Her rheumatologist instructed her to undergo a baseline ocular examination prior to initiating Plaquenil (hydroxychloroquine, Sanofi-Aventis) therapy. Toxic maculopathy associated with chloroquine use was first documented in the literature five decades ago.1 In the United States, Plaquenil––an analog to chloroquine––is used to treat a variety of conditions, including rheumatoid arthritis, lupus and several distinct inflammatory disorders. Although the incidence of macular toxicity is infrequent with Plaquenil use (at a dosage of 200mg or 400mg q.d.), its visual impact can be devastating. Can i take plaquenil at the same time as metformin Does plaquenil work on osteoarthritis Eye damage from plaquenil Hydroxychloroquine sulfate HCQ, Plaquenil is an analogue of chloroquine CQ, an antimalarial agent, used for the treatment of systemic lupus erythematosus, rheumatoid arthritis and other autoimmune disorders. Its use has been associated with severe retinal toxicity, requiring a discontinuation of therapy. 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. Although the incidence of macular toxicity is infrequent with Plaquenil use at a dosage of 200mg or 400mg q.d. its visual impact can be devastating. 2,3 The associated classic retinal toxicity is described as a bull’s eye maculopathy ring of depigmented retinal pigment epithelium that spares the foveal area. Initially, central visual acuity may be unaffected, but the patient may notice related paracentral scotomas that often interfere with reading. The associated classic retinal toxicity is described as a bull’s eye maculopathy (ring of depigmented retinal pigment epithelium that spares the foveal area).

Early Plaquenil Toxicity Detected without Bull’s Eye Maculopathy. 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 relatively rare, estimated at 1 percent after five years and rising with continued therapy. 3 However. Dec 04, 2014 The incidence of HCQ retinopathy is very low. In fact, HCQ is estimated at having a 0.5% incidence of retinal toxicity after 5 years of therapy.5,6 Retinal toxicity secondary to HCQ is irreversible and can continue to progress following cessation of therapy. Prompt screening and serial monitoring, with the utilization of imaging modalities, is paramount importance to early detection. H ydroxychloroquine HCQ; Plaquenil, Sanofi, Bridgewater, NJ is an antimalarial agent that is also commonly used as a treatment for a variety of rheumatologic and dermatologic conditions, such as rheumatoid arthritis and systemic lupus erythematosus. The most common side effect associated with its use is retinal toxicity, which may be irreversible.
