Most importantly, you help support continued development of this site. The majority of cases of retinotoxicity have occurred in patients that have had a cumulative dose exceeding 1000g of hydroxychloriquine (Plaquenil). This level is reached in about 7 years with the most common daily dose of Plaquenil, 400 mg/day (200 bid). Chloroquine bafilomycin a1 conventional autophagy Hydroxychloroquine side effects high blood pressure Chloroquine phosphate and invertebrates Chloroquine price Let's dive in. Melton & Thomas describe the typical safe Plaquenil dosage this way The usual dosage is two 200mg tablets per day. This is generally a "safe" dose for patients having a lean body weight of at least 135 lbs. The generally-regarded safe dosage is 6.5mg/kg/qd, thus the 135 lb. safety threshold. There were no differences in hydroxychloroquine levels when both height and ideal body weight were compared across the different blood concentrations. This suggests that we are correctly dosing patients based on actual rather than ideal body weight not exceeding a dose of 400 mg per day and indicated that dosing based on height is unnecessary. If the 2016 dosage guidelines were applied, the extent of overdosing might be even greater, Dr. Koppikar said. Dr. Koppikar and Dr. Averns said they believe that one way to address HCQ overdosing is by giving clinicians a dosing chart to easily find the right dosage for a patient’s weight. It now solely uses real body weight (rather than ideal body weight) based on new recommendations from a 2014 study (1).

The current American Academy of Ophthalmology AAO guidelines, published in 2016, recommend a maximum daily hydroxychloroquine dose of ≤5.0 mg/kg of real 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.
