What OZCEF is Used For

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

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

OZCEF belongs to a group of antibiotics called cephalosporins (ke-fa-lo-spor-ins), which are closely related to penicillins.

OZCEF works by killing the bacteria causing your infection or by stopping its growth.

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

This medicine is available only with a doctor’s prescription.

There is no evidence that OZCEF is addictive.

Before you start using OZCEF tablets

When you must not take it

Do not take OZCEF tablets if:

  • You have an allergy to OZCEF, cefaclor, other cephalosporins or any of the ingredients listed at the end of this leaflet.
Some of the symptoms of an allergic reaction may include skin rash, itching, difficulty breathing, and swelling of the face, lips or tongue.
  • You have had a serious allergic reaction to penicillins
  • The packaging is torn or shows signs of tampering
  • The expiry date on the pack has passed.
If you take this medicine after the expiry date has passed, it may not work as well (or it may make you feel sick).

Do not give OZCEF to children. The safety and efficacy of this product in children has not been established.

If you are not sure whether you should start using OZCEF, talk to your doctor.

Before you take it

You must tell your doctor:

  1. If you have any type of allergic reaction to cephalosporin medicines, penicillin medicines or any other antibiotic medicines.
You may have an increased chance of being allergic to OZCEF if you are allergic to cephalosporins or penicillins.
  1. If you have any allergies to any other medicines or any other substances, such as foods, preservatives or dyes
  2. If you have or have ever had any other health problems/medical conditions, including:
  • kidney disease
  • severe bowel conditions/disease
  • liver disease
  1. If you are pregnant or intend to become pregnant
Your doctor will discuss the risks and benefits of using OZCEF during pregnancy.
  1. If you are breast-feeding or plan to breast-feed.
Your doctor will discuss the risks and benefits of using OZCEF when breast-feeding.

If you have not told your doctor about any of the above, tell them before you start taking OZCEF.

Taking other medicines

Tell your doctor if you are taking any other medicines, including medicines that you buy without a prescription from your pharmacy, supermarket or health food shop. Some medicines may interfere with OZCEF. These include:

  • probenecid, a medicine used to treat gout or to prolong the action of certain antibiotics.
  • Magnesium- or aluminium-containing antacids, medicines used to treat stomach upsets or stomach ulcers.

These medicines may be affected by OZCEF, or may affect how well it works. You may need different amounts of your medicine, or you may need to take different medicines. Your doctor or pharmacist has more information on medicines to be careful with or avoid while taking OZCEF.

How OZCEF is taken

How much to take

Your doctor will decide what dose and how long you will receive OZCEF. This depends on your infection and other factors, such as your weight.

How to take it

Swallow the prescribed dose of OZCEF tablets whole with a full glass of water. Do not cut, crush or chew the tablets.

Keep taking this medicine for the full time of treatment, even if you begin to feel better after a few days.

If you do not complete the full course of treatment prescribed by your doctor, the 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 it as you would normally.

If you are not sure whether to skip the dose, talk to your doctor or pharmacist.

Do not take a double dose to make up for the dose that you missed.

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 Poisons Information Centre (telephone 13 11 26) or go to casualty at your nearest hospital if you think that you or anyone else may have taken too much OZCEF. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention. Keep telephone numbers of these places/services handy.

If you take too many OZCEF tablets, you may have:

  • nausea
  • vomiting
  • heartburn
  • diarrhoea

While you are using OZCEF tablets

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, pharmacist or nurse immediately. Do this even if it occurs several weeks after OZCEF 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 OZCEF, 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 OZCEF allows fungi to grow and the above symptoms to occur. OZCEF does not work against fungi.

If you become pregnant while you are taking OZCEF, tell your doctor.

If you are about to start taking any new medicine, tell your doctor and pharmacist that you are taking OZCEF.

If you have to have any blood or urine tests, tell your doctor you are taking OZCEF tablets. OZCEF may affect the results of some blood and urine tests.

Tell all the doctors, dentists and pharmacists who are treating you that you are receiving OZCEF.

Things you must not do

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

Do not use OZCEF 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 OZCEF affects you.

OZCEF generally does not cause any problems with your ability to drive a car or operate machinery. However, as with many other medicines, OZCEF may cause dizziness or tiredness in some people.

Side Effects

Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking OZCEF. Like other medicines, OZCEF can cause some side effects. If they occur, most are likely to be minor and temporary. However some may be serious and need medical attention.

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

While you are taking it

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

  • Oral thrush - white, furry, sore tongue and mouth
  • Vaginal thrush - sore and itchy vagina and/or discharge
  • Mild stomach upsets, such as feeling sick
  • Diarrhoea

Tell your doctor immediately or go to casualty at your nearest hospital if you notice any of the following:

  • fever
  • skin rashes which may be itchy
  • vomiting
  • severe diarrhoea

These are all serious side effects of OZCEF. You may need urgent medical attention.

If any of the following happen, stop using OZCEF and tell your doctor immediately or go to casualty at your nearest hospital:

  • life threatening allergic reactions which may include skin rash, itching, difficulty breathing, swelling of the face, lips or tongue
  • skin rash with joint pain and fever
  • decrease in urine volume

These are all very serious side effects of OZCEF. If you have them, you may have had a serious allergic reaction to OZCEF. You may need urgent medical attention or hospitalisation.

After finishing it

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

  • 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. You may have a serious condition affecting your bowel. OZCEF can cause bacteria which are normally present in the bowel and are normally harmless to multiply and thereby 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.

Other side effects not listed above may also occur in some patients. Tell your doctor if you notice any other effects.

Do not be alarmed by this list of possible side effects. You may not experience any of them.

After using OZCEF tablets


At home, keep your OZCEF tablets in their original packs until it is time to use them. If you take the tablets out of the pack, they may not keep well.

Keep it in a cool, dry place where the temperature stays below 25°C. Do not store it or any other medicine in the bathroom or near a sink.

Do not leave it in the car or on window sills. Heat and dampness can destroy some medicines.

Keep it where children cannot reach it. A locked cupboard at least one and a half metres above the ground is a good place to store medicines.


If your doctor tells you to stop taking OZCEF or the tablets have passed their expiry date, ask your pharmacist what to do with any tablets that are left over.
