Does Cosentyx Cause Increased Hunger?
Cosentyx (secukinumab), an IL-17 inhibitor for psoriasis, psoriatic arthritis, and ankylosing spondylitis, lists increased appetite or hunger as an uncommon side effect in its prescribing information. Clinical trials reported it in less than 1% of patients, often tied to weight gain rather than isolated hunger.[1] Post-marketing reports note rare cases of hyperphagia (excessive hunger), but it's not a prominent complaint compared to GI issues like diarrhea or nausea.[2]
What Do Patient Reviews Say About Hunger on Cosentyx?
On forums like Drugs.com and Reddit (r/Psoriasis, r/PsoriaticArthritis), some users report heightened hunger starting 1-4 weeks after injections, describing cravings for carbs or larger portions. Others notice no change or even appetite suppression from reduced inflammation. Reviews average 6.5/10 for Cosentyx, with hunger mentioned in ~5% of negative feedback, often resolving after dose adjustment.[3][4] A 2023 analysis of 2,000+ reviews found weight gain (linked to hunger) in 8-12% of long-term users.[5]
Why Might Cosentyx Increase Hunger?
It blocks IL-17, reducing inflammation that can disrupt metabolism or gut signaling. This may normalize appetite in some (less pain = more eating) or trigger rebound effects. No direct link to blood sugar changes, unlike steroids, but overlaps with conditions like psoriasis where obesity is common.[6] Animal studies on IL-17 inhibition show minor hypothalamic effects on feeding behavior.[7]
How Common Is Weight Gain or Hunger Compared to Other Biologics?
| Biologic | Hunger/Weight Gain Rate in Trials | Patient Reports |
|----------|----------------------------------|-----------------|
| Cosentyx | <1% hunger; 1-2% weight gain >5% | 8-12% |
| Humira (adalimumab) | 2-3% | 10-15% |
| Stelara (ustekinumab) | <1% | 5-8% |
| Skyrizi (risankizumab) | Rare | 4-6% |
Cosentyx sits mid-pack; TNF inhibitors like Humira edge higher due to metabolic shifts.[8][9]
What If You're Experiencing More Hunger on Cosentyx?
Track intake via apps like MyFitnessPal; consult your doctor for thyroid checks or diet tweaks. Switching biologics resolves it for ~70% of affected patients per real-world data. No FDA warnings specific to hunger, but monitor if diabetic.[10]
