What are the aims of this leaflet?

This leaflet has been written to help you understand more about tralokinumab. It explains how it works, why you have been chosen for treatment and possible side effects. It gives answers to some frequently asked questions and tells you where you can find more information.

What is tralokinumab and how does it work?

Tralokinumab is a medicine that has been designed to treat an inflammatory disease called atopic eczema (also known as atopic dermatitis).

Tralokinumab is a biologic medicine, which means it is made using living cells and acts on the immune system. There are numerous proteins in the body  and immune system called ‘cytokines’ which affect inflammation. Tralokinumab blocks a cytokine called ‘interleukin-13’ (IL-13). By doing this, tralokinumab controls the inflammation in the body and eases the symptoms of atopic eczema.

Why have I been selected for treatment with tralokinumab?

National guidelines recommend tralokinumab for the treatment of moderate to severe atopic eczema in adults who have not improved with at least one tablet medication (for example, ciclosporin, methotrexate, azathioprine or mycophenolate), or when these cannot be used.

Are there any alternatives to tralokinumab? 

Most patients will have tried at least one of the tablet medications listed above before being offered tralokinumab. For adult patients there are other treatment options such as baricitinib, abrocitinib and upadacitinib. For children 12 years and over abrocitinib and upadacitinib may be suitable alternatives.

Will tralokinumab cure my skin condition? 

Treatments for atopic eczema usually reduce your symptoms and keep the condition under control, but do not cure it.

Changes in symptoms may be seen within 2 weeks. Studies show that after 16 weeks of tralokinumab, 80% of people had seen some effect. 

How is tralokinumab given?

Tralokinumab is given as an injection into the fat under your skin (subcutaneously), using a pre-filled syringe. A healthcare professional will teach you how to use this yourself. You should also read the instructions in the package insert.

Injections are given under the skin of the stomach or thighs, except for 5cm around the tummy button. If somebody else is giving you the injection, then it can be given in the upper outer arms. You should wait 30 minutes after removing the syringe from the fridge for it to reach room temperature. You will be provided with a special bin to dispose of your syringe safely.

The first dose is 600mg. The pre-filled syringe contains either 150mg or 300mg, which your doctor will discuss with you. If you have 150mg syringes, then four injections should be given; if you have 300mg syringes then two injections should be given.

After this, the dose is 300mg every 14 days. If you have 150mg syringes, then two injections should be given; if you have 300mg syringes then one injection should be given.

What should I do if I miss a dose?

If a dose is missed, the missed dose should be given as soon as possible, and you should contact your dermatology team about what to do next.

How do I store tralokinumab?

Tralokinumab injections must be stored in a fridge (between 2 to 8°C) in their original carton to protect them from light. The expiry date of each syringe should be checked prior to use.

Once tralokinumab has been removed from the fridge, it should not be put back. It must either be used within 14 days or disposed of in the bin provided. Information about sharps bin disposal can be found on your local council’s website. Medication that has been warmed above 25°C should not be used.

Can I travel abroad while taking tralokinumab? 

Please discuss with your dermatologist if you are planning to travel abroad. It is important to keep the tralokinumab at the correct temperature.

Depending on where you are travelling, you may also need to take precautions against infections with parasitic worms, as tralokinumab might affect your body’s immune response to this kind of infection. 

Can I still use topical steroids? 

Yes, prescribed topical steroid creams and ointments can still be used while taking tralokinumab. For many patients topical steroid use will become less frequent over time and may just be needed for an occasional flare of eczema.

What are the common side effects of tralokinumab?

Very common side-effects (affecting more than 1 in 10 people) are upper respiratory tract infections (sore throat, runny nose, mild cough).

Common side-effects (affecting up to 1 in 10 people) include a mild reaction around the injection area (redness, swelling, itching and pain).

Patients can also commonly (affecting up to 1 in 10 people) develop eye-related side effects. These are usually in the form of mild conjunctivitis (redness, itching) which is treated without needing to stop tralokinumab. There can be other uncommon eye side effects for which you may be referred to an ophthalmologist (eye specialist). Talk to your doctor or another healthcare professional promptly if you have any new or worsening eye problems. These can include eye watering, itching, redness, swelling, eye dryness, a feeling of gritty eyes, or a sensation of a foreign body in the eye. Seek emergency medical advice if you experience significant eye pain, or changes in your vision. 

What are the rare side effects of tralokinumab?

Severe allergic reactions are very rare. If you develop a swollen face/tongue, difficulty breathing, feeling lightheaded, itching all over, widespread rash, fever, and joint pain, you should dial 999 or immediately go to a hospital Accident & Emergency department. Afterwards, you should make sure that your dermatologist and GP have been informed of the reaction and you should stop using tralokinumab.

What happens before starting treatment? 

Before you start taking tralokinumab, you will have a consultation with your dermatologist/dermatology team including a clinical examination. It is important to tell your dermatologist if you:

  • Have any current or past parasitic worm infections
  • Have any previous eye problems such as eye infections
  • Have any allergies (see below)
  • Are pregnant or plan to become pregnant, or are breastfeeding or plan to breastfeed (see below)
  • Are due to receive any vaccinations (see below)

Your dermatologist will discuss your individual situation with you and explain more about how these factors may affect your treatment.

I have an allergy. Can I take tralokinumab? 

People with allergies should notify their dermatology team or pharmacist before using tralokinumab. 

Does tralokinumab affect pregnancy and breastfeeding?

The effects of tralokinumab in pregnant women are not known. It is also not known whether tralokinumab passes into breast milk. As tralokinumab remains in the body after a dose is given, it is important to have a discussion with your doctor about using tralokinumab if you are considering pregnancy and/or breastfeeding.

Can I have immunisations (vaccinations) whilst on tralokinumab?

Patients using tralokinumab should not be given any live or live attenuated vaccines, such as those for chickenpox/shingles, rubella (German measles), yellow fever and some polio vaccines. It is recommended that patients should be brought up to date with such vaccinations before treatment. ’Inactivated’ or ‘non-live’ vaccines can be used. You should always make sure healthcare professionals are aware that you are taking tralokinumab when receiving a vaccination. Further advice is available on the BAD website with a patient information leaflet on immunisations).

What will happen if I need an operation or dental surgery? 

There is no data to suggest that tralokinumab should be stopped before surgical or dental procedures. Stopping tralokinumab increases the risk of skin flare-ups. Please discuss this with your doctor or dentist.

Can I drink alcohol while taking tralokinumab?

There is no known interaction between alcohol and tralokinumab. UK guidelines recommend all people drink no more than 14 units of alcohol per week.

Can I take other medicines at the same time as tralokinumab?

Most prescribed medicines are safe to take with tralokinumab. However, it is important that your GP and other healthcare professionals involved in your care are aware that you are taking it.

Where can I get more information about tralokinumab?

This information sheet does not list all the side effects of tralokinumab. If you wish to find out more about tralokinumab, please speak to your doctor, specialist nurse or pharmacist. For further details, look at the drug information sheet which comes as an insert with your tralokinumab.
