Does Cosentyx (secukinumab) cause blood pressure changes?
Cosentyx (secukinumab) is not commonly associated with causing blood pressure variations. In the available safety information from its prescribing materials and drug safety references, the most frequently discussed cardiovascular-related issues are not typically framed as a direct “blood pressure variation” risk the way they are for some other medicines.
That said, any injectable biologic can still cause side effects that may indirectly affect blood pressure (for example, allergic reactions), so clinicians and patients generally watch for acute symptoms such as dizziness, fainting, swelling, or shortness of breath, which can accompany serious reactions rather than routine, ongoing blood pressure variability.
What side effects should make someone check their blood pressure?
Patients on Cosentyx should be alert to symptoms that can accompany reactions that affect circulation or fluid balance. Seek medical care urgently if symptoms suggest an acute reaction, such as:
- Severe rash, facial or throat swelling
- Trouble breathing or wheezing
- Feeling faint or lightheaded
Routine monitoring is most important for people who already have hypertension, cardiovascular disease, or are taking other medications that can affect blood pressure.
Can Cosentyx affect blood pressure indirectly?
Even if Cosentyx itself is not a well-established cause of blood pressure swings, blood pressure can change for many reasons during treatment, including:
- Changes in pain, inflammation, sleep, or activity level (which can improve or worsen cardiovascular risk)
- Concurrent medications (for example, NSAIDs, steroids, decongestants, or other biologics)
- Intercurrent illness (infection and inflammation can raise blood pressure in some people)
So if someone sees new blood pressure variability after starting Cosentyx, it’s often worth reviewing the full medication list and recent health changes with a clinician.
What should you do if your blood pressure seems to vary after starting Cosentyx?
- Record readings (home cuff logs) and note timing relative to injections and any symptoms.
- Contact your prescriber if readings rise significantly, become consistently elevated, or are accompanied by concerning symptoms.
- Do not stop Cosentyx on your own; discuss risks/benefits and alternatives with your clinician.
If you share the pattern you’re seeing (for example, typical readings before vs. after starting, and how soon after dosing the changes occur), I can help you think through the most likely causes and what to ask your doctor.

Because you asked specifically whether biologics like Cosentyx cause blood pressure variations, I’d normally cite Cosentyx’s safety labeling or a drug-safety database entry for secukinumab. However, no specific source content was provided in your prompt. If you want, tell me your country (US/EU/UK/etc.) and I can point you to the most relevant labeling and safety references for that region.
