Augmentin
In brief
- Augmentin can be purchased from pharmacies and authorised online pharmacies in the UK, EU and other major markets; however, it is a prescription-only medicine in official regulations. If a pharmacy offers it without a prescription, this may be subject to local rules and verification requirements.
- Augmentin is used to treat a range of bacterial infections, including sinusitis, otitis media, bronchitis, skin and soft tissue infections, urinary tract infections, and more severe infections. It contains amoxicillin and clavulanic acid (co-amoxiclav): amoxicillin kills bacteria, while clavulanic acid inhibits beta-lactamase enzymes that would otherwise break down the antibiotic.
- The usual adult dose is 500/125 mg every 8–12 hours or 875/125 mg every 12 hours for many common infections. Severe infections may require 1.2 g intravenously every 8 hours. Doses for children are based on body weight.
- It is available as tablets, film-coated tablets, oral suspension, paediatric dry syrup, and injectable vials for intravenous use.
- Augmentin usually starts working within a few hours, although you may begin to feel better after 1–3 days as the infection responds to treatment.
- The duration of action is about 8–12 hours per dose, depending on the strength and formulation, which is why it is commonly taken two to three times daily.
- Alcohol is best avoided or kept to a minimum while taking Augmentin, as it may increase stomach upset, dizziness, and dehydration, and can make it harder to recover from infection.
- The most common side effects are diarrhoea, nausea, vomiting, mild skin rash, and stomach discomfort. Oral or vaginal candidiasis and temporary increases in liver enzymes can also occur.

Latest UK And EU Research Findings On Augmentin
What does the newer evidence say about co-amoxiclav in everyday British practice?
Across UK and EU stewardship updates from 2022 to 2025, Augmentin, also known as co-amoxiclav, remains a prescription-only antibiotic used when amoxicillin and clavulanic acid is more likely to succeed than plain amoxicillin alone.
That usually means infection is suspected to involve beta-lactamase-producing bacteria, or resistance to amoxicillin is a concern in community respiratory, skin, or urinary infections.

Key Research And Stewardship Takeaways
| Topic | What UK And EU Evidence Points To | Clinical Meaning |
|---|---|---|
| Resistance | Co-amoxiclav is preferred when beta-lactamase producers are suspected. | More useful than amoxicillin alone in selected community infections. |
| Respiratory Use | Used where plain amoxicillin is less likely to work in sinus, ear, and bronchial infections. | Often chosen when local resistance patterns make broader cover sensible. |
| Skin And UTI Use | Remains a practical option for some skin/soft tissue infections and selected UTIs. | Guided by symptoms, likely organisms, and local formularies. |
| Safety | Common adverse effects include diarrhoea, nausea, vomiting, and mild rashes. | GI tolerability is a real-world reason people stop early. |
| Liver Signals | Transient increases in liver enzymes can occur. | Monitoring matters in people with liver disease or prior hepatic problems. |
Data highlights: the main trade-off with Augmentin is broader antibacterial cover versus more gastrointestinal upset.
For stewardship, that makes co-amoxiclav useful, but not a default choice for every infection.
EMA and MHRA-aligned prescribing still favour the narrowest effective antibiotic, so Augmentin is reserved for situations where that extra clavulanic acid really adds value.
Clinical Effectiveness Of Augmentin In NHS Practice
When do patients in the NHS actually get better with Augmentin?
In practice, effectiveness is judged by symptom recovery, not just the laboratory result.
For many people, that means a blocked sinus starts easing, ear pain settles, a chesty cough becomes less troublesome, or a skin infection stops spreading.
- Sinusitis, otitis media, and bronchitis: often treated with 500/125 mg every 8 to 12 hours, or 875/125 mg every 12 hours for 5 to 10 days.
- Skin and soft tissue infection: usually 500/125 mg every 8 to 12 hours for 7 to 14 days.
- Selected UTIs: commonly 500/125 mg every 12 hours for 7 to 10 days.
- Why it is chosen: when beta-lactamase-producing bacteria are suspected, or when first-line amoxicillin is less likely to work.
| Indication | Common Adult Regimen | Typical Course |
|---|---|---|
| Respiratory infection | 500/125 mg every 8 to 12 hours or 875/125 mg every 12 hours | 5 to 10 days |
| Skin infection | 500/125 mg every 8 to 12 hours | 7 to 14 days |
| Urinary infection | 500/125 mg every 12 hours | 7 to 10 days |
Patients often judge success by whether they can get back to work, sleep, or look after children without feeling wiped out.
