Can you take prednisone and Cosentyx (secukinumab) together?
Cosentyx (secukinumab) and prednisone are often used together in real-world treatment plans for inflammatory conditions, because prednisone can rapidly reduce inflammation while Cosentyx works more gradually. There is no general, absolute “no” on combining a short course of prednisone with Cosentyx; the combination is commonly used under clinician guidance for disease flares or bridging.
Do prednisone and Cosentyx increase infection risk?
Yes. Prednisone and Cosentyx both affect the immune system, so using them together can increase the risk of infections. The risk depends on the prednisone dose, how long you take it, and your overall health (for example, diabetes, chronic lung disease, or prior serious infections). If you develop fever, worsening cough, painful urination, or other infection symptoms, contact your prescriber promptly.
What conditions is this combination typically used for?
Cosentyx is used for conditions such as:
- Plaque psoriasis
- Psoriatic arthritis
- Ankylosing spondylitis
- Non-radiographic axial spondyloarthritis
Prednisone is sometimes used as a short-term “bridge” or for flares while longer-acting therapies like Cosentyx take effect. Your clinician may adjust timing based on your flare pattern and prior response.
How should you time prednisone with Cosentyx?
There is no single universal timing rule for everyone. In many cases, prednisone is started temporarily and then tapered off while Cosentyx continues on its regular schedule. The key is that your prescriber coordinates the start, dose, and taper plan so you’re not on higher-dose prednisone longer than needed.
What should you tell your doctor before combining them?
Before using both, make sure your clinician knows:
- Any history of frequent or serious infections
- Tuberculosis (TB) history or exposure
- Hepatitis history
- Current vaccines (especially whether you’ve had recent live vaccines)
- Any other immune-suppressing medicines you take
What’s a common safety “watch-out” with Cosentyx specifically?
Cosentyx can increase susceptibility to infections, including certain bacterial and fungal infections. If you have a history of recurrent infections or you develop symptoms while on treatment, your prescriber may pause or reassess therapy.
When to get urgent medical advice
Seek urgent care if you have signs of serious infection, such as high fever, shortness of breath, severe weakness, confusion, or signs of a severe skin infection.
If you share which condition you’re treating (psoriasis, psoriatic arthritis, ankylosing spondylitis, etc.), your prednisone dose (e.g., 10 mg vs 60 mg) and whether it’s short-term or long-term, I can give more specific guidance on what questions to ask your prescriber.
