Hydroxychloroquine
Hydroxychloroquine is used for selected autoimmune conditions and malaria-related indications. Long-term exposure can damage the retina, so eye-screening plans matter. Listed uses include rheumatoid arthritis and systemic lupus erythematosus.
Key points
- Retinal toxicity risk depends on exposure and patient factors and may be irreversible.
- Hydroxychloroquine can prolong the QT interval, especially with other rhythm-affecting medicines.
- It is not a general antiviral treatment and should not be used for unsupported infections.
Listings are for comparison only; suitability and supply depend on indication, prescription, eye and interaction checks, and pharmacy review.
Important safety checks
Review eye disease, kidney or liver impairment, heart rhythm, low glucose, muscle weakness, psoriasis, pregnancy and all QT-prolonging medicines. Follow the recommended retinal-screening plan.
When to seek urgent care
Seek urgent help for sudden visual change, fainting, a new irregular heartbeat, seizure, severe low blood sugar, marked muscle weakness, facial swelling or breathing difficulty.
