What is in this leaflet

This leaflet answers some common questions about Keflor.

It does not contain all of the available information. It does not take the place of talking to your doctor or pharmacist.

All medicines have benefits and risks. Your doctor has weighed the risks of you taking Keflor against the benefits they expect it will have for you.

If you have any concerns about taking this medicine, talk to your doctor or pharmacist.

What Keflor is used for

Keflor is used to treat infections in different parts of the body caused by bacteria. Keflor can be used to treat infections of the:

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

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

Keflor is an antibiotic that belongs to a group of medicines called cephalosporins. These medicines work by killing the bacteria that are causing your infection.

Keflor will not work against infections caused by viruses, such as colds or flu.

Keflor is available only with a doctor's prescription.

There is no evidence that Keflor is addictive.

If you are not sure whether you should start taking this medicine, talk to your doctor.

Before you start to take it

Tell your doctor if you have had any type of allergic reaction to penicillin antibiotics. You may have an increased chance of being allergic to Keflor if you are allergic to penicillins.

Taking other medicines

Tell your doctor or pharmacist if you are taking any other medicines, including medicines that you buy without a prescription from a pharmacy, supermarket or health food shop.

Some medicines may be affected by Keflor or may affect how well Keflor works. These include:

  • anticoagulants, medicines used to prevent blood clots
  • salicylates or non steroidal anti-inflammatory drugs (NSAIDs), medicines used to treat pain or inflammation
  • probenecid, a medicine used to treat gout

    Antacids may interfere with the absorption of Keflor. To make sure there is no problem with absorption, do not take antacids within one hour of taking Keflor.

Talk to your doctor about the need for additional contraception while taking Keflor. Some antibiotics may decrease the effectiveness of some birth control pills, although this has not been shown with Keflor.

Your doctor can tell you what to do if you are taking any of these medicines.

If you are not sure whether you are taking any of these medicines, check with your doctor or pharmacist. Your doctor and pharmacist have more information on medicines to be careful with or avoid while taking Keflor.

How to take Keflor

How much to take

Your doctor will tell you how much Keflor you need to take.

This will depend on the type of infection you have.

Adults: The usual adult dose is 250 mg every 8 to 12 hours.

Children: The dose for children will depend on the child's weight. Your doctor and pharmacist will tell you how much Keflor your child should take.

How to take Keflor

Always shake the bottle well before measuring the correct amount to take.

When to take it

Take Keflor at about the same time each day. This will allow Keflor to have its best effect and also help you remember when to take it.

Keflor can be taken with or without food.

How long to take it for

Keep taking Keflor until you finish the bottle, or for as long as your doctor recommends.

Keep taking Keflor 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 prescribed by your doctor, your infection may not clear completely or your symptoms may return.

If you forget to take

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 the missed dose as soon as you remember, and then go back to taking Keflor as you would normally.

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

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

Symptoms of an overdose may include feeling sick, vomiting, upset stomach or diarrhoea.

While you are taking Keflor

Things you must do

Tell your doctor if the symptoms of your infection do not improve within a few days, or if they become worse.

Tell all the doctors, dentists and pharmacists who are treating you that you are taking Keflor, especially if you are being started on any new medicines.

Tell your doctor, surgeon, or dentist that you are taking Keflor if you are about to undergo surgery or an operation. It may affect other medicines used during surgery.

Tell your doctor if you become pregnant while you are taking this medicine.

If you have to have any blood tests, tell your doctor that you are taking Keflor. Keflor may affect the results of some tests.

If you develop itching with swelling or skin rash or difficulty breathing while you are taking Keflor, tell your doctor immediately or go to Accident and Emergency at the nearest hospital.

If you get severe diarrhoea, tell your doctor or pharmacist immediately. Do this even if it occurs several weeks after stopping Keflor. Diarrhoea may mean that you have a serious condition affecting your bowel. You may need urgent medical care. Do not take any medicines for diarrhoea without first checking with your doctor.

If you get a sore, white mouth or tongue while taking or soon after stopping Keflor, 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 Keflor allows fungi to grow and the above symptoms to occur. Keflor does not work against fungi.

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

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.

Things you must not do

Do not stop taking Keflor or lower the dose because you are feeling better, unless advised by your doctor. If you do not complete the full course prescribed by your doctor, your infection may not clear completely or your symptoms may return.

Do not take Keflor to treat any other complaints unless your doctor tells you to.

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

Things to be careful of

Be careful driving or operating machinery until you know how Keflor affects you. Keflor generally does not cause any problems with your ability to drive a car or operate machinery. However, as with many other medicines, Keflor may cause dizziness or drowsiness in some people. If any of these occur, do not drive, operate machinery or do anything else that could be dangerous.

Children should be careful when riding bicycles or climbing trees.

Side effects

Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking Keflor. Keflor treats infections in most people, but it may have unwanted side effects in some people.

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

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

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

  • diarrhoea

  • oral thrush (white, furry sore tongue and mouth)

  • watery and severe diarrhoea, which may also be bloody
  • severe stomach cramps
  • fever, in combination with one or both of the above.

Do not take any diarrhoea medicine without first checking with your doctor. You may have a serious condition affecting your bowel, requiring urgent medical attention.

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

  • swelling of the liver
  • inflammation of the kidney.
