    Retinal toxicity of hydroxychloroquine


    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.

    The risk of developing retinal toxicity has been found to be dependent on the daily HCQ dose and the duration of use. The risk of retinal toxicity is 1% for those who use HCQ for up to 5 years and 2% for those who use HCQ for 5–10 years, but it rises to almost 20% after 20 years of HCQ use. The prevalence of retinal toxicity was 36.2% among patients who used ≤200 mg HCQ per day and 8.3% among those who used 200 mg HCQ per day, and there was no significant association between daily HCQ dose and retinal toxicity P = 0.062. 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.

    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.

    Remove Toxic Heavy Metals from the Body in 5 - 7 Hours. The safe removal of heavy metals is becoming one of the modern world’s greatest health issues. Heavy metals surround us; chemtrails, vaccinations, air, water and food, pollution, living or working near a smelter or mine, dental fillings and of course, the kingpin of all, fluoridated water. Hydrofluosilicic acid, the chemical often used to fluoridate drinking water, is an industrial waste that contains lead, mercury, cadmium, arsenic, aluminum, benzene and radioactive waste material.
