Can cosentyx cause nausea?

Can Cosentyx (secukinumab) cause nausea?

Yes. Nausea is a possible side effect reported with Cosentyx (secukinumab), though it is not among the most common effects. Patients may experience gastrointestinal symptoms such as nausea as part of treatment.

What other side effects are related to the stomach or digestion?

People taking Cosentyx may also report other stomach- or digestion-related symptoms, including abdominal discomfort. If nausea is accompanied by severe vomiting, inability to keep fluids down, or signs of an allergic reaction, it warrants prompt medical attention.

When should you call a doctor about nausea on Cosentyx?

Contact your clinician urgently if you have:
- Severe or persistent nausea that doesn’t improve
- Vomiting that prevents hydration
- Signs of an allergic reaction (such as hives, swelling of the face/lips, trouble breathing)
- Fever or worsening illness (especially because biologic medicines like Cosentyx can affect immune response)

Are there ways to manage nausea from Cosentyx?

If nausea occurs after dosing, some people find it helps to:
- Take injections at a time of day when you can rest if symptoms occur
- Eat a small meal beforehand (if your clinician agrees)
- Discuss anti-nausea options with your prescriber if it becomes bothersome

If you tell me how long you’ve been on Cosentyx and when the nausea happens relative to your injection, I can help you think through whether it fits a common pattern and what questions to ask your prescriber.
