There are hundreds of drugs with potential retinal toxicity—so many that the National Registry of Drug-Induced Ocular Side Effects doesn’t stratify them by incidence or effect, said Frederick W. “Rick” Fraunfelder, MD, director of the Registry and associate professor of ophthalmology at Oregon Health & Science University in Portland. Chloroquine chemoprophylaxis define Plaquenil vision changes Contraindications for plaquenil He pointed out that the goal of the AAO is not to stop using an excellent drug but to reduce the recommended dose and to screen for early abnormalities. Dr. Rosenbaum reviewed the guidelines from the American College of Rheumatology, which are generally nonspecific regarding exactly how hydroxychloroquine should be used. He showed evidence that. Because the most commonly prescribed dose of hydroxychloroquine is 400 mg/day, women are on average overdosed much more often than men are based on IBW or RBW, and HR is almost exclusively a problem of women. In this article, we present evidence that the 20 AAO guidelines warnings are valid. The most recent 2016 guidelines from the American Academy of Ophthalmology AAO recommend the dose of HCQ ≤5 mg/kg real body weight to minimize toxicity 1. According to these new guidelines, the risk of HCQ retinal toxicity is less than 1 % in the first year of therapy and less than 2 % up to 10 years of therapy. “It’s a pretty rare thing.” Nevertheless, he urged doctors to master the Academy’s new guidelines, because the effects from chloroquine and hydroxychloroquine, when they do occur, are severe and often irreversible. “Plaquenil toxicity isn’t even in the top 10, or the top 100” if you’re looking at incidence, he said.

Twenty-six per cent of the patients were on doses exceeding. Hydroxychloroquine usage in US patients, their experiences.. New Guidelines on Hydroxychloroquine Dosage - Where Are We.. The 2016 American Academy of Ophthalmology.. Nov 10, 2019 American Academy of Ophthalmology AAO 2016 guidelines recommend to use HCQ at dosages ≤5 mg/kg real body weight to minimize toxicity 1. Important risk factors for retinal toxicity are daily and cumulative dosage of HCQ, duration of treatment, patient age and concomitant renal or liver diseases 1. Vision loss typically is permanent, with little significant improvement, and may continue to progress even years after drug cessation. Previous Plaquenil Testing Guidelines In 2002, the American Academy of Ophthalmology AAO established ocular examination guidelines for screening patients on Plaquenil therapy. Dosage. The 2002 recommendations considered a daily dose at or below 6.5 mg/kg/day of hydroxychloroquine to be low-risk for subsequent toxicity. Hydroxychloroquine is dispensed in 200 mg tablets, so an “average” 70-kg patient using the common dose of 200 mg bid actually would be receiving a slight overdose according to this threshold.
