What Brenzys is used for

Brenzys is used in adults for the treatment of:
rheumatoid arthritis
ankylosing spondylitis
non-radiographic axial spondyloarthritis (nr-AxSpA)
psoriatic arthritis
plaque psoriasis.
Tumour necrosis factor (TNF) is a naturally occurring chemical messenger in your bloodstream. TNF plays a role in causing pain and swelling in the joints. Brenzys is a biotechnology-derived protein that works by binding to TNF and preventing it from acting. This reduces the pain and swelling of rheumatoid arthritis and psoriasis, helps to treat the skin lesions of psoriasis and psoriatic arthritis, and improves the condition of patients with ankylosing spondylitis and nr-AxSpA.
Your doctor may have prescribed Brenzys for another reason. Ask your doctor if you have any questions about why Brenzys has been prescribed for you.
This medicine is available only with a doctor’s prescription.
Brenzys is not addictive.
Brenzys is not indicated for use in children less than 18 years of age. Other etanercept products are available for use in children.

Before you use Brenzys

When you must not use it

Do not use Brenzys if:
You have an allergy to Brenzys or any of the ingredients listed at the end of this leaflet.
Symptoms of an allergic reaction may include wheezing, shortness of breath, difficulty breathing, or a tight feeling in your chest, swelling of the face, lips, tongue or other parts of the body, rash, itching, hives or flushed red skin, dizziness or light-headedness.
You have, or are at risk of developing, sepsis (blood poisoning), or long-term or localised infection (for example, leg ulcer).
Sepsis is a serious infection causing fever, headache, joint aches and pains, sore or weak muscles, and increased heart rate. Brenzys 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.
You are currently taking anakinra or other similar medicines known as Interleukin-1 antagonists, or other biological medicines such as anti-TNF drugs, tocilizumab or abatacept.
The packaging is torn or shows signs of tampering.
The expiry date (EXP) printed on the pack has passed.
If you use Brenzys after the expiry date has passed, it may have no effect at all, or worse, have an entirely unexpected effect.
If you are not sure whether you should start taking this medicine, talk to your doctor.

Before you use it

Tell your doctor if:
You have any allergies to:
Any other medicines
Any other substances, such as foods, preservatives or dyes.
You are pregnant or intend to become pregnant.
The effects of Brenzys in pregnant women are not well understood, therefore the use of Brenzys is not recommended during pregnancy. Women of childbearing age are advised to use contraception to avoid falling pregnant. If you become pregnant while using Brenzys, contact your doctor.
You are breast-feeding or plan to breast-feed.
Brenzys passes through breast milk. Therefore, if you are breast-feeding, you should discuss with your doctor whether to stop breast-feeding or stop using Brenzys.
You have or have had any other medical conditions, especially the following:
Serious infection including sepsis, tuberculosis or a history of recurring infections
Low resistance to disease
Liver problems or hepatitis B or hepatitis C, viruses that affect the liver
Heart failure
Blood disorders
Are about to have major surgery
Nerve disorders including multiple sclerosis or optic neuritis (inflammation of the nerves of the eyes)
Chicken pox or have been recently exposed to chickenpox.
Live vaccines, such as oral polio vaccine, should not be given while receiving Brenzys.
Ensure that children are up to date with all vaccinations (including chicken pox) before they start treatment with etanercept.
If you have not told your doctor about any of the above, tell them before you start using Brenzys.

Taking other medicines

Tell your doctor or pharmacist if you are taking any other medicines, including any that you get without a prescription from your pharmacy, supermarket or health food shop.
Some medicines may affect the way others work. Your doctor or pharmacist will be able to tell you what to do when using Brenzys with other medicines. Brenzys may interact with other medicines such as:
Abatacept, sulfasalazine or Interleukin-1 antagonists such as anakinra. These medicines are used to treat rheumatoid arthritis and other inflammatory diseases
Cyclophosphamide, a medicine used to treat cancer or prevent transplant rejection
Some vaccines
Digoxin, a medicine used to improve the strength and efficiency of the heart, or to control the rate and rhythm of the heartbeat
Warfarin, a medicine used to thin the blood and prevent blood clots
Medicines used to treat diabetes.

How to use Brenzys

After allowing the Brenzys syringe or Auto-injector to reach room temperature (approximately 30 minutes), immediate use is recommended.
Each syringe or Auto-injector of Brenzys is for single use only, in one patient only. Discard any residue.
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 Brenzys yourself, you must follow the detailed instructions provided in the leaflet inside the pack.
Brenzys is injected under the skin. When using the syringe or Auto-injector, it is important that you do not pull back on the plunger. Brenzys can be injected by your doctor, nurse, carer or by yourself.
When you have finished injecting Brenzys, discard the syringe or Auto-injector into a sharps container.
If you do not understand the instructions for injecting Brenzys 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 should have an Brenzys injection.

How much to use

Your doctor will tell you how to inject Brenzys. A different site should be used for each new injection. Each new injection should be given at least 3cm from an old site.
The recommended dose for adults is 50 mg per week, injected under the skin. Your doctor may determine a different frequency at which to inject Brenzys. If you are being treated for psoriasis, your doctor may prescribe a higher dose of Brenzys when you first begin your treatment. If you are being treated for nr-AxSpA and Brenzys has no effect on your condition within 12 weeks, your doctor may tell you to stop using this medicine.
Brenzys is not indicated for use in children less than 18 years of age. Other etanercept products are available for use in children.

