What is Cosentyx?

Cosentyx is an immunosuppressant that reduces the effects of a chemical substance in the body that can cause inflammation.

Cosentyx is used to treat adults and children 6 years of age and older with moderate to severe plaque  psoriasis  (raised, silvery flaking of the skin) that involves large areas or many areas of the body, and who may benefit from using injections or pills (systemic therapy) or phototherapy (treatment using ultraviolet or UV light alone or with systemic therapy).

Cosentyx is also used to treat adults with active  ankylosing spondylitis , active  psoriatic arthritis , and active  non-radiographic axial spondyloarthritis .

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


You may get infections more easily while using Cosentyx. Call your doctor right away if you have signs of infection such as: fever, chills, sweats, muscle aches, skin sores, stomach pain,  diarrhea , burning when you urinate,  weight loss , cough, shortness of breath, or a cough with red or pink mucus.

Tell your doctor if you have an active infection or have ever been diagnosed with tuberculosis or inflammatory bowel disease before using Cosentyx.

Before using this medicine

You should not use Cosentyx if you are allergic to secukinumab.

Tell your doctor if you’ve had or been exposed to  tuberculosis , or if you recently traveled. Some infections are more common in certain parts of the world, and you may have been exposed during travel.

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

  • an active or chronic infection;
  • inflammatory bowel disease  ( Crohn’s disease  or  ulcerative colitis );
  • an allergy to latex; or
  • if you currently have signs of infection such as fever, sweats, chills, muscle pain, cough, shortness of breath, cough with bloody mucus, weight loss, skin sores, stomach pain, diarrhea, or painful urination.

Make sure you are current on all vaccines before you start using Cosentyx.

Tell your doctor if you are pregnant or breastfeeding.

How should I use Cosentyx?

Use Cosentyx 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.

Cosentyx is injected under the skin.

Ask your doctor or pharmacist if you don’t understand how to use an injection.

Prepare an injection only when you are ready to give it. You may need to use 2 injections to get your total dose.

Cosentyx should be clear or light-yellow. Call your pharmacist if the liquid Cosentyx in your vial, pen, or syringe looks cloudy, has changed colors, or has particles in it.

Your healthcare provider will show you where to inject Cosentyx. Do not inject into the same place two times in a row. Avoid injecting into skin that is hard, red, bruised, swollen, tender, or affected by  psoriasis . Do not inject within 2 inches of your navel (belly button).

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

Do not reuse a needle or syringe. Place them in a puncture-proof “sharps” container and dispose of it following state or local laws. Keep out of the reach of children and pets.

Store Cosentyx in the original container in a refrigerator. Protect from light and do not shake or freeze.

Take the injection pen out of the refrigerator and let it reach room temperature for 15 to 30 minutes before using. Give the injection within 1 hour after removing the medicine from a refrigerator.

You may store an injection pen or a prefilled syringe at room temperature (no higher than 86 degrees F) for up to 4 days. Return the pen or syringe to the refrigerator if not used within 4 days. Throw an injection pen or syringe away if left at room temperature for longer than 4 days.

Throw away a prefilled syringe or injection pen after one use, even if there is still medicine left inside.
