What Is Amoxicillin/Clavulanate 250mg/125mg?
Amoxicillin/clavulanate potassium is a prescription antibiotic that combines two medicines in one tablet. Amoxicillin is a penicillin-class antibiotic that stops bacteria from building their cell walls, while clavulanate potassium blocks bacterial enzymes (beta-lactamases) that can make amoxicillin ineffective. Together, they treat a broader range of bacterial infections than amoxicillin alone. It is sold under the brand name Augmentin and works only against bacterial infections, not viral illnesses like colds or flu.
