Chloroquine is now uncommonly used in favor of its derivative hydroxychloroquine. In the United States, hydroxychloroquine is most often used for its anti-inflammatory effects in rheumatology and dermatology. Using pei vs chloroquine How long does it take plaquenil to affect bones Based on new data, the authors have revised the Academy’s 2011 guidelines to make screening recommendations more concise and practical. Ophthalmologists play a vital role in educating both patients and prescribing physicians about the risk of toxicity associated with exposure to hydroxychloroquine HCQ and chloroquine CQ drugs. The AAO 2016 guidance suggested that the rates of HCQ retinopathy were higher than had previously been recognised.1 The recommended dosage per the AAO 2016 guidelines was calculated for the 2696 patients who provided their body weight, and compared with their actual, current HCQ dose. Twenty-six per cent of the patients were on doses exceeding. Three reports from the American Academy of Ophthalmology AAO in 2002, 2011, and 2016 have provided clinicians with evidence-based guidelines for screening patients on CQ/HCQ therapy. Baseline testing within the first year of starting therapy should include a dilated fundus exam to document pre-existing retinal pathology. While early toxicity may be asymtomatic, patients with more advanced stage of toxicity may complain of color vision changes or paracentral scotomas. Its toxic effects on the retina are seen in the macula. Aao 2016 plaquenil Hydroxychloroquine retinopathy Eye, Hydroxychloroquine usage in US patients, their experiences.

Hydroxychloroquine is a well-tolerated medication for various rheumatologic and dermatologic conditions. Its main side effects are gastrointestinal upset, skin rash, headache, and ocular toxicity1. Within the eye, hydroxychloroquine can adversely impact the cornea, ciliary body, and retina1 Oct 30, 2019 Daily hydroxychloroquine base doses 5 mg/kg actual body weight were associated with an ~10% risk of retinal toxicity within 10 years of treatment and an almost 40% risk after 20 years of therapy.
