7. Using the MYCLIC pre-filled pen to inject Enbrel (See overleaf)

Enbrel is a medicine that is made from two human proteins. It blocks the activity of another protein in the body that causes inflammation. Enbrel works by reducing the inflammation associated with certain diseases.

In adults (aged 18 and over), Enbrel can be used for moderate or severe rheumatoid arthritis, psoriatic arthritis, severe axial spondyloarthritis including ankylosing spondylitis, and moderate or severe psoriasis - in each case usually when other widely used treatments have not worked well enough or are not suitable for you.

For rheumatoid arthritis, Enbrel is usually used in combination with methotrexate, although it may also be used alone if treatment with methotrexate is unsuitable for you. Whether used alone or in combination with methotrexate, Enbrel can slow down the damage to your joints caused by the rheumatoid arthritis and improve your ability to do normal daily activities.

For psoriatic arthritis patients with multiple joint involvement, Enbrel can improve your ability to do normal daily activities. For patients with multiple symmetrical painful or swollen joints (e.g., hands, wrists and feet), Enbrel can slow down the structural damage to those joints caused by the disease.

Enbrel is also prescribed for the treatment of the following diseases in children and adolescents

• For the following types of juvenile idiopathic arthritis when treatment with methotrexate has not worked well enough or is not suitable for them:
• Polyarthritis (rheumatoid factor positive or negative) and extended oligoarthritis in patients from the age of 2 years
• Psoriatic arthritis in patients from the age of 12 years
• For enthesitis-related arthritis in patients from the age of 12 years when other widely used treatments have not worked well enough or are not suitable for them
• Severe psoriasis in patients from the age of 6 years who have had an inadequate response to (or are unable to take) phototherapies or other systemic therapies.

Do not use Enbrel

• if you, or the child you are caring for, are allergic to etanercept or any of the other ingredients of Enbrel (listed in section 6). If you or the child experience allergic reactions such as chest tightness, wheezing, dizziness or rash, do not inject more Enbrel, and contact your doctor immediately.
• if you or the child have, or are at risk of developing a serious blood infection called sepsis. If you are not sure, please contact your doctor.
• if you or the child have an infection of any kind. If you are not sure, please talk to your doctor.

Warnings and precautions

Talk to your doctor before taking Enbrel.

• Allergic reactions: If you or the child experience allergic reactions such as chest tightness, wheezing, dizziness or rash, do not inject more Enbrel, and contact your doctor immediately.
• Infections/surgery: If you or the child develop a new infection, or are about to have any major surgery, your doctor may wish to monitor the treatment with Enbrel.
• Infections/diabetes: Tell your doctor if you or the child have a history of recurrent infections or suffer from diabetes or other conditions that increase the risk of infection.
• Infections/monitoring: Tell your doctor of any recent travel outside the European region. If you or the child develop symptoms of an infection such as fever, chills or cough, notify your doctor immediately. Your doctor may decide to continue to monitor you or the child for the presence of infections after you or the child stop using Enbrel.
• Tuberculosis: As cases of tuberculosis have been reported in patients treated with Enbrel, your doctor will check for signs and symptoms of tuberculosis before starting Enbrel. This may include a thorough medical history, a chest X-ray and a tuberculin test. It is very important that you tell your doctor if you or the child have ever had tuberculosis, or have been in close contact with someone who has had tuberculosis. If symptoms of tuberculosis (such as persistent cough, weight loss, listlessness, mild fever), or any other infection appear during or after therapy, tell your doctor immediately.
• Hepatitis B: Tell your doctor if you or the child have or have ever had hepatitis B. Your doctor should test for the presence of hepatitis B infection before you or the child begin treatment with Enbrel. Treatment with Enbrel may result in reactivation of hepatitis B in patients who have previously been infected with the hepatitis B virus. If this occurs, you should stop using Enbrel.
• Hepatitis C: Tell your doctor if you or the child have hepatitis C. Your doctor may wish to monitor the treatment with Enbrel in case the infection worsens.
• Blood disorders: Seek medical advice immediately if you or the child have any signs or symptoms such as persistent fever, sore throat, bruising, bleeding or paleness. Such symptoms may point to the existence of potentially life-threatening blood disorders, which may require discontinuation of Enbrel.
• Nervous system and eye disorders: Tell your doctor if you or the child have multiple sclerosis, optic neuritis (inflammation of the nerves of the eyes) or transverse myelitis (inflammation of the spinal cord). Your doctor will determine if Enbrel is an appropriate treatment.
• Congestive heart failure: Tell your doctor if you or the child have a history of congestive heart failure, because Enbrel needs to be used with caution under these circumstances.
• Cancer: Tell your doctor if you have or have ever had lymphoma (a type of blood cancer) or any other cancer before you are given Enbrel.

