Consumer Medicine Information (CMI)
This leaflet provides important information about using Enbrel. You should also speak to your doctor or pharmacist if you would like further information or if you have any concerns or questions about using Enbrel.
Where to find information in this leaflet:

Why am I using Enbrel?

Enbrel contains the active ingredient etanercept. Etanercept is a biotechnology-derived protein that works by binding to and inactivating Tumour Necrosis Factor (TNF), a naturally occurring chemical in your bloodstream that contributes to pain and swelling in the joints.
Enbrel is used in the treatment of specific inflammatory joint or skin conditions by reducing the pain and swelling of rheumatoid arthritis and psoriasis, helping to treat the skin lesions of psoriasis and psoriatic arthritis, and improving the condition of patients with ankylosing spondylitis, non-radiographic axial spondyloarthritis (nr-AxSpA) and juvenile idiopathic arthritis.
Your doctor may have prescribed Enbrel for another reason. Ask your doctor if you have any questions about why Enbrel has been prescribed for you.

What should I know before I use Enbrel?

Always check the ingredients to make sure you can use this medicine.

2. you have, or are at risk of developing, sepsis (blood poisoning), or long-term or localised infection (for example, leg ulcers).

Sepsis is a serious infection causing fever, headache, joint aches and pains, sore or weak muscles, and increased heart rate. Enbrel can affect your body's ability to fight a serious infection.
If you are not sure whether you have a serious infection, check with your doctor.

4. the packaging is torn or shows signs of tampering

5. the expiry date printed on the pack has passed.

If you use Enbrel after the expiry date has passed, it may have no effect at all, or worse, have an entirely unexpected effect.

Check with your doctor if you:

have any allergies to:
latex (the needle cover of the pre-filled syringe, dose-dispenser cartridge, auto-injector and the rubber closure of the diluent syringe (vial presentation) contain dry natural rubber),
any other medicines,
any other substances, such as foods, preservatives or dyes.

If you are not sure whether you should start taking this medicine, talk to your doctor.
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 and breastfeeding

Check with your doctor if you are pregnant or intend to become pregnant.
The effects of Enbrel in pregnant women are not well understood, therefore Enbrel should only be used during pregnancy if clearly needed. If you become pregnant while using Enbrel, contact your doctor. Your doctor will help you to decide whether the benefits of treatment outweigh the potential risk to your baby.
Talk to your doctor if you are breastfeeding or intend to breastfeed.
Enbrel passes through breast milk. Therefore, if you are breastfeeding, you should discuss with your doctor whether to stop breastfeeding or stop using Enbrel.

Use in Children

Enbrel is not currently recommended for use in children under 2 years of age as it has not been tested in children under 2 years.

Live vaccines, such as oral polio vaccine, should not be given while receiving Enbrel.
This medicine is available only with a doctor's prescription.
Enbrel is not addictive.

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 may interfere with Enbrel and affect how it works.
Medicines that increase risk of side effects when used with Enbrel:

How do I use Enbrel?

Your doctor will tell you how to inject Enbrel. A different site should be used for each new injection. Each new injection should be given at least 3 cm from an old site.

How much to use

Adults
The recommended dose for adults is 50 mg per week, injected under the skin. This can be given as either a single 50 mg injection once weekly, or two separate 25 mg injections, 3-4 days apart. Your doctor may determine a different frequency at which to inject Enbrel.
If you are being treated for psoriasis, your doctor may prescribe a higher dose of Enbrel when you first begin your treatment.
If you are being treated for nr-AxSpA and Enbrel has no effect on your condition within 12 weeks, your doctor may tell you to stop using this medicine
Follow the instructions provided and use Enbrel until your doctor tells you to stop.
Children
The appropriate dose and frequency of dosing for children and teenagers will depend on body weight and the disease. Your child's doctor will provide detailed directions for preparing and measuring the appropriate dose for your child.
For juvenile idiopathic arthritis, the recommended dose is 0.8 mg of Enbrel per kg bodyweight (up to a maximum of 50 mg) given once weekly. Enbrel may also be given twice weekly at a dose of 0.4 mg of Enbrel per kg bodyweight (up to a maximum of 25 mg).
For psoriasis patients, the recommended dose is 0.8 mg of Enbrel per kg bodyweight (up to a maximum of 50 mg) given once weekly. If Enbrel has no effect on the child's condition after 12 weeks, your doctor may tell you to stop using this medicine.

When to use Enbrel

Enbrel should be used at the same time each week or at the same time every 3-4 days as directed by your doctor.

