Hydroxychloroquine Safe Dose and Maculopathy Risk Calculator

Calculates maximum safe hydroxychloroquine dose (≤5 mg/kg/day actual body weight), cumulative dose thresholds for retinal toxicity (>1000 g), and 5-year screening intervals based on ACR 2016 ophthalmology screening guidelines.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Calculates maximum safe hydroxychloroquine dose (≤5 mg/kg/day actual body weight), cumulative dose thresholds for retinal toxicity (>1000 g), and 5-year screening intervals based on ACR 2016 ophthalmology screening guidelines

Each component has a specific meaning:

  • ACR 2016 ophthalmology screening guidelines — The acr 2016 ophthalmology screening guidelines recorded for the scenario being assessed.

Note: Interpret the hcq dose safety result against the thresholds and context described above.

How to Use

Enter the ACR 2016 ophthalmology screening guidelines for the scenario you are assessing. Calculates maximum safe hydroxychloroquine dose (≤5 mg/kg/day actual body weight), cumulative dose thresholds for retinal toxicity (>1000 g), and 5-year screening intervals based on ACR 2016 ophthalmology screening guidelines. Use the hcq dose safety result to inform your calculation.
