    Plaquenil cumulative dose toxicity


    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.

    The risk of plaquenil-induced toxic maculopathy is associated with a cumulative dose level of 1,000 grams and it usually takes 5-7 years for patients on the standard dose of 250-400 milligrams per day to reach that level. Sep 15, 2014 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. Mar 15, 2019 If the maximum daily dosage recommendations are followed, the likelihood of toxicity from chloroquine or hydroxychloroquine is less than 1% the first five years of treatment. Corneal epithelial changes are usually reversible, but retinopathy caused by these agents are not.

    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).

    Doses ≥ 5 mg/kg/day real weight of hydroxychloroquine 2.3 mg/kg/day of chloroquine are associated with higher risk of toxicity. Doses lower than 5 mg/kg/day have low risk 1% for the first 5 years, and below 2% between 5-10 years of use. The longer you use. Apr 20, 2011 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. 2,3. The associated classic retinal toxicity is described as a bull’s eye maculopathy ring of depigmented retinal pigment epithelium that spares the foveal area. Sep 15, 2014 Factors that increase the risk of developing hydroxychloroquine associated retinal toxicity include daily dose, cumulative dose, renal or liver impairment, older age, and prior retinal disease. Specifically, a daily dose of 6.5mg/kg based on ideal body weight and a cumulative dose of 1000g of hydroxychloroquine or 460g of chloroquine are both considered risk factors for retinal toxicity.

    Recommendations on Screening for Chloroquine and. Baseline Examination. All patients beginning long-term HCQ or CQ therapy should have a baseline ophthalmologic examination within the first year of starting the drug to document any complicating ocular conditions and to establish a record of the fundus appearance and functional status.
