Is it safe to take Cosentyx (secukinumab) if I have influenza?
Cosentyx (secukinumab) suppresses parts of the immune system involved in inflammation. Because of that, having an active viral infection raises a safety question: some immune-modulating biologics are typically held during significant acute infections until the infection improves. Guidance is often individualized based on how sick you are and whether the infection is mild or severe.
With only the question provided, there isn’t enough detail to state a definite “safe” or “not safe” answer for every situation. The practical next step is to contact the clinician who prescribes Cosentyx promptly for instructions specific to influenza severity and your risk factors.
What should I do right now if I’m on Cosentyx and I got the flu?
Most clinicians will want to know:
- How high your fever is and how long it has lasted
- Whether you have shortness of breath, chest pain, dehydration, confusion, or worsening symptoms
- Your age and other conditions (for example, chronic lung disease, heart disease, diabetes, or immune system risks)
If symptoms are severe or you’re getting worse, seek urgent care or emergency evaluation. If symptoms are moderate, call your prescriber for advice about whether to delay your next Cosentyx dose until you’ve recovered.
What happens if I miss or delay a Cosentyx dose because of the flu?
Delaying a dose may be recommended during acute infection, but the tradeoff is that your underlying condition (for example, psoriasis, psoriatic arthritis, or ankylosing spondylitis) may start to flare as drug levels fall.
Your prescriber can usually help balance these risks by advising:
- Whether to skip the current dose
- When to restart after flu symptoms improve
- Whether you need a different plan temporarily for pain or inflammation
Could influenza complications be more likely on Cosentyx?
Influenza can be more dangerous in people with underlying health issues, and immune-modifying treatments can increase the risk of infections or make some infections harder to clear. That means clinicians often take influenza more seriously in patients on biologics, especially if you have lung disease, are older, or have other comorbidities.
The key safety point is monitoring for red flags and getting timely treatment for influenza.
Should I take antiviral treatment for influenza while on Cosentyx?
Antivirals (like oseltamivir) are sometimes used to reduce duration and complications of influenza, particularly in higher-risk patients or those with more severe symptoms. Whether you qualify depends on your age, symptom onset timing, and risk profile.
A clinician can decide this quickly, which matters because antivirals work best when started early. If you suspect influenza, contact a healthcare professional promptly for advice about antivirals and supportive care.
What symptoms mean I should get emergency care?
Go to urgent care or the emergency department if you have signs such as:
- Trouble breathing or shortness of breath
- Chest pain
- Blue/gray lips or face
- Severe dehydration (very little urination, dizziness, inability to keep fluids down)
- Confusion, severe weakness, or worsening despite treatment
- Fever that is very high or not improving, especially in higher-risk people
How to prevent infections when on Cosentyx
Discuss with your healthcare team:
- Getting a flu shot (timing and eligibility for you personally)
- Other vaccines you may need before the next season
- Practical infection-prevention steps during outbreaks

Quick question so I can give more targeted guidance
Are you currently having fever and how many days since symptoms started, and was it confirmed as influenza (tested) or suspected?
