What this medicine is used for
Amoxycillin and clavulanic acid is used to treat a wide range of infections caused by bacteria. These infections may affect the chest (bronchitis or pneumonia), bladder (cystitis), sinuses (sinusitis), ears (otitis media) or skin.
How it works
Amoxycillin is a type of penicillin antibiotic. Clavulanic acid is used to help the amoxycillin work better against certain types of bacteria.
Amoxycillin and clavulanic acid works by killing the bacteria that cause these infections. It will not work against viral infections such as colds or the flu, which are caused by viruses.

Your doctor may have prescribed this medicine for another reason.
This medicine is available only with a doctor’s prescription.

Follow all directions given to you by your doctor or pharmacist carefully.
They may differ to the information contained in this leaflet.
If you do not understand the instructions on the box, ask your doctor or pharmacist for help.
How much to take
Your doctor will tell you how much of this medicine you should take. This will depend on your condition and whether you are taking any other medicines.
The usual dose is one tablet twice a day (approximately every 12 hours).
How to take it
Swallow the tablet whole with a full glass of water.
The tablets may be broken in half but should not be chewed.
When to take it
Take the tablet immediately before or with the first mouthful of food.
This medicine works best when taken this way and may help to prevent stomach upsets.
Take this medicine at about the same time each day.
Taking it at the same time each day will have the best effect. It will also help you remember when to take it.
Space the doses as evenly as possible throughout the day.
If you are taking the tablets twice a day, take a dose about every 12 hours.
How long to take it for
Continue taking your medicine for as long as your doctor tells you.
It is important to keep taking your medicine even if you feel well. If you do not complete the full course prescribed by your doctor, all of the bacteria causing your infection may not be killed. These bacteria may continue to grow and multiply so that your infection may not clear completely or it may return.
Make sure you have enough to last over weekends and holidays.
If you forget to take it
If it is almost time to take your next dose, skip the dose you missed and take your next dose when you are meant to.
Otherwise, take it as soon as you remember, and then go back to taking your medicine as you would normally.
Do not take a double dose to make up for the dose that you missed.
This may increase the chance of you experiencing side effects.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering to take your medicine, ask your pharmacist for some hints.
If you take too much (overdose)
Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at your nearest hospital, if you think that you or anyone else may have taken too much of this medicine. Do this even if there are no signs of discomfort or poisoning.
You may need urgent medical attention.

If you get a sore white mouth or tongue while taking or soon after stopping amoxycillin and clavulanic acid, tell your doctor. Also tell your doctor if you get vaginal itching or discharge.
This may mean you have a fungal infection called thrush. Sometimes the use of amoxycillin and clavulanic acid allows fungi to grow and the above symptoms to occur. Amoxycillin and clavulanic acid does not work against fungi.
