How it is used

Bacterial infections. The choice of medicine, length of treatment and method of use are decided based on the clinical reason, other conditions and the specific approved product.

LEARN THE ESSENTIALS

How it works

Amoxicillin is a beta-lactam antibiotic. It interferes with the synthesis of bacterial cell walls in susceptible organisms, leading to bacterial death. The drug does not affect viruses, and resistance can prevent it from working against certain bacteria.

The exact therapeutic benefits and safety risks depend on the formulation, indication and person. Check the linked approved reference for clinical details.
