Chloroquine base molecular weight Side effects to plaquenil Advanced hydroxychloroquine toxicity presents as a bullseye maculopathy. Since retinal toxicity is usually irreversible, early detection of retinal toxicity and cessation of the offending agent is the best treatment. Corneal toxicity presents as an intraepithelial deposition of the drug into the cornea, which rarely affects vision. Plaquenil is manufactured in only a 200 mg tablet The typical dosage is either 200 or 400 mg per day 200 mg daily puts anyone under 68 pounds at risk1 400 mg of Plaquenil daily puts anyone under 135 pounds at a higher risk for toxicity Therefore, 200mg of Plaquenil daily is going to be a safe dosage for virtually all adults13 Novel Image Analysis Platform May Detect Early Signs of Retinal Toxicity Secondary to Hydroxychloroquine Use. Ellipsoid zone mapping, a new image visualization/analysis platform on optical coherence tomography, may be an effective screening tool to identify subtle retinal changes indicative of toxicity from hydroxychloroquine treatment, Cleveland Clinic research indicates. Chloroquine is now uncommonly used in favor of its derivative hydroxychloroquine. This article focuses upon hydroxychloroquine retinopathy.
