Cosentyx is used to treat some types of autoimmune conditions. These are conditions in which your body's defence system (immune system) attacks healthy tissues, such as chronic plaque psoriasis, psoriatic arthritis and ankylosing spondylitis. Cosentyx is usually used when other treatments have not worked well. It is a type of medicine is called an interleukin (IL) inhibitor.
Cosentyx works by neutralising the activity of a protein called IL-17A, which is present at increased levels in conditions such as psoriasis, psoriatic arthritis and ankylosing spondylitis. It will reduce the inflammation and other symptoms of the condition.
In New Zealand, Cosentyx is available as a pre-filled syringe, which is given as an injection under your skin into your thigh or abdomen (belly).
