What is Cosentyx (secukinumab)?
Cosentyx is a medication prescribed to adults who have one or more of the inflammatory autoimmune diseases. You may use it on its own or in combination with the drug methotrexate for:
- Moderate to severe plaque psoriasis
- Active psoriatic arthritis
- Active ankylosing spondylitis, and active non-radiographic axial spondyloarthritis
Cosentyx may also be used to treat children and adolescents aged 4 years and older with active enthesitis-related arthritis.
Plaque psoriasis is a skin condition caused by a speeding up of the lifecycle of skin cells, likely triggered by your immune system. It causes cells to build upon the surface of your skin, resulting in red patches covered in silvery scales. These patches can occur in a few places or they can cover large areas of your body.
Psoriatic arthritis is a joint condition that’s related to plaque psoriasis and happens most often in people who have plaque psoriasis. It’s caused by inflammation in your joints. It can make joints stiff, swollen, and painful, and it can cause damage as cartilage and bone are lost over time. Psoriatic arthritis can affect any joint, but it’s most common in the fingers and toes.
Ankylosing spondylitis is a form of arthritis caused by inflammation in the joints of your spine and sometimes in your shoulders and hips. It can result in stiffness, pain, damage, and deformation of the joints over time.
The active ingredient secukinumab is classed as a monoclonal antibody. It reduces the amount of inflammation your immune system can cause. Your immune system triggers inflammation by releasing molecules called cytokines. Secukinumab works by binding with these cytokines. This stops the cytokines from working, reducing the amount of inflammation they can trigger.
Cosentyx is available in injection form:
- 150 mg/mL in a single-dose Sensoready pen or in a single-dose prefilled syringe
- 75 mg/0.5 mL in a single-dose prefilled syringe
- 150 mg, lyophilized powder in a single-dose vial for reconstitution
Costenyx is often prescribed after a first round of medication has proven ineffective. Cosentyx is given as an injection under your skin (a subcutaneous injection). It can be done by a doctor or nurse, or by yourself using a pre-filled syringe or a Sensoready pen.
You are advised to read the medication guide and prescribing information provided with this medicine for the drug information and patient information and always speak with your healthcare provider for medical advice about any changes to your dose so they can monitor and evaluate your condition.
