What amoxycillin is used for

The name of your child’s medicine is GenRx Amoxycillin Suspension. It contains the active ingredient, amoxycillin.

It is an antibiotic which used to treat infections in different parts of the body caused by bacteria.

Amoxycillin can also be used to prevent infection.

Amoxycillin will not work against infections caused by viruses such as colds or the flu.

How it works

Amoxycillin is an antibiotic that belongs to a group of medicines called penicillins (pen-i-sil’lins). These antibiotics work by killing the bacteria that are causing your child’s infection.

Ask your doctor if you have any questions about why this medicine has been prescribed for your child. Your doctor may have prescribed amoxycillin for another reason.

This medicine is available only with a doctor’s prescription.

There is no evidence that this medicine is addictive.

Use in children

Amoxycilin Suspension is the most suitable form of amoxycillin to give to children.

If you are an adult and you are taking this suspension you should also read the leaflet about Amoxycillin capsules.

Before your child takes amoxycillin

When your child must not take it

This medicine must not be taken if your child has had an allergic reaction to:

  • amoxycillin
  • other penicillins or cephalosporins
  • any of the ingredients listed near the end of this leaflet.

Symptoms of an allergic reaction may include shortness of breath, wheezing or difficulty breathing, swelling of the face, lips, tongue or other parts of the body, muscle pain or tenderness or joint pain or rash, itching or hives on the skin.

This medicine must not be taken after the expiry date (EXP) printed on the pack. If this medicine is taken after the expiry date has passed, it may not work as well.

This medicine must not be taken if the packaging is torn or shows signs of tampering or if it does not look quite right.

If it has expired or is damaged, return it to your pharmacist for disposal.

If you are not sure whether your child should start taking amoxycillin, talk to your doctor or pharmacist.

Before your child starts to take it

Tell your doctor if:

  1. Your child is allergic to:
    – any other medicines
    – any other substances, such as foods, preservatives or dyes
  2. Your child has ever had an allergic reaction (such as a rash) to any antibiotics in the past.
  3. Your child has or has had any medical conditions, especially the following:
    – glandular fever (mononucleosis)
    – blood disorders such as leukaemia
    – liver or kidney problems
  4. Your child’s urine has to be tested for sugar levels while taking amoxycillin.

Amoxycillin will produce false positive results when some of these tests are used. Your doctor will help you to identify the correct test.

If you have not told your doctor about any of the above, tell them before your child starts taking amoxycillin.

Taking other medicines

Tell your doctor or pharmacist if your child is taking any other medicines, including any that you buy without a prescription from your pharmacy, supermarket or health food shop. Some medicines and amoxycillin may interfere with each other. These include:

  • medicines used to treat gout (eg probenecid or allopurinol)
  • other antibiotics (e.g. tetracyclines)

These medicines may be affected by amoxycillin, or may affect how well it works. Your child may need different amounts of medicine, or he/she may need to take different medicines.

Your doctor and pharmacist will advise you. They will tell you if
your child is taking any of these medicines. They may also have more information on medicines to be careful with or avoid while taking amoxycillin.

How to give this medicine to your child

Follow all directions from your doctor or pharmacist carefully. They may be different to the information in this leaflet.

If you do not understand any written instructions, ask your doctor or pharmacist for help.

How much to give

Your doctor or pharmacist will tell you how much liquid you will need to give. This depends on your child’s condition and whether or not they are taking any other medicines.

The usual dose of amoxycillin suspension is one dose three times a day. The dose may vary according to your child’s weight.

How to give it

Shake the suspension in the bottle well before measuring out the dose in a suitable measure. Make sure that the whole dose is swallowed each time.

When to give it

Give it at about the same time each day. Giving the medicine at the same time each day will have the best effect. It will also help you remember when to give it.

Space the doses as evenly as possible throughout the day.

For example, if your child is taking amoxycillin three times a day, give a dose about every eight hours.

Amoxycillin can be taken with or without food. The effects of
amoxycillin are not changed by food.

How long to give it for

Continue giving amoxycillin to your child until the course is finished or until your doctor says so.

Do not stop giving this medicine to your child because he/she is feeling better. If the full course prescribed by your doctor is not completed, the infection may not clear completely or it may return.

Make sure you have enough to last over weekends and holidays.

If you forget to give it

If it is almost time for your child’s next dose, skip the dose they missed and give the next dose when you are meant to.

Otherwise, give it as soon as you remember, and then go back to giving the doses as you would normally.

Do not give a double dose to make up for the dose that was missed. This may increase the chance of your child getting an unwanted side effect.

If you are not sure what to do, ask your doctor or pharmacist.

If you have trouble remembering to give the doses, ask your pharmacist for some hints.

If your child takes too much (overdose)

Immediately telephone your doctor or the Poisons Information Centre (Tel: 13 11 26 for Australia) or go to the Accident and Emergency Department at the nearest hospital, if you think that your child or anyone else may have taken too much amoxycillin.

Do this even if there are no signs of discomfort or poisoning. Your child may need urgent medical attention.

If your child takes too much amoxycillin, they may feel sick or get diarrhoea.

While your child is taking amoxycillin

Things you must do

Tell your doctor if:

  1. The symptoms of your child’s infection do not improve within a few days, or if they become worse.
  2. Your child develops itching with swelling or skin rash or difficulty breathing. Stop
    giving this medicine and contact your doctor immediately.
  3. Your child gets severe diarrhoea. Tell your doctor, pharmacist or nurse immediately. Do this even if it occurs several weeks after your child stopped taking amoxycillin.

Diarrhoea may mean that your child has a serious condition affecting the bowel. They may need urgent medical care.

Do not give any anti-diarrhoea medicine without first checking with your doctor.

  1. Your child gets a sore white mouth or tongue while taking or soon after stopping amoxycillin, or if your daughter gets vaginal itching or discharge

This may mean they have a fungal infection called thrush. Sometimes the use of amoxycillin allows fungi to grow and the above symptoms to occur. Amoxycillin does not work against fungi.

  1. Your child is about to have any blood tests.
  2. Your child is about to start taking any other new medicine.

Tell any other doctors, dentists, and pharmacists who are treating your child that they are taking amoxycillin.

Keep any appointments with your doctor. Your doctor may want to do tests to make sure the medicine is working and to prevent side effects.

Things you must not do

Do not stop giving your child this medicine because they are feeling better, unless advised by your doctor. If your child does 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 child’s infection may not clear completely or it may return and be more difficult to treat.

Do not give this medicine to
anyone else, even if their symptoms seem similar to your child’s.

Do not give this medicine to treat any other complaints unless your doctor or pharmacist tells you to.

Do not stop giving your child this medicine, or change the dosage, without checking with your doctor.

Side effects of amoxycillin

All medicines may have some unwanted side effects. Sometimes they are serious, but most of the time, they are not. Your doctor has weighed the risks of using this medicine against the benefits they expect it will have for your child.

Tell your doctor or pharmacist as soon as possible if your child does not feel well while they are taking amoxycillin.

Ask your doctor or pharmacist to answer any questions you may have.

After taking this medicine


Keep amoxycillin suspension in its original bottle until it is time to give it. If you put the suspension in a different container it may not keep well.
