What DORIBAX is used for

DORIBAX belongs to a class of antibiotics called carbapenems. It works by killing the bacteria (germs) that cause infections in various parts of the body.

These infections include:

  • pneumonia (lung infection) that occurs in a hospital or similar setting including pneumonia that occurs when on a breathing machine
  • complicated abdominal (stomach) infections
  • complicated infections of the urinary tract including kidney and bladder infections, and cases that may have spread to the bloodstream.

DORIBAX will not work against infections caused by a bacteria known as methicillin resistant Staphylococcus aureus (MRSA). It will also not work against infections caused by viruses such as colds or the flu.

Your doctor may have prescribed this medicine for another reason.

Ask your doctor if you have any questions about why it has been prescribed for you.

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

Before DORIBAX is given

When DORIBAX must not be given

You must not be given the medicine if you have an allergy to:

  • doripenem, the active ingredient in the medicine
  • other antibiotics such as penicillins, cephalosporins or carbapenems.
    Symptoms of an allergic reaction may include rash, itching or hives on the skin, shortness of breath, wheezing or difficulty breathing, swelling of the face, lips, tongue or other parts of the body.

If you are not sure whether you should be given this medicine, talk to your doctor.

Before the medicine is given:

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

  • kidney disease. It is particularly important that your doctor knows if there is anything wrong with your kidneys or if you undergo or have undergone dialysis treatment
  • allergies to any medicines, including antibiotics
  • a stroke or history of seizures
  • diarrhoea before, during or after your treatment with the medicine. This is because you may have a condition known as colitis (an inflammation of the bowel). Do not take any medicine to treat diarrhoea without first checking with your doctor.
  • any other stomach problems.

You must tell your doctor if you:

  • are pregnant or planning to become pregnant. DORIBAX is not recommended for use during pregnancy. However, if there is a need to consider using it during pregnancy, your doctor will discuss the possible risks and benefits to you and your unborn baby.
  • are breastfeeding or wish to breastfeed. It is not known whether DORIBAX passes into breast milk. Therefore there is a possibility that the breast-fed baby may be affected. Your doctor will discuss the possible risks and benefits of using this medicine while breastfeeding.

If you have not told your doctor about any of the above, tell them before you start treatment with the medicine.

The medicine must not be given beyond the expiry date (month and year) printed on the pack.

The medicine must not be given to children or adolescents (under 18 years of age).

Taking other medicines:

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

In particular, tell your doctor if you are taking any of the following:

  • valproic acid, a medicine used to treat epilepsy or mania
  • probenecid, a medicine used to treat gout.

These medicines may be affected by DORIBAX or may affect how well it works. Your doctor can tell you what to do if you are using any of these medicines.

How much is given:

Your doctor will decide what dose you will receive and how long you should be treated. The usual dose is 500mg given every 8 hours.

How it is given:

The medicine will always be prepared and given to you as an infusion into a vein by a doctor or nurse. Your doctor or nurse can explain how the solution for infusion is prepared.

If a dose of DORIBAX is missed

If you are concerned that you have missed a dose of the medicine, talk to your doctor or nurse. It is important that you receive treatment with it as long as your doctor feels it is necessary.

If you have received too much (overdose)

As the medicine is given to you under the supervision of your doctor, it is very unlikely that you will receive too much. Your doctor or nurse will be closely observing you during this time. Talk to your doctor or nurse immediately if you are concerned that you may have been given too much of this medicine.

If at some later time you feel really unwell and you think this medicine may be responsible, immediately telephone your doctor or the Poisons Information Centre for advice, or go to Accident and Emergency at your nearest hospital.
