Does Cosentyx (secukinumab) list depression as a side effect?
Cosentyx (secukinumab) is known primarily for side effects related to infection risk (because it changes immune signaling), injection-site reactions, and upper respiratory symptoms. Depression is not a commonly listed or hallmark side effect in the standard safety information for Cosentyx, and there is no provided evidence here that it is an expected or frequent adverse reaction.
That said, individual reports can happen with many medications, including biologics. If someone taking Cosentyx develops new or worsening mood symptoms, it should be treated as clinically important rather than assumed to be unrelated.
What could cause mood changes while on Cosentyx?
Mood symptoms like depression can arise for reasons that are separate from the medication, such as:
- The underlying condition itself (for example, psoriasis or psoriatic arthritis can be associated with depression).
- Stress, sleep problems, or pain related to disease activity.
- Other medications taken at the same time.
Even when a drug is not the most likely cause, a careful review is still warranted if symptoms start after beginning treatment or get worse after dose changes.
What should you do if depression symptoms start after starting Cosentyx?
If depression symptoms appear or worsen while using Cosentyx, the practical next steps are:
- Contact the prescribing clinician promptly to discuss timing and severity.
- Seek urgent help right away if there are thoughts of self-harm or severe worsening mood.
- Do not stop or change the dose on your own unless your clinician advises it.
Clinicians often assess whether symptoms are new, whether they correlate with medication start dates, and whether other contributors (disease activity, sleep, comorbidities, other drugs) are more likely.
Could Cosentyx worsen mental health in people with prior depression?
The information provided here does not specify whether people with a history of depression are at higher risk while taking Cosentyx. In real-world practice, any person with prior depression should be monitored closely when starting or changing systemic treatments, and reported symptoms should be evaluated promptly.
Are there alternatives if mood symptoms are a concern?
If depression symptoms are temporally linked to Cosentyx and your clinician agrees a reassessment is needed, alternatives for psoriasis or psoriatic arthritis treatment may be considered (choice depends on diagnosis, disease severity, and prior therapies). A switch is typically weighed against infection risk and disease control, not based on mood symptoms alone.
If you want, tell me what condition you’re taking Cosentyx for (psoriasis, psoriatic arthritis, ankylosing spondylitis, etc.), when the mood symptoms started relative to your first dose, and whether you’re on any other medications—and I can help you think through what to discuss with your prescriber.
