Avlomox Suspension 125mg/5ml – Paediatric Amoxicillin Oral Suspension

1. About Avlomox Suspension (Amoxicillin 125mg/5ml)

Avlomox Suspension is the standard-strength paediatric oral suspension of Amoxicillin (125mg per 5ml), manufactured by ACI Limited, Bangladesh. Amoxicillin suspension is the most widely prescribed antibiotic suspension for children in Bangladesh and globally, serving as first-line treatment for acute otitis media, bacterial pharyngitis, mild pneumonia, and urinary tract infections in paediatric patients. The flavoured liquid formulation enables accurate weight-based dosing and is suitable for infants and young children who cannot swallow capsules. The 125mg/5ml concentration is the standard starting concentration — higher concentrations are available (250mg/5ml DS) for older children or when smaller volumes are preferable.

2. Indications in Children

• Acute otitis media (AOM) — first-line treatment for children with bacterial middle ear infection
• Streptococcal pharyngitis / tonsillitis (strep throat) — 10-day course to prevent rheumatic fever
• Mild-to-moderate community-acquired pneumonia — first-line oral treatment in children not requiring hospitalisation
• Acute bacterial sinusitis — when bacterial cause is confirmed or highly suspected
• Urinary tract infections — when E. coli is amoxicillin-sensitive (culture and sensitivity recommended)
• Skin and soft tissue infections — mild streptococcal impetigo, mild cellulitis
• Paediatric dental infections — adjunct to dental treatment

3. Dosage and Administration

Standard paediatric dose: 25mg/kg/day in 3 divided doses (TDS), every 8 hours. Using 125mg/5ml suspension: ml per dose = (weight in kg × 25) ÷ 3 ÷ 25 × 5. Example: 12kg child: (12 × 25) ÷ 3 ÷ 25 × 5 = 10ml TDS. High-dose amoxicillin (for suspected drug-resistant S. pneumoniae in AOM or pneumonia): 40–90mg/kg/day — higher volumes required; the 250mg/5ml DS suspension is more practical for high-dose therapy in older children. Duration: 5–7 days for most infections; 10 days for strep throat; 10–14 days for pneumonia. Reconstitution: Add cooled boiled water to the powder (see label for volume); shake well. Refrigerate after reconstitution; use within 7 days. Measure each dose with the supplied oral syringe — not a household teaspoon.

4. Amoxicillin vs Ampicillin Suspension in Children

Amoxicillin suspension has replaced ampicillin suspension as the preferred oral aminopenicillin for children. Key advantages: (1) Better oral bioavailability (85–90% vs ~40% for ampicillin) — more of each dose reaches the bloodstream; (2) Food does not significantly reduce absorption — can be given with feeds without loss of efficacy; (3) Better tissue penetration including middle ear fluid — clinically significant for AOM treatment; (4) Fewer gastrointestinal side effects — less diarrhoea due to greater absorption and less residual drug in the colon; (5) Superior outcomes in clinical trials for AOM and respiratory infections. These pharmacokinetic advantages make amoxicillin the preferred choice in all current paediatric guidelines for the indications listed above.

5. When to Escalate from Amoxicillin to Co-amoxiclav in Children

Escalation from amoxicillin suspension to co-amoxiclav suspension (Avloclav suspension) is indicated when: (1) No improvement after 48–72 hours on amoxicillin; (2) Recurrent AOM or AOM in a child who had antibiotics in the past 30 days (higher beta-lactamase-producing H. influenzae likelihood); (3) AOM with perforation/discharge at presentation (more likely H. influenzae/M. catarrhalis); (4) Severe AOM; (5) Skin infections with suspected S. aureus (beta-lactamase-producing); (6) Bite wounds. Do not escalate simply because the child has diarrhoea on amoxicillin — mild diarrhoea is an expected side effect; ensure the correct dose is being given and it is taken with feeds.

Frequently Asked Questions (FAQ)

Q1: How do I calculate the right dose of Avlomox suspension for my child?

The standard dose is 25mg/kg/day split into 3 equal doses (every 8 hours). Step-by-step calculation for 125mg/5ml suspension: (1) Note your child's current weight in kg; (2) Multiply by 25 to get the total daily mg; (3) Divide by 3 to get mg per dose; (4) Divide by 25 (mg per ml) to get ml per dose. Example for a 15kg child: 15 × 25 = 375mg/day ÷ 3 = 125mg per dose ÷ 25mg/ml = 5ml per dose, three times daily. Always double-check with your pharmacist who will often calculate and label the bottle for you. Use the supplied dosing syringe — kitchen teaspoons vary in volume. Round doses to the nearest 0.5ml for practicality.

Q2: My child refuses to take Avlomox suspension because of the taste — what can I do?

Medication refusal in children is common. Strategies that help: (1) Refrigerate the suspension — the cold temperature reduces taste intensity, and most children find it more palatable than room-temperature suspension; (2) Mix with a small amount of juice or food — amoxicillin can be mixed with a teaspoon of fruit juice, milk, or syrup immediately before dosing; use only a small amount (1–2 teaspoons) to ensure the entire dose is consumed; (3) Give after a small feed — helps reduce the aftertaste; (4) Use a reward system for completion; (5) Syringe technique — place the syringe tip along the inside of the cheek (not at the back of the throat) and give slowly in small squirts. If the child vomits within 30 minutes of a dose, a repeat dose may be given once. If vomiting persists, contact your doctor — alternative antibiotic formulations or IV treatment may be needed.

Q3: Can I mix Avlomox suspension with formula or breast milk for my infant?

Mixing amoxicillin suspension with formula or breast milk for administration is generally acceptable as a last resort when direct oral administration is refused, but with important caveats: (1) Mix with the smallest practical volume — just enough to ensure consumption (1–2 teaspoons); do not add to an entire bottle feed as the infant may not finish it and you won't know how much antibiotic was consumed; (2) Mix immediately before feeding — do not pre-mix and store; (3) Amoxicillin is stable in formula/milk for a short period but exposure to stomach acid from digested milk may slightly alter absorption — give on a semi-empty stomach when possible for most reliable absorption. For infants under 3 months, consult your paediatric doctor before adjusting administration technique. Direct oral administration with a small syringe (bypassing mixing) is preferred when feasible.

Q4: How is Avlomox suspension different from Avloclav suspension for children?

The key difference is that Avloclav contains both amoxicillin AND clavulanic acid, while Avlomox suspension contains only amoxicillin. Clavulanic acid is a beta-lactamase inhibitor — it blocks the enzyme that some bacteria produce to destroy amoxicillin, restoring amoxicillin's activity against resistant organisms. Avlomox (plain amoxicillin) is appropriate when: (1) First-episode infections with susceptible organisms; (2) Strep throat (S. pyogenes is always amoxicillin-sensitive — no beta-lactamase); (3) Confirmed amoxicillin-susceptible infections. Avloclav is needed when: (1) Amoxicillin has failed; (2) Beta-lactamase-producing organisms are suspected (H. influenzae, S. aureus, M. catarrhalis, Bacteroides); (3) Bite wounds; (4) Recurrent or severe AOM. Starting with Avlomox for appropriate indications follows antibiotic stewardship principles — reserve the broader-spectrum Avloclav for when it is genuinely needed.
