Plaquenil is less toxic than chloroquine; however, long-term use of either drug can result in macular toxicity, leading to devastating irreversible vision loss. The mechanism of this toxicity is not clearly understood, though it is believed that the drug molecule binds to melanin in the retinal pigment epithelium (RPE). Is retinal toxicity from plaquenil reversible Will plaquenil help lupus when you have sjogrens Hydroxychloroquine dose for malaria Plaquenil dosage per weight Jan 05, 2020 Hydroxychloroquine is a well-tolerated medication for various rheumatologic and dermatologic conditions. Its main side effects are gastrointestinal upset, skin rash, headache, and ocular toxicity1. Within the eye, hydroxychloroquine can adversely impact the cornea, ciliary body, and retina1 The insert currently supplied with hydroxychloroquine states that patients should have an initial ophthalmological assessment and then regular assessm Jan 18, 2019 Hydroxychloroquine Plaquenil was originally used to treat malaria and is now used mostly to treat rheumatological and dermatological diseases. Its most frequent use now is for Rheumatoid Arthritis RA and Lupus and is often very effective in mitigating the joint and arthritic symptoms these diseases can cause. Binding of the drug to melanin in the RPE contributes to, or prolongs, its toxic effects. This leads to disruption and damage to the photoreceptors and outer nuclear and plexiform layer, sparing the foveal center and resulting in the “bull’s eye” appearance in the late stage of the disease.

What can Hydroxychloroquine Plaquenil do to my eyes?. Ocular safety of hydroxychloroquine sulfate Plaquenil.. Hydroxychloroquine HCQ, sold under the brand name Plaquenil among others, is a medication used for the prevention and treatment of certain types of malaria. Specifically it is used for chloroquine-sensitive malaria. Other uses include treatment of rheumatoid arthritis, lupus, and porphyria cutanea tarda. It is taken by mouth. Patients deprived of hydroxychloroquine because of ocular concerns are typically treated with far more toxic therapy to control disease activity, and thus may be needlessly exposed to harm. It is clear that the risk of retinopathy among patients receiving appropriate doses of hydroxychloroquine is vanishingly low, especially during the first 5–7 years of therapy, Hydroxychloroquine Plaquenil is considered a disease-modifying anti-rheumatic drug DMARD. It can decrease the pain and swelling of arthritis. It may prevent joint damage and reduce the risk of long-term disability. Hydroxychloroquine is in a class of medications that was first used to prevent and treat malaria.
