Can Cosentyx cause a sore throat?
Yes. Secukinumab (Cosentyx) can be associated with upper respiratory symptoms, including sore throat, as part of infections such as pharyngitis or other respiratory illnesses [1]. Because Cosentyx suppresses immune signaling pathways used in inflammation, people taking it can be more susceptible to certain infections [2].
When should sore throat be treated as an infection vs. an allergy/serious reaction?
A sore throat can range from mild viral irritation to signs of an infection. Seek urgent care if you have any of the following along with sore throat:
- Trouble breathing, wheezing, swelling of the face/throat, or hives (possible allergic reaction) [1]
- Fever, rapidly worsening throat pain, or inability to swallow fluids (possible bacterial infection or more severe illness) [1][2]
What should you do if you get a sore throat while on Cosentyx?
Contact your prescriber for guidance, especially if symptoms are significant or last more than a day or two. Your clinician may recommend holding a dose and evaluating for infection, depending on severity and whether you have fever or other concerning symptoms [2]. If you recently started Cosentyx or recently increased dosing, it is especially important to get prompt advice.
Could Cosentyx increase risk of infections that cause sore throat?
Cosentyx targets IL-17A, which plays a role in defenses against certain infections. In clinical use, patients can develop infections including respiratory tract infections [2]. That is one reason sore throat can come up while taking it.
What other causes should be considered?
Sore throat in someone on Cosentyx can also be from common, non-drug-specific causes such as:
- Viral colds
- Post-nasal drip/allergies
- Acid reflux
- Strep throat or other bacterial pharyngitis
Your clinician can decide whether you need a throat exam or testing.
Is it safe to take Cosentyx if you currently have a sore throat?
Don’t guess. The safest approach is to ask your prescriber. Guidance depends on whether the sore throat is linked to infection and how severe it is [2]. Some people may be advised to delay a dose while they’re actively sick.
What information should you tell your doctor?
Be ready to share:
- When the sore throat started
- Whether you have fever, cough, runny nose, swollen neck glands, or white patches in the throat
- Any trouble swallowing or breathing
- Any new rash or swelling/allergy symptoms
- Your Cosentyx dosing schedule and last injection date [1][2]
