Irreversible retinopathy and ototoxicity can result from high daily doses 250 mg of chloroquine or HCQ that lead to cumulative total doses of more than 1 g of base per kilogram body weight 97–99. Retinopathy presumably is related to drug accumulation in melanin-rich tissues and can be avoided if the daily dose is 250 mg or less.

A study was undertaken to determine whether hydroxychloroquine also exerts a protective effect on survival. Most cases of chloroquine retinopathy have developed when a higher than currently recommended 3 mg/kg/day using lean body weight dose was used. 21 A daily dose exceeding 250 mg with a total cumulative dose between 100 and 300 g is customarily needed to produce toxicity. 22 One study showed a 19% incidence of chloroquine retinopathy in.