Patients with severe rheumatoid arthritis, who have had the disease for a long time, may be at higher than average risk of developing lymphoma.

Children and adults taking Enbrel may have an increased risk of developing lymphoma or another cancer.

Some children and teenage patients who have received Enbrel or other medicines that work the same way as Enbrel have developed cancers, including unusual types, which sometimes resulted in death.

Some patients receiving Enbrel have developed skin cancers. Tell your doctor if you or the child develop any change in the appearance of the skin or growths on the skin.

• Chickenpox: Tell your doctor if you or the child are exposed to chickenpox when using Enbrel. Your doctor will determine if preventive treatment for chickenpox is appropriate.
• Latex: The needle cap of the MYCLIC pen is made from latex (dry natural rubber). Contact your doctor before using Enbrel if the needle cap will be handled by, or Enbrel will be given to, someone with a known or possible hypersensitivity (allergy) to latex.
• Alcohol abuse: Enbrel should not be used for the treatment of hepatitis related to alcohol abuse. Please tell your doctor if you or the child in your care have a history of alcohol abuse.
• Wegener’s granulomatosis : Enbrel is not recommended for the treatment of Wegener’s granulomatosis, a rare inflammatory disease. If you or the child in your care have Wegener’s granulomatosis, talk to your doctor.
• Anti-diabetic medicines: Tell your doctor if you or the child have diabetes or are taking medicines to treat diabetes. Your doctor may decide if you or the child need less anti-diabetic medicine while taking Enbrel.

Children and adolescents

Vaccinations: If possible, children should be up to date with all vaccinations before using Enbrel. Some vaccines, such as oral polio vaccine, should not be given while using Enbrel. Please consult your doctor before you or the child receive any vaccines.

Enbrel should not normally be used in children with polyarthritis or extended oligoarthritis below the age of 2 years, or in children with enthesitis-related arthritis or psoriatic arthritis below the age of 12 years, or in children with psoriasis below the age of 6 years.

Other medicines and Enbrel

Tell your doctor or pharmacist if you or the child are taking, have recently taken or might take any other medicines (including anakinra, abatacept or sulfasalazine), even those not prescribed by the doctor. You or the child should not use Enbrel with medicines that contain the active substance anakinra or abatacept.

Pregnancy and breast-feeding

Enbrel should only be used during pregnancy if clearly needed. You should consult your doctor if you become pregnant, think you may be pregnant, or are planning to have a baby.

If you received Enbrel during pregnancy, your baby may have a higher risk of getting an infection. In addition, one study found more birth defects when the mother had received Enbrel in pregnancy, compared with mothers who had not received Enbrel or other similar medicines (TNF‑antagonists), but there was no particular kind of birth defect reported. Another study found no increased risk of birth defects when the mother had received Enbrel in pregnancy. Your doctor will help you to decide whether the benefits of treatment outweigh the potential risk to your baby. It is important that you tell the baby’s doctors and other healthcare professionals about the use of Enbrel during pregnancy before the baby receives any vaccine (for more information see section 2, “Vaccinations”).

Women using Enbrel should not breast-feed, since Enbrel passes into human breast milk.

Driving and using machines

The use of Enbrel is not expected to affect the ability to drive or use machines.

Enbrel contains sodium

This medicine contains less than 1 mmol sodium (23 mg) per dosage unit, that is to say essentially ‘sodium free’.

