Consulting an accurate Augmentin ( Amoxicillina/Aclavulanato ) dosage chart is the first step toward a successful recovery when your doctor prescribes this antibiotic. As a pharmacist, I often see small timing errors that can lead to ineffective treatment or side effects.”
The Golden Rule: Every 12 Hours, On the Dot
To maintain a steady level of antibiotic in the bloodstream to fight bacteria, you must take Augmentin exactly every 12 hours.
- Timing is everything: Do not wait “around” 12 hours. Set an alarm.
- Before, not after: Always take your dose at the start of a meal. Taking it just before you eat maximizes absorption and significantly reduces the risk of stomach upset and nausea.

💡 The Pharmacist’s Quick Math: > “Can’t find your child’s exact weight on the chart? Here is my simple rule for a standard dose: Multiply your child’s weight in kilograms by 0.3.
Example: If your child weighs 10 kg, 10 x 0.3 = 3 mL.
This gives you the exact amount in mL to administer every 12 hours. Always use an oral syringe for precision, never a kitchen spoon!”
Important: Storage & Preparation Instructions
❄️ Storage Requirement: > Once reconstituted (mixed), Augmentin oral suspension must be stored in the refrigerator between 2°C and 8°C (36°F to 46°F). Discard any unused portion after 10 days. Do not freeze.
How to Properly Mix Your Suspension
Many parents make the mistake of adding all the water at once, which leads to clumps and incorrect dosing. Follow this “Two-Step” method:
- Tap the Bottle: Before opening, tap the bottle on a hard surface to loosen the powder.
- First Fill: Add about half of the required amount of water (purified or distilled is best).
- Shake Well: Close the cap tightly and shake vigorously to wet all the powder.
- Final Adjustment: Wait a few moments for the foam to settle. You will notice the liquid level is now below the fill line. Add more water exactly up to the fill line marked on the bottle.
- Second Shake: Shake one last time to ensure a uniform mixture.
Pharmacist’s Tip: Always shake the bottle well before every single dose to ensure your child gets the correct amount of medication.
Adult Augmentin Dosage Chart and Guidelines
For adults and children weighing over 40kg (88 lbs), the dosage typically switches to tablets:
| Condition Severity | Dosage (875mg/125mg) | Frequency |
| Standard Infections | 1 Tablet / Sachet | Every 12 hours (Twice a day) |
| Severe / Persistent | 1 Tablet / Sachet | Every 8 hours (Three times a day) |
This Augmentin dosage chart for adults typically switches to tablets once a patient weighs over 40kg (88 lbs)
Protect Your Gut: The Pharmacist’s Secret
Antibiotics don’t just kill “bad” bacteria; they also affect your healthy gut flora. Pharmacist Recommendation: I always advise pairing Augmentin with a high-quality probiotic (fermenti lattici) and a Vitamin B complex to restore your internal balance and prevent antibiotic-associated diarrhea.

Pharmacist’s Tip: “During antibiotic therapy, your gut flora is disrupted, often leading to B-vitamin depletion. I recommend Solgar B-Complex 100 to support energy levels and protect the oral mucosa from painful canker sores (aphthae) while your body fights the infection.”
