Are there any over-the-counter (OTC) options similar to Cosentyx?

No. Cosentyx (secukinumab) is a prescription medicine and there are no true OTC substitutes that work the same way.

Cosentyx is a biologic antibody that targets interleukin-17A (IL-17A), a specific immune pathway involved in conditions like plaque psoriasis, psoriatic arthritis, and ankylosing spondylitis. OTC products are not able to replicate that targeted immune mechanism.

What OTC options can help symptoms (even if they aren’t similar to Cosentyx)?

OTC products can sometimes support symptom control for skin-related disease, especially for plaque psoriasis, but they don’t replace Cosentyx’s immune-targeting effect. Common OTC categories include:
- Moisturizers and emollients to reduce scaling and itch
- Anti-itch products (often containing ingredients like pramoxine or menthol)
- Topical keratolytics for scale (for example, salicylic acid)
- Medicated coal tar products in some countries/markets (less common, depends on local availability)

These may make lesions feel better or reduce visible scale, but they do not treat the underlying immune driver the way secukinumab does.

Can supplements replace Cosentyx?

OTC supplements (like omega-3s, curcumin, or vitamin D) are sometimes used by people with psoriasis or arthritis, but they are not equivalent to Cosentyx and are not considered a substitute for an IL-17A biologic. Evidence is mixed and they generally don’t provide the same degree of disease control.

When do people ask about OTC “alternatives,” and what’s the safest approach?

People usually look for OTC help when symptoms flare or they can’t access a prescription or biologic. The safest approach is to use OTC products as add-ons for comfort while discussing treatment options with a clinician—especially if your disease involves joints (psoriatic arthritis) or is moderate to severe, where symptom-only management can miss ongoing inflammation.

What about biosimilars or prescription alternatives instead?

If the goal is something similar to Cosentyx, the closest “alternatives” are other prescription biologics or biosimilars that target related immune pathways (and may include IL-17 blockers). Those options are prescription-based, not OTC.

If you tell me which condition you’re treating (plaque psoriasis, psoriatic arthritis, ankylosing spondylitis, etc.) and what country you’re in, I can narrow down what non-Cosentyx prescription options are commonly considered and what symptom-focused OTC options may help alongside them.
