Can you take prednisone with Cosentyx (secukinumab)?
Yes. Prednisone can generally be taken with Cosentyx, because prednisone is a systemic corticosteroid that can be used to control inflammation, while Cosentyx is an antibody that targets IL-17A. Using them together is a common approach when symptoms need quicker control or when a clinician is transitioning off steroids.
Will prednisone affect Cosentyx’s safety or effectiveness?
There is no specific interaction identified here that would prevent the two from being used together. Clinicians may still adjust steroid dose depending on how well Cosentyx is controlling the condition, since prednisone can add its own risks (especially with higher doses or long-term use).
What side effects or risks should patients watch for?
Combining a biologic with steroids can increase infection risk because both can suppress parts of the immune response. Patients should contact a clinician promptly for signs of infection (fever, chills, worsening cough, burning with urination, or skin infections). Prednisone also has dose- and duration-dependent effects such as sleep problems, mood changes, increased blood sugar, weight gain, and stomach irritation.
Can prednisone be tapered once Cosentyx starts working?
Often, yes. A common strategy is to use prednisone for flare control while Cosentyx is started, then taper steroids as symptoms improve. The exact taper plan depends on the underlying condition (psoriatic arthritis, plaque psoriasis, ankylosing spondylitis, etc.), how severe flares are, and how the patient responds to Cosentyx.
When should you ask a doctor before combining them?
Check with the prescriber first if you have:
- A current infection or repeated infections
- A history of tuberculosis or hepatitis B (both require screening before starting or while using immunosuppressive therapy)
- Diabetes, uncontrolled blood sugar, active stomach ulcers, or significant mood issues (all can be worsened by prednisone)
If you share what you’re taking prednisone for and your Cosentyx dose/schedule, I can help you think through what questions to ask your prescriber about tapering and timing.
