Augmentin Syrup Dose for Children in Pakistan: A Parent's Weight-Based Guide
Augmentin syrup is Pakistan's most prescribed paediatric antibiotic, but the three strengths (156, 312, 457 mg per 5 mL) confuse parents at 2 am. This guide gives the weight-based mL table for each strength, reconstitution and storage steps, side effects to watch, and when to call the paediatrician.

Quick Answer
Augmentin Syrup is dosed by your child's weight, not age. The standard dose for ear, throat, chest, or sinus infections in Pakistani children is 25 to 45 mg of amoxicillin per kg per day, split into two or three doses. For a 10 kg child on the 156 mg/5 mL strength, that is roughly 3 to 5 mL twice daily. The 312 mg/5 mL strength is the most common for older toddlers and primary-school kids. Shake the bottle before every dose, store in the fridge after mixing, and finish the full course (usually 5 to 7 days) even if your child feels better on day 2.
A 7 kg baby with an ear infection. A 22 kg seven-year-old with tonsillitis. Both walk out of the same Lahore clinic with a bottle of Augmentin Syrup and a hand-written "5 mL twice daily" on the strip. Six months later the same prescription gets reused for a sibling who is half the weight. This pattern, repeated in millions of Pakistani households, is the single biggest reason Augmentin works less reliably than it should: parents do not know how to read the strength on the bottle, and a one-size mL number is wrong half the time.
The dose is not complicated. It just requires the parent to look at three numbers: child's weight in kg, the strength written on the bottle, and the doses-per-day from the doctor. This guide walks through that calculation for every Augmentin strength stocked in Pakistan, plus the parts that matter just as much: how to mix it, how to store it, and when to call back.
What Augmentin is and what it treats
Augmentin (brand name from GSK) is a combination of two drugs. Amoxicillin is a penicillin-class antibiotic that kills bacteria by breaking their cell walls. Clavulanic acid is a "shield-breaker" that blocks the enzyme some bacteria use to inactivate amoxicillin. Together, the combination handles a wider range of infections than amoxicillin alone, which is why Pakistani paediatricians reach for it for resistant ear infections, sinusitis, and complicated chest infections.
Common situations where Augmentin Syrup is prescribed in Pakistan:
- Acute otitis media (middle-ear infection) that has not cleared on plain amoxicillin
- Tonsillitis with throat swab confirming bacterial cause
- Acute sinusitis lasting more than 10 days
- Community-acquired pneumonia (mild cases, treated at home)
- Skin and soft-tissue infections, including impetigo
- Animal-bite wound prophylaxis
- Recurrent urinary tract infections sensitive to amoxicillin-clavulanate
Augmentin will not help viral illness, most colds, throat irritation from smog, and viral diarrhoea. Using it for those just exposes the child to side effects and accelerates antibiotic resistance.
The three Augmentin Syrup strengths in Pakistan
Pakistani pharmacies stock at least three Augmentin Syrup strengths, plus competing brands with the same generic (Co-Amoxiclav). The number you care about is the amoxicillin component in milligrams per 5 mL.
| Strength on bottle | Amoxicillin per 5 mL | Clavulanic acid per 5 mL | Typical age range |
|---|---|---|---|
| Augmentin 156 mg / 5 mL | 125 mg | 31.25 mg | Infants and toddlers (6 months to 3 years) |
| Augmentin 312 mg / 5 mL | 250 mg | 62.5 mg | Primary-school children (3 to 10 years) |
| Augmentin 457 mg / 5 mL | 400 mg | 57 mg | Older children, twice-daily dosing |
| Augmentin 642 mg / 5 mL (ES) | 600 mg | 42.9 mg | Resistant infections, specialist use only |
The total on the bottle (156, 312, 457) is amoxicillin plus clavulanic acid combined. The number that matters for the dose calculation is the amoxicillin component on its own, 125, 250, 400, or 600 mg per 5 mL. Read this carefully when you pick up the bottle. Two bottles labelled "Augmentin Syrup" can hold drug at three times the concentration.
How to calculate the right dose for your child
Augmentin is dosed at 25 to 45 mg of amoxicillin per kilogram of child weight per day. The dose-per-day is then split into 2 doses (twice-daily, BD) or 3 doses (TDS) depending on the strength and infection. The paediatrician decides BD vs TDS; you handle the mL conversion.
Here is the simplified table for the two most-prescribed strengths. Round to the nearest 0.5 mL.
Augmentin 156 mg / 5 mL (toddlers, twice daily)
| Child weight (kg) | Dose per administration | Bottle dose marker |
|---|---|---|
| 5 kg | 2.5 mL | half teaspoon |
| 7 kg | 3.5 mL | between half and one teaspoon |
| 10 kg | 5 mL | one teaspoon |
| 12 kg | 6 mL | one teaspoon + 1 mL |
| 15 kg | 7.5 mL | one and a half teaspoons |
Augmentin 312 mg / 5 mL (primary-school children, twice daily)
| Child weight (kg) | Dose per administration | Bottle dose marker |
|---|---|---|
| 12 kg | 3 mL | half teaspoon + 0.5 mL |
| 15 kg | 4 mL | just under one teaspoon |
| 18 kg | 4.5 mL | just under one teaspoon |
| 22 kg | 5 mL | one teaspoon |
| 28 kg | 7 mL | one and a half teaspoons |
These tables assume mid-range dosing (around 40 mg/kg/day amoxicillin). If your paediatrician prescribed "high-dose Augmentin" (usually 80 to 90 mg/kg/day for resistant ear infection), double the mL in the table above and confirm with the doctor before giving.
