How to take it

Follow all directions given to you by your doctor or pharmacist carefully. They may differ from the information contained in this leaflet.

If you do not understand the instructions on the carton or bottle label, ask your doctor or pharmacist for help.

How much to take

Your doctor will tell you how much Aclor you need to take. This will depend on the type of infection you have.

How to take it

Carefully follow the instructions on the carton or bottle label.

Shake the bottle well and accurately measure the dose with a medicine measure. Shaking the bottle and using a medicine measure will make sure that you get the correct dose. You can buy a medicine measure from your pharmacist.

It does not matter if you take this medicine with or without food.

How long to take it

Continue taking Aclor for as long as your doctor tells you. It is important to complete the full course prescribed by your doctor, even if you begin to feel better after a few days. If you do not, the bacteria causing your infection may continue to grow and multiply so that your infection may not clear completely or your symptoms may return.

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

Symptoms of an overdose may include feeling sick, vomiting, upset stomach or diarrhoea.

While you are taking it

Things you must do

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

Tell any other doctors, dentists and pharmacists who are treating you that you are taking Aclor, especially if you are being started on any new medicines.

Tell your doctor, surgeon or dentist that you are taking Aclor if you are about to undergo surgery or an operation. It may affect other medicines used during surgery.

Tell your doctor if you become pregnant while you are taking this medicine.

If you are about to have any blood tests, tell your doctor that you are taking this medicine. It may interfere with the results of some tests.

Keep all of your doctor's appointments so that your progress can be checked. Your doctor may do some tests from time to time to make sure the medicine is working and to prevent unwanted side effects.

If you are diabetic, check with your doctor or pharmacist before using urine sugar tests. Aclor may cause false test results with some urine sugar tests.

Things you must not do

Do not take Aclor to treat any other complaints unless your doctor tells you to.

Do not give your medicine to anyone else even if their symptoms seem similar to yours.

Do not stop taking your medicine or change the dosage without first checking with your doctor.

Things to be careful of

Children should be careful when riding bicycles or climbing trees.
