ABBOCILLIN is used to treat infections in different parts of the body caused by bacteria.

It works by killing the bacteria that are causing the infection. ABBOCILLIN will not work against infections caused by viruses such as colds or the flu. Your doctor however, may have prescribed it for another purpose. Ask your doctor (or pharmacist) if you have any questions about why ABBOCILLIN has been prescribed for you.

Tell your doctor or pharmacist if you are taking any oral contraceptive pills. You may need to use other birth control methods while you are taking ABBOCILLIN.

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 box/bottle, ask your doctor or pharmacist for help.

How much to take

Your doctor may adjust this dose depending on the type and severity of the infection.

The usual dose is 250 mg to 500mg every four to six hours for adults and older children.

How to take ABBOCILLIN

For tablets
Swallow the tablets whole with a full glass of water.

When to take it

Take your medicine at about the same time each day. Taking it at the same time each day will have the best effect. It will also help you remember when to take it.

Your medicine is best taken on an empty stomach (one hour before meals and at bedtime), unless otherwise directed by your doctor

How long to take it

Continue taking your medicine for as long as your doctor tells you.

If you forget to take it

If it almost time for your next dose, skip the dose you missed and take you next dose when you are meant to.

Otherwise, take it as soon as you remember, and then go back to taking you medicine as you would normally.

Do not take double dose to make for the dose that you missed. This may increase the chance of you getting an unwanted side effect.

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 Poison Information Centre (telephone 13 11 26) for advice, or go the Accident and Emergency at the nearest hospital, if you think that you or anyone else may have taken too much ABBOCILLIN. Do this even if there are no signs of discomfort or poisoning.

You may need urgent medical attention.

What if I am feeling better?

The whole course of antibiotics should be taken, even if you are feeling better. If you stop taking antibiotics too soon the infection may start up again because not all the infection has been killed.

If your symptoms do not improve within a few days of starting ABBOCILLIN, or if they have become worse, check with your doctor.

While you are using it

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 with swelling of skin rash or difficulty breathing while you are taking ABBOCILLIN do not take any more and contact your doctor immediately.

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

If you become pregnant while taking ABBOCILLIN tell your doctor.

If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking ABBOCILLIN.

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.

Tell any other doctors, dentists, and pharmacists who treat you that you are taking this medicine.

Things you must not do

Do not stop taking ABBOCILLIN 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 take ABBOCILLIN to treat any other complaints unless your doctor tells you to.

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

Things to be careful of

Be careful when drinking alcohol while you are taking this medicine.

Take care while driving or operating machinery until you know how ABBOCILLIN affects you.

Side effects

Tell your doctor or pharmacist as soon as possible if you do not feel well while you are using ABBOCILLIN. It helps most people with infections, but it may have some unwanted side effects in a few people.

All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical attention if you get some of the side effects.

Do not be alarmed by the following lists of side effects. You may not experience any of them.

Ask your doctor or pharmacist to answer any questions you may have.

Tell your doctor or pharmacist if you notice any of the following and they worry you:

  • skin rash
  • nausea & vomiting
  • black hairy tongue
  • diarrhoea
  • epigastric distress
  • difficulty in breathing

If any of the following happen, tell your doctor immediately or go the Accident and Emergency at your nearest hospital:

  • shortness of breath
  • wheezing or difficulty breathing
  • swelling of the face, lips, tongue or other parts of the body
  • rash, itching or hives on the skin
  • nausea, vomiting and diarrhoea.

The above list includes very serious side effects. You may need urgent medical attention or hospitalisation. These side effects are very rare. Other side effects not listed above may also occur in some people.

Tell your doctor or pharmacist if you notice anything that is making you feel unwell.

Tell you doctor immediately if you notice any of the following side effects, particularly if they occur several weeks after stopping treatment with ABBOCILLIN.

  • Severe abdominal cramps or stomach cramps
  • Watery and severe diarrhoea, which may also be bloody
  • Fever, in combination with one or both of the above

These are rare but serious side effects. ABBOCILLIN can change bacteria, which is normally present in the bowel and normally harmless, to multiply and therefore cause the above symptoms. You may need urgent medical attention. However, this side effect is rare.

Do not take any diarrhoea medicine without first checking with your doctor.