Always cross-check with the prescription. If the doctor wrote "Augmentin 5 mL BD" for a 22 kg seven-year-old, that is correct on the 312 mg strength but a quarter of the right dose on the 156 mg strength. Read the bottle.
Reconstitution: how to mix the bottle correctly
Augmentin Syrup arrives as dry powder. The pharmacist usually mixes it before handing it over, but mothers sometimes get the unmixed bottle. The mixing step matters because under-mixing or over-filling gives the wrong concentration.
- Tap the bottle on the counter so the powder is loose at the bottom.
- Add cooled, boiled water in two portions to the marked line on the bottle. Add the first half, shake hard for 30 seconds, then top up to the line. Adding all the water at once leaves powder stuck to the upper walls.
- Shake vigorously until no visible lumps remain.
- Write the date of mixing on the bottle with a pen. The reconstituted syrup is only good for 7 days at room temperature in Pakistani summer heat or 14 days in the fridge.
- Shake the bottle for 5 seconds before every single dose. The active drug settles out within hours.
Storage rules that change the dose your child actually gets
Reconstituted Augmentin Syrup is sensitive to heat. In a Karachi or Multan summer, a bottle left on the kitchen counter loses 20 to 30 percent of its potency in 48 hours. The fridge solves this, keep the bottle in the door compartment of the refrigerator (not the freezer) and bring it out 10 minutes before dosing so it is not ice cold on the child's mouth.
Throw out any leftover syrup at the end of the prescribed course. Storing a half-bottle for "next time" is the most common parent shortcut and the worst, older bottles have lower drug concentration and contribute to under-treatment and resistance.
Side effects to watch for
Mild side effects are common with Augmentin and usually do not require stopping the drug:
- Loose stools or mild diarrhoea (15 to 30 percent of children), keep up with fluids; use ORS if more than 3 loose stools per day.
- Nappy rash from yeast overgrowth in babies still in nappies.
- Mild stomach pain, especially when given on an empty stomach.
Giving the dose with a small amount of food (a bite of banana, a sip of milk) reduces both stomach pain and diarrhoea without affecting absorption.
Stop the drug and contact the paediatrician immediately if any of the following appear: a rash that is widespread or appears within minutes of a dose, swelling of the face or lips, difficulty breathing, severe persistent diarrhoea with blood or mucus, yellowing of the eyes or skin. These are rare but serious. Penicillin allergy is the most important one, if a sibling or parent has a confirmed penicillin allergy, mention this to the doctor before Augmentin is even prescribed.
Finish the full course, even if your child is better
Augmentin courses are typically 5 to 7 days. Children with ear or chest infections feel better by day 2 or 3. Stopping early is the leading reason for relapse and the second-leading reason for antibiotic resistance, after over-prescription. Finish every dose on the schedule the paediatrician gave you, even if the child is back at school and asking for biryani.

My child weighs 9 kg and the doctor wrote 5 mL twice daily of Augmentin Syrup. Is that the right dose?
If the bottle is the 156 mg/5 mL strength, 5 mL twice daily for a 9 kg child works out to about 28 mg/kg/day, a reasonable mild-infection dose. If the bottle is the 312 mg/5 mL strength, 5 mL twice daily would be roughly 55 mg/kg/day, which is at the upper end and only appropriate for severe ear infection or pneumonia. Confirm the strength of the bottle with the pharmacy before starting, and call the paediatrician if the strength does not match what was prescribed.
Can I give Augmentin Syrup with milk or in a feeding bottle?
A small amount of milk or food right before the dose is fine and helps reduce stomach upset. Mixing the syrup into a full bottle of milk is a bad idea, your child may not finish the whole bottle and you cannot tell how much drug they actually took. Use the measuring syringe or spoon that came with the bottle, give the dose directly into the mouth, then offer milk or food.
What if my child vomits within 30 minutes of the dose?
If the vomit clearly contains the medicine (you can see the syrup), repeat the full dose. If it has been more than 30 minutes since the dose, the drug has likely absorbed; do not repeat. If your child is vomiting repeatedly and cannot keep the medicine down, call the paediatrician, switching to an injectable formulation in clinic for the first day is sometimes needed.
Can I keep the leftover Augmentin Syrup for the next time my child gets sick?
No. Once mixed, Augmentin Syrup is only stable for 7 days at room temperature and 14 days refrigerated. Beyond that the drug breaks down and the bottle becomes weak. Also, the next infection may not be the same kind; reusing an old antibiotic without a doctor's review is one of the biggest drivers of resistance in Pakistani communities. Throw out leftover syrup.
Is Augmentin Syrup safe in newborn babies?
The 156 mg/5 mL strength is licensed for infants from 6 weeks onwards, but dosing in babies under 3 months should always be supervised by a paediatrician, with weight checked on the day of prescription rather than from a previous visit. Newborns under 6 weeks need specialist input, Augmentin is not the first-line choice in this age group and dosing intervals are different.
