Does Cosentyx (secukinumab) increase infection risk?
Cosentyx can increase the chance of infections because it suppresses parts of the immune system. In people taking secukinumab, infections can occur more often than in those not taking the drug, and certain types of infections (especially those involving the respiratory tract) are commonly monitored.
What kinds of infections are most concerning?
Clinicians typically watch for common infections such as upper respiratory infections (like colds) and more serious infections that may require medical attention. Because Cosentyx affects immune signaling, patients are also advised to report symptoms early and not to ignore signs of infection.
Are you “more prone” if you already have infections or certain risk factors?
Risk is higher when patients already have factors that make infections more likely, such as:
- a history of recurrent infections
- older age
- diabetes or other chronic illnesses
- taking other immune-suppressing medicines
If any of these apply, doctors usually assess infection history before starting and may monitor more closely during treatment.
What should patients do if they feel sick while on Cosentyx?
Patients are generally advised to contact their clinician promptly if they develop signs of infection (fever, worsening cough, shortness of breath, burning with urination, or other concerning symptoms). Clinicians may pause treatment and evaluate whether an infection needs treatment first.
Is this different from other biologics for psoriasis/psoriatic arthritis?
Different biologics can have different infection profiles depending on their mechanism. Cosentyx targets IL-17A, so clinicians consider infections that are more relevant to patients on IL-17 blockade when making comparisons and monitoring plans.
When should you avoid or delay Cosentyx?
Cosentyx is usually delayed or handled carefully if a patient has an active serious infection, because suppressing immune responses can worsen an ongoing infection.
If you tell me what infection you mean (for example, sinus infections, pneumonia, skin infections) and whether you’re comparing to a specific other medication, I can help you interpret what “more prone” is most likely to refer to.
