Specifically, a daily dose of 6.5mg/kg based on ideal body weight and a cumulative dose of 1000g of hydroxychloroquine or 460g of chloroquine are both considered risk factors for retinal toxicity. Therefore, lower daily doses do not necessarily preclude patients from developing toxicity due to the risk from cumulative dosage.
