    Plaquenil maculopathy cumulative dose


    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.

In this patient, the cumulative dose is 2,190,000 milligrams of plaquenil. This equals 2,190 grams of plaquenil and is above the 1,000 gram threshold for developing toxic maculopathy. The first patient may be screened every few years for toxic maculopathy while the second patient should be examined every six to twelve months. A cumulative dose of 1000g HCQ is reached in 7 years with a typical daily dose of 400 mg. In the same study, toxicity was not related to age, weight or daily dose but was related to duration of use and increased rapidly after 5 to 7 years; thus, it is important to be aware of the risk factors and use more effective protocols of screening on all the patients who exceed 5 years of exposure.

    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).

    This cumulative dose is created when the common dose of 400 mg/day is used for 6.8 years. Hydroxychloroquine is metabolized and secreted by both the liver and the kidneys. Therefore, disturbed renal or hepatic function might reduce HCQ clearance and increase the propensity for toxicity.
