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. The 2011 AAO guidelines stated that a cumulative dose of 1000 g increases the risk of retinopathy equating to 6.85 years of treatment at 400 mg, and 13.7 years of treatment at 200 mg. However, the conclusions drawn on the significance of the cumulative dose are inconsistent.
