What dose of Cosentyx do you use in people with obesity?
Cosentyx (secukinumab) dosing is the same regardless of body weight. Obesity does not change the standard dosing schedule because Cosentyx is not dosed by weight; it is given as a fixed dose based on the drug label and the indication being treated.
Is Cosentyx weight-based dosing for any condition?
No. Cosentyx uses fixed dosing (typically by subcutaneous injection or intravenous infusion depending on the indication and treatment phase), not a body-weight–adjusted dose.
Does obesity change how well Cosentyx works?
People with higher body mass may, in general, have different rates of response for some biologic therapies, but Cosentyx prescribing does not require an obesity-based dose change. If response is inadequate, clinicians usually focus on disease control, adherence, and whether the treatment plan needs adjustment rather than increasing the dose just because of weight.
What should you do if the response is not enough?
If symptoms or biomarkers do not improve as expected, your clinician can assess factors like ongoing disease activity, other medications, and how long you’ve been on therapy. They may consider whether you need to stay on the current dosing schedule longer, confirm you are following the correct regimen, or switch therapies based on clinical judgment and guideline-based care.

No sources were provided with your question, and I don’t have enough information here to cite the Cosentyx label or a dosing reference. If you share the indication you mean (psoriatic arthritis, ankylosing spondylitis, non-radiographic axial spondyloarthritis, or plaque psoriasis) and whether you mean loading vs maintenance, I can answer with the exact labeled schedule.
