    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.

    Testing for Toxicity Visual Fields Early drug toxicity can cause bilateral, relative paracentral scotomas4 Defects can be present BEFORE definitive signs are seen on fundus examination. A white-on-white 10-2 threshold visual field is recommended.19 • Want to pay close attention 2-6 degrees from fixation21 For years, eye doctors have relied on threshold visual field testing to detect functional vision changes with plaquenil use, rarely finding any signs of toxicity except in advanced cases where vision symptoms are already manifest. The American Academy of Ophthalmology has published guidelines for monitoring patients for Plaquenil toxicity. Some cases are difficult to detect, especially if other eye problems are present. Current testing for Plaquenil toxicity may include Visual field testing to evaluate for missing spots near the center of the vision.

    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.

    Early retinopathy has been defined as an acquired, persistent paracentral scotoma visualized on automated visual field testing without any observable fundus changes. 1 Reports have shown that the visual loss from HCQ toxicity is less likely to be reversible once fundus changes are present. 1,2,3 Although newer testing modalities, such as spectral domain-optical coherence tomography, fundus autofluorescenece, and multifocal electroretinogram, are now recommended as part of screening when. The main outcomes were toxicity as determined by characteristic visual field loss or retinal thinning and photoreceptor damage. They also examined risk factors and prevalence. The study findings revealed that when hydroxychloroquine was used at doses 5mg /kg, the risk of retinopathy was 1% in the first 5 yrs. 2% in 10 yrs. 20 % after 20 yrs. Visual field testing is non-covered as a screening test. CPT requires an interpretation of the results of this test. Usually this is a short narrative describing the reliability of

    Hi everyone, I am wondering if anyone has had a problem with fatigue while on Plaquenil. At first, I was nauseous for a week or so, which the dr. After the nausea went away it seemed like my pain got worse for a week or so, and then it gradually got better. I am also bothered with stomach cramps and mild diarrhea.

    HYDROXYCHLOROQUINE SULFATE Drug BNF content published. Annual screening is recommended in all patients who have taken hydroxychloroquine for greater than 5 years; Annual screening may be commenced before 5 years of treatment if additional risk factors for retinal toxicity exist, such as concomitant tamoxifen therapy, impaired renal function eGFR less than 60 mL/minute/1.73 m 2 or high-dose therapy greater than 5 mg/kg/day of hydroxychloroquine sulfate.
