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

- Malaria prophylaxis: prevents infection in individuals traveling to endemic regions. - Malaria treatment: clears parasitic infection during acute episodes. - Rheumatoid arthritis: reduces joint inflammation and slows disease progression. - Systemic lupus erythematosus: diminishes systemic inflammation and organ involvement.

Hydroxychloroquine may cause a range of adverse reactions, from mild to serious.

Common Side Effects: - Nausea: occasional stomach upset. - Headache: mild to moderate intensity. - Visual changes: blurred vision or difficulty focusing.

Serious or Rare Side Effects: - Retinopathy: progressive vision loss requiring ophthalmologic monitoring. - Cardiomyopathy: heart muscle dysfunction that can lead to arrhythmias. - Severe skin reactions: such as Stevens‑Johnson syndrome or toxic epidermal necrolysis.

Before initiating therapy, several safety considerations should be addressed.

- Retinal monitoring: schedule baseline and periodic eye exams. - Cardiac assessment: evaluate QT interval and cardiac history. - Blood glucose control: monitor for hypoglycemia, especially with diabetic medications. - Hepatic/renal function: adjust use if significant impairment exists. - Hypersensitivity: discontinue if allergic reaction occurs. - Store at below 25°C: keep in the original pack, protect from moisture.

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

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

Moderate Interactions (Monitor Closely): - Insulin or oral hypoglycemics: may potentiate hypoglycemia. - Digoxin: can increase serum digoxin concentrations.
