1. what invanz is and what it is used for

INVANZ contains ertapenem which is an antibiotic of the beta-lactam group. It has the ability to kill a wide range of bacteria (germs) that cause infections in various parts of the body.

INVANZ can be given to persons 3 months of age and older.

Treatment:

Your doctor has prescribed INVANZ because you or your child has one (or more) of the following types of infection:

Infection in the abdomen
Infection affecting the lungs (pneumonia)
Gynaecological infections
Skin infections of the foot in diabetic patients.

Prevention:

Prevention of surgical site infections in adults following surgery of the colon or rectum.

2. what you need to know before you are given invanz

Do not use INVANZ

– 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).

Warnings and precautions

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.

Children and adolescents (3 months to 17 years of age)

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.

Other medicines and INVANZ

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.

Pregnancy and breast-feeding

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.

Driving and using machines

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.

INVANZ contains sodium

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.

3. how to use invanz

INVANZ will always be prepared and given to you intravenously (into a vein) by a doctor or another healthcare professional.

The recommended dose of INVANZ for adults and adolescents 13 years of age and older is 1 gram (g) given once a day. The recommended dose for children 3 months to 12 years of age is 15 mg/kg given twice daily (not to exceed 1 g/day). Your doctor will decide how many days’ treatment you need.

For prevention of surgical site infections following surgery of the colon or rectum, the recommended dose of INVANZ is 1 g administered as a single intravenous dose 1 hour before surgery.

It is very important that you continue to receive INVANZ for as long as your doctor prescribes it.

If you are given more INVANZ than you should

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

If you miss a dose of INVANZ

If you are concerned that you may have missed a dose, contact your doctor or another healthcare professional immediately.