The practical burden can be the other side of the coin, especially if diarrhoea makes it hard to keep doses down.
Indications And Approved Uses In The UK
What can Augmentin be used for in NHS care, and what sits outside the routine licence?
- Sinusitis
- Used when a prescriber wants broader cover than amoxicillin alone.
- Otitis media
- Helpful where resistant organisms are suspected.
- Bronchitis
- Selected cases only, based on clinical judgement and local guidance.
- Skin And Soft Tissue Infection
- Chosen when mixed flora or beta-lactamase production is a concern.
- Selected UTI
- Used when the expected organism profile supports it.
In the UK, local formularies can differ between England, Scotland, Wales, and Northern Ireland, so the same infection may be treated differently from one area to another.
Formulations include tablets, oral suspension, and IV vials, with strengths such as 250/125 mg, 500/125 mg, and 875/125 mg.
| Formulation | Route | Typical Use |
|---|---|---|
| Tablet | Oral | Adults and older children |
| Oral suspension | Oral | Children and people who cannot swallow tablets |
| IV vial | Intravenous | Severe infection under medical supervision |
Composition, Brand Names, And UK Supply Landscape
Why do patients sometimes get Augmentin, but other times a different box with the same medicine inside?
The active ingredients are amoxicillin and clavulanic acid, and the UK may label it as co-amoxiclav or Augmentin.
That is the same medicine identity, ATC code J01CR02, even when the packaging changes.
| Brand Or Generic | Active Ingredients | Dosage Forms |
|---|---|---|
| Augmentin | Amoxicillin and clavulanic acid | Tablets, oral suspension, IV vial |
| Co-amoxiclav | Amoxicillin and clavulanic acid | Film-coated tablets, suspension, IV forms |
| Generic co-amoxiclav | Amoxicillin and clavulanic acid | Equivalent dosage forms depending on supplier |
Patients may see the label change because community pharmacies sometimes dispense an equivalent generic product.
That is normal in UK practice, provided the strength and directions match the prescription.
Some people ask if this means the medicine is weaker.
It does not.
Contraindications And High-Risk Groups
Who should be especially careful with Augmentin?
- Do not use it if there is known penicillin or beta-lactam allergy.
- Do not use it if there has been prior cholestatic jaundice or hepatic dysfunction linked to Augmentin.
- Use close monitoring in liver disease, viral hepatitis, or severe renal impairment.
- Watch carefully in people with multiple drug allergies or allergic diathesis.
- Check medication history if allopurinol is being taken, because rash risk may increase.
| Group | Practical Caution |
|---|---|
| Pregnancy | Discuss with the prescriber before starting. |
| Breastfeeding | Ask a pharmacist or GP if the baby develops diarrhoea or thrush. |
| Older adults | Usually same dose if renal function is normal. |
| Chronic illness | Monitoring is sensible if liver or kidney function is already reduced. |
Driving is fine unless side effects affect alertness.
Alcohol is not a direct chemical contraindication, but excess can worsen nausea, diarrhoea, or dehydration.
Dosage Guidelines For Adults, Children, And Special Populations
What dose is right, and for how long?
That depends on the infection, age, kidney function, and the exact formulation prescribed.
| Indication | Adult Dose | Duration |
|---|---|---|
| Sinusitis, otitis media, bronchitis | 500/125 mg every 8 to 12 hours, or 875/125 mg every 12 hours | 5 to 10 days |
| Skin and soft tissue infection | 500/125 mg every 8 to 12 hours | 7 to 14 days |
| Urinary tract infection | 500/125 mg every 12 hours | 7 to 10 days |
| Severe infection | 1.2 g every 8 hours by IV route | As directed |
- Children: dose by weight, with examples of 20 to 40 mg/kg/day of the amoxicillin part in divided doses.
- Elderly: use adult doses if renal function is normal.
- Renal impairment: dose interval extension or dose reduction may be needed.
- Liver impairment: use with caution and monitor hepatic function.
- Treatment length: continue at least 48 hours after symptoms resolve.

UK dosing should always follow the prescription label or pharmacist advice.
Interactions, Food, Alcohol, And Mhra Reporting
Can you take Augmentin with food, alcohol, or other medicines?
| Interaction | What To Know | What To Do |
|---|---|---|
| Allopurinol | May increase rash risk. | Tell the prescriber and pharmacist. |
| Anticoagulants | May need monitoring in general practice. | Ask if INR or bleeding checks are needed. |
| Food | Can improve stomach tolerance. | Take with a meal if advised or if nausea is a problem. |
| Alcohol | Not a direct interaction, but can worsen GI symptoms. | Avoid excess if you are already unwell. |
Suspicion of side effects can be reported through the MHRA Yellow Card scheme.
