    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.

    Upon the detection of the visual field defects, the hydroxychloroquine was stopped. She was taking hydroxychloroquine 5.0 mg/kg/day with a duration of 10 years with a cumulative dose of 1460g putting her at increased risk for hydroxychloroquine retinal toxicity. Abstract. Background The American Academy of Ophthalmology recommendations on screening for chloroquine CQ and hydroxychloroquine HCQ retinopathy are revised in light of new information about the prevalence of toxicity, risk factors, fundus distribution, and effectiveness of screening tools. A cumulative dose that increases the risk of retinal toxicity • 1000g total Hydroxychloroquine HCQ • 460 g total Chloroquine CQ Cumulative dose of 1000g HCQ is reached in 7 years with the daily dose of 400mg19 Cumulative dose of 460g CQ is reached in 5 years with the typical daily dose of 250mg19

    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.

The risk of retinal toxicity was initially believed to be less than 1% after long-term or a cumulative dosage of 1,000mg. 3 The toxicity would double by 10 years, resulting in a 20% prevalence after 20 years. 4 However, research now shows toxicity continues even after cessation of the drug. 5 Thus preventing and detecting early effects of.

    Sep 15, 2014 A new study of Wolke F and Marmor MF, published in Arthritis Care & Research, in 2010, on approximately 4000 unrelated patients with rheumatoid disorders in treatment with hydroxychloroquine found a higher prevalence of HCQ toxicity 6.8/1000 users, but the prevalence was dependent on the duration of use cumulative dose. 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. Nov 01, 2015 The incidence of retinal toxicity is associated with the cumulative dose of the drug, increasing significantly beyond 1,000 g of HCQ. 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.
