What Maxamox is used for

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

AmoxicillinAmoxicillin is an antibiotic used in the treatment of bacterial infections.

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

Maxamox is used for the treatment of chest infections.

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

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

Maxamox is available only with a doctor's prescription.

Maxamox is not addictive.

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

While you are taking Maxamox

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 develop itching, swelling, a skin rash or difficulty in breathing while you are taking Maxamox, do not take any more Maxamox and tell your doctor immediately.

If you get severe diarrhoea, tell your doctor or pharmacist immediately. Do this even if it occurs several weeks after Maxamox 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, 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 allows fungi to grow and the above symptoms to occur. Maxamox does not work against fungi.

If you become pregnant while taking Maxamox, tell your doctor immediately.

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

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

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

Do not use Maxamox 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 affects you. Maxamox may cause tiredness or dizziness in some people. Make sure you know how you react to Maxamox before you drive a car, operate machinery or do anything else that may be dangerous if you are affected.
