Co Amoxiclav Pediatric Dose Calculator 2026
How to calculate pediatric dose per day of co amoxiclav? The daily dose relies on the child’s weight (mg/kg/day) and infection severity. This 2026 calculator gives you precise mL per dose using local Philippine suspension strengths, reducing medication errors and ensuring safe antibiotic use.

Why weight-based dosing matters for co-amoxiclav (2026 update)
Co-amoxiclav (amoxicillin/clavulanate) is a broad-spectrum antibiotic frequently prescribed in the Philippines for respiratory tract infections, acute otitis media, sinusitis, and dental abscesses. Incorrect dosing can lead to treatment failure or antimicrobial resistance. The 2026 Philippine clinical practice guidelines continue to emphasize weight-based dosing (mg/kg/day) using accurate suspensions. Our co amoxiclav pediatric dose calculator follows the latest pediatric infectious disease recommendations, ensuring parents and healthcare workers avoid underdosing or overdosing.
Exclusive: 2026 quick dosing checklist for caregivers
🇵🇭 2026 tip: In the Philippines, many co-amoxiclav brands (e.g., Co-AX, Augmentin) come with 70 mL or 100 mL bottles. Always double-check the final volume prescribed to avoid calculation errors.
Pediatric dose reference table (45 mg/kg/day, BID)

|---|---|---|---|---|
| 5 kg | 225 mg | 4.5 mL | 2.3 mL | 1.4 mL |
| 8 kg | 360 mg | 7.2 mL | 3.6 mL | 2.3 mL |
| 12 kg | 540 mg | 10.8 mL | 5.4 mL | 3.4 mL |
| 15 kg | 675 mg | 13.5 mL | 6.8 mL | 4.2 mL |
| 20 kg | 900 mg | 18.0 mL | 9.0 mL | 5.6 mL |
Note: Values rounded to nearest 0.1 mL. This table uses twice-daily dosing (BID). Always confirm with the doctor.
2026 Philippines treatment timeline & adherence guide
- Days 1–3: Symptom improvement expected (fever, ear pain). Use the calculator for precise start dose.
- Days 4–7: Continue full course; do not stop even if child feels better — prevents antimicrobial resistance.
- Beyond day 7: Most uncomplicated infections require 7–10 days; revisit MD if no improvement.
Exclusive insight: Co-amoxiclav contains clavulanic acid which can cause mild diarrhea; probiotic supplements (e.g., Saccharomyces boulardii) can be considered 2 hours apart from antibiotic — always ask your pediatrician.
How to calculate pediatric dose per day of co amoxiclav (step by step)
- Obtain weight (kg): Use a calibrated scale.
- Identify prescribed daily dose: Usually 25–45 mg/kg/day of amoxicillin component. Severe cases: up to 80 mg/kg/day (rare).
- Calculate total daily amoxicillin: Weight × mg/kg/day. Example: 12 kg × 45 = 540 mg/day.
- Choose suspension strength (mg per 5mL): e.g., 250mg/5mL → each mL contains 50 mg amoxicillin.
- Total daily volume (mL): Total daily amoxicillin ÷ (strength per mL). For 540 mg/day and 50 mg/mL → 10.8 mL/day.
- Divide by frequency: Twice daily → 10.8 ÷ 2 = 5.4 mL per dose. Use dosing syringe.
Our interactive co amoxiclav pediatric dose calculator automates this process, reducing arithmetic errors — especially for Filipino parents juggling multiple medications.
Frequently asked questions (2026)
Yes, but neonatal dosing may be different; always consult a pediatrician before administering co-amoxiclav to newborns.
It uses the standard amoxicillin component — most local brands (Co-AX, Clavamox, Augmentin) follow the same mg/5mL strengths, but verify the bottle label.
If vomiting occurs within 30 minutes, you may repeat the dose. If later, wait for next scheduled dose. Contact your doctor if vomiting persists.
No, co-amoxiclav is a penicillin derivative. Never give if your child has a known penicillin allergy — seek alternative antibiotics.
250mg/5mL (amoxicillin component) is the standard for children >3 months; 125mg/5mL is used for low-weight infants.
Store at 2–8°C (refrigerator) and discard after 7–10 days depending on brand instructions. Never freeze.
Antibiotics take 48–72 hours for full effect; if fever persists or worsens, consult your pediatrician for possible resistance or alternative diagnosis.
