Consumer Medicine Information (CMI)

What is in this leaflet

This leaflet answers some common questions about Zejula.
It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.

You should ensure that you speak to your doctor or pharmacist to obtain the most up to date information on this medicine. You can also download the most up to date leaflet from https://www.ebs.tga.gov.au/.
Those updates may contain important information about the medicine and its use of which you should be aware.
All medicines have risks and benefits. Your doctor has weighed the risks of you taking this medicine against the benefits they expect it will have for you.
If you have any concerns about taking this medicine, ask your doctor or pharmacist.
Keep this leaflet with the medicine. You may need to read it again.

What Zejula is used for

Zejula is used in adults for the treatment of cancer of the ovary, the fallopian tubes (part of the female reproductive system that connects the ovaries to the uterus), or the peritoneum (the membrane lining the abdomen). It is used for the treatment of cancer that has:
responded to first treatment with platinum-based chemotherapy, or
come back (recurred) after the cancer has responded to previous treatment with standard platinum-based chemotherapy.
Zejula contains the active substance niraparib. Niraparib is a type of anti-cancer medicine called a PARP inhibitor. PARP inhibitors block an enzyme called poly [adenosine diphosphate-ribose] polymerase (PARP).
PARP helps cells repair damaged DNA, so blocking it means that the DNA of cancer cells cannot be repaired. This results in tumour cell death, helping to control the cancer.
Ask your doctor if you have any questions about why it has been prescribed for you.
Your doctor may have prescribed it for another purpose.
This medicine is available only with a doctor’s prescription.
There is not enough information to recommend the use of this medicine for children under the age of 18 years.

Before you take Zejula

When you must not take it

Do not take Zejula if you have an allergy to:
niraparib or any of the ingredients listed at the end of this leaflet.
Some symptoms of an allergic reaction include:
skin rash,
shortness of breath or
swelling of the face, lips or tongue, which may cause difficulty in swallowing or breathing.
Do not take Zejula if you are breastfeeding.
It is not known if Zejula passes into breast milk. If you are breastfeeding, you must stop before you start taking Zejula and you must not begin breast-feeding until 1 month after taking your last dose.
Do not take this medicine if you are pregnant or intend to become pregnant.
Zejula can harm your unborn baby and may cause loss of pregnancy (miscarriage).
If you are a woman who could become pregnant you must use reliable contraception while you are taking Zejula, and you must continue to use reliable contraception for 1 month after taking your last dose.
If you are able to become pregnant, your doctor may perform a pregnancy test before you start treatment with Zejula.
Contact your doctor straightaway if you become pregnant while you are taking Zejula.
Do not take it after the expiry date printed on the pack or if the packaging is damaged or shows signs of tampering. If it has expired or is damaged, return it to your pharmacist for disposal.

Before you start to take it

Tell your doctor or pharmacist if you have any allergies to any other medicines, foods, preservatives or dyes.
Tell your doctor if you have or have had any of the following medical conditions:
low blood counts
Zejula lowers your blood-cell counts, such as your red blood-cell count (anaemia), white blood-cell count (neutropaenia), or blood-platelet count (thrombocytopaenia). Signs and symptoms you need to look out for include fever or infection, and abnormal bruising or bleeding. Your doctor will test your blood regularly throughout your treatment.
Myelodysplastic syndrome/acute myeloid leukaemia
Rarely, low blood-cell counts may be a sign of more serious problems with the bone marrow such as ‘myelodysplastic syndrome’ (MDS) or ‘acute myeloid leukaemia’ (AML). Your doctor may want to test your bone marrow to check for these problems.
High blood pressure.
Zejula can cause high blood pressure, which in some cases, could be severe. Your doctor will measure your blood pressure regularly throughout your treatment. He or she may also give you medicine to treat high blood pressure and adjust your Zejula dose, if necessary.
Posterior Reversible Encephalopathy Syndrome (PRES)
A rare neurological side effect named Posterior Reversible Encephalopathy Syndrome (PRES) has been associated with Zejula treatment. If you have headache, vision changes, confusion or seizure with or without high blood pressure, please contact your doctor.
Tell your doctor if you are pregnant or intend to become pregnant. Zejula can harm your unborn baby and may cause loss of pregnancy (miscarriage). See ‘When you must not take it’.
If you have not told your doctor about any of the above, tell them before you start taking Zejula.

Taking other medicines

Tell your doctor or pharmacist if you are taking any other medicines, including any that you buy without a prescription from your pharmacy, supermarket or health food store.
Some medicines and Zejula may interfere with each other. These include:
medicines used to prevent rejection after an organ transplant, such as cyclosporin and tacrolimus
alfentanil, a medicine used to manage pain
ergotamine, a medicine to treat migraine
medicines used to treat mental disorders such as pimozide, quetiapine and clozapine
halofantrine, a medicine to treat malaria
theophylline, a medicine to treat asthma
ropinirole, a medicine to treat Parkinson's disease
irinotecan, a medicine to treat cancer
medicines to treat high cholesterol such as rosuvastatin, simvastatin and atorvastatin
methotrexate, a medicine used to treat cancer, rheumatoid arthritis or psoriasis
metformin, a medicine used to treat diabetes
These medicines may be affected by Zejula or may affect how well it works. You may need to use different amounts of your medicine or take different medicines.
Your doctor or pharmacist has more information on medicines to be careful with or to avoid while taking Zejula.

How to take Zejula

Follow all directions given to you by your doctor or pharmacist carefully. They may differ from the information contained in this leaflet.

Do not change the Zejula dose without talking to your doctor.

How much to take

The recommended starting dose is 2 capsules taken together once a day (total daily dose of 200 mg). For some patients, a starting dose of 300 mg (3 capsules) may be appropriate and recommended by your doctor based on clinical assessment.

How long to take it

Continue taking your medicine for as long as your doctor tells you. Your doctor will check you on a regular basis, and you will normally continue to take Zejula as long as you experience benefit, and do not suffer unacceptable side effects.

If you forget to take it

If you forget to take Zejula, take your next dose at its scheduled time. Do not take an additional dose if you miss a dose or vomit after taking Zejula.
Do not take a double dose to make up for the dose that you missed. This may increase the chance of getting an unwanted side effect.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering when to take your medicine, ask your doctor or pharmacist for hints.

If you take too much (overdose)

Immediately telephone your doctor, or the Poisons Information Centre (telephone Australia 13 11 26) or go to Accident and Emergency at your nearest hospital, if you think you or anyone else may have taken too much Zejula. Do this even if there are no signs of discomfort or poisoning.

Side effects

Bruising or bleeding for longer than usual if you hurt yourself - these may be signs of a low blood platelet count (thrombocytopaenia).
Being short of breath, feeling very tired, having pale skin, or fast heartbeat - these may be signs of a low red blood cell count (anaemia).
Fever or infection – these may be signs of a low white blood cell count (neutropenia). Decrease in white blood cell count may decrease your ability to fight infections.
