Can you get a flu shot while taking Cosentyx (secukinumab)?
Cosentyx is an immune-modulating biologic that can lower part of your immune response. The key practical point is that many people taking biologics can still receive a flu shot, but the type of vaccine matters and you should confirm with your prescriber.
In general, people on immune-suppressing therapies are advised to avoid live vaccines and use inactivated vaccines instead. A standard seasonal flu shot is typically an inactivated vaccine, while the nasal spray flu vaccine is live.
What type of flu vaccine should you choose?
Ask your clinician or pharmacist specifically for:
- The regular injection “flu shot” (most commonly inactivated)
- Avoid the nasal spray flu vaccine (live)
Your prescriber may also time the shot based on your dosing schedule, but the most important rule is vaccine type (inactivated vs live) rather than timing alone.
When should you take it relative to your Cosentyx dose?
If you and your prescriber agree you should get the shot, many clinicians try to coordinate it with treatment timing to reduce the chance of side effects and to maximize immune response. Your exact schedule depends on how often you take Cosentyx and how stable your condition is, so the best timing guidance is individualized.
What if you’re sick right now?
If you currently have a fever or are actively ill, your clinician may recommend waiting until you’re better before getting vaccinated. This is a common precaution with immunomodulating medicines.
What side effects might happen?
After an inactivated flu shot, typical reactions include soreness at the injection site, mild fever, fatigue, or muscle aches for a day or two. With immune-modifying treatments, you still can get flu despite vaccination, but vaccination helps reduce risk and severity. Seek medical care urgently if you have signs of a serious allergic reaction (trouble breathing, swelling of face/lips, widespread hives).
Should you wait if your condition flares?
If your psoriasis, psoriatic arthritis, or ankylosing spondylitis is flaring, your prescriber may still recommend vaccination, but they may want to review your current status and any infection history first.
What to do next
Before you schedule the shot, contact the clinician who manages your Cosentyx and ask:
1) “Is the standard flu shot (injection) appropriate for me?”
2) “Should I avoid the nasal spray flu vaccine?”
3) “What timing works best with my Cosentyx dosing schedule?”
If you tell me your dosing frequency (every 4 weeks or every 2/1 weeks during loading, etc.) and whether you’re asking about the injection or nasal spray, I can help you frame the exact questions to ask your doctor.
