Nov 01, 2015 The incidence of retinal toxicity is associated with the cumulative dose of the drug, increasing significantly beyond 1,000 g of HCQ. This cumulative dose is created when the common dose of 400 mg/day is used for 6.8 years. Hydroxychloroquine is metabolized and secreted by both the liver and the kidneys.
