    Rates and Predictors of Hydroxychloroquine Retinal Toxicity in Patients With Rheumatoid Arthritis and Systemic Lupus Erythematosus FREDERICK WOLFE1 AND MICHAEL F. MARMOR2 Objective. Hydroxychloroquine HCQ retinopathy is of concern because of the potential seriousness of visual loss and the medicolegal consequences of failure to detect toxicity. The risk of ocular toxicity increases with the cumulative hydroxychloroquine dose. The prevalence of retinopathy in those using the drug less than 10 years is less than 2%; in contrast, the prevalence in patients with more than 20 years of exposure is reported to be as high as 20%. 26 The exact incidence and prevalence of HCQ-induced retinal toxicity is unknown. As the incidence and prevalence data on collagen vascular disorders such as SLE and RA are variable, it is difficult to calculate the exact risk of retinal toxicity among patients with RA and SLE who are treated with HCQ.

    Results Real body weight predicted risk better than ideal body weight and was used for all calculations. The overall prevalence of hydroxychloroquine retinopathy was 7.5% but varied with daily consumption odds ratio, 5.67; 95% CI. The pattern of retinopathy caused by both HCQ and CQ is similar, but is much less common with HCQ. The earliest clinical changes in HCQ retinopathy are subtle changes at the macula, with pigmentary stippling and loss of the foveal reflex the typical light reflection seen on fundoscopy. Diagnosis Hydroxychloroquine-induced retinal toxicity Discussion. Chloroquine CQ and hydroxychloroquine Plaquenil HCQ have been used for many years, initially for the treatment of malaria but now more commonly for the treatment of inflammatory diseases such as rheumatoid arthritis and lupus 1.

    Plaquenil and sulfasalazine - Autoimmune Disorders - MedHelp Thanks for responding, I do appreciate your input. I ended up taking both the plaquenil and the sulfasalazine together and each one independent of one another to see which one was giving me the most side effects. It turned out that Plaquenil was the culprit. I was sooo sick from that drug that I absolutely had no choice but to discontinue it.
