How to take this medicine

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 pack, ask your doctor or pharmacist for help.

How much to take

Your doctor will tell you the dose of Noumed Amoxicillin 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 125-250mg three times daily and may vary depending on the weight of your child.

How to take it

Take the capsules with a glass of water.

When to take it

In order for Noumed Amoxicillin 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.

Noumed Amoxicillin can be taken with or without food.

How long to take it

Continue taking Noumed Amoxicillin until you finish the capsules 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 Noumed Amoxicillin.

If you forget to take it

If it is almost time for your next dose, skip the missed dose 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 give a double dose to make up for the dose that was missed.

If you have trouble remembering to give the doses, 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 the nearest hospital, if you think that you or anyone else may have taken too much Noumed Amoxicillin.

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

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

While you are taking this medicine

Things you must do

Tell your doctor if, for any reason, you have not given the medicine exactly as directed.

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 Noumed Amoxicillin 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 Noumed Amoxicillin, 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 Noumed Amoxicillin allows fungi to grow and the above symptoms to occur. Noumed Amoxicillin does not work against fungi.

Tell your doctor if you become pregnant while taking Noumed Amoxicillin.

If you have to test your urine for sugar while you are using Noumed Amoxicillin, make sure your doctor knows which type of test you use. Noumed Amoxicillin 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 Noumed Amoxicillin.

Tell all the doctors, dentists and pharmacists who are treating you that you are taking Noumed Amoxicillin.

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 Noumed Amoxicillin to anyone else, even if they have the same condition as you.

Do not give Noumed Amoxicillin to treat any other complaints unless your doctor tells you to.

Things to be careful of
