Here is a complete, evidence-based summary of paracetamol dosing for a 1-year-old child:
Paracetamol Dose for a 1-Year-Old Child
Weight-Based Dosing (Standard Approach)
| Parameter | Details |
|---|---|
| Dose | 10-15 mg/kg per dose |
| Frequency | Every 4-6 hours as needed |
| Max doses/day | 4 doses in 24 hours |
| Max daily dose | The lesser of 75 mg/kg/day or 4000 mg/day |
| Min interval | At least 4 hours between doses |
A typical 1-year-old weighs approximately 8-12 kg, so an individual dose would be roughly 80-180 mg.
Age/Suspension-Based Dosing (NHS Guidance)
For the standard infant liquid suspension (120 mg/5 mL):
| Age | Dose |
|---|---|
| 6-23 months (includes 1-year-olds) | 5 mL (= 120 mg) |
This can be given up to 4 times a day, with at least 4 hours between doses.
Route-Specific Dosing
| Route | Dose |
|---|---|
| Oral (PO) | 10-15 mg/kg every 4-6 hours |
| Rectal (PR, suppository) | 10-20 mg/kg every 4-6 hours |
| IV | 15 mg/kg every 4-6 hours (if <10 kg, specialist guidance needed) |
Important Safety Points
- Never exceed 4 doses in 24 hours.
- Dose by weight, not just age - a heavier 1-year-old needs more.
- In obese children, use adjusted body weight (not total body weight) to avoid toxicity.
- Hepatotoxicity is associated with overdose - paracetamol has a narrow safety margin if dosing instructions are not followed.
- For fever after vaccination at 2-3 months: special lower dosing applies; at 1 year, standard dosing is used.
- Always use the measuring syringe or spoon provided with the liquid formulation.
