Consumer Medicine Information

NOTICE: This Consumer Medicine Information (CMI) is intended for persons living in Australia. This page contains answers to some common questions about Zerbaxa. It does not contain all the information that is known about Zerbaxa. It does not take the place of talking to your doctor or pharmacist. All medicines have risks and benefits. Your doctor has weighed the risk of you using this medicine against the benefits he/she expects it will have for you. If you have any concerns about using this medicine, ask your doctor or pharmacist. Bookmark or print this page, you may need to read it again.

What ZERBAXA is used for

ZERBAXA contains two active ingredients:
Ceftolozane, an antibiotic that belongs to the group of "cephalosporins". Ceftolozane can kill many kinds of bacteria that can cause infection.
Tazobactam belongs to the group of medicines known as "beta-lactamase inhibitors". Tazobactam can help ceftolozane work against some resistant types of bacteria.
When ceftolozane and tazobactam are given together, more types of bacteria are killed.
ZERBAXA is used in adults to treat complicated abdominal and urinary system infections, including a condition called pyelonephritis.
Your doctor may have prescribed ZERBAXA for another reason. Ask your doctor if you have any questions about why ZERBAXA has been prescribed for you.
ZERBAXA is only available with a doctor's prescription.
ZERBAXA is not addictive.

Before you are given ZERBAXA

When you must not be given it

Do not have ZERBAXA:
if you are allergic to ceftolozane, tazobactam or any of the other ingredients of this medicine
if you are highly allergic to beta-lactam class antibiotics (such as penicillin), or medicines known as "cephalosporins" (e.g., cephalexin)
Some symptoms of an allergic reaction may include skin rash, itching or hives on the skin, swelling of the face, lips, tongue or other parts of the body, shortness of breath, wheezing or trouble breathing.

Before you are given it

Tell your doctor:
if you know you are, or have previously been hypersensitive to cephalosporins, penicillins or other antibacterial medicines.
if you have recently had diarrhoea, or have had diarrhoea before taking this medicine.
if you know you have difficulty fighting off infections, are receiving medicines to help fight infections, or have neutropenia (low white blood cell count).
if you have allergies to any other medicines, foods, preservatives or dyes.
Tell your doctor if you are pregnant or plan to become pregnant.
Your doctor will advise if you should receive ZERBAXA during pregnancy.
Tell your doctor if you are breast-feeding or plan to breast-feed.
Your doctor will discuss the possible risks and benefits of using ZERBAXA while you are breast-feeding.

Taking other medicines

Tell your doctor or pharmacist if you are taking any other medicines, including medicines you buy without a prescription from a pharmacy or health food shop.
Some medicines and ZERBAXA may interfere with each other, including:
probenecid (a medicine for gout)
diclofenac (a medicine to treat pain and inflammation associated with arthritis)
cimetidine (a medicine used to treat heartburn and stomach ulcers)
These medicines may increase the time it takes for tazobactam to leave your body.
Some medicines may be affected by ZERBAXA or may affect how well it works. You may need different amounts of these medicines, or you may need to be given different medicines. Your doctor will advise you.
If you have not told your doctor or pharmacist about any of the above, tell them before you receive ZERBAXA.

This medicine should not be given to children under 18 years old because there is not enough information on use in this age group.

How ZERBAXA is given

How much is given

Adults
The recommended dose is one vial of ZERBAXA (containing 1000 mg of ceftolozane and 500 mg of tazobactam) every 8 hours, which is given into one of your veins (directly into the bloodstream).
Patients with kidney problems
Your doctor may need to reduce the dose of ZERBAXA or how often you are given it. Your doctor may also want to test your blood to make sure that your treatment is at the right dose, especially if you have to take this medicine for a long time.

How is it given

Your doctor or other healthcare professional will give you this medicine through an infusion (a drip for 1 hour) into one of your veins.

How long is it given for

Treatment with ZERBAXA normally lasts between 4 and 14 days, depending on the severity and location of the infection and how your body responds to treatment.
Your doctor will determine when your treatment should be stopped.

If you are given too much (overdose)

As this product is administered by a doctor or healthcare professional, it is very unlikely that you will be given too much ZERBAXA. However, if you have any concerns, talk to your doctor or other health care professional.
