Decision-making The differential diagnosis for new onset non-ischemic cardiomyopathy in this patient included inflammatory cardiomyopathy, viral myocarditis, sarcoidosis, amyloidosis, hemochromatosis, Fabry's disease and HCQ toxicity
It is a very safe and effective drug but, Introduction
[3] Hydroxychloroquine (HCQ) is a less toxic metabolite of chloroquine and is Chloroquine toxicity remains a problem in many parts of the world, but is seen less frequently in the United States where the drug largely has been replaced by HCQ
Examples include hair loss, rash, itching, and eye-related side effects
Some diseases treated with Plaquenil are: Lupus, which causes fever, rashes, skin problems, and other symptoms
Correlated Changes in Retinal Thickness and Visuomotor Function in Asymptomatic Plaquenil Toxicity Patients We have previously shown that a 5-minute eye-movement test can capture a number of largely independent "oculometric" parameters of human visual/visuomotor function (Liston & Stone, 2014)
However, this medicine is not used to treat severe or complicated malaria
Hydroxychloroquine is used to treat discoid lupus erythematosus (DLE) or systemic lupus erythematosus (SLE or lupus)
(To learn more about retinal toxicity, see the "Plaquenil: Side effects explained" section above
Use this medicine for the full prescribed length of time, even if your symptoms quickly improve
AAO recommendations published in 2016 suggested that daily dosage of hydroxychloroquine should be less than 5
3 The toxicity would double by 10 years, resulting in a 20% prevalence after 20 years
For lupus and rheumatoid arthritis, a starting dose of 600 mg is common
, 2018), in part due to a more aggressive treatment approach to About Hydroxychloroquine (Plaquenil) Dose
Yet Plaquenil has side effects that may harm your eyes and vision in potentially serious and permanent ways
In 2020, hydroxychloroquine (and to a lesser extent chloroquine) also received attention as a possible treatment for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)
Autoimmune conditions occur when the body's immune system attacks healthy cells, causing vulnerability to infections
people who already have retinal disease
12 This suggests the need for repeating 10-2 VF testing after cessation of the medication
Hydroxychloroquine is the most commonly redness or other discoloration of the skin
unsteadiness, trembling, or other problems with muscle control or coordination
"But you can't even compare it to the only other things I have [to treat lupus]—prednisone, where 100 percent of people get side effects, or immunosuppressive drugs, [which] suppress the immune system, potentially causing infections, low blood Hydroxychloroquine is an antimalarial drug commonly used to treat rheumatoid arthritis (RA), lupus and other autoimmune diseases, either alone or in combination with one or more other medications
The risks and benefits of continued treatment with PLAQUENIL should be assessed for patients who develop these symptoms
However, the toxic dose is reported as 20 mg/kg with lethal doses suggested to be as low as 30 mg/kg [4]
It may help if The risk of hydroxychloroquine-related retinopathy associated with skin hyperpigmentation is unknown
Initially used as antimalarials, both drugs have now become mainstays in the management of rheumatic diseases principally systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA)
• Pediatric patients ≥ 31kg: 6
[ 2] When calculating the dose of hydroxychloroquine, the recommended dose of ≤ 5 mg/kg actual body weight significantly reduces the overall risk of disease
By Luanne Chubb, OD There are multiple reports of veno-arterial ECMO to successfully treat aminoquinoline toxicity [98,, , , ]

Hydroxychloroquine (Plaquenil ®) and its parent drug, chloroquine, are synthetic drugs originally developed to treat malaria
Indeed, the progress made in recent years in screening methods has shown the presence of signs of early-onset retinal toxicity and therefore has led to an increase in its prevalence
For malaria treatment, 1,600 mg may be given within the first 24 hours
The risk of retinal toxicity was initially believed to be less than 1% after long-term (or a cumulative dosage of 1,000mg)
Hydroxychloroquine (Plaquenil) is used in the treatment of rheumatoid arthritis, systemic lupus erythematosus, and other autoimmune and dermatological conditions
Other uses include treatment of rheumatoid arthritis, lupus, and porphyria cutanea tarda
