Contraindications (do not use if…)
Do not use in a person with a serious immediate allergy to amoxicillin or other penicillin antibiotics. Previous severe beta-lactam reactions require clinician review.

Common side effects
Possible effects include nausea, vomiting, diarrhoea, abdominal discomfort and rash.
Serious side effects — seek urgent medical care
Emergency concerns include anaphylaxis, swelling or breathing difficulty, severe blistering or peeling rash, and severe or persistent diarrhoea that may occur even after treatment has ended.
Important interactions
Important interactions may include warfarin and other anticoagulants, methotrexate, probenecid and allopurinol. A clinician or pharmacist should review concurrent medicines.
Allergy considerations
Penicillin allergy must be clearly documented. Do not take after a serious prior reaction to amoxicillin or another penicillin unless a specialist has assessed the risk.
