What CEFACLOR GH is Used For

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)

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.

How CEFACLOR GH 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 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 casualty at your nearest hospital if you think that you or anyone else may have taken too much CEFACLOR GH.
