She suffered from Sjogren syndrome and inflammatory arthritis and was currently treated with prednisone and methotrexate. She was previously treated with hydroxychloroquine (Plaquenil) 200mg bid (6.5mg/kg) for 10 years, which was stopped one year prior to presentation. Chloroquine prophylaxis dosage Ocular safety of hydroxychloroquine Plaquenil help rx Plaquenil and bartonella A risk factor for Plaquenil hydroxychloroquine retinotoxicity is a daily dose that exceeds 5.0 mg of drug per kg of body weight. The tool on the right simply calculates this threshold based on a ppatient’s real body weight. It’s important to understand that the daily dose is only one risk factor for plaquenil retinotoxicity. Apr 20, 2011 Problems with Plaquenil Use 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. Abstract. Background The American Academy of Ophthalmology recommendations on screening for chloroquine CQ and hydroxychloroquine HCQ retinopathy are revised in light of new information about the prevalence of toxicity, risk factors, fundus distribution, and effectiveness of screening tools. Review of systems: Blurred vision, halos, dry eye, dry mouth, gastroesophageal reflux, joint pain Pupils: Reactive to light in each eye from 5 mm in the dark to 2 mm in the light. Extraocular movements: Full, both eyes (OU) Confrontation visual fields: Full OU Intra-ocular pressure The optic nerves appeared healthy with a 0.3 cup-to-disc ratio. Past Ocular History: None Medical History: Sjogren syndrome and inflammatory arthritis, supraventricular tachycardia, anxiety, depression, peptic ulcer disease Medications: prednisone, methotrexate, amitriptyline, ranitidine, estradiol, tizanidine, diltiazem, Restasis Allergies: codeine, droperidol Family History: heart disease, arthritis, cancer Social History: occasional alcohol but no tobacco or intravenous drug use.