Always use this medicine exactly as the doctor has told you. Check with the doctor or pharmacist if you are not sure.

If you feel that the effect of Enbrel is too strong or too weak, talk to your doctor or pharmacist.

You have been prescribed a 50 mg strength of Enbrel. A 25 mg strength of Enbrel is available for doses of 25 mg.

Dosing for adult patients (aged 18 years or over)

Rheumatoid arthritis, psoriatic arthritis, and axial spondyloarthritis including ankylosing spondylitis

The usual dose is 25 mg given twice a week or 50 mg once a week as an injection under the skin. However, your doctor may determine an alternative frequency at which to inject Enbrel.

Plaque psoriasis

The usual dose is 25 mg twice a week or 50 mg once a week.

Alternatively, 50 mg may be given twice a week for up to 12 weeks, followed by 25 mg twice a week or 50 mg once a week.

Your doctor will decide how long you should take Enbrel and whether retreatment is needed based on your response. If Enbrel has no effect on your condition after 12 weeks, your doctor may tell you to stop taking this medicine.

Use in children and adolescents

The appropriate dose and frequency of dosing for the child or adolescent will depend on body weight and disease. Your doctor will determine the correct dose for the child and will prescribe an appropriate strength of Enbrel (25 mg or 50 mg).

For polyarthritis or extended oligoarthritis in patients from the age of 2 years, or enthesitis-related arthritis or psoriatic arthritis in patients from the age of 12 years, the usual dose is 0.4 mg of Enbrel per kg bodyweight (up to a maximum of 25 mg) given twice weekly, or 0.8 mg of Enbrel per kg of bodyweight (up to a maximum of 50 mg) given once weekly.

For psoriasis in patients from the age of 6 years, the usual dose is 0.8 mg of Enbrel per kg bodyweight (up to a maximum of 50 mg), and should be 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.

The doctor will provide you with detailed directions for preparing and measuring the appropriate dose.

Method and route of administration

Enbrel is administered by an injection under the skin (by subcutaneous injection).

Enbrel can be taken with or without food or drink.

Detailed instructions on how to inject Enbrel are provided in section 7, “Using the MYCLIC pre-filled pen to inject Enbrel”. Do not mix the Enbrel solution with any other medicine.

To help you remember, it may be helpful to write in a diary which day(s) of the week Enbrel should be used.

If you use more Enbrel than you should

If you have used more Enbrel than you should (either by injecting too much on a single occasion or by using it too frequently), talk to a doctor or pharmacist immediately. Always have the outer carton of the medicine with you, even if it is empty.

If you forget to inject Enbrel

If you forget a dose, you should inject it as soon as you remember, unless the next scheduled dose is the next day; in which case you should skip the missed dose. Then continue to inject the medicine on the usual day(s). If you do not remember until the day that the next injection is due, do not take a double dose (two doses on the same day) to make up for a forgotten dose.

If you stop using Enbrel

Your symptoms may return upon discontinuation.

If you have any further questions on the use of this medicine, ask your doctor or pharmacist.

Like all medicines, this medicine can cause side effects, although not everybody gets them.

Introduction

Step 1: Preparing for an Enbrel injection

Step 2: Choosing an injection site

Step 3: Injecting the Enbrel solution

Step 4: Disposing of the used MYCLIC pen

Introduction

The instructions below explain how to use the MYCLIC pen to inject Enbrel. Please read the instructions carefully and follow them step by step. Your doctor or nurse will tell you how to inject Enbrel. Do not attempt to administer an injection until you are sure that you understand how to use the MYCLIC pen properly. If you have questions about how to inject, please ask your doctor or nurse for help.

