Formula Used in Accutane Dose Calculation
The calculator uses standard medical dosing formulas:
1. Daily Dose Formula
2. Total Cumulative Dose Formula
3. Weekly Dose Formula
Example Calculation
Let’s assume:
- Weight = 60 kg
- Dose = 0.8 mg/kg
- Duration = 100 days
Step-by-step:
Daily Dose = 60 × 0.8 = 48 mg/day
Weekly Dose = 48 × 7 = 336 mg/week
Total Dose = 48 × 100 = 4800 mg
