Can Cosentyx (secukinumab) cause skin irritation or new rashes?
Cosentyx (secukinumab) can be associated with skin-related side effects, including rashes or other skin irritation in some people. In clinical use, skin reactions are among the adverse effects patients sometimes report or clinicians monitor for.
What kinds of skin problems have people noticed with Cosentyx?
Skin issues reported with Cosentyx can include:
- Rash or hives
- Itching
- Redness or other irritation of the skin
These can look like mild irritation, but some reactions can be more significant, so any new or worsening rash should be taken seriously.
When should I stop and get urgent help?
Seek urgent care (or contact your prescriber right away) if you develop signs of a serious allergic or severe skin reaction, such as:
- Swelling of the face, lips, tongue, or throat
- Trouble breathing or wheezing
- Blistering/peeling skin, sores in the mouth, or widespread rapidly worsening rash
Could Cosentyx make skin infections more likely?
Because Cosentyx works by changing immune signaling, it may increase susceptibility to certain infections. If your “skin irritation” is actually an infection (for example, painful redness, warmth, spreading areas, pus, or fever), that needs medical evaluation rather than simply treating it as irritation.
What should I do if I get a rash while on Cosentyx?
- Contact your prescribing clinician to report the rash and describe how it looks and how fast it appeared.
- Do not stop the medication on your own unless you have emergency warning signs (swelling, breathing trouble, blistering/peeling, severe rapidly spreading rash).
- If you have a history of drug reactions, tell your clinician that up front.
What to tell your doctor to pinpoint the cause
Share:
- When the rash started relative to your last dose
- Where it is on your body and how it looks (itchy, raised, hives, flat, painful)
- Whether you have fever or symptoms of infection
- Any new creams, antibiotics, supplements, or other meds started around the same time
