paracetamol 250mg 5ml dose 15kg child mg/kg BNF
Paracetamol 250 mg/5 ml, 5 ml TDS for a 15 kg child
Short answer: YES, it is acceptable - but read the details below.
Dose Calculation
| Parameter | Value |
|---|---|
| Child's weight | 15 kg |
| Dose given | 5 ml = 250 mg per dose |
| Dose per kg | 250 ÷ 15 = 16.7 mg/kg/dose |
| Frequency | TDS = 3 times daily |
| Total daily dose | 750 mg/day = 50 mg/kg/day |
Is It Within Safe Range?
Standard oral paracetamol dose:
- Per dose: 10-15 mg/kg (commonly used range)
- Maximum single dose: up to 20 mg/kg loading in some protocols
- Maximum daily dose: 60 mg/kg/day (general), up to 75 mg/kg/day for post-operative pain (BNFC)
Your dose of 16.7 mg/kg/dose is at the upper end of the standard range but well within safe limits.
Your total daily dose of 50 mg/kg/day is well within the maximum of 60 mg/kg/day.
- Park's Textbook of Preventive Medicine confirms: paracetamol in children 10-15 mg/kg/dose, maximum 100 mg/kg/day
- NHS guidance for the 250 mg/5 ml formulation is for children aged 6 years and above - at 15 kg, the child's age matters
Age Consideration - IMPORTANT
The 250 mg/5 ml ("Six plus") formulation is intended for children 6 years and over per NHS/UK guidelines.
- A 15 kg child is typically around 2-3 years of age
- At this age, the 120 mg/5 ml suspension is the standard formulation
- For a 15 kg child aged ~2-3 years: correct dose would be 150-225 mg per dose (10-15 mg/kg x 15 kg)
- With 120 mg/5 ml: 6-9 ml per dose would be appropriate
However, if this is an older/smaller child (6+ years, 15 kg), the dose is fine.
Summary
| Check | Result |
|---|---|
| Dose per kg (16.7 mg/kg) | Safe - within range |
| Total daily dose (50 mg/kg/day) | Safe - below 60 mg/kg/day max |
| Formulation (250 mg/5 ml) for ~2-3 yr old | Caution - this formulation is usually for 6+ years; consider 120 mg/5 ml syrup |
| TDS frequency | Fine - 4 times daily is also acceptable if needed |
Bottom line: The dose is pharmacologically safe for a 15 kg child. If the child is indeed 6+ years and small for age, it is perfectly fine. If the child is a toddler (~2-3 years), consider switching to the 120 mg/5 ml suspension and giving 6-7.5 ml TDS instead, as that is the age-appropriate formulation.
Only 250mg/5ml available how much to give
If Only 250 mg/5 ml is Available for a 15 kg Child
Target dose: 10–15 mg/kg
| Target | Calculation | Volume |
|---|---|---|
| 10 mg/kg | 10 × 15 = 150 mg | 150 ÷ 250 × 5 = 3 ml |
| 12.5 mg/kg (mid) | 12.5 × 15 = 187.5 mg | = 3.75 ml |
| 15 mg/kg | 15 × 15 = 225 mg | 225 ÷ 250 × 5 = 4.5 ml |
Practical Recommendation
Give 3.5 to 4.5 ml per dose, TDS (or QID if needed)
- Easiest practical dose: 4 ml (= 200 mg = 13.3 mg/kg) - safe and effective
- If fever is high/not settling: 4.5 ml (= 225 mg = 15 mg/kg) - maximum standard dose
- Do NOT exceed 5 ml (250 mg) routinely for a 15 kg child as that gives 16.7 mg/kg - not dangerous but above the standard target
Daily Dose Check (4 ml TDS)
| Value | |
|---|---|
| Per dose | 200 mg (13.3 mg/kg) |
| TDS total | 600 mg/day (40 mg/kg/day) |
| Max allowed | 60 mg/kg/day = 900 mg/day |
| Status | Well within safe limits |
Simple instruction to give: Give 4 ml of 250 mg/5 ml paracetamol every 6-8 hours (TDS/QID). Do not exceed 4 doses in 24 hours.
