What other drugs work for plaque psoriasis with allergy-like symptoms?
Cosentyx (secukinumab) is used for plaque psoriasis by targeting interleukin-17A (IL-17A). Other effective options for plaque psoriasis also include IL-17 pathway drugs and agents that target different immune pathways involved in psoriasis.
Which biologics target IL-17A or the IL-17 pathway (closest to Cosentyx)?
Several biologics treat plaque psoriasis by acting on the IL-17 pathway, similar to Cosentyx:
- IL-17A inhibitors:
- Taltz (ixekizumab)
- Cosentyx (secukinumab)
- IL-17 receptor blocker:
- Bimzelx (bimekizumab) targets IL-17A and IL-17F
What about TNF-alpha inhibitors (another major psoriasis option)?
Some people who do not respond well to IL-17 drugs use TNF-alpha inhibitors, which also suppress immune signals involved in psoriasis. Examples include:
- Humira (adalimumab)
- Enbrel (etanercept)
- Remicade (infliximab)
- Cimzia (certolizumab pegol)
- Simponi (golimumab)
What if the treatment targets IL-23 instead?
Other biologics aim upstream by blocking IL-23, which plays a key role in psoriasis inflammation. Examples include:
- Tremfya (guselkumab)
- Skyrizi (risankizumab)
- Ilumya (tildrakizumab)
How do the newer IL-17 vs IL-23 vs TNF options compare for patients?
Clinicians often choose among these based on prior treatments, disease severity, comorbidities, and patient factors (such as whether there’s also psoriatic arthritis). IL-17 blockers and IL-23 blockers are commonly used for plaque psoriasis; TNF inhibitors are another established class, especially when IL-17/IL-23 options aren’t suitable.
Are there “allergic psoriasis” medicines specifically for allergies?
Psoriasis is an immune-mediated condition, not a classic allergy. There is no single “antihistamine for allergic psoriasis” approach that replaces biologics for moderate-to-severe disease. However, doctors may recommend allergy medications (like antihistamines) for itch or coexisting allergic conditions, while psoriasis-specific treatment is still targeted to immune pathways.
What medicines are used when psoriasis is milder?
For milder plaque psoriasis, treatments often include topical therapies (for example, corticosteroids, vitamin D analogs, and other skin-directed options). Phototherapy and oral systemic drugs can be used as disease severity increases, but those are not the same category as Cosentyx.
Important safety note to check with a clinician
If you have frequent infections or a history of inflammatory bowel disease, discuss medication choice carefully, because some psoriasis biologics can affect infection risk and may have differing GI considerations. Your prescriber can help match the drug class to your health history.

No sources were provided with your question, so I can’t cite where each drug’s approval or mechanism comes from. If you want, share whether you mean plaque psoriasis only (vs. psoriatic arthritis too) and your age/health conditions, and I can narrow the most comparable Cosentyx alternatives.
