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. Plaquenil help nausea Eye pain plaquenil Synthesis of chloroquine phosphate Plaquenil hydroxychloroquine is in a class of drugs called disease-modifying anti-rheumatic drugs, which are used to decrease inflammation, pain and joint damage. While today it is used to treat autoimmune conditions, such as rheumatoid arthritis and lupus, it was originally used as an anti-malaria drug. Hydroxychloroquine, sold under the brand name Plaquenil Sanofi-Aventis, is an antimalarial drug that has gained widespread use in treating various autoimmune diseases, including systemic lupus erythematosus and rheumatoid arthritis. 1 By some estimates, more than 150,000 patients are on long-term therapy with this medication in America alone. 2 Retinal toxicity associated with HCQ use is. Although it is considered rare, retinal toxicity from the intake of Plaquenil can be irreversible even if the drug is discontinued 2, 3. What is Plaquenil Toxicity? The toxicity resulting from the intake of Plaquenil is due to its affinity for melanin-containing structures in the body. “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.

New Plaquenil Guidelines. Plaquenil Toxicity - Symptoms, Treatment, Risk Factors.. Hydroxychloroquine Plaquenil Toxicity and.. Retinal toxicity of Plaquenil may manifest itself with subtle disturbances of the retinal pigment epithelium which may eventually lead to complete destruction of the macula in the form of bull’s-eye maculopathy. Several risk factors may increase the likelihood of retinal toxicity from Plaquenil such as. Therefore, there is considerable concern about the risk of ocular problems among patients treated with HCQ, and regular screening in accordance with standard guidelines is necessary, even in the absence of ocular symptoms. HCQ-induced ocular toxicity can occur in two distinct areas of the eye the cornea and the macula. It is recommended that hydroxychloroquine be discontinued if ocular toxicity is suspected and the patient should be closely observed given that retinal changes and visual disturbances may progress even after cessation of therapy.
