Medication Dosage & Syrup Calculator
Calculate precise single and daily medication dosage (mg/kg and liquid ml) based on body weight for children and adults.
About Calculator
The Medication Dosage Calculator helps determine the correct single and daily dose of liquid medications (syrups) based on patient body weight and the active substance concentration. It supports common pediatric medications like Paracetamol and Ibuprofen.
The formula is: Single dose (ml) = (Target dose in mg/kg × Patient weight in kg) / (Concentration in mg per ml). Daily dose is the single dose multiplied by the number of administrations per day.

Frequently Asked Questions (FAQ)
How is the dosage calculated?
Dosage (ml) = (mg/kg target dose × body weight) / (medication concentration in mg/ml). For example, for 15 mg/kg paracetamol at 120 mg/5 ml for a 20 kg child: (15 × 20) / (120/5) = 300 / 24 = 12.5 ml.
Can I use this for adult medications?
The calculator uses the same mg/kg formula, which works for adults too. However, adult medications often have fixed-dose regimens rather than weight-based dosing.
Should I rely solely on this calculator?
No. Always verify dosages against the official package leaflet and consult a healthcare professional. This tool is for informational estimation only.
