Hydroxychloroquine, commonly used to treat autoimmune diseases like rheumatoid arthritis and lupus, is dosed based on a patient’s weight to ensure safety and efficacy. The standard dosing guideline is 5 mg per kilogram of body weight per day. This dosage helps minimize the risk of retinal toxicity, a potential side effect of hydroxychloroquine.
For example, a person weighing 70 kg (about 154 lbs) would typically be prescribed 350 mg of hydroxychloroquine per day (70 kg x 5 mg/kg = 350 mg). It’s important to note that the maximum recommended daily dose is 400 mg. This means that even if the calculated dose based on weight exceeds 400 mg, the dose should not exceed this limit.
Hydroxychloroquine is usually taken as a single daily dose or split into two doses. It’s recommended to take the medication with food or a glass of milk to reduce stomach upset. For long-term use, regular eye exams are advised to monitor for any signs of retinopathy.
It’s crucial to follow the prescribing doctor’s instructions and not exceed the recommended dose. If you have any concerns or experience side effects, consult your healthcare provider immediately.
