    Jan 05, 2020 Risk for toxicity is least with less than 6.5 mg/kg/day for hydroxychloroquine and 3 mg/kg/day for chloroquine. Patients are at low risk during the first 5 years of treatment.

    Initially, its manufacturers recommended that hydroxychloroquine dosage be no higher than 6.5 mg/kg of ideal body weight to prevent retinopathy. 1,29,30 However, it has recently been demonstrated that real body weight is a better predictor of risk of retinopathy than ideal body weight when dosing hydroxychloroquine, perhaps because of the increasing variance of real body weight in our patient population. 26 This apparently resulted in overdosing of thin patients. Thus, the patient’s real weight is now recommended as the basis for calculating the daily dose per weight in kg. Doses ≥ 5 mg/kg/day real weight of hydroxychloroquine 2.3 mg/kg/day of chloroquine are associated with higher risk of toxicity.
