Can I take Cosentyx (secukinumab) if I have a cold?
Cosentyx is an immune-modifying medicine (it targets interleukin-17A). If you have an active infection such as a cold with worsening symptoms, most clinicians advise holding the dose and talking to the prescribing doctor first—because suppressing parts of the immune response can make infections harder to clear.
If your “cold” symptoms are mild and you’re otherwise well, some people may still be able to continue treatment, but that depends on how sick you feel and whether there are signs of a more serious infection (like fever or chest symptoms). The safest next step is to check with your doctor who manages your Cosentyx.
What symptoms mean you should pause and contact your clinician?
Contact your healthcare team before injecting if you have any of these:
- Fever, chills, or feeling significantly unwell
- Symptoms getting worse rather than better
- Shortness of breath, wheezing, chest pain, or worsening cough (possible lower respiratory infection)
- New or draining skin sores, worsening rash, or signs of cellulitis
- Any concern for an infection beyond a typical mild runny nose
What if it’s just runny nose or mild throat irritation?
With very mild, improving symptoms, some patients do inject while others hold and wait for recovery. Because Cosentyx changes immune responses, your individual risk matters (for example, other immune conditions, steroid use, or prior serious infections). Your prescriber can tell you whether to proceed or delay based on your situation.
Do I need to wait until symptoms fully go away?
Often clinicians recommend waiting until you are clearly improving and no longer have signs of infection. The exact timing varies, so follow your prescriber’s instructions rather than using a fixed number of days.
What should you do right now?
- If you have a fever or feel more than “mildly sick,” do not inject until you speak with your doctor.
- If symptoms are mild, still contact your prescriber/pharmacy for guidance before dosing.
- Seek urgent care if you develop breathing trouble, severe weakness, high fever, or worsening chest symptoms.

I don’t have prescribing-label or guideline text in the information provided to me here, so I can’t cite specific safety wording for “cold” from Cosentyx’s label. If you share your country or the Cosentyx package insert text you’re using, I can interpret the exact instructions more precisely.
