Consumer Medicine Information


This leaflet answers some common questions about Amoxycillin Sandoz.

It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.

All medicines have risks and benefits. Your doctor has weighed the risks of you taking Amoxycillin Sandoz against the benefits they expect it will have for you.

If you have any concerns about taking this medicine, ask your doctor or pharmacist.

Keep this leaflet with the medicine. You may need to read it again.


The name of your medicine is Amoxycillin Sandoz. It contains the active ingredient amoxicillin trihydrate.

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

Amoxycillin Sandoz belongs to a group of antibiotics called penicillins. These antibiotics work by killing the bacteria that are causing your infection.

This medicine can also be used to prevent certain infections.

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

Your doctor may have prescribed Amoxycillin Sandoz for another reason. Ask your doctor if you have any questions about why Amoxycillin Sandoz has been prescribed for you.

Amoxycillin Sandoz is available only with a doctor’s prescription.

Amoxycillin Sandoz is not addictive.


When you must not take it

Do not take Amoxycillin Sandoz if:

  • you have an allergy to amoxicillin, any other penicillins or any of the ingredients listed at the end of this leaflet
  • you have had a serious allergic reaction in the past to any β-lactam antibiotics (e.g. penicillins, cephalosporins, carbapenem or monobactam). These are another group of antibiotics similar to penicillins.
    Some of the symptoms of an allergic reaction may include asthma, wheezing, shortness of breath, swelling of the face, lips or tongue which may cause difficulty in swallowing or breathing, skin rash, itching or hives.

Do not take Amoxycillin Sandoz after the expiry date printed on the pack has passed.

Do not take Amoxycillin Sandoz if the packaging is torn or shows signs of tampering or if the medicine does not look right.

If you are not sure if you should start taking Amoxycillin Sandoz, contact your doctor.

How much to take

Your doctor will tell you the dose of Amoxycillin Sandoz you will need to use each day. This depends on the condition being treated and whether any other medicines are being used.

In adults the usual dosage is 250-500mg three times daily.

In children, the usual dosage is 125-250 mg three times daily and may vary depending on the weight of your child.

How to take it

Amoxycillin Sandoz Capsules:

Take the capsules with a glass of water.

Amoxycillin Sandoz Suspension:

The suspension will be prepared by your pharmacist who checks the seal prior to reconstitution. Shake the bottle well and accurately measure the dose with a measuring spoon. Your pharmacist will explain how many millilitres of suspension will be needed to receive the correct dose.

Do not use the reconstituted suspension if the colour is not off-white.

Shaking the bottle and using a measuring spoon will make sure that you get the correct dose.

When to take it

In order for Amoxycillin Sandoz to be most effective, it should be taken at regular times through the day. For example, if you are taking it three times a day, take a dose every 8 hours.

Your doctor or pharmacist can advise you on a dosing schedule if you are unsure.

Amoxycillin Sandoz can be taken with or without food.

How long to take it

Continue taking Amoxycillin Sandoz until you finish the capsules or suspension, or for as long as your doctor recommends.

Keep taking this medicine for the full course of treatment, even if you begin to feel better after a few days. If you do not complete the full course prescribed by your doctor, the infection may not clear completely or your symptoms may return.

Check with your doctor if you are not sure how long you should be taking Amoxycillin Sandoz.

If you forget to take it

If it is almost time for 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.

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

If you have trouble remembering when 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), or go to Accident and Emergency at your nearest hospital, if you think that you or anyone else may have taken too much Amoxycillin Sandoz. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

If you take too much Amoxycillin Sandoz, you may experience symptoms such as diarrhoea, nausea, vomiting or stomach cramps.


Things you must do:

If the symptoms of your infection do not improve within a few days, or if they become worse, tell your doctor.

If you get severe diarrhoea tell your doctor or pharmacist immediately. Do this even if it occurs several weeks after Amoxycillin Sandoz has been stopped.

Diarrhoea may mean that you have a serious condition affecting your bowel. You may need urgent medical care. Do not take any diarrhoea medicine without first checking with your doctor.

If you get a sore white mouth or tongue while taking or soon after stopping Amoxycillin Sandoz, 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 Sandoz allows fungi to grow and the above symptoms to occur. Amoxycillin Sandoz does not work against fungi.

Tell your doctor if you become pregnant while taking Amoxycillin Sandoz.

If you have to test your urine for sugar while you are using Amoxycillin Sandoz, make sure your doctor knows which type of test you use. Amoxycillin Sandoz may affect the results of some of these tests.

If you develop itching, swelling or a skin rash when you are taking Amoxycillin Sandoz, do not take any more Amoxycillin Sandoz and tell your doctor at once.

If you are about to be started on any new medicine, tell your doctor and pharmacist that you are taking Amoxycillin Sandoz.

Tell all the doctors, dentists and pharmacists who are treating you that you are taking Amoxycillin Sandoz.

Things you must not do

Do not stop taking your medicine because you are feeling better, unless advised by your doctor.

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.

Do not give this medicine to anyone else, even if they have the same condition as you.

Do not use this medicine to treat any other complaints, unless your doctor tells you to.

Be careful driving or operating machinery until you know how Amoxycillin Sandoz affects you. Amoxycillin Sandoz may cause tiredness or dizziness in some people. Make sure you know how you react to Amoxycillin Sandoz before you drive a car, operate machinery or do anything else that may be dangerous if you are affected.


Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking Amoxycillin Sandoz.
