Pattern of Retinopathy: Although the locus of toxic damage is parafoveal in many eyes, Asian patients often show an extramacular pattern of damage. Dose: We recommend a maximum daily HCQ use of 5.0 mg/kg real weight, which correlates better with risk than ideal weight.

OBJECTIVES To reassess the prevalence of and risk factors for hydroxychloroquine retinal toxicity and to determine dosage levels that facilitate safe use of the drug. Risk Factors. There are risk factors which may increase the likelihood of an individual in developing symptoms of Plaquenil toxicity 1. Dosage. The amount of drug the patient takes play a big role in increasing the risk for toxicity. Hydroxychloroquine and CQ retinopathy can progress even after the drugs are stopped, although the amount of progression and the risk to vision are functions of the severity of retinopathy at the time it is detected. 5,11 It seems doubtful that this late progression of damage after stopping the drug results from a continued reservoir of the drug, although clearance from the body does take many late progression may represent a gradual decompensation of cells that were injured. Risk of Toxicity: The risk of toxicity is dependent on daily dose and duration of use. There are no similar demographic data for CQ, but dose comparisons in older literature suggest using 2.3 mg/kg real weight.

Hydroxychloroquine blood levels predict retinopathy risk in lupus. Recommendations on Screening for Chloroquine and.. Eye screening for patients taking hydroxychloroquine Plaquenil®. New research finds that measuring blood levels of the medication hydroxychloroquine Plaquenil in people with lupus may be an effective way to predict risk of retinopathy, a disease which results in impaired or complete loss of vision. The study assessed 537 people with lupus and measured the levels of the drug present in their blood.
