What eye problems has Cosentyx (secukinumab) been linked to?
Cosentyx is an immune-targeting medicine (IL‑17A inhibitor) used for conditions such as psoriasis, psoriatic arthritis, and ankylosing spondylitis. Eye problems are a known concern with this drug class and with the underlying inflammatory conditions it treats. Reported eye-related side effects include inflammation of the eye.
The most commonly discussed serious eye issue is uveitis (inflammation inside the eye). This matters because uveitis can cause pain, light sensitivity, redness, and blurry vision, and it needs prompt evaluation.
Could Cosentyx worsen uveitis or trigger inflammation?
Yes. If you develop symptoms suggestive of uveitis or other inflammatory eye conditions after starting Cosentyx, clinicians typically treat that as a warning sign rather than “wait and see.” The key point is not only whether the drug can cause eye problems, but also that new eye inflammation while on treatment warrants urgent medical assessment.
What symptoms should make you stop and get urgent eye care?
Seek urgent care if you have new or worsening:
- Eye pain
- Redness
- Sensitivity to light
- Blurred or decreased vision
- Sudden floaters or other new vision changes
These symptoms can align with uveitis or other eye inflammation, which should be evaluated quickly to protect vision.
Are eye problems more likely if you already have inflammatory disease?
They can be. Conditions that Cosentyx treats—especially psoriatic disease and spondyloarthritis—are associated with a higher baseline risk of eye inflammation (including uveitis). So even if Cosentyx is causing or contributing, it can also be hard to separate “drug effect” from “disease-related risk.” Either way, new symptoms should be checked promptly.
How is the issue usually handled if eye inflammation happens?
Management typically involves:
- Contacting the prescriber promptly
- Eye specialist evaluation (often ophthalmology)
- Deciding whether to hold or discontinue Cosentyx depending on the diagnosis and severity, and starting the right eye treatment for the inflammation
Your clinician will weigh the eye risk against the need to control the underlying inflammatory condition.
When should you report eye symptoms, even if they seem mild?
Report them right away if they’re new after starting Cosentyx or worsening over days. Even mild redness or discomfort can be early signs of inflammation. Because eye inflammation can affect sight, timely assessment is safer than waiting.
