Overall view
Amoxicillin-clavulanate is a combined oral antibiotic that pairs amoxicillin, a penicillin-type agent that disrupts bacterial cell wall synthesis, with clavulanate, an inhibitor of many beta-lactamase enzymes. The clavulanate component extends amoxicillin's activity to organisms that produce beta-lactamases.
In U.S. pharmacies the product is supplied in several oral forms: conventional film-coated tablets, chewable tablets, and reconstituted liquid suspensions. Common tablet potencies seen in adult prescriptions include:
- amoxicillin 500 mg with 125 mg clavulanic acid
- 875 milligrams of amoxicillin plus 125 milligrams of clavulanate
- 250 mg amoxicillin plus 125 mg clavulanate therapy
This antibiotic is used when likely pathogens or susceptibility testing suggest benefit from a beta-lactamase-stable regimen. For instant navigation, jump to which conditions fall under its treatment or assess dose calculation guidance.
Signs and symptoms for Medical Use
Clinicians often select amoxicillin-clavulanate when beta-lactamase production is a concern. Typical cues include:
- Acute bacterial sinusitis and community-acquired pneumonia
- Acute exacerbations of chronic bronchitis and other lower respiratory infections
- Otitis media or middle ear infection in appropriate cases
- Skin and soft-tissue infections, including some animal or human bite wounds
- Upper tract infections of the urinary system due to susceptible organisms
- Dental infections and selected intra-abdominal infections as part of clinician-directed therapy
Note: This medicine treats bacterial infections only. It does not work for viruses and is not indicated for noninfectious uses.

Therapeutic Dose and Administration Procedures
Choice of dose depends on the infection, severity, patient age, and kidney function. Prescribers balance sufficient amoxicillin exposure with minimizing clavulanate-related gastrointestinal effects.
- Typical adult regimens:
- Mild to moderate infections: 500 mg/125 mg every 12 hours, or 250 mg/125 mg every 8 hours
- More severe infections, such as many cases of pneumonia: 875 mg/125 mg every 12 hours
- Best practices for administration:
- Take doses at roughly even intervals across the day.
- Take with food to improve stomach tolerance, especially to reduce nausea.
- Swallow standard tablets whole; chewables should be chewed before swallowing.
Always follow the exact instructions from your prescriber. Complete the full course even if symptoms improve early. If you have reduced renal function, the dose or interval may need adjustment — discuss with your healthcare provider. For relevant warning notices that could alter dosing, see safety notes.
Notes on Safety
- Allergy: Inform your clinician if you have a known allergy to penicillins or cephalosporins prior to receiving this drug.
- Liver concerns: Use cautiously in patients with liver disease. Prior liver injury attributed to this combination is a reason to avoid reuse.
- Kidney disease: Renal impairment can necessitate dose changes.
- C. difficile risk: Broad-spectrum antibiotics can disturb gut flora and permit Clostridioides difficile overgrowth, which may cause severe diarrhea.
- Gestation and baby feeding support: Use only when clearly indicated; discuss benefits and risks in conjunction with your prescriber. Nursing infants may develop loose stools or rash if exposed through breast milk.
For absolute exclusions, see situations where this drug is unsafe. For adverse events that require urgent carereviewing the material side effect notifications of danger.
For whom this medicine is not recommended
Do not take amoxicillin-clavulanate if any of the following apply:
- Known hypersensitivity to amoxicillin, clavulanate, or any penicillin-class antibiotic
- History of cholestatic jaundice or hepatic dysfunction after prior use of amoxicillin-clavulanate
- Cases of infectious mononucleosis: ampicillin-type antibiotics frequently produce a rash in these patients
If you are uncertain whether this list applies to you, consult your prescribing clinician before taking the medicine.
Probable adverse effects
Many people tolerate the drug well; common mild effects include:
- Gastrointestinal discomfort: nausea, vomiting, abdominal pain, diarrhea, gas
- Liver-related laboratory elevations; infrequent reports of cholestatic jaundice or hepatitis
- Hypersensitivity reactions: skin rash, hives, swelling; severe allergic reactions such as anaphylaxis are rare but require immediate emergency care
- Vaginal upset: yeast infections or abnormal discharge due to altered normal flora
- Non-specific: suffering from a headache, dizziness, fatigue
Call urgent care for severe rash, difficulty breathing, persistent vomiting, signs of liver injury such as yellowing of skin or eyes, dark urine, or severe watery diarrhea.
Alerts About Medication Interactive encounters
- Probenecid chemical: can reduce renal excretion of amoxicillin and raise systemic levels.
- Warfarin and other vitamin K antagonists: antibiotics can alter gut flora and vitamin K production; monitor INR if coadministered.
- Methotrexate therapy regimen: penicillins may reduce methotrexate clearance and increase the risk of toxicity.
- Allopurinol: concurrent use has been associated with a higher risk of skin rash.
- Oral contraceptives: breakthrough bleeding has been reported with some antibiotics; use an additional barrier method if concerned.
- Live oral bacterial vaccines: systemic antibiotics may decrease the effectiveness of oral live bacterial vaccines.
Always tell your prescriber and pharmacist about all prescription medicines, over-the-counter drugs, vitamins, and supplements you take. Similar topics safety information.
Immediate Steps After Missing a Dose
If a dose goes untaken, take it at the first moment you remember it, unless the next dose is due soon. Do not take two doses at the same time to settle a i missed the dose.
Overdose scenario First Aid Guidance
Symptoms of overdosing may include severe nausea, vomiting, abdominal pain, diarrhea, drowsiness, or restlessness. In the United States, contact Poison Control at 1-800-222-1222 or seek emergency medical attention immediately if an overdosing is suspected.
Storing guidance
- Store tablets at controlled room temperature, generally between 59 and 86 F (15 and 30 C).
- Protect from moisture and prolonged exposure to direct light; keep in the original, tightly closed container.
- Store reconstituted suspensions according to label instructions; many require refrigeration and have limited stability once mixed.
- Ensure meds are kept out of reach of children and pets.

Side by Side Alternative solutions and Comparisons
Choice of an a backup route depends on the infecting organism, local resistance patterns, patient allergy history, conjoined with the site of infection. Some commonly used different choices include:
- Amoxicillin alone: appropriate when beta-lactamase production is unlikely and a narrower-spectrum drug is preferred
- Cephalexin: a first-generation cephalosporin often used for uncomplicated skin infections
- Doxycycline: useful for certain respiratory infections and some community-associated MRSA strains
- Azithromycin: a macrolide used for selected respiratory infections; regional resistance may limit effectiveness
- Clindamycin: effective against many anaerobes and gram-positive organisms but carries elevated risk of C. difficile infection
- Cefuroxime or cefdinir: oral cephalosporins for some respiratory and urinary infections
- Sulfamethoxazole/trimethoprim: used for urinary and certain skin infections based on susceptibility
