1. Why am I being given INVANZ?

INVANZ contains the active ingredient Ertapenem.

INVANZ belongs to a class of antibiotics called carbapenems. It works by killing the bacteria causing your infection.

INVANZ is used to treat infections caused by bacteria (germs). These infections include:

• infections within the abdomen (stomach)
• pelvic infections
• diabetic foot infections in patients without osteomyelitis

INVANZ may also be used in patients not responding to, or unable to tolerate, other antibiotics.

Your doctor may have prescribed INVANZ for another reason.

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

2. What should I know before I am given INVANZ?

During treatment, you may be at risk of developing certain side effects. It is important you understand these risks and how to monitor for them. See additional information under Section 6. Are there any side effects?

Pregnancy

Check with your doctor if you are pregnant or intend to become pregnant.

Like most medicines, INVANZ is generally not recommended during pregnancy. However, if there is a need to consider using INVANZ during pregnancy, your doctor will discuss the possible risks and benefits to you and your unborn baby.

Breastfeeding

Talk to your doctor if you are breastfeeding or intend to breastfeed.

Like most medicines, the use of INVANZ is generally not recommended while breast-feeding. INVANZ is secreted into human milk.

Children

Do not use INVANZ in children under 3 months of age.

The safety and effectiveness in children younger than 3 months of age have not been established.

3. What if I am taking other medicines?

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

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

• Sodium valproate, used to control different types of epilepsy and mania

These medicines may be affected by INVANZ, or may affect how well it works. You may need different amounts of your medicine, or you may need to take different medicines. Your doctor will decide whether you should use INVANZ in combination with this medicine.

Check with your doctor or pharmacist if you are not sure about what medicines, vitamins or supplements you are taking and if these affect INVANZ.

4. How will I be given INVANZ?

How is it given

INVANZ can be given in two ways:

• as a slow injection into a vein, known as an intravenous infusion
• as a deep injection into a large muscle, known as an intramuscular injection.

INVANZ will be prepared and given to you by a doctor or other healthcare professional.

When is it given

• Your doctor will decide what dose and how long you will receive INVANZ. This depends on your condition and other factors, such as your kidney function. No dose adjustment is necessary if you are elderly.

If you are given too much INVANZ

As this product is administered by a doctor or healthcare professional, it is unlikely you will be given too much INVANZ.

However, if you have any concerns you should immediately:

• contact a healthcare professional, your doctor, or
• phone the Poisons Information Centre
  (by calling 13 11 26), or
• go to the Emergency Department at your nearest hospital.

You should do this even if there are no signs of discomfort or poisoning.

5. What should I know while being given INVANZ?

Things you should do

Call your doctor straight away if you:

• Develop severe diarrhoea

Do this even if it occurs several weeks after INVANZ has been stopped.

Diarrhoea may mean that you have a serious condition affecting your bowel. You may need urgent medical care.

This is because antibiotics such as INVANZ can change the type of bacteria in the bowel. As a result, this allows bacteria, normally present in the bowel and normally harmless, to multiply and cause the above symptoms.

Do not take any diarrhoea medicine without first checking with your doctor.

• develop a severe skin reaction such as painful red areas, fluid filled bumps, large blisters, or peeling layers of skin whilst being given INVANZ. You may need urgent medical care.

Remind any doctor, dentist or pharmacist you visit that you are using INVANZ.

Driving or using machines

INVANZ may cause dizziness or sleepiness in some patients. Make sure you know how you react to INVANZ before you drive a car, operate machinery or do anything else that could be dangerous if you are dizzy or sleepy.

Looking after your medicine

It is unlikely that you will be asked to store INVANZ yourself. It will usually be stored in the pharmacy or on the ward.

Getting rid of any unwanted medicine

A doctor, nurse or pharmacist will dispose of any unused INVANZ.
