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. Can i take plaquenil and methotrexate together Hydroxychloroquine pulmonary toxicity The majority of cases of retinotoxicity have occurred in patients that have had a cumulative dose exceeding 1000g of hydroxychloriquine Plaquenil. This level is reached in about 7 years with the most common daily dose of Plaquenil, 400 mg/day 200 bid. The adult dose for active infection of malaria is a total dose of 2500 mg divided over 3 days for patients over 60 kg and for those less than 60 kg, 41.7 mg/kilogram of divided over 3 days. Give patients with amebiasis a 1 gram loading dose for two days followed by 500 mg of CQ phosphate for 2-3 weeks. Plaquenil-induced maculopathy is a form of retinal toxicity that is associated with long-term use of of the anti-inflammatory medication plaquenil. The drug-induced maculopathy is associated with the following risk factors Cumulative dose level of 1,000 grams of plaquenil; Patients with existing retinal or macular disease; Patients over the. 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 associated classic retinal toxicity is described as a bull’s eye maculopathy ring of depigmented retinal pigment epithelium that spares the foveal area. Differential diagnosis – juxtafoveal telangiectasia – FFA to rule out In a confirmed case of tamoxifen toxicity with visual complaints, the drug must be stopped. Since maculopathy is rare, routine screening is not needed with current low dose therapy 10-20mg/day.
