• if you are allergic to the active substance (ertapenem) or any of the other ingredients of this medicine (listed in section 6)
• if you are allergic to antibiotics such as penicillins, cephalosporins or carbapenems (which are used to treat various infections).

Talk to your doctor, nurse or pharmacist before taking INVANZ.

During treatment, if you experience an allergic reaction (such as swelling of the face, tongue or throat, difficulty in breathing or swallowing, skin rash), tell your doctor straight away as you may need urgent medical treatment.

While antibiotics including INVANZ kill certain bacteria, other bacteria and fungi may continue to grow more than normal. This is called overgrowth. Your doctor will monitor you for overgrowth and treat you if necessary.

It is important that you tell your doctor if you have diarrhoea before, during or after your treatment with INVANZ. 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.

Tell your doctor if you are taking medicines called valproic acid or sodium valproate (see Other medicines and INVANZ below).

Tell your doctor about any medical condition you have or have had including:

• Kidney disease. It is particularly important that your doctor knows if you have kidney disease and whether you undergo dialysis treatment.
• Allergies to any medicines, including antibiotics.
• Central nervous system disorders, such as localised tremors, or seizures.

Experience with INVANZ is limited in children less than two years of age. In this age group your doctor will decide on the potential benefit of its use. There is no experience in children under 3 months of age.

Tell your doctor if you are taking, have recently taken or might take any other medicines.

Tell your doctor, nurse or pharmacist if you are taking medicines called valproic acid or sodium valproate (used to treat epilepsy, bipolar disorder, migraines, or schizophrenia). This is because INVANZ can affect the way some other medicines work. Your doctor will decide whether you should use INVANZ in combination with these other medicines.

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor for advice before taking this medicine.

INVANZ has not been studied in pregnant women. INVANZ should not be used during pregnancy unless your doctor decides the potential benefit justifies the potential risk to the foetus.

Women who are receiving INVANZ should not breast-feed, because it has been found in human milk and the breast-fed baby may therefore be affected.

Do not drive or use any tools or machines until you know how you react to the medicine.

Certain side effects, such as dizziness and sleepiness, have been reported with INVANZ, which may affect some patients’ ability to drive or operate machinery.

This medicine contains approximately 137 mg sodium (main component of cooking / table salt) in each 1.0 g dose. This is equivalent to 6.85 % of the recommended maximum daily dietary intake of sodium for an adult.

If you are concerned that you may have been given too much INVANZ, contact your doctor or another healthcare professional immediately.
