    Retinal toxicity from plaquenil years after discontinued


    Chloroquine is now uncommonly used in favor of its derivative hydroxychloroquine. In the United States, hydroxychloroquine is most often used for its anti-inflammatory effects in rheumatology and dermatology.

    An example of advanced toxicity is presented here. A 68-year-old female with rheumatoid arthritis was treated with hydroxychloroquine 200 mg PO bid for almost five years. She complained of bilateral visual disturbances and discontinued the medication. She reported progressive symptoms for over one year following discontinuation. Hi there, I normally post on the arthritis board, and due to toxicity of the Plaquenil after 2 years, I have had to discontinue it, since I failed the visual field testing. Although I take Enbrel, and MTX, neither one work as well as the Plaquenil and the fatigue and joint pain have returned full force. At recommended doses, the risk of toxicity up to 5 years is under 1%, under 2% up to 10 years, and rises to almost 20% after 20 years. Patients who are receiving Plaquenil need to have a yearly ocular examination beginning at least within 5 years of starting therapy, including a dilated retinal examination, central visual field testing, and OCT scanning. The drug is usually discontinued at the earliest sign of macular damage since vision loss is usually permanent and can even progress.

    While early toxicity may be asymtomatic, patients with more advanced stage of toxicity may complain of color vision changes or paracentral scotomas. Its toxic effects on the retina are seen in the macula.

    Plaquenil induced retinal toxicity is reversible if detected early and plaquenil dosage altered or the medication discontinued. Even suspicious early plaquenil toxicity warrants communication with the patient’s treating physician, and meaningful coordination of care would include a report even if the findings are normal. A cumulative dose of 1000g of hydroxychloroquine or 460g of chloroquine was likely the largest risk factor, which was typically achieved after 5-7 years of a typical dosage 8, 10. However, there have been case reports of patients with hydroxychloroquine toxicity as early as 1.9 months after starting treatment 11. 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.

    Healthboards - Infectious Diseases - Lyme Disease Biaxin. Mta43782- Did he give you Plaquenil with the Biaxin? From what I have been told by my LLMD and from what I have read, Plaqenil helps to make the Biaxin a little more effective. Something about lowering the PH of the insides of the cells so the Biaxin can be taken up easier into the cell and actually do more impact to the culprit.

    Gluten free hydroxychloroquine Plaquenil? After sifting through all the possibilities - and then finally stopping the generic Plaquenil for a week, and restarting with brand name Plaquenil - my stomach problems vanished. So it appears that the pharmacy's switch to a different manufacturer of my generic plaquenil was the culprit afterall.