How long to take it

You should continue to inject Brenzys for as long as your doctor recommends.
Never inject more than the dose recommended by your doctor.
If you feel that the effect of Brenzys is too strong or too weak, talk to your doctor or pharmacist.

If you forget to take it

If you forget to give yourself an injection, 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 more than 48 hours since the last dose was due, wait for the next scheduled dose.
Do not use a double dose to make up for the dose that you missed.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering to use your medicine, ask your pharmacist for some hints.

If you take too much (overdose)

Immediately telephone your doctor or the Poisons Information Centre (tel 13 11 26) for advice or go to Accident and Emergency at your nearest hospital, if you think that you or anyone else may have used too much Brenzys. 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 Brenzys. Ask your doctor if you have any concerns.

While you are using Brenzys

Things you must do

Tell any other doctors, dentists and pharmacists who are treating you that you are using Brenzys.
Tell your doctor if Brenzys is not making your condition better.
If you have or develop any serious infection while using Brenzys, do not inject any more Brenzys and contact your doctor immediately.
Seek medical advice immediately if you 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 Brenzys.
Be careful driving or operating dangerous machinery until you know how it affects you.
It is not known whether Brenzys causes dizziness or drowsiness.

Things you must not do

Do not shake the Brenzys syringe or Auto-injector.
Do not give Brenzys to anyone else even if they have the same condition as you.
Do not use Brenzys to treat any other complaints unless your doctor tells you to.
Do not stop using Brenzys, or lower the dosage, without checking with your doctor.

Your condition may flare up if you reduce the dose or stop using Brenzys.

Side effects

Check with your doctor as soon as possible if you have any problems while taking Brenzys, even if you do not think the problems are connected with the medicine or are not listed in this leaflet.
Like other medicines, Brenzys can cause some side effects. If they occur, most are likely to be minor and temporary. However, some may be serious and need medical attention. The most common side effects with Brenzys are injection site reactions, infections, allergic reactions, itching, rash and fever. Please see below for more detail.
Ask your doctor or pharmacist to answer any questions you may have.
Injection site reactions
The most common side effect is a mild reaction in the area where Brenzys was injected, including:
Bleeding, swelling, pain or hardness around the injection site.
These reactions generally do not occur as often after the first month of treatment.
If you are concerned about injection site reactions, contact your doctor or pharmacist.
When injecting Brenzys, some people have developed a reaction to an injection site used before.
Infections, including colds and sinus infections, are very common.
Serious infections may occur including tuberculosis and blood poisoning.
Tell your doctor immediately if you notice any of the following:
Signs of an infection such as fever, chills, mouth ulcers or sore throat
Signs of lung disease such as breathlessness during exercise or a dry cough
Signs of soft tissue infections such as bumps or sores that do not heal, are swollen, red or have pus
Signs of nervous system disorders such as seizures, numbness or tingling throughout your body, weakness in your arms and/or legs and dizziness, or problems with your eye sight
Inflammation of the spinal cord
Inflammation of the inner eye
Inflammation of blood vessels in the skin or lymph glands
Diarrhoea or mucus or blood in your stools
Signs of an allergic reaction such as swelling of the face, lips or tongue which may cause difficulty in swallowing or breathing, or hives
Signs of lupus or lupus-like syndrome, such as weight changes, persistent rash, fever, joint or muscle pain, or fatigue
Other signs of immune system disorders such as skin rash, blisters and ulcers on the skin, in the mouth or airways
Signs of a blood disorder such as tiredness, headaches, shortness of breath when exercising, dizziness, paleness, nose bleeds, unusual bleeding or bruising or more frequent infections
Signs of heart failure such as shortness of breath, persistent cough, difficulty exercising, fast or irregular heartbeat, swelling in the legs or feet, tiredness and weakness.
These may be very serious side effects. You may need urgent medical attention or hospitalisation. These side effects are rare.
Other side effects not listed above may also occur in some patients. Tell your doctor if you notice anything else that is making you unwell.
There have been reports of some types of cancer developing in patients using Brenzys and other TNF blocking medicines. These include skin cancers, cancers that affect the lymph system called lymphoma, or affect the blood system called leukaemia. The role of Brenzys in the development of cancer is not known.
Do not be alarmed by this list of possible side effects. You may not experience any of them.

After using Brenzys


Keep Brenzys where children cannot reach it.
Keep Brenzys in a refrigerator where the temperature stays between 2°C and 8°C. Do not freeze. Do not store Brenzys or any other medicine in the bathroom or near a sink. Do not leave it in the car or on window sills. Brenzys syringes and Auto-injectors should be stored in their cartons to protect them from light.
Heat and dampness can destroy some medicines.
If it is not possible to store Brenzys in the refrigerator, it may be stored out of the refrigerator (below 25°C) for up to 4 weeks (e.g. when travelling). Do not use Brenzys if it has been exposed to high temperatures, or has been out of the refrigerator for more than 4 weeks.
