    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.

    Plaquenil toxicity and lowering dosage Posted on August 28, 2015 by Luke — No Comments ↓ Plaquenil generic name hydroxychloroquine is one of the few medications that is regularly prescribed for Sjogren’s Syndrome, despite the fact that it has not been approved for SS by the FDA, so any use is off-label. Recommendations on Screening for Chloroquine and Hydroxychloroquine Retinopathy Retinal toxicity from chloroquine CQ and its analogue, hydroxychloroquine HCQ, has been recognized for many years. Chloroquine toxicity remains a problem in many parts of the world, but is seen less frequently in the United States where the drug largely has been. Although it is not possible to predict which patients will develop retinal toxicity, high-risk characteristics include the following daily dose greater than 400 mg or, in people of short stature, a daily dosage over 6.5 mg/kg ideal body weight or total cumulative dose of more than 1,000 g.

    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.

    In particular, chloroquine and hydroxychloroquine Plaquenil are two such medications, with the potential for retinal toxicity. Given that the retinal damage from these medications is largely irreversible, screening by a retinal specialist is critical to detect early retinal toxicity to try and limit the extent of visual loss. Aug 01, 2009 I just went to Winston-Salem to see a retinal specialist and am waiting for his reply--he did say it looked suspicious for toxicity. I just read an article by a lady who has experienced the same visual disturbances and was diagnosed with toxicity and has been off plaquenil 2 years but her eyes are still getting worse. Our data show that, although no hydroxychloroquine use is completely safe, the risk of retinal toxicity can be kept low with careful dosage adjustment and with shorter periods of use. However, the risk rises markedly with concurrent kidney disease, and the prevalence can exceed 50% with use above 5.0 mg/kg and with duration beyond 20 years.
