This eye toxicity limits long-term use of the drugs. The risk of toxicity is low for individuals without complicating conditions during the first 5 years of treatment using less than 6.5 mg/kg/day of hydroxychloroquine or 3 mg/kg/day of chloroquine, and/or cumulative doses of less than 1000 gram and 460 gram (total dose), respectively. Why take chloroquine phosphate 500 mg Plaquenil and lupus nephritis Plaquenil guidelines for eye monitoring 2016 Importance Hydroxychloroquine sulfate is widely used for the long-term treatment of autoimmune conditions but can cause irreversible toxic retinopathy. Prior estimations of risk were low but were based largely on short-term users or severe retinal toxicity bull’s eye maculopathy. The risk may be much higher because retinopathy can be detected earlier when using more sensitive screening. The new guideline on screening for hydroxychloroquine and chloroquine retinopathy is written in response to evidence from the United States that shows that hydroxychloroquine retinopathy is more common than previously recognised. Implementation of the guideline’s recommendations will prevent iatrogenic visual loss. The new guideline also makes recommendations regarding the techniques and. Abstract 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. The earliest signs of toxicity include bilateral paracentral visual field changes (best detected with a red test object) and a subtle granular depigmentation of the paracentral RPE. Some physicians suggest that lean body weight is more accurate when calculating daily dosage.

A risk factor for Plaquenil hydroxychloroquine retinotoxicity is a daily dose that exceeds 5.0 mg of drug per kg of body weight. The tool on the right simply calculates this threshold based on a ppatient’s real body weight. It’s important to understand that the daily dose is only one risk factor for plaquenil retinotoxicity.

Hydroxychloroquine retinopathy It is known that some people who take hydroxychloroquine for more than five years and/or in high doses are at increased risk of damage to their retina, the light sensitive layer of cells at the back of the eye. This is known as retinal toxicity or retinopathy.
