Apiretal (Paracetamol) Dose Calculator

Use weight-based dosing to estimate a single dose and maximum daily amount.

Child age (months, optional) If under 3 months, always contact a clinician before dosing.

Weight (kg)

Medicine concentration (mg/mL) Many Apiretal formulations are 100 mg/mL. Confirm your bottle label.

Target dose (mg/kg per dose) Typical paracetamol range: 10–15 mg/kg per dose.

Dosing interval (hours) Common interval is every 4–6 hours when needed.

Important: This tool is educational and does not replace medical advice. Always check the package insert and your pediatrician’s instructions, especially for infants, chronic illness, liver disease, dehydration, or if multiple medicines contain paracetamol/acetaminophen.

How this Apiretal calculator works

Apiretal is a brand of paracetamol (also called acetaminophen in some countries). Pediatric dosing is usually based on body weight, not age alone. This calculator estimates:

single dose in mg,
single dose in mL (based on concentration),
typical dose range (10–15 mg/kg),
and a conservative maximum in 24 hours.

Standard dosing reference

Typical paracetamol pediatric pattern

A common guidance range is 10–15 mg/kg per dose every 4–6 hours, with a daily limit around 60 mg/kg/day in many pediatric protocols. Local labels and medical advice can vary, so always prioritize your clinician and product insert.

Formula used

Single dose (mg) = weight (kg) × target dose (mg/kg)
Single dose (mL) = single dose (mg) ÷ concentration (mg/mL)
Daily maximum (mg) = min(60 × weight, 4000 mg)

Example

If a child weighs 18 kg, concentration is 100 mg/mL, and target is 15 mg/kg:

Single dose = 18 × 15 = 270 mg
Volume = 270 ÷ 100 = 2.7 mL
Daily cap (60 mg/kg) = 18 × 60 = 1080 mg/day

This helps you stay inside a safe total daily amount while spacing doses appropriately.

Common dosing mistakes to avoid

Using age-based guessing instead of measured weight.
Confusing mg and mL.
Not checking bottle concentration (different strengths exist).
Giving another cold/flu medicine that also contains paracetamol.
Dosing too frequently during the night without tracking total 24-hour intake.

When to call a doctor urgently

Infant younger than 3 months with fever.
Repeated vomiting, severe dehydration, breathing trouble, seizure, or unusual sleepiness.
Suspected overdose or uncertain amount taken.
Fever that persists beyond expected timeframe or worsens.

Frequently asked questions

Is this calculator only for Apiretal?

It works for any paracetamol liquid if you enter the correct concentration in mg/mL.

Can I use teaspoons?

Prefer an oral syringe for accuracy. Household teaspoons are often inaccurate.

What if the prescribed dose differs?

Follow your clinician’s prescription. Personalized advice always overrides a general calculator.