That report helps track antibiotic resistance, rash, diarrhoea, and other safety signals across the UK.
For interaction checks, a pharmacist at Boots, LloydsPharmacy, Superdrug, or an NHS pharmacy can usually help quickly.
Cultural Perceptions And Patient Habits In The UK
What do people in Britain usually want to know about Augmentin first?
- Will it work quickly?
- Will it upset the stomach?
- Can I keep working while taking it?
- What happens if I miss a dose?
- Is diarrhoea normal?
- Can I breastfeed while taking it?
Those are the same worries seen in community discussions, whether someone has checked patient.info, NHS 111, or a forum such as Mumsnet.
Pharmacist counselling matters because a clear explanation often improves adherence and reduces unnecessary worry.
Myth: if an antibiotic causes diarrhoea, it is not working.
Fact: diarrhoea is a common side effect of co-amoxiclav and does not automatically mean treatment has failed.
Availability And Pricing Patterns Across The UK
How do people usually obtain Augmentin in the UK?
| Access Route | Cost Context | Convenience |
|---|---|---|
| NHS prescription | England may involve the standard prescription charge; Scotland, Wales, and Northern Ireland have fee-exempt systems. | Most familiar route for patients already in NHS care. |
| Private prescription | Usually costs more than NHS supply. | Useful when a private clinician has prescribed it. |
| Online pharmacy | Price depends on prescription and service fees. | Convenient for repeat access and discreet ordering. |
Large chains such as Boots, LloydsPharmacy, and Superdrug may stock different formulations depending on local demand.
Availability can vary because 250/125 mg, 500/125 mg, 875/125 mg, suspension, and IV forms are not handled in exactly the same way everywhere.
In our online pharmacy, augmentin is available without a prescription, with discreet delivery to United Kingdom in 9-21 days.
Comparable Medicines And Prescribing Alternatives
Is Augmentin always the best option?
No, and NHS prescribers often choose differently depending on allergy history, resistance concerns, and side effect risk.
| Medicine | When It May Be Preferred | Main Trade-Off |
|---|---|---|
| Amoxicillin alone | When narrower cover is enough | Less broad, but often better tolerated |
| Cefuroxime | When a cephalosporin is suitable | Alternative if penicillin choice is not ideal |
| Cefixime | Selected infections with local guidance support | Stewardship considerations still apply |
| Azithromycin | When allergy history or clinical context points away from penicillins | Different spectrum and resistance issues |
| Clindamycin | When anaerobic or soft tissue coverage is needed in selected cases | GI adverse effects can be limiting |
- Pros of Augmentin: broader cover, useful for beta-lactamase producers, practical for some mixed infections.
- Cons of Augmentin: more diarrhoea, nausea, and vomiting than amoxicillin alone.
- Stewardship point: not first-line for every infection, because narrower treatment is often preferred when it will work.
Faq: Common UK Patient Questions About Augmentin
How long does Augmentin take to work?
Many people notice some improvement within a few days, but the full course should still be completed.
Can I take it with food?
Yes, food often helps with tolerance and may reduce nausea.
What if I miss a dose?
Take it as soon as you remember, unless the next dose is nearly due.
Do not double up.
When should I seek urgent help for a rash or breathing problem?
Get urgent medical help if there is swelling, wheeze, difficulty breathing, or a rapidly spreading rash, because that can indicate penicillin allergy.
Guidelines For Proper Use And Pharmacist-Style Counselling
What would a UK pharmacist usually say when handing over co-amoxiclav?
- Take doses at evenly spaced times.
- Finish the course, even if you feel better early.
- Do not double a missed dose.
- Store tablets at room temperature.
- Keep reconstituted suspension in the fridge.
- Discard leftover suspension as directed on the label.
- Contact the GP if symptoms worsen or do not improve.
- Use NHS 111 for advice if you are unsure, and emergency services for severe allergy symptoms or collapse.
| Form | Storage Advice | Practical Note |
|---|---|---|
| Tablets | Room temperature, 15 to 25°C | Keep dry and protected from light |
| Oral suspension | Refrigerate after reconstitution | Discard after 7 to 10 days, per label |
| Injectable form | Store as directed, usually cold chain | Handled under clinical supervision |
Checking the label matters because suspension and IV handling differ from tablets.
That is especially important if a parent is using co-amoxiclav oral suspension for a child and a tablet user in the same household is on a different schedule.
