Amoxicillin 250 mg + clavulanic acid 125 mg
Amoxicillin/clavulanic acid is a combination of penicillin-type antibiotic used to treat a wide variety of bacterial infections.
Amoxicillin
A semisynthetic antibiotic, with a broad spectrum of bactericidal activity against many Gram-positive and Gram-negative microorganisms. They do not directly kill bacteria, but they stop bacteria from multiplying by preventing bacteria from forming the walls that surround them. The walls are necessary to protect bacteria from their environment and to keep the contents of the bacterial cell together. Amoxicillin is effective against many different bacteria including H. influenzae, N. gonorrhoea, E. coli, Pneumonococci, Streptococci, and certain strains of Staphylococci. The FDA approved Amoxicillin in December 1974.
Clavulanic acid
Clavulanic acid is a beta-lactam structurally related to the penicillins and possesses the ability to inactivate some beta-lactamases by blocking the active sites of these enzymes. Binding and irreversibly inhibiting the beta-lactamase results in a restoration of the antimicrobial activity of beta-lactam antibiotics against lactamase-secreting-resistant bacteria. It enhances the effectiveness of amoxicillin against bacteria that are ordinarily resistant to amoxicillin alone.

It may cause live bacterial vaccines (such as typhoid vaccine) not to work as well. Therefore, do not have any immunizations/vaccinations while using this medication
During pregnancy, this medication should be used only when clearly needed.
