How long should you wait between Cosentyx (secukinumab) and a flu shot?
For people taking Cosentyx (secukinumab), the general recommendation is to separate timing so the vaccine isn’t given during an immediate period of active treatment effect. Clinicians commonly advise getting the flu shot at a point in your dosing cycle—typically about midway or at least around 1–2 weeks before the next injection—rather than right next to a dose.
Because exact timing guidance can vary by country guidance, your dosing schedule (how often you take Cosentyx), and what type of flu vaccine you’re getting (standard inactivated flu shot vs. any live formulation), you should confirm the schedule with your prescribing clinician or pharmacist.
Can you get a flu shot while on Cosentyx?
Patients on Cosentyx are usually able to receive a standard inactivated flu vaccine. The key issue is coordinating timing with your medication schedule and using the correct flu vaccine type. Your pharmacist can confirm which influenza vaccine you’re receiving and whether it matches recommendations for people on biologics like Cosentyx.
What if you missed the timing window?
If you and your clinician didn’t time it perfectly, you usually don’t need to “restart” anything. Instead, you typically schedule the flu shot as soon as it’s practical, then continue Cosentyx on your usual dosing plan unless your clinician gives a specific adjustment.
What flu shot type matters (and how does that change the gap)?
The type of flu vaccine matters. Standard flu shots used for most adults are inactivated (non-live). Live attenuated influenza vaccines are handled differently and may not be appropriate for patients on certain immune-modulating therapies. If you tell me which flu shot you’re getting (the product name or whether it’s a standard shot in the arm vs. nasal spray), I can tailor the timing discussion more closely.
What should you tell your doctor?
Bring these details so they can give a precise recommendation for your situation:
- Your Cosentyx dosing schedule (every 2 weeks vs. every 4 weeks, and your next injection date)
- Whether you’re receiving a standard injected flu shot or a nasal spray
- Any history of immune problems, recent infections, or current steroid use
If you share your Cosentyx dosing interval and your next injection date, I can help you identify a practical “time gap” window to ask your pharmacist/doctor about.
