Calculate Dosage

Typical adult dose: 500-1000 mg
Every 4-6 hours
Standard maximum: 4000 mg/day

How it Works

Adults typically use a fixed dose per administration (e.g., 500 mg) with a max daily limit (e.g., 4000 mg). For children, dosage is often based on mg/kg or age ranges, with a max mg/kg/day. We compute dose per administration, daily total, and volume/count if applicable.

Inputs Explained

  • Patient Type: Adult or Child
  • Formulation: Tablet, syrup, suppository, or custom
  • Dose: Amount per administration in mg
  • Frequency: Times per day
  • Child Weight: Used for mg/kg calculations

Example

Child, 15 kg, Syrup 120 mg/5 mL, 10 mg/kg, 4×/day:

  • Dose = 15 kg × 10 mg/kg = 150 mg
  • Volume = 150 mg ÷ (120 mg/5 mL) = 6.25 mL
  • Daily Total = 150 mg × 4 = 600 mg

Tips & Notes

  • Never exceed the maximum daily dose
  • For children, use weight-based dosing when possible
  • Always follow product label and medical advice
  • Consult a healthcare professional for medical concerns
