Does Cosentyx (secukinumab) change appetite?
Cosentyx (secukinumab) is not commonly described as a direct appetite-altering medicine. In available safety information, appetite changes are not typically highlighted as a frequent or hallmark side effect compared with more recognized issues such as infections or injection-site reactions.
What appetite-related side effects do people report?
Some medicines in the same general area can be associated with nonspecific symptoms (for example, feeling unwell, nausea, or changes in weight). For Cosentyx specifically, the most commonly discussed effects are generally not framed as appetite changes, but individual experiences can vary. If you notice reduced or increased appetite after starting Cosentyx, it can be worth tracking alongside other symptoms (nausea, stomach pain, fever, fatigue) because those may point to a related problem rather than an appetite-specific reaction.
Could changes in appetite be from something else happening alongside Cosentyx?
Many people starting Cosentyx do so for conditions like psoriasis, psoriatic arthritis, or ankylosing spondylitis—conditions that themselves can affect energy levels, sleep, stress, and overall appetite. If appetite changes show up during treatment, common possibilities include:
- The underlying inflammatory condition improving or changing activity
- Intercurrent infections or other illnesses (some biologics can increase infection risk)
- Other medications you’re taking at the same time (steroids, NSAIDs, antidepressants, etc.)
When should you contact a clinician about appetite changes?
Check with your prescriber soon if appetite loss comes with red flags such as:
- Fever, worsening fatigue, or signs of infection
- Persistent vomiting or severe abdominal pain
- Unintentional rapid weight loss
- Allergic symptoms (swelling, hives, trouble breathing)
What should you do if appetite changes after starting Cosentyx?
If the change is mild and short-lived, many people simply monitor it. If it persists or worsens, contact the prescribing clinician rather than stopping the drug on your own. They may review other medications, assess for infection, and decide whether any adjustments are needed.
