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. What are altered effects of hydroxychloroquine Does plaquenil cause kidney damage Can i take tramadol celebrex and hydroxychloroquine together Multifocal Electroretinopathy measures electrical responses of various cell types in the retina. It is thought that although the bull’s eye seen on ophthalmic exam represents a disruption of the pigmented part of the retina, it is the photoreceptors that are the targets of hydroxychloroquine toxicity. Plaquenil hydroxychloroquine sulfate, Sanofi-Aventis and the less-used chloroquine are antimalarial drugs with anti-inflammatory properties that are used for the management of a spectrum of inflammatory conditions. 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. 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.

As a result, all patients taking plaquenil should have an examination approximately every six months. The macula should be examined through a dilated pupil. The incidence of Plaquenil related macular problems increases when approaching a dose of 600 to 700 mg. per day. The average dose is 400 mg. per day. This is a very safe dose. Hydroxychloroquine Plaquenil is considered a disease-modifying anti-rheumatic drug DMARD. It can decrease the pain and swelling of arthritis. It may prevent joint damage and reduce the risk of long-term disability. Hydroxychloroquine is in a class of medications that was first used to prevent and treat malaria.
