Cosentyx® 75 mg solution for injection in pre‑filled syringe – patient leaflet, side effects, dosage

1. What Cosentyx is and what it is used for

Cosentyx contains the active substance secukinumab. Secukinumab is a monoclonal antibody which belongs to a group of medicines called interleukin (IL) inhibitors. This medicine works by neutralising the activity of a protein called IL-17A, which is present at increased levels in diseases such as psoriasis, psoriatic arthritis and axial spondyloarthritis.

Cosentyx is used for the treatment of the following inflammatory diseases:

• Paediatric plaque psoriasis

• Juvenile idiopathic arthritis, including enthesitis-related arthritis and

  juvenile psoriatic arthritis

Paediatric plaque psoriasis

Cosentyx is used to treat a skin condition called “plaque psoriasis”, which causes inflammation affecting the skin. Cosentyx reduces the inflammation and other symptoms of the disease. Cosentyx is used in adolescents and children (6 years of age and older) with moderate to severe plaque psoriasis.

Using Cosentyx in plaque psoriasis will benefit you (or your child) by leading to improvements of skin clearance and reducing symptoms such as scaling, itching and pain.

Juvenile idiopathic arthritis, including enthesitis‑related arthritis and juvenile psoriatic arthritis

Cosentyx is used in patients (6 years of age and older) to treat conditions of the juvenile idiopathic arthritis categories called “enthesitis-related arthritis” and “juvenile psoriatic arthritis”. These conditions are inflammatory diseases affecting the joints and the places where tendons join the bone.

Using Cosentyx in enthesitis-related arthritis and juvenile psoriatic arthritis will benefit you (or your child) by reducing the symptoms and improving your (or your child’s) physical function.

2. What you need to know before you (or your child) use Cosentyx

Do not use Cosentyx:

• if you (or your child) are allergic to secukinumab or any of the other

  ingredients of this medicine (listed in section 6).

  If you think you (or your child) may be allergic, ask your doctor for

  advice before using Cosentyx.

• if you (or your child) have an active infection which your doctor thinks

  is important (for example, active tuberculosis).
