What is in this leaflet

This leaflet answers some common questions about TREMFYA (pronounced trem-fye-ah). It does not contain all the available information. It does not take the place of talking to your doctor, nurse or pharmacist.

All medicines have risks and benefits. Your doctor has weighed the risks of you using TREMFYA against the benefits it is expected to have for you.

If you have any concerns about using this medicine, ask your doctor, nurse or pharmacist.

Keep this leaflet. You may need to read it again.

What TREMFYA is used for

TREMFYA contains the active substance guselkumab which is a type of protein called a monoclonal antibody. This medicine works by neutralising the activity of a protein called IL-23, which is present in increased levels in people with psoriasis.

TREMFYA is used to treat adults with moderate to severe plaque psoriasis, an inflammatory condition affecting the skin and nails. TREMFYA can improve skin clearance and nail appearance and reduce symptoms of psoriasis, such as scaling, shedding, flaking, itching, pain, and burning.

Ask your doctor if you have any questions about why TREMFYA has been prescribed for you. Your doctor may have prescribed TREMFYA for another reason.

How to use TREMFYA

TREMFYA is only available on prescription.

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

TREMFYA is given by injection under your skin (subcutaneous injection). At the start of your therapy, TREMFYA may be injected by your healthcare provider. Your doctor or nurse may decide that it is right for you to learn how to inject TREMFYA yourself.

It is important not to try to inject yourself until you have been trained by a healthcare professional. If you have not been trained, please contact your healthcare provider to schedule a training session. A caregiver may also give you your TREMFYA injection after proper training.

Before use, remove the carton from the refrigerator and keep the pre-filled syringe inside the carton and allow to reach room temperature by waiting for 30 minutes. Read the “Instructions for Use” leaflet for the syringe carefully before using TREMFYA.

Janssen Immunology Nurse Support is available by calling 1800 666 845.

How much to use

Your doctor will decide how much TREMFYA you need and for how long.

  • The first dose is 100 mg (the content of 1 pre-filled syringe) by subcutaneous injection. This may be given by your doctor or nurse.
  • After the first dose, you will have the next dose 4 weeks later, and then every 8 weeks. The following doses are the same as the first dose (the content of 1 pre-filled syringe).

You should not stop using TREMFYA without speaking to your doctor first. If you stop treatment, symptoms of psoriasis may come back.

If you forget to use it

If you forget to take your TREMFYA dose, inject a dose as soon as you remember.

Then, take your next dose at your regular scheduled time

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 pharmacist, nurse or doctor.

If you use too much (overdose)

If you have received more TREMFYA than you should, or the dose has been given sooner than prescribed, immediately telephone your doctor or the Poisons Information Centre for advice, or go to Accident and Emergency at your nearest hospital.

Do this even if there are no signs of discomfort or poisoning.

You may need urgent medical attention.
