What kind of rash does Cosentyx (secukinumab) cause?
Cosentyx (secukinumab) can cause skin reactions in some people. Patients and prescribers commonly describe these reactions as rashes or rash-like eruptions after starting treatment, but the exact appearance can vary from person to person.
When does the rash show up after starting Cosentyx?
Rashes related to medications can occur soon after the first doses or after you’ve been on treatment for a while. Timing can vary depending on the type of reaction and each patient’s immune response.
When is a Cosentyx rash an emergency?
Seek urgent medical care right away if a rash comes with signs of a serious allergic reaction, including:
- trouble breathing or wheezing
- swelling of the face, lips, tongue, or throat
- widespread hives
- fever with a rapidly worsening rash
Could the rash be something else (infection, eczema flare, or another drug)?
A new rash during biologic therapy can also reflect causes other than the drug itself, including:
- viral or bacterial skin infections
- psoriasis/eczema flare
- reaction to another medication you started around the same time
Because causes can look similar, clinicians typically assess the rash pattern, distribution, timing, and any other symptoms.
What should you do if you get a rash on Cosentyx?
Don’t stop Cosentyx on your own. Contact the prescribing clinician promptly to describe:
- when the rash started (after how many doses)
- what it looks like (bumps, hives, peeling, blisters, redness)
- whether it itches, burns, or hurts
- whether you have fever, mouth sores, or swelling
The clinician may decide whether to continue treatment, pause it, or switch therapies based on severity.
Does Cosentyx have alternatives if rashes are a problem?
If secukinumab causes an intolerable rash, doctors may consider other biologics or targeted therapies for the underlying condition (psoriatic arthritis, ankylosing spondylitis, or plaque psoriasis), depending on what you’re treating and your medical history.
