Does Cosentyx (secukinumab) cause weight loss or weight gain?
Cosentyx is not known as a medicine that reliably causes either weight loss or weight gain in most people. In general, prescribing information and clinical experience for biologics like secukinumab focus on side effects such as infections, injection-site reactions, and other immune-related effects rather than consistent weight change.
What side effects are more commonly linked to changes in body weight?
If someone notices weight gain or weight loss while taking Cosentyx, it’s often related to other factors rather than the drug directly—such as:
- Changes in disease activity. Better control of psoriasis or psoriatic arthritis can change diet, activity level, and overall body weight.
- Steroid use. If patients start, stop, or taper corticosteroids for inflammation, weight changes can follow.
- Eating and activity changes due to symptoms improving or returning.
When should you contact a clinician about weight changes?
Talk with the prescriber if weight change is rapid or comes with symptoms that suggest a problem beyond typical fluctuation, such as:
- New or worsening swelling, shortness of breath, or severe fatigue
- Signs of infection (fever, persistent cough, painful urination)
- Unexplained loss of appetite or ongoing diarrhea

Quick bottom line
For most patients, Cosentyx is not described as a drug that consistently causes weight loss or weight gain. Weight changes, when they happen, are more often tied to underlying inflammatory disease control, other medications (especially steroids), or lifestyle changes.
