What Cefaclor GH is used for

Cefaclor GH tablets contain cefaclor monohydrate as the active ingredient.

Cefaclor GH 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.

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

Cefaclor GH belongs to a group of antibiotics called cephalosporins, which are closely related to penicillins.

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

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

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

There is no evidence that Cefaclor GH is addictive.

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

Taking other medicines

Tell your doctor or pharmacist 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 Cefaclor GH. These include:

  • Antacids:
    If you need to take an antacid, do not take it within 1 hour of taking Cefaclor GH.
  • Probenecid (eg. Pro-Cid).

These medicines may be affected by Cefaclor GH, 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 Cefaclor GH.

How to take Cefaclor GH

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 Cefaclor GH. This depends on your infection and other factors, such as your weight.

How to take it

Swallow the prescribed dose of Cefaclor GH 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 Cefaclor GH 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 Accident and Emergency at your nearest hospital if you think that you or anyone else may have taken too much Cefaclor GH. 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 Cefaclor GH tablets, you may have:

  • sick;
  • vomiting;
  • upset stomach;
  • diarrhoea.

While you are taking Cefaclor GH

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 Cefaclor GH 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 Cefaclor GH, 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 Cefaclor GH allows fungi to grow and the above symptoms to occur. Cefaclor GH does not work against fungi.

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

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

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

Tell all the doctors, surgeons or dentists and pharmacists who are treating you that you are receiving Cefaclor GH if you are about to undergo surgery or an operation.

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. Cefaclor GH may cause false test results with some urine sugar tests.

Things you must not do

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

Do not use Cefaclor GH to treat any other complaints unless your doctor tells you to.

Do not stop taking your medicine or change the dosage without checking with your doctor.

Things to be careful of

Be careful driving or operating machinery until you know how Cefaclor GH affects you.

Cefaclor GH generally does not cause any problems with your ability to drive a car or operate machinery. However, as with many other medicines, Cefaclor GH 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 Cefaclor GH.

  • sudden signs of allergy such as rash, itching or hives on the skin with swelling of the face, lips, tongue or other parts of the body, shortness of breath, wheezing or trouble breathing.

These is a very serious side effect of Cefaclor GH. If you have them, you may have had a serious allergic reaction to Cefaclor GH. You may need urgent medical attention or hospitalisation. This side effect is very rare.

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

Other side effects not listed above may also occur in some people. These include:

Some of these side effects can only be found when your doctor does tests from time to time to check your progress.

After taking Cefaclor GH


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.
