Can Cosentyx (secukinumab) cause sinus infections?
Cosentyx is a biologic that blocks IL-17A, which can affect immune responses. Because of that, patients can be more prone to infections, including upper respiratory infections. If you’re seeing new or worsening sinus symptoms after starting Cosentyx, it’s important to treat the cause promptly and involve your clinician, especially if symptoms persist or worsen.
Should you stop Cosentyx if you get a sinus infection?
Do not stop Cosentyx on your own. Instead, contact the prescriber for guidance. Your clinician may:
- Continue treatment if the infection looks mild and you’re improving.
- Pause dosing temporarily if the infection is more serious, persistent, or not responding to treatment.
- Reassess the plan if you have recurrent infections.
The right approach depends on severity, whether it’s bacterial vs viral, and whether you have fever, severe facial pain, or other red flags.
What sinus infection symptoms mean you should get checked urgently?
Seek medical care promptly if you have signs that could indicate a more serious infection, such as:
- High fever
- Severe facial pain or swelling around the eyes
- Symptoms that are getting worse instead of better after a few days
- Severe headache, vision changes, or eye movement pain
- Thick drainage with significant worsening, especially if symptoms last more than 10 days
Viral vs bacterial sinusitis: does Cosentyx change how it’s treated?
Many sinus infections start viral and improve with supportive care. Bacterial sinusitis is more likely when symptoms last longer than about 10 days without improvement, are severe (high fever and significant facial pain), or worsen after initial improvement. Because Cosentyx can increase susceptibility to infections, clinicians may have a lower threshold to evaluate you if symptoms are persistent or severe.
What should patients do right now if they’re on Cosentyx and have sinus symptoms?
- Call your prescriber for advice about continuing or holding the next dose.
- Ask whether you should be evaluated for bacterial sinusitis or other causes.
- Use supportive measures (saline rinses, hydration, pain/fever control) as recommended by your clinician.
- Watch closely for worsening or urgent red-flag symptoms.
When to ask about recurrent sinus infections while on Cosentyx
If you’re getting repeated sinus infections, bring that up at your next visit. Your clinician may review:
- Whether Cosentyx is still the best match for your condition
- Whether infections are truly sinus-related vs allergies or nasal inflammation
- Potential need for ENT evaluation
- Whether preventive strategies (and in some cases medication changes) are appropriate
