Consumer Medicine Information

What is in this leaflet?

This leaflet answers some common questions about CEFTAZIDIME VIATRIS.

It does not contain all 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 being given CEFTAZIDIME VIATRIS against the benefits expected for you.

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

Keep this leaflet with your medicine. You may need to read it again.


CEFTAZIDIME VIATRIS is used to treat a wide range of infections caused by bacteria. These infections may affect the chest (bronchitis or pneumonia), ears, nose, throat, bladder and urinary tract, skin and soft tissue, stomach or bones.

This medicine belongs to a group of medicines called cephalosporins.

It works by killing the bacteria that cause these infections.

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

CEFTAZIDIME VIATRIS is available only with a doctor’s prescription.

CEFTAZIDIME VIATRIS is not addictive.

Some of the symptoms of an allergic reaction may include shortness of breath; wheezing or difficulty breathing; swelling of the face, lips, tongue or other parts of the body; rash, itching or hives on the skin.

You must not be given this medicine after the expiry date printed on the pack or if the packaging is torn or shows signs of tampering.

Tell your doctor if you have allergies to any other medicines, foods, preservatives or dyes.

Tell your doctor if you have or have had any of the following medical conditions:

  • kidney problems
  • liver problems
  • colitis or any other stomach or bowel illness.

Tell your doctor if you are pregnant or plan to become pregnant. Your doctor can discuss with you the risks and benefits involved.

Tell your doctor if you are breastfeeding. CEFTAZIDIME VIATRIS is excreted in human milk in low concentrations. Therefore, it should be administered to breastfeeding women only if clearly needed.

Tell your doctor if your baby has any signs of diarrhoea or any other illness, or if you notice anything wrong.

Tell your doctor if you are prescribed some urine or blood tests or if you are going to have a blood transfusion. The results of some tests can be altered by CEFTAZIDIME VIATRIS.

Taking other medicines

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

Some medicines and CEFTAZIDIME VIATRIS may interfere with each other. These include:

  • some antibiotics called aminoglycosides
  • diuretics, also called fluid or water tablets
  • another antibiotic called chloramphenicol, since both medicines can stop each other working
  • oral contraceptives (‘the pill’).

These medicines may be affected by CEFTAZIDIME VIATRIS or may affect how well it works. You may need different amounts of your medicines, or you may need to take different medicines.

Your doctor and pharmacist have more information on medicines to be careful with or avoid while taking this medicine.
