    In Sjögren’s, Plaquenil is used to treat many symptoms of Sjögren’s including fatigue, joint symptoms of arthritis and arthralgias (joint pain), dry mouth and dry eyes. Similar to its use in systemic lupus erythematosus, many clinicians feel that it is useful in reducing general Sjögren’s “disease activity.” One of the reasons that physicians feel comfortable in prescribing Plaquenil is its low risk to benefit ratio.

    In a separate study designed to compare chronically treated patients with and without ophthalmoscopic evidence of toxicity, significant thinning of the inner, outer and full thickness retina was observed in patients with clinically apparent retinal toxicity, whereas only selective thinning of the inner retina was detected in the group without fundus changes. 13 Once again, RNFL thinning was absent in patients with chronic HCQ exposure and no fundus changes; however, the group with fundus. The American Academy of Ophthalmology has published several dosing and screening recommendations for hydroxychloroquine to avoid potential retinal toxicity, yet some patients still experience permanent vision loss resulting from hydroxychloroquine retinopathy due to improper dosing of the drug and improper screening. Once retinal toxicity from hydroxychloroquine occurs, it is thought that the retinal changes are permanent and the disease can progress even if hydroxychloroquine is stopped for 1 to 3 years. Newer techniques for evaluation of retinal disease have been developed and these techniques can detect retinal toxicity earlier.

    As with any medication, allergic reactions including skin rashes and non-allergic reactions can occur. This means that the side effects of Plaquenil are mild and infrequent compared with its potential benefits.

    In obvious toxicity, the nasal inner subfield showed more thinning than the temporal inner subfield at 12 months after drug cessation p = 0.018, 95 % CI −1 to −8 μm. Conclusions Once HCQ retinopathy is diagnosed and the medication is discontinued, structural retinal changes commonly occur. 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 Thinning of the photoreceptor layer, ellipsoid layer, outer nuclear layer, and RPE can be among the earliest signs of hydroxychloroquine toxicity. 4 These changes often occur in the parafoveal area, although they can be more peripheral in Asian patients.
