Does body weight impact cosentyx's efficacy?

Yes. Body weight can affect how Cosentyx (secukinumab) works for some people.

- Why: Secukinumab is a monoclonal antibody. In larger individuals, the same fixed dose can lead to somewhat lower drug exposure compared with lighter individuals.
- What the data suggest: Across Cosentyx indications (plaque psoriasis, psoriatic arthritis, axial spondyloarthritis), higher doses tend to provide better and more durable responses, and heavier patients may benefit from the higher-dose regimens when appropriate.
- Practical implication: Clinicians may choose a higher-dose regimen (e.g., 300 mg) for patients with higher body weight or for those who don’t respond adequately to the lower dose. The exact dosing depends on your indication and your body's response.

If you’re concerned about weight and Cosentyx efficacy, talk with your doctor. They can review your specific condition, weight, and treatment history and adjust dosing or consider alternatives if needed.
