Can Cosentyx (secukinumab) cause hives?
Yes. Hives (urticaria) are listed as a possible side effect of Cosentyx (secukinumab). Because hives can also be a sign of a more serious allergic reaction, it matters whether symptoms are mild and limited or come with other warning signs.
If you develop hives after starting Cosentyx, stop taking the next dose and contact the prescriber promptly for guidance.
What to do if you get hives after a Cosentyx dose
Seek urgent care or emergency help right away if hives are accompanied by any signs of a severe allergic reaction, such as:
- trouble breathing, wheezing, or tightness in the chest
- swelling of the face, lips, tongue, or throat
- dizziness, fainting, or feeling very unwell
For mild hives without other symptoms, you still should contact your clinician promptly. They may advise temporary treatment of symptoms (for example, an antihistamine) and decide whether Cosentyx should be continued or changed.
Are hives a common side effect of Cosentyx?
Hives are not the most common side effect, but they are recognized as a potential reaction. The key clinical point is that allergic-type skin reactions can occur, so new hives after dosing should be taken seriously.
Could this be something else instead of an allergy to Cosentyx?
Yes. Hives can be triggered by many factors, including infections, other medications, and other immune-related conditions. Timing matters: if the hives appear soon after Cosentyx and recur around dosing, drug-related allergy becomes more likely.
What should you tell your doctor?
Tell your doctor:
- when the hives started and when they occur relative to Cosentyx doses
- whether you had any breathing symptoms, facial swelling, or dizziness
- what other medicines you’re taking (including OTC drugs and supplements)
- whether you’ve had allergy reactions to biologics or other injections before
If Cosentyx is stopped, what alternatives exist?
If hives reflect an allergic reaction, clinicians may switch to a different psoriasis/psoriatic arthritis/ankylosing spondylitis therapy. The best alternative depends on your diagnosis and health history, and it’s typically decided by a rheumatologist or dermatologist.
