What it is and what it is used for

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, hidradenitis suppurativa, psoriatic arthritis and axial spondyloarthritis. Cosentyx is used for the treatment of the following inflammatory diseases: • Plaque psoriasis • Hidradenitis suppurativa • Psoriatic arthritis • Axial spondyloarthritis, including ankylosing spondylitis (radiographic axial spondyloarthritis) and non-radiographic axial spondyloarthritis • Juvenile idiopathic arthritis, including enthesitis-related arthritis and juvenile psoriatic arthritis 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 adults, adolescents and children (6 years of age and older) with moderate to severe plaque psoriasis. Using Cosentyx in plaque psoriasis will benefit you by leading to improvements of skin clearance and reducing your symptoms such as scaling, itching and pain. Hidradenitis suppurativa Cosentyx is used to treat a condition called hidradenitis suppurativa, also sometimes called acne inversa or Verneuil's disease. This condition is a chronic and painful inflammatory skin disease. Symptoms may include tender nodules (lumps) and abscesses (boils) that may leak pus. It commonly affects specific areas of the skin, such as under the breasts, the armpits, inner thighs, groin and buttocks. Scarring may also occur in affected areas.

Cosentyx can reduce the number of nodules and abscesses you have and the pain that is often associated with the disease. If you have hidradenitis suppurativa you will first be given other medicines. If you do not respond well enough to these medicines, you will be given Cosentyx. Cosentyx is used in adults with hidradenitis suppurativa and can be used alone or with antibiotics. Psoriatic arthritis Cosentyx is used to treat a condition called "psoriatic arthritis". The condition is an inflammatory disease of the joints, often accompanied by psoriasis. If you have active psoriatic arthritis you will first be given other medicines. If you do not respond well enough to these medicines, you will be given Cosentyx to reduce the signs and symptoms of active psoriatic arthritis, improve physical function and slow down the damage to the cartilage and bone of the joints involved in the disease. Cosentyx is used in adults with active psoriatic arthritis and can be used alone or with another medicine called methotrexate. Using Cosentyx in psoriatic arthritis will benefit you by reducing the signs and symptoms of the disease, slowing down the damage to the cartilage and bone of the joints and improving your ability to do normal daily activities. Axial spondyloarthritis, including ankylosing spondylitis (radiographic axial spondyloarthritis) and non-radiographic axial spondyloarthritis Cosentyx is used to treat conditions called "ankylosing spondylitis" and "non-radiographic axial spondyloarthritis". These conditions are inflammatory diseases primarily affecting the spine which cause inflammation of the spinal joints. If you have ankylosing spondylitis or non-radiographic axial spondyloarthritis you will first be given other medicines. If you do not respond well enough to these medicines, you will be given Cosentyx to reduce the signs and symptoms of the disease, reduce inflammation and improve your physical function. Cosentyx is used in adults with active ankylosing spondylitis and active non-radiographic axial spondyloarthritis. Using Cosentyx in ankylosing spondylitis and non-radiographic axial spondyloarthritis will benefit you by reducing the signs and symptoms of your disease and improving your physical function. 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.
