How long should you wait to inject Cosentyx after a flu shot?
You generally should be able to give the Cosentyx (secukinumab) injection the same day or without a long waiting period after an inactivated influenza (flu) vaccination, as long as you feel well. Cosentyx is used for autoimmune conditions and does not require a specific delay after a flu shot in routine practice.
What if the flu jab was a live vaccine?
A longer separation may be relevant only with live vaccines. Many standard seasonal flu vaccines used in routine care are inactivated, but some countries use live attenuated nasal flu vaccines. If your flu jab was a live vaccine, your clinician may recommend waiting longer before starting or continuing immunosuppressive biologics like Cosentyx.
What should you do if you feel unwell or had a reaction?
If you have fever, significant illness, or a strong reaction to the flu shot, clinicians often advise delaying the Cosentyx injection until you recover. Minor local symptoms (like arm soreness) usually do not require a delay.
What do you tell your pharmacist or prescriber?
Ask them to confirm which type of flu vaccine you received (inactivated injection vs live attenuated) and then confirm whether any timing adjustment is needed for your specific Cosentyx dosing schedule.
