What OZCEF is Used For

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

  • ears, nose, throat and tonsils (upper respiratory tract)
  • chest and lungs (lower respiratory tract)
  • bladder and kidneys (lower urinary tract)
  • skin

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

OZCEF belongs to a group of antibiotics called cephalosporins, 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.

There is not enough information to recommend the use of this medicine for children under the age of 12 years.

These include:

  • antacids
    If you need to take an antacid, do not take it within 1 hour of taking OZCEF.

How OZCEF is taken

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 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.

When to take it

Take OZCEF at about the same time each day with food. This will have the best effect. It will also help you to remember when to take the tablets.

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:

  • sick
  • vomiting
  • upset stomach
  • diarrhoea

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.

It may affect other medicines used during surgery.

Keep all of your doctor’s appointments so that your progress can be checked. Your doctor may do some tests from time to time to make sure the medicine is working and to prevent unwanted side effects.

If you are diabetic, check with your doctor or pharmacist before using urine sugar tests. OZCEF may cause false test results with some urine sugar tests.

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.
