What side effects does Cosentyx (secukinumab) have, and which ones include rash?
Cosentyx can cause skin-related side effects, including rashes. In clinical use, people may report rash and other skin reactions as part of the drug’s overall safety profile. Reports can range from mild skin changes to more concerning reactions that need prompt medical attention.
When is a rash from Cosentyx likely to be urgent?
Seek urgent medical care if a rash comes with any signs of a serious drug reaction, such as:
- Trouble breathing or swallowing
- Swelling of the face, lips, tongue, or throat
- Blistering, peeling skin, or sores in the mouth
- Fever, severe illness, or rapidly worsening rash
These warning signs are important regardless of which medication caused the rash, because they can indicate a severe hypersensitivity reaction.
What other Cosentyx side effects do patients commonly ask about besides rash?
Along with skin reactions, Cosentyx’s side effects can include broader effects such as:
- Infections (because it affects the immune system)
- Upper respiratory symptoms (like runny nose or sore throat)
- Injection-site reactions
If you have rash plus symptoms of infection (fever, worsening cough, burning with urination), contact a clinician promptly.
Could Cosentyx trigger an allergic reaction?
Yes. Rash can be part of an allergic or hypersensitivity reaction. If the rash is accompanied by hives, facial swelling, or breathing difficulty, treat it as an emergency and get help right away.
What should you do if you develop a rash after starting Cosentyx?
- Do not ignore it, especially if it appears soon after starting or after dose changes.
- Contact your prescriber to discuss whether you should continue the medication and what treatment to use for the rash.
- If symptoms suggest a severe reaction (blistering/peeling skin, swelling, breathing trouble), go to the ER or call emergency services.
How do clinicians distinguish Cosentyx rash from psoriasis or eczema flares?
Sometimes skin changes may be mistaken for psoriasis activity. Clinicians typically look at:
- Timing relative to Cosentyx doses
- Rash appearance (hives vs flat patches, blisters vs non-blistering)
- Associated symptoms (itching, fever, swelling)
- Whether other psoriasis signs are changing at the same time

If you tell me a few details, I can help narrow “rash” risk
If you share:
1) how soon the rash started after a dose,
2) what it looks like (hives vs red patches vs blisters),
3) where it is on the body, and
4) whether you have fever, swelling, or breathing symptoms,
I can help you decide what level of urgency fits the situation.
