What is amoxicillin/clavulanate used for?
Amoxicillin/clavulanate (also written as amoxicillin–clavulanate and commonly known by brand names such as Augmentin) is an antibiotic combination used to treat certain bacterial infections. It pairs:
- Amoxicillin, a penicillin-type antibiotic that attacks bacterial cell walls
- Clavulanate, a beta-lactamase inhibitor that helps protect amoxicillin from bacterial resistance
This combination is typically used for infections where bacteria may produce enzymes that would otherwise break down amoxicillin.
How does clavulanate change the way amoxicillin works?
Some bacteria produce beta-lactamase enzymes that can inactivate amoxicillin. Clavulanate inhibits those enzymes, so amoxicillin can keep working against a broader range of bacteria than amoxicillin alone.
What forms and dosing are commonly available?
Amoxicillin/clavulanate is commonly prescribed in oral forms (tablets and liquid suspensions). The key dosing variable is usually the amount of amoxicillin, with clavulanate included in a fixed ratio depending on the specific formulation.
If you’re trying to match a prescription, the exact product strength and formulation matter (because “mg per mL” for suspensions and “mg per tablet” for tablets can differ).
Common side effects people ask about
Patients commonly report gastrointestinal effects, including:
- Diarrhea
- Nausea
- Stomach upset
Because it is an antibiotic, it can also contribute to yeast overgrowth in some people.
When to avoid it or use caution
Many clinicians consider avoidance or extra caution if a patient has:
- A history of serious allergy to penicillin-class antibiotics
- A history of antibiotic-associated severe diarrhea or colitis
If you’re pregnant, breastfeeding, or have significant liver problems, prescribers also consider those factors when choosing therapy.
What to do if symptoms don’t improve
Antibiotics for bacterial infections generally start improving symptoms within a few days, but full resolution can take longer depending on the infection type. If symptoms worsen or fail to improve after the prescribed period, the prescriber may:
- Reassess the diagnosis (sometimes the cause is viral or non-bacterial)
- Adjust antibiotics based on local guidance or culture results
Does it matter which infection it’s for?
Yes. Amoxicillin/clavulanate is used when bacterial coverage is needed and when beta-lactamase–producing bacteria are a concern. It is not useful for viral illnesses (like most colds and flu).
