How long should you wait between Cosentyx (secukinumab) and a flu shot?
Cosentyx is an immunomodulating drug (a biologic that targets IL‑17A). For patients on biologics, the key practical rule for vaccination timing is to give an inactivated (seasonal) flu shot at any routine point in care, including during treatment, rather than delaying for long “washout” periods.
Does the timing change for live vs inactivated flu vaccines?
Yes. Seasonal flu shots used in most countries are inactivated (or otherwise non-live) vaccines, which are generally the ones recommended for people taking biologics like Cosentyx. Live vaccines are handled differently and may require extra precautions and clinician guidance.
What if you’re due for a flu shot but your next Cosentyx dose is close?
In practice, clinicians typically avoid creating a special delay just for vaccination and instead schedule the inactivated flu vaccine around routine visits. If you want the most accurate guidance for your dosing schedule and vaccine type, your prescriber or pharmacist can confirm the plan based on whether the specific flu product is inactivated and where you are in your Cosentyx dosing cycle.
Where can I confirm the official recommendation for my situation?
Because vaccine timing can depend on the specific flu vaccine formulation and your health history, the most reliable place to verify the exact spacing advice is your prescribing information and your clinician’s vaccination plan. If you share your dosing schedule (how often you take Cosentyx) and whether you’re getting a standard inactivated flu shot, I can help translate the general guidance into a workable timetable.
