Medication math should be transparent and double-checked. Hydroxychloroquine Dose Calculator shows the reference calculation built into this plugin, while leaving the prescribing decision where it belongs—with the clinician and current product guidance.

What this calculator does

Hydroxychloroquine Dose Calculator uses Weight and Your custom daily dose to calculate 5 mg/kg hydroxychloroquine weight-based maximum. Where supported, it also shows Custom dose and Custom / max so the primary result is easier to check. It follows the exact field flow and engine behavior in this plugin rather than describing a different calculator with the same name. Medication calculations are reference math, not prescriptions. Indication, formulation, route, kidney/liver function, interacting medicines, allergies, maximum doses, and clinician-selected regimens can change the correct dose.

How to use it

Enter or select Weight and Your custom daily dose. Confirm weight units, formulation/strength, route, and dose units before reading the result. If an entry is unknown, do not substitute a guess simply to obtain a number.

How the calculation works

Maximum daily hydroxychloroquine in this tool is actual body weight × 5 mg/kg/day. If you enter a custom dose, the calculator also shows that dose as a percentage of the weight-based maximum.

Example

Using the sample values prefilled in this calculator, the primary result is 350 mg/day (Maximum recommended daily dose by actual body weight), Custom dose is 400 mg/day, and Custom / max is 114.3%. This example demonstrates the plugin’s own calculation path; replace the sample inputs with verified values before interpreting a real result.

How to interpret the result

The primary number is a retinal-safety-oriented 5 mg/kg/day ceiling based on actual body weight. It is not a statement that every patient should receive that amount.

Limitations and notes

The 5 mg/kg actual-body-weight ceiling is a retinal-toxicity risk recommendation, not a complete prescribing dose for every disease. Duration, kidney disease, tamoxifen, eye screening, disease control, and practical tablet dosing matter; the prescriber may choose a different regimen.
