What ALPHAMOX is used for
ALPHAMOX contains the active ingredient amoxicillin, which is an antibiotic that belongs to a group of medicines called penicillins.
ALPHAMOX is used to treat a range of infections caused by bacteria. These may be infections of the chest (pneumonia), tonsils (tonsillitis), sinuses (sinusitis), urinary and genital tract, skin and fleshy tissues.
ALPHAMOX works by killing the bacteria that causes these infections. ALPHAMOX can also be used to prevent endocarditis (heart infection) in some people.
ALPHAMOX will not work against infections caused by viruses, such as colds or flu.
Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.
This medicine is available only with a doctor's prescription.

Taking other medicines
