Interactions with amoxycillin and clavulanic acid
What are the interactions with amoxycillin with clavulanic acid?
Tell your doctor about all the medicines you are taking
It is important that you tell your health professional about all the medicines you or anyone in your care is taking — including prescription, over-the-counter and complementary medicines (herbal, ‘natural’, vitamin and mineral supplements). This is because all medicines, including herbal and natural medicines, can cause side effects and may interact with other medicines.
Tell your doctor if you are taking:
- allopurinol or probenecid (medicines used to treat gout): if you are taking allopurinol or probenecid there is an increased chance that you will develop a rash if you are also taking amoxycillin.
To check if your medicine contains these active ingredients, look on the packaging of your medicine for the active ingredient name, or use our Medicines Finder.
Can I drink alcohol if I am taking amoxycillin with clavulanic acid?
Drinking alcohol in moderation is unlikely to interact with amoxycillin with clavulanic acid, or to cause additional side effects.

Will amoxycillin with clavulanic acid affect my contraceptive?
Amoxycillin with clavulanic acid won’t affect your contraceptive.
Rifampicin-like antibiotics (e.g. rifampicin and rifabutin) are the only types of antibiotic that are known to interact with hormone contraceptives, such as the combined contraceptive pill, making it less effective.