Diagram 1

The MYCLIC pre-filled pen

​

Step 1: Preparing for an Enbrel injection

1. Select a clean, well-lit, flat surface.
2. Gather the items that you will need for your injection, and place them on the chosen surface:
3. One MYCLIC pre-filled pen and one alcohol swab (take these from the carton of pens you keep in your refrigerator). Do not shake the pen.
4. One cotton ball or gauze
5. Check the expiry date (month/year) on the pen. If the date has passed, do not use the pen and contact your pharmacist for assistance.
6. Inspect the solution in the pen by looking through the clear inspection window. The solution should be clear or slightly opalescent, colourless to pale yellow or pale brown, and may contain small white or almost transparent particles of protein. This appearance is normal for Enbrel. Do not use the solution if it is discoloured, cloudy, or if particles other than those described above are present. If you are concerned with the appearance of the solution, then contact your pharmacist for assistance.
7. Leave the white needle cap in place and wait approximately 15-30 minutes to allow the Enbrel solution in the pen to reach room temperature. Waiting until the solution reaches room temperature may make the injection more comfortable for you. Do not warm in any other way. Always leave the pen out of sight and reach of children.

Whilst waiting for the solution in the pen to reach room temperature, read Step 2 (below), and choose an injection site.

Step 2: Choosing an injection site (see Diagram 2)

1. The recommended injection site is the middle of the front of the thighs. If you prefer, you may alternatively use the stomach area, but make sure you choose a site at least 5 cm away from the belly button (navel). If someone else is giving you the injection, the outer area of the upper arms may also be used.

Diagram 2

​

2. Each injection should be given at least 3 cm from where you last injected. Do not inject into tender, bruised or hard skin. Avoid scars or stretch marks. (It may be helpful to keep notes on the location of the previous injections.)
3. If you have psoriasis, you should try not to inject directly into any raised, thick, red, or scaly skin.

Step 3: Injecting the Enbrel solution

1. After waiting approximately 15-30 minutes for the solution in the pen to warm to room temperature, wash your hands with soap and water.
2. Clean the injection site with the alcohol swab using a circular motion, and allow it to dry. Do not touch this area again before injecting.
3. Pick up the pen, and remove the white needle cap by pulling it straight off (see Diagram 3). To avoid damaging the needle inside the pen, do not bend the white needle cap while you are removing it, and do not re-attach it once it has been removed. After removal of the needle cap, you will see a purple needle safety shield extending slightly from the end of the pen. The needle will remain protected inside the pen until the pen is activated. Do not use the pen if it is dropped with the needle cap off.

Diagram 3

​

4. Lightly pinching the skin around the injection site between the thumb and index finger of your free hand may make the injection easier and more comfortable.
5. Hold the pen at a right angle (90°) to the injection site. Push the open end of the pen firmly against the skin, so that the needle safety shield is pushed completely inside of the pen. A slight depression in the skin will be seen (see Diagram 4). The pen can only be activated when the needle shield is completely pushed inside the pen.

Diagram 4

​

6. Whilst pushing the pen firmly against the skin to ensure that the needle safety shield is fully depressed inside the pen, press the centre of the green button on top of the pen with your thumb to start the injection (see Diagram 5). On pressing the centre of the button, you will hear a click. Continue to hold the pen firmly against your skin until you hear a second click, or until 10 seconds after the first click (whichever happens first).

Note: If you are unable to start the injection as described, press the pen more firmly against your skin, then press the green button again.

Diagram 5

​

7. On hearing the second 'click'(or, if you do not hear a second 'click', after 10 seconds have passed), your injection will be complete (see Diagram 6). You may now lift the pen from your skin (see Diagram 7). As you lift the pen, the purple needle safety shield will automatically extend to cover the needle.

Diagram 6 Diagram 7

​

8. The pen's inspection window should now be completely purple, confirming that the dose has been injected correctly (see Diagram 8). If the window is not completely purple, contact your nurse or pharmacist for assistance, since the pen may not have injected the Enbrel solution completely. Do not try to use the pen again, and do not try to use another pen without agreement from your nurse or pharmacist.

Diagram 8

​

9. If you notice a spot of blood at the injection site, you should press the cotton ball or gauze over the injection site for 10 seconds. Do not rub the injection site.

Step 4: Disposing of the used MYCLIC pen

• The pen should be used once only - it should never be re-used. Dispose of the used pen as instructed by your doctor, nurse or pharmacist. Do not attempt to recap the pen.

If you have any questions, please talk to a doctor, nurse or pharmacist who is familiar with Enbrel.
