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. Hydroxychloroquin sulphate Does plaquenil reduce inflammation CONCLUSIONS The mortality rate in patients with acute chloroquine poisoning, including those patients sick enough to be referred to a specialty unit such as ours, can be limited to or = 10%. This finding appears to be true even in patients with massive ingestions. Hydroxychloroquine and Chloroquine Toxicity The mechanism of CQ and HCQ toxicity is not well understood. High experimental doses have acute effects on the metabolism of retinal cells, but it is not clear how these short-term metabolic effects relate to the slow and chronic damage that characterizes the clinical state of toxicity. Chloroquine CQ and hydroxychloroquine HCQ are anti‐rheumatic medications frequently used in the treatment of connective tissue disorders. We present the case of a 45‐year‐old woman with CQ‐induced cardiomyopathy leading to severe heart failure. 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 acute attacks of malaria, chloroquine interrupts erythrocytic schizogony of the parasite. its ability to concentrate in parasitized erythrocytes may account for its selective toxicity against the erythrocytic stages of plasmodial infection.
