Can Cosentyx (secukinumab) cause nausea?
Nausea is a possible side effect reported with Cosentyx (secukinumab). In practice, many patients report it as mild and temporary, but any persistent or severe nausea should be discussed with a clinician, especially if it affects hydration or eating.
What other side effects might show up with nausea?
When people look up “Cosentyx nausea,” they are often also checking for other adverse effects that can accompany it, such as:
- Upper respiratory or flu-like symptoms
- Headache
- Diarrhea or stomach discomfort
- Injection-site reactions
If you have fever, worsening weakness, or signs of an infection, treat that as urgent rather than focusing only on nausea.
When should you stop and seek urgent care?
Seek urgent medical attention if nausea comes with any of the following:
- Severe vomiting or inability to keep fluids down
- Severe abdominal pain
- Signs of an allergic reaction (trouble breathing, swelling of face/lips, hives)
- High fever or other signs of infection
How can patients reduce nausea after starting Cosentyx?
Practical steps many patients use (and that clinicians commonly advise) include:
- Taking note of whether nausea is worse after injection doses.
- Eating small, bland meals around the time of dosing if that helps.
- Staying well-hydrated.
- Reviewing other medicines you take that could also cause nausea (for example, antibiotics or NSAIDs).
Because Cosentyx dosing schedules are specific, don’t change or skip doses without medical guidance.
Could Cosentyx nausea be mistaken for something else?
Yes. Nausea after starting a biologic can overlap with unrelated causes such as stomach viruses, new diet changes, reflux, medication interactions, or other conditions. If nausea starts soon after injections every cycle and improves when you’re past the dose window, that pattern can make Cosentyx-related effects more likely.
What about drug interactions?
Cosentyx has drug interaction considerations like other biologics, but the best guidance depends on your exact medication list and health conditions. If you share the other meds (prescription, OTC, and supplements), I can help flag common nausea-causing culprits to discuss with your clinician.

What should you do next?
If you tell me:
1) your dose (150 mg or 300 mg, and whether it’s weekly or every 4 weeks),
2) when the nausea starts after injection, and
3) whether you’re vomiting,
I can help you triage whether it sounds like a typical mild side effect versus something that needs prompt medical attention.
