What are Otezla and Cosentyx used for?
Otezla (apremilast) and Cosentyx (secukinumab) are both used to treat inflammatory conditions, but they target different parts of the immune pathway.
- Otezla is used for plaque psoriasis, psoriatic arthritis, and Crohn’s disease (immune-mediated inflammation).
- Cosentyx is used for plaque psoriasis, psoriatic arthritis, and ankylosing spondylitis, among other immune-mediated inflammatory diseases.
How do they work differently?
They differ mainly in mechanism:
- Otezla (apremilast) is an oral medicine that modulates immune signaling by inhibiting PDE4.
- Cosentyx (secukinumab) is a biologic (injection) that blocks IL-17A, a key cytokine involved in psoriatic inflammation.
Because of these different targets, they can vary in how quickly symptoms improve and in which patients respond best.
Oral pill vs injection: what does that mean for patients?
- Otezla is taken by mouth, which many patients prefer for convenience.
- Cosentyx is given by injection, typically using a prefilled pen or syringe, and is usually started with a loading schedule before moving to maintenance dosing.
How do they compare for psoriasis and psoriatic arthritis?
Both can treat plaque psoriasis and psoriatic arthritis, but clinicians choose between them based on factors like:
- severity and extent of disease,
- prior treatments and response,
- patient preferences (oral vs injectable),
- comorbid conditions and safety considerations.
In real-world practice, biologics like Cosentyx often deliver strong skin responses, while Otezla’s advantage is the oral route and a non-biologic approach.
What side effects do patients ask about?
Since the drugs work through different immune pathways, their side-effect profiles differ:
- Otezla commonly causes gastrointestinal side effects such as diarrhea and nausea, and can also be associated with weight loss in some patients.
- Cosentyx is associated with infection risk typical of immune-modulating biologics, and can cause issues like upper respiratory infections. Because it blocks IL-17A, fungal infections (especially Candida-related infections) can be a concern for some patients.
Your clinician’s selection often weighs your infection history, other medications, and your treatment goals.
Can someone switch between Otezla and Cosentyx?
Switching is possible, but the timing and strategy depend on:
- why the current therapy isn’t working (lack of response vs side effects),
- the patient’s current disease control,
- infection risk and other health conditions,
- how long it will take for the new therapy to reach effective levels.
Clinicians typically plan transitions to minimize flare risk while managing safety.
Cost and insurance: which tends to be more expensive?
Biologics like Cosentyx are usually more expensive than oral non-biologics like Otezla, and insurance coverage often determines out-of-pocket costs. Coverage varies widely by plan and by whether a patient has tried other therapies first.

Who should ask about one versus the other?
Consider discussing Otezla if you want a non-biologic, oral option and you’re weighing gastrointestinal effects and possible weight changes against the benefit.
Consider discussing Cosentyx if you’re interested in an IL-17A-targeting biologic option and you want to avoid PDE4-related GI effects, but can manage injection logistics and infection-related considerations.
If you tell me which condition you’re treating (plaque psoriasis vs psoriatic arthritis vs Crohn’s vs something else), your prior treatments, and whether you prefer oral or injection therapy, I can narrow the comparison to what matters most for that specific situation.
