Augmentin BID 1000mg 10 Tablets – Broad-Spectrum Antibiotic (2026)

Key facts about Augmentin

What is Augmentin?

Augmentin is a widely used prescription antibiotic that combines two active ingredients: amoxicillin, a penicillin-type antibiotic, and clavulanic acid, which protects the amoxicillin from being broken down by resistant bacteria. This combination broadens the range of bacteria it can treat, which is why it is described as broad-spectrum. The BID 1000 mg form is designed for twice-daily dosing.

How does it work?

Amoxicillin kills bacteria by interfering with the building of their cell walls, causing them to break down. Some bacteria produce an enzyme (beta-lactamase) that inactivates amoxicillin; clavulanic acid blocks this enzyme, allowing the amoxicillin to work against otherwise resistant organisms. Together they clear a wider range of bacterial infections.

What it is used for

Doctors prescribe Augmentin for various bacterial infections, including certain chest and respiratory infections, sinusitis, ear infections, urinary tract infections, dental infections and skin and soft-tissue infections. The specific use, dose and duration are decided by the prescribing doctor based on the infection.

Why it is prescription only

Antibiotics like Augmentin require a doctor’s diagnosis because they must match the right infection, dose and duration. Using them incorrectly — for viral illnesses, at the wrong dose, or without finishing the course — is ineffective and contributes to antibiotic resistance, a serious global health problem. This is why self-medication with antibiotics is strongly discouraged.

Complete the full course

This is essential. Take every dose at the times your doctor advises, and finish the entire course even once you feel better. Stopping early can leave surviving bacteria that may cause the infection to return and become harder to treat, encouraging resistance. Never save leftover antibiotics or share them with others.

How to take it

Take Augmentin exactly as prescribed, usually twice daily at evenly spaced intervals, ideally at the start of a meal to reduce stomach upset and aid absorption. Swallow the tablets whole with water. If you miss a dose, take it as soon as you remember unless it is nearly time for the next — never double up.

Allergy warning

Do not take Augmentin if you are allergic to penicillins or have had a serious reaction to them. Signs of an allergic reaction include rash, itching, swelling of the face or throat, and difficulty breathing — these require emergency medical help. Always tell your doctor about any drug allergies before it is prescribed.

Possible side effects

Common side effects include diarrhoea, nausea and mild stomach upset. Taking it with food helps. Antibiotics can sometimes cause thrush or, less commonly, a more serious bowel infection causing severe or bloody diarrhoea, which needs medical attention. Rarely, liver effects can occur. Report any severe or unusual symptoms to your doctor.

Precautions and interactions

Tell your doctor if you have kidney or liver problems, glandular fever, or take other medicines, as Augmentin can interact with some drugs including certain other antibiotics, blood thinners and, in some cases, affect the reliability of oral contraceptives. Discuss reliable contraception if relevant.

When to see a doctor

Seek urgent help for signs of an allergic reaction, severe or bloody diarrhoea, yellowing of the skin or eyes, or if your infection worsens or does not improve. Always follow up as your doctor advises, and never restart or reuse antibiotics for a new illness without a fresh assessment.

Frequently asked questions

What is Augmentin used for?

It treats various bacterial infections, such as chest, sinus, ear, urinary, dental and skin infections. It does not work against viral illnesses like colds or flu.

Can I take Augmentin without a prescription?

No. It is a prescription-only antibiotic requiring a doctor’s diagnosis, correct dose and duration. Self-medication is ineffective and fuels antibiotic resistance.

Why must I finish the whole course?

Stopping early can leave surviving bacteria, causing the infection to return and become harder to treat, and encouraging antibiotic resistance.

How should I take Augmentin?

Exactly as prescribed, usually twice daily at evenly spaced times, ideally at the start of a meal to reduce stomach upset. Swallow whole with water.

Who should not take Augmentin?

Anyone allergic to penicillins should not take it. Tell your doctor about drug allergies, kidney or liver problems, and other medicines before use.

Your role in fighting antibiotic resistance

Every time an antibiotic like Augmentin is used correctly, it helps preserve its effectiveness for the future; every time one is misused, resistant bacteria are given an advantage. Using antibiotics only when a doctor prescribes them, taking the full course, never sharing or saving them, and not pressing for antibiotics when an illness is viral are simple actions that protect not just your own health but that of the wider community. Responsible use today keeps these life-saving medicines working tomorrow.

Bottom line

Augmentin BID 1000mg is a prescription broad-spectrum antibiotic combining amoxicillin and clavulanic acid to treat bacterial infections. It must be prescribed by a doctor, taken exactly as directed, and completed in full even if you feel better, to clear the infection and help prevent antibiotic resistance. It does not treat viral illnesses. Report any allergic reaction or severe side effects to your doctor immediately.
