Can I take Cosentyx (secukinumab) the same day as a flu shot?
In most cases, you can get a flu shot on the same day you take Cosentyx. Cosentyx targets interleukin-17A, and the flu vaccine is an inactivated (killed) vaccine for most people, which is generally compatible with immunosuppressive therapies.
What kind of flu shot matters (inactivated vs live)?
The main safety issue is whether the vaccine is live or inactivated. Most flu shots people receive are inactivated (shot form) and are typically considered safe with biologic immune-targeting medicines like Cosentyx. Live flu vaccines (given as a nasal spray) are a different category and are usually avoided during immunosuppressive treatment.
Should you separate timing, or is “same day” okay?
If your clinician recommends vaccination and you’re using the standard inactivated flu shot, same-day dosing is typically acceptable. Many clinicians don’t require spacing the injection and the vaccination because the flu shot itself isn’t live and isn’t expected to trigger the same concerns as a live vaccine.
What do you do if you’re due for Cosentyx the day of the shot?
You can usually proceed with both as planned. If you’re unsure which flu vaccine you’re getting (or whether you’ll be offered a live nasal version), ask the vaccination site or your prescribing clinician to confirm it’s the inactivated shot.
When to check with your doctor first
Ask your doctor or pharmacist before getting vaccinated on the same day if any of these apply:
- You were offered a nasal (live) flu vaccine instead of a standard shot.
- You’ve had a prior serious reaction to a flu vaccine.
- You’re being treated for an active infection or you’re not feeling well at the time of vaccination.
- You’re on other immunosuppressing medicines as well.

I can’t provide a definitive, patient-specific medical instruction from the information available here. For exact guidance tied to your situation, check with your prescriber or pharmacist. If you want, tell me whether you’re taking the regular flu shot (injection) or a nasal spray, and your Cosentyx schedule (weekly vs every 4 weeks), and I’ll tailor the general guidance to that scenario.
