Hydroxychloroquine sulfate is indicated for several therapeutic purposes under physician guidance.

- Malaria prophylaxis and treatment - Management of systemic lupus erythematosus - Treatment of rheumatoid arthritis - Adjunct therapy for other autoimmune conditions - Combination use in certain infectious disease protocols

Hydroxychloroquine may cause a range of adverse reactions, which are generally classified by frequency and severity.

Common: - Nausea or upset stomach - Diarrhea or loose stools - Abdominal discomfort or pain - Mild skin rash or itching

Serious: - Retinal toxicity leading to vision changes - Cardiomyopathy or heart rhythm disturbances - Severe hypoglycemia, especially with antidiabetic drugs - Hemolysis in patients with glucose‑6‑phosphate dehydrogenase deficiency

Before initiating therapy, clinicians should evaluate several safety considerations.

- Obtain a baseline ophthalmologic examination and schedule regular follow‑up eye checks - Assess renal and hepatic function for possible dose adjustment - Screen for glucose‑6‑phosphate dehydrogenase (G6PD) deficiency - Monitor blood glucose levels in diabetic patients - Review cardiac history and consider ECG monitoring for QT prolongation risk - Discuss potential risks during pregnancy and lactation - Advise patients to avoid excessive sun exposure and use sunscreen

Hydroxychloroquine can interact with other medicines, influencing efficacy or safety.

Avoid: - Concurrent use of other QT‑prolonging agents such as quinidine or azithromycin - Antacids containing aluminum or magnesium that may reduce drug absorption

Use with caution: - Digoxin, because hydroxychloroquine may increase serum concentrations - Insulin or oral hypoglycemic agents, due to enhanced hypoglycemic effect - Cyclosporine, which may raise the risk of nephrotoxicity - Systemic corticosteroids, potentially augmenting immunosuppression
