Systemic antibiotic \u2013 penicillin/\u03b2-lactamase inhibitor
Description
Co-Amoxiclav 500/125 mg film-coated tablets are a prescription-only, broad-spectrum antibiotic combination containing amoxicillin 500 mg and clavulanic acid 125 mg per tablet. Amoxicillin is a β-lactam penicillin that kills susceptible bacteria by inhibiting cell wall synthesis, while clavulanic acid is a β-lactamase inhibitor that protects amoxicillin from enzymatic breakdown. Co-amoxiclav is used in adults and children to treat a range of infections, including respiratory tract infections, ear, nose and throat infections, urinary tract infections, skin and soft-tissue infections (including dental infections), and bone and joint infections. The usual adult dose for this strength is one 500/125 mg tablet three times daily, taken for as long as prescribed by a healthcare professional.
Bnefits
- Broad-spectrum antibiotic activity against a wide range of β-lactamase–producing and non–β-lactamase–producing bacteria
- Combination of amoxicillin with clavulanic acid overcomes many forms of β-lactamase–mediated resistance
- Effective in common community-acquired infections such as sinusitis, otitis media, bronchitis, pneumonia and urinary tract infections
- Indicated for skin and soft-tissue infections, including dental infections and animal bites
- Oral film-coated tablet formulation for convenient outpatient therapy
- Widely used, well-characterised safety and efficacy profile supported by SmPC and regulatory data
- Available as a standard 500 mg/125 mg strength allowing thrice-daily dosing in adults
Indications
- Acute bacterial sinusitis (adequately diagnosed)
- Acute otitis media
- Acute exacerbations of chronic bronchitis (adequately diagnosed)
- Community-acquired pneumonia
- Cystitis and other urinary tract infections
- Pyelonephritis
- Skin and soft-tissue infections, particularly cellulitis, animal bites and severe dental abscess with spreading cellulitis
- Bone and joint infections, particularly osteomyelitis
- Use should follow official/local guidance on appropriate use of antibacterial agents
Composition
- Active substances (per film-coated tablet):
- • Amoxicillin trihydrate equivalent to 500 mg amoxicillin
- • Potassium clavulanate equivalent to 125 mg clavulanic acid
- Core excipients (typical SmPC formulation):
- • Microcrystalline cellulose (E460)
- • Sodium starch glycolate (Type A)
- • Colloidal anhydrous silica
- • Magnesium stearate (E470b)
- Film-coating excipients (typical SmPC formulation):
- • Hypromellose (E464)
- • Macrogol 400

Formulation
- Film-coated tablet for oral administration
- Each tablet contains 500 mg amoxicillin (as amoxicillin trihydrate) and 125 mg clavulanic acid (as potassium clavulanate)
- White or off-white, oval, film-coated tablet (appearance may vary slightly by manufacturer)
- Prescription-only medicine (POM)
Packaging
- Blister packs containing 21 film-coated tablets (commonly supplied as 3 blisters × 7 tablets or 3 blisters × 5 tablets plus 1 blister × 6, depending on manufacturer; WMS listing specifies total of 21 tablets)
- Outer carton labelled with product name, strength, batch number and expiry date
Usage
- Use only as prescribed by a doctor or other qualified prescriber.
- Adults and children ≥40 kg: the usual dose for this strength is one 500 mg/125 mg tablet three times a day, with spacing of approximately 8 hours between doses, unless otherwise directed in the SmPC and by the prescriber.
- Tablets should preferably be taken at the start of a meal to minimise potential gastrointestinal side effects and improve absorption.
- Tablets should be swallowed whole with a glass of water and should not be divided unless the specific marketed brand provides a functional score line for this purpose (many Co-amoxiclav 500/125 mg tablets are not intended to be split for dosing).
- Duration of treatment should follow the prescriber’s instructions and relevant guidelines; treatment should not usually exceed 14 days without clinical review.
- If a dose is missed, it should be taken as soon as remembered, unless it is almost time for the next dose. Do not take a double dose to make up for a forgotten dose.
- Complete the full prescribed course even if symptoms improve early, to reduce the risk of relapse and antibiotic resistance.
- Children under 40 kg are typically treated with amoxicillin/clavulanic acid oral suspension or paediatric formulations rather than 500/125 mg tablets.
Contraindications
- Hypersensitivity to amoxicillin, clavulanic acid, any penicillin, or to any of the excipients
- History of severe immediate or severe delayed hypersensitivity reaction (e.g. anaphylaxis, severe skin reaction) to any other β-lactam antibiotic such as cephalosporins, carbapenems or monobactams
- History of jaundice or hepatic dysfunction associated with co-amoxiclav or other penicillins
- Use in patients with infections known to be resistant to amoxicillin/clavulanic acid, where alternative agents are indicated
Adverse Effects
- Very common and common: diarrhoea, nausea, vomiting, abdominal discomfort, and mild skin rashes
- Potential for antibiotic-associated colitis, including Clostridioides difficile–associated diarrhoea
- Allergic reactions ranging from rash and urticaria to anaphylaxis (a medical emergency)
- Liver-related adverse effects including cholestatic jaundice and hepatitis, usually reversible but sometimes delayed in onset
- Headache, dizziness and candidiasis (oral or vaginal thrush) have been reported
- Haematological effects such as reversible thrombocytopenia, leukopenia or eosinophilia may occur
- As with all antibiotics, prolonged use may lead to overgrowth of non-susceptible organisms
Storage Conditions
- Store below 25°C (or as per specific brand SmPC) in the original package to protect from moisture.
- Keep blister strips in the outer carton until use.
- Do not use after the expiry date stated on the carton and blister.
