydroxychloroquine Sulfate can affect, and be affected by, several other medicines.

Major Interactions (Avoid): - Antacids containing aluminum or magnesium: decrease absorption of hydroxychloroquine. - QT‑prolonging agents (e.g., quinidine, azithromycin): increase risk of cardiac arrhythmias. - Insulin or oral hypoglycaemic drugs: potentiate hypoglycaemic effect. - Strong CYP2D6 inhibitors (e.g., fluoxetine): raise hydroxychloroquine plasma levels.

Moderate Interactions (Monitor Closely): - Digoxin: may increase serum digoxin concentrations. - Warfarin: potential alteration of anticoagulant effect. - Rifampicin: may reduce hydroxychloroquine exposure. - Azathioprine: additive bone‑marrow suppression risk.
