What is amoxicillin + clavulanate potassium used for?
Amoxicillin and clavulanate potassium is a prescription antibiotic used to treat bacterial infections. It’s commonly prescribed for infections in areas such as the ear, sinuses, throat, lungs, and skin, where bacteria are susceptible to amoxicillin and can be resistant due to beta-lactamase enzymes. The clavulanate helps block that resistance, allowing amoxicillin to work more effectively.
Which infections does it commonly treat?
Clinicians often use amoxicillin/clavulanate for conditions like:
- Ear and sinus infections
- Throat infections such as strep throat (when indicated)
- Some respiratory infections (including certain cases of bronchitis or pneumonia)
- Skin and soft-tissue infections, including infected wounds or bites
How does clavulanate change what amoxicillin can treat?
Amoxicillin is a penicillin-type antibiotic, but some bacteria produce beta-lactamase enzymes that can break down amoxicillin. Clavulanate potassium acts as a beta-lactamase inhibitor, which can restore amoxicillin’s activity against those resistant bacteria.
Is it used for viral infections (like the flu or common cold)?
No. Amoxicillin/clavulanate treats bacterial infections, not viruses. It won’t help for conditions such as the common cold or influenza.
Important safety note: only for prescribed bacterial infections
Using antibiotics when they’re not needed can increase side effects and antibiotic resistance. It should be taken exactly as prescribed, and patients should contact a clinician promptly if they develop serious allergic reactions or severe diarrhea.
