Could Cosentyx (secukinumab) cause a stuffed nose or sinus symptoms?
Cosentyx can cause upper-respiratory side effects in some people, including nasal congestion or sinus-related symptoms. If your “stuffed nose” started after beginning Cosentyx, it may be related.
What should I watch for to tell a medication side effect from an infection?
Sinus congestion can come from either medication effects or an infection. Pay attention to these red flags that suggest infection rather than a simple side effect:
- Fever, worsening facial pain/pressure, or symptoms that rapidly get worse
- Thick yellow/green nasal discharge with strong odor plus fever
- Shortness of breath, wheezing, or chest symptoms
- No improvement or worsening after about 7–10 days
Cosentyx (like other drugs that affect immune signaling) can increase susceptibility to some infections, so it’s important to get medical advice if symptoms look more than mild.
What can you do now to relieve congestion while staying on treatment?
Common steps people try (and that are generally reasonable) include:
- Saline nasal rinses or saline spray
- Staying well hydrated
- Using a humidifier and avoiding known irritants (smoke, strong fragrances)
- Checking whether any other new meds (cold meds, antihistamines, nasal sprays) were started around the same time
Do not stop Cosentyx on your own without speaking to your prescriber—especially if you’re using it for psoriasis, psoriatic arthritis, or ankylosing spondylitis, because flares can happen.
When should you contact your prescriber urgently?
Contact your clinician promptly or seek urgent care if you have:
- Trouble breathing or swelling of lips/face
- Severe sinus pain with fever
- Symptoms of an allergic reaction (hives, widespread rash, facial swelling)
- Persistent or worsening congestion despite home care
What else could cause a “stuffed nose” while on Cosentyx?
Other common causes include:
- Allergic rhinitis or seasonal allergies
- A viral cold
- Sinusitis
- Medication timing coincidence (cold/allergies starting around the same time)
If you tell your clinician whether you have allergies, a history of sinus infections, or recent exposures, it helps narrow down the cause.
Helpful details to share with your doctor
If you want, reply with:
1) Your dose (loading or maintenance) and when you started Cosentyx
2) How long the congestion has been happening
3) Any fever, facial pain/pressure, sore throat, cough, or thick discharge
4) Whether it feels like allergies (itchy eyes/sneezing) or infection (fever/worsening pain)
That lets a clinician decide whether this sounds like a typical upper-respiratory side effect, sinusitis that needs treatment, or something else.
If you share those details, I can help you phrase what to tell your prescriber and what questions to ask about whether to adjust treatment or treat the congestion.
