    Plaquenil toxicity in the eye


    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.

    Plaquenil is a drug that is stored in high concentrations throughout the body and is very slowly eliminated from the body. It is attracted to the retinal pigmented epithelium in the back of the eye the retina. Although rare, Plaquenil can cause significant toxicity to the eye with prolonged use. May 12, 2016 Plaquenil can prove toxic to the retina, threatening the vision. Regular eye examinations are essential for those patients taking plaquenil because over time the retina can become damaged beyond repair. Regular medical monitoring is the only way to ensure that toxicity is not occurring. On examination, a telltale sign of hydroxychloroquine toxicity is a bilateral change in the retinal pigment epithelium of the macula that gives the commonly described appearance of a bull’s-eye. This is a late finding, however, and too late for screening to be useful.

    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).

    Unfortunately, despite their many benefits, both medications, chloroquine Aralen or its analogue, hydroxychloroquine Plaquenil, carry with them a very small risk of permanent vision loss. Eye screening by an ophthalmologist is important to help identify any damage to the eye at the earliest stage possible. Macular toxicity is related to the total cumulative dose rather than the daily dose. Regular eye screening, even in the absence of visual symptoms, is recommended to begin when either of these risk factors occurs. Toxicity from hydroxychloroquine may be seen in two distinct areas of the eye the cornea and the macula. If you are taking Plaquenil to treat an inflammatory condition or malaria, you should be aware of the side effects that may occur to your eyes and vision. Plaquenil hydroxychloroquine is in a class of drugs called disease-modifying anti-rheumatic drugs, which are used to decrease inflammation, pain and joint damage.

    Plaquenil & Calcium Absorbtion Arthritis Information Please has anyone had problems with the body absorbing calcium whilst taking Plaquenil. I have read that magnesium stearate in the Plaquenil, evidently binds to the calcium you are taking in via food or supplement and carries it out of your body.
