The name of your medicine is Maxamox Suspension. It contains the active ingredient amoxycillin trihydrate.

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

Maxamox Suspension 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.

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

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

Maxamox Suspension is available only with a doctor's prescription.

Maxamox Suspension is not addictive.

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

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

How much to take

Your doctor will tell you the dose of the suspension 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 250-500 mg three times daily.

In children, the dosage may vary depending on the condition being treated and the weight of the child.

How to take it

The suspension will be prepared by your pharmacist. 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. Shaking the bottle and using a measuring spoon will make sure that you get the correct dose.

When to take it

In order for Maxamox Suspension 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.

Maxamox Suspension can be taken with or without food.

How long to take it

Continue taking the suspension until it is finished 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 Maxamox Suspension. Your doctor may recommend that you continue taking Maxamox suspension for two to three days after the symptoms of your infection have disappeared.

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

If you take too much Maxamox Suspension, 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 Maxamox Suspension 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 Maxamox Suspension, 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 Maxamox Suspension allows fungi to grow and the above symptoms to occur. Maxamox Suspension does not work against fungi.

Tell your doctor if you become pregnant while taking Maxamox Suspension.

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

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

Tell all the doctors, dentists and pharmacists who are treating you that you are taking Maxamox Suspension.

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.

Things to be careful of

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