What is Cosentyx?

Cosentyx (secukinumab) is used to treat types of plaque psoriasis, psoriatic arthritis, ankylosing spondylitis, enthesitis-related arthritis, hidradenitis suppurativa (HS), and non-radiographic axial spondyloarthritis, which are autoimmune conditions. Cosentyx is an immunosuppressant medicine that reduces the effects of a chemical substance in the body that can cause inflammation.

Cosentyx is a monoclonal antibody from a group of medicines called interleukin (IL) inhibitors that work by blocking the activity of a protein called IL-17A.  People who have autoimmune conditions have increased levels of this protein. By Cosentyx blocking the protein's activity, it reduces inflammation, pain, swelling, and skin symptoms that you may have.

What is Cosentyx used for?

Cosentyx is a FDA-approved approved medicine used to treat:

• moderate to severe plaque psoriasis that covers large or many areas of the body for patients 6 years and older, who are candidates for systemic therapy or phototherapy.
• active psoriatic arthritis (PsA) in patients 2 years of age and older. 
• active ankylosing spondylitis in adults.
• active non-radiographic axial spondyloarthritis (nr-axSpA) in adults who have objective signs of inflammation.
• active enthesitis-related arthritis (ERA) in patients 4 years of age and older. 
• moderate to severe hidradenitis suppurativa (HS) in adults.

This medicine may improve your psoriasis, psoriatic arthritis, ankylosing spondylitis, non-radiographic axial spondyloarthritis, hidradenitis suppurativa, and enthesitis-related arthritis, but it may also lower the ability of your immune system to fight infections.

To make sure you can safely use Cosentyx, tell your doctor if you have ever had:

• an active or chronic infection;

How should I use Cosentyx?

Use Cosentyx for self-administration exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Ask your doctor or pharmacist if you don't understand how to use an injection.

If you prefer to have a healthcare provider administer Cosentyx to you, it is available as a monthly, 30-minute, intravenous infusion requiring no pre-medication and no laboratory monitoring. 

Subcutaneous Cosentyx

Cosentyx for self-administration at home is injected under the skin (subcutaneous injection).

• Take the injection pen out of the refrigerator and let it reach room temperature for 15 to 30 minutes before use. Give the injection within 1 hour after removing the medicine from the refrigerator.  Do not try to warm the medication by heating it in a microwave, placing it in hot water, or through any other method. 
• Prepare an injection only when you are ready to give it. You may need to use 2 injections to get your total dose.
• The solution should be clear or light-yellow. Call your pharmacist if the liquid in your vial, pen, or syringe looks cloudy, has changed colors, or has particles in it.
• Do not shake the syringe or dosing pen.
• The injection can be given anywhere on the front of your thighs (upper leg), upper outer arms, or abdomen (stomach) except your navel and the area 2 inches (5 centimeters) around it. Do not inject into the same place two times in a row. Avoid injecting into the skin that is hard, red, bruised, swollen, tender, or affected by psoriasis. 
• Throw away a prefilled syringe or injection pen after one use, even if there is still medicine left inside.
• Do not reuse a needle or syringe. Place them in a puncture-proof "sharps" container and dispose of them following state or local laws. Keep out of the reach of children and pets.

You may get infections more easily, even serious infections. You will need frequent medical tests.
