Does Cosentyx cause weight gain?
Cosentyx (secukinumab) is not commonly associated with weight gain as a direct side effect in the information provided here. In practice, changes in body weight reported by patients are more often linked to underlying conditions (like psoriasis or psoriatic arthritis), changes in activity, or use of other medications.
Why do some people think Cosentyx caused weight gain?
When people start a biologic like Cosentyx, weight changes can happen for reasons that are not actually caused by the drug itself, such as:
- Improved inflammation: as symptoms improve, some people become more active, while others may notice appetite changes.
- Shifts in diet or routine: starting therapy can coincide with other lifestyle or treatment changes.
- Switching from other medications: prior drugs for inflammatory disease can affect weight indirectly.
What side effects should make you call your clinician?
Even if weight gain is not a typical “headline” effect, you should contact your prescriber if weight increases quickly or comes with concerning symptoms such as swelling, shortness of breath, or new fluid retention.
What you can track to figure out whether it’s the medication
If you’re trying to connect weight change with treatment timing, it helps to track:
- When the weight change started relative to your first Cosentyx dose (and dose changes)
- Whether the change is steady or sudden
- Any swelling, appetite changes, or fatigue
- Changes in other meds, steroids, or comorbid conditions
Are there other biologics for psoriasis/psoriatic arthritis that have different weight effects?
If weight gain is a major concern, it’s worth discussing alternatives within the psoriasis/psoriatic arthritis treatment options with your clinician. Your team can weigh the tradeoff between controlling symptoms and minimizing side effects.

If you tell me what condition you’re treating (plaque psoriasis vs psoriatic arthritis vs another) and roughly when the weight gain started after starting Cosentyx, I can help you think through the most likely explanations and what to ask your prescriber.
