Patient leaflet - Ilumetri 100 mg solution for injection in Pre-filled syringe

1. What Ilumetri is and what it is used for

Ilumetri contains the active substance tildrakizumab. Tildrakizumab belongs to a group of medicines called interleukin (IL) inhibitors.

This medicine works by blocking the activity of a protein called IL-23, a substance found in the body which is involved in normal inflammatory and immune responses and which is present at increased levels in diseases such as psoriasis.

Ilumetri is used to treat a skin condition called plaque psoriasis, in adults with moderate to severe disease. Using Ilumetri will benefit you by improvements of skin clearance and reducing your symptoms.

2. What you need to know before you use Ilumetri

Do not use Ilumetri:

  • If you are allergic to tildrakizumab or any of the other ingredients of this medicine (listed in section 6). – If you have an infection which your doctor thinks is important, for example, active tuberculosis which is an infectious disease affecting mainly the lungs.

Warnings and precautions

Talk to your doctor, pharmacist or nurse before using Ilumetri:

  • If you experience allergic reactions with symptoms such as chest tightness, wheezing, swelling of the face, lips or throat do not inject more Ilumetri and contact your doctor immediately. – If you currently have an infection or if you have long-term or repeated infections. – If you have recently had or plan to have a vaccination.

If you are not sure if any of the above applies to you, talk to your doctor, pharmacist or nurse before using Ilumetri.

Ilumetri can potentially cause serious side effects, including infections and allergic reactions. You must look out for signs of these conditions while you are taking Ilumetri.

Stop using Ilumetri and tell your doctor or seek medical help immediately if you notice any signs indicating a possible serious infection or an allergic reaction (see section 4. Possible side effects).

Children and adolescents

Ilumetri is not recommended for use in children and adolescents under 18 years of age. This is because it has not yet been evaluated in this group of patients.

Other medicines and Ilumetri

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. These include vaccines and immunosuppressants (medicines that affect the immune system).

You should not be given certain types of vaccines (live vaccines) while using Ilumetri. No data are available with the concomitant use of Ilumetri and live vaccines.