How to use Enbrel

Your doctor will supervise and advise you on how to use Enbrel when you first start. If your doctor thinks it is appropriate, they can train you on how to self-inject Enbrel.
Enbrel should be administered according to the instructions provided in the Instructions for Use leaflet included with the medicine and the user manual provided with the SmartClic injection device for the dose-dispenser cartridge.
Powder for injection:
Enbrel powder for injection contains no additives that would prevent the growth of bacteria once the powder is dissolved. For this reason, the vial should not be stored for more than 6 hours after dissolving the powder with the diluent provided.
Solution for injection only:
After allowing the Enbrel solution to reach room temperature (approximately 15 to 30 minutes), immediate use is recommended.
Each vial or syringe of Enbrel is for single use only, in one patient only. Discard any residue.
Dose-dispenser cartridge for use in the SmartClic injection device only:
After allowing the Enbrel dose-dispenser cartridge to reach room temperature (approximately 30 minutes), immediate use is recommended.
Each dose-dispenser cartridge (for use in SmartClic injection device) is for single use in one patient only.
The SmartClic injection device is supplied separately by the doctor who prescribed Enbrel to you, or by contacting Pfizer (www.enbrel.com.au or call 1800 362 735).
Follow all directions given to you by your doctor or pharmacist carefully.
They may differ from the information contained in this leaflet.
If you are injecting Enbrel yourself, you must follow the detailed instructions provided in the leaflet inside the pack.
Enbrel is injected under the skin. When using the syringes provided with the Enbrel vial, pre-filled syringe or dose-dispenser cartridge presentations, it is important that you do not pull back on the plunger. Enbrel can be injected by your doctor, nurse, carer or by yourself.
When you have finished injecting Enbrel, discard the needle and syringe into a sharps container.
If you do not understand the instructions for injecting Enbrel found in the carton, ask your doctor or pharmacist for help.
To help you remember, use a diary to write in the days of the week you or your child should have an Enbrel injection.
You should continue to inject Enbrel for as long as your doctor recommends.
Never inject more than the dose recommended by your doctor.
If you feel that the effect of Enbrel is too strong or too weak, talk to your doctor or pharmacist.

If you forget to use Enbrel

Enbrel should be used regularly at the same time each week, or the same time every 3-4 days as agreed with your doctor. If you miss your dose at the usual time, you should inject the next dose as soon as you remember if it is within 48 hours since the scheduled dose time.
If it is almost time for your next dose i.e. within 48 hours of your next dose, skip the dose you missed and take your next dose when you are meant to.
Do not take a double dose to make up for the dose you missed.

If you use too much Enbrel

If you think that you have used too much Enbrel, you may need urgent medical attention.
You should immediately:
phone the Poisons Information Centre
(by calling 13 11 26), or
contact your doctor, or
go to the Emergency Department at your nearest hospital.
You should do this even if there are no signs of discomfort or poisoning.
Always take the labelled medicine carton with you, even if it is empty.
You may need urgent medical attention. There is very limited data on overdose with Enbrel. Ask your doctor if you have any concerns.

What should I know while using Enbrel?

Things you should do

Tell any other doctors, dentists and pharmacists who are treating you that you are using Enbrel.
Tell your doctor if Enbrel is not making your condition better.
Keep a record of the Lot number of each Enbrel pack that you use.

Call your doctor straight away if you:

Have or develop any serious infection while using Enbrel. Do not inject any more Enbrel and contact your doctor immediately.
Have any symptoms such as persistent fever, sore throat, bruising, bleeding or paleness.
These symptoms may point to the existence of a potentially life-threatening blood disorder, which may require you to stop taking Enbrel.
Remind any doctor or dentist you visit that you are using Enbrel.

Things you should not do

Do not stop using this medicine suddenly or lower the dosage without checking with your doctor.
Do not shake the solution of Enbrel after you have added the sterile water for injection. Shaking the solution will cause it to froth (create lots of bubbles). This may affect the medicine so that it may not work.

Do not give Enbrel to anyone else even if they have the same condition as you.

Do not stop using Enbrel, or lower the dosage, without checking with your doctor.

Looking after your medicine

Follow the instructions in the carton on how to take care of your medicine properly.
Keep Enbrel in a refrigerator where the temperature stays between 2°C and 8°C.
Keep it away from moisture, heat or sunlight; for example, do not store it:
in the bathroom or near a sink, or
in the car or on window sills.
Store Enbrel pre-filled syringes, auto-injectors and dose-dispenser cartridges in their cartons to protect them from light.
Heat and dampness can destroy some medicines.
If it is not possible to store Enbrel in the refrigerator, it may be stored out of the refrigerator (below 25°C) for up to 4 weeks (e.g. when travelling).
If you have stored Enbrel at room temperature for any period of time (even if returned to the refrigerator) you must use it within 4 weeks from the time you first took it out of the refrigerator, or else you must discard it.
