    It is generally well tolerated, but retinopathy is a concern. Retinopathy is rare, but is sight threatening, generally irreversible and may progress even after cessation of therapy. Although a number of risk factors have been proposed (such as duration of therapy and cumulative dose), the many exceptions (e.g.

    The full-field ERGs may become abnormal in these cases Fig. 33. The more recent substitute for chloroquine, Plaquenil, can also have macular effects noticible by mfERg testing see later section on mfERGs. Vigabatrin, a pediatric seizure medication, can be toxic to the retina. Attenuation of full-field ERG b-wave amplitudes can detect toxicity. Mg/kg Hydroxychloroquine Plaquenil19 3 mg/kg Chloroquine Arlen With Plaquenil Plaquenil is manufactured in only a 200 mg tablet The typical dosage is either 200 or 400 mg per day 200 mg daily puts anyone under 68 pounds at risk1 400 mg of Plaquenil daily puts anyone under 135 pounds at a higher risk for toxicity Hydroxychloroquine should be used with extreme caution in patients with psoriasis or porphyria because it has been shown to precipitate severe attacks. Use hydroxychloroquine in patients with these conditions only if the potential benefit to the patient outweighs the possible risk.

    Novel technologies such as optical coherence tomography (OCT), fundus autofluorescence (FAF) and multifocal electroretinogram (mf ERG) may provide the earliest structural and functional evidence of toxicity in these stages. Retinopathy on low-dose HCQ, or no retinopathy after a very large cumulative dose of HCQ) highlight our limited understanding of the disease process.

  4. Because early toxicity changes can be revealed on SD-OCT, it is prudent to perform a baseline screening of patients taking Plaquenil. Multifocal ERG has the ability to detect early macular dysfunction, so it should be included as part of baseline screening. A maximum daily dose of Plaquenil of 5.0mg/kg real weight is recommended.

    Evaluation with electroretinogram ERG 5. Determine the frequency of surveillance examinations. For example, if a patient has taken 250 milligrams of plaquenil per day for three years, the cumualtive dose is 273,750 milligrams. This equals 273.75 grams of plaquenil and is below the 1,000 gram threshold for developing toxic maculopathy. Another. The most common tests to detect hydroxychloroquine toxicity have been visual acuity, visual fields Amsler grid, automated visual field, color vision testing, full-field electroretinography ERG, and multifocal electroretinography mfERG.6, 7 Because of the localized nature of the defects, mfERG seems to be better than the full-field ERG in. Cein angiography, full-field ERG, and electro-oculogram are not considered to be helpful.1-3 mfERG is a sensitive, objective, and reproducible test for detecting hydroxy-chloroquine toxicity. Several drugs taken in high doses or for long periods of time can cause retinal degeneration with pigmentary changes.

    Hydroxychloroquine Plaquenil Success, Reviews and Side. The hydroxychloroquine cost is variable and highly dependent on a variety of factors, such as a patient’s type of insurance, location, and more. According to The Rheumatologist, in 2017 the cost of 30 hydroxychloroquine tablets averaged around 2.65.
