What side effects does Cosentyx (secukinumab) cause?
Cosentyx can cause side effects that affect the skin, the digestive system, and the immune system. In patients treated with secukinumab, the most commonly reported effects include:
- Upper respiratory infections (such as runny nose, sore throat, or flu-like symptoms)
- Headache
- Diarrhea
- Injection-site reactions (redness, pain, or swelling where the shot is given)
Because Cosentyx changes immune activity, it can also increase the risk of certain infections.
What serious side effects should patients watch for?
Cosentyx carries risks related to infection and immune response. Serious side effects that patients should seek medical care for include:
- Signs of infection that don’t improve or get worse (fever, chills, feeling very unwell)
- Worsening or persistent infections
- Allergic reactions (such as swelling of the face or throat, trouble breathing, or widespread rash)
Cosentyx is associated with infection risk because it targets interleukin-17A, a pathway involved in immune defense.
Does Cosentyx increase the risk of infections (including fungal)?
Yes. By lowering signaling through interleukin-17A, Cosentyx can raise the risk of infections. One specific concern is fungal infections (patients should report symptoms such as persistent oral thrush or other unusual fungal symptoms).
What side effects are common after injections?
Injection-site reactions are a frequent local effect, typically mild to moderate. Patients may notice:
- Redness
- Pain or tenderness
- Swelling at the injection site
These reactions usually improve on their own, but worsening redness, severe pain, or signs of infection at the site should be evaluated.
Who is more likely to have side effects, and what increases risk?
Risk can be higher for people with:
- A history of recurrent infections
- Ongoing or recent infection at the time of starting therapy
- Significant immune suppression from other conditions or medications
Patients should tell their clinician about any infections they’ve had recently, and about any chronic conditions that affect immunity.
What to do if you get side effects while taking Cosentyx
Patients should:
- Contact a clinician if symptoms suggest infection or an allergic reaction
- Seek urgent care for breathing problems, facial/throat swelling, or rapidly worsening symptoms
- Discuss persistent diarrhea or severe headaches with a healthcare professional
