Are there similar side effects between cosentyx and the flu shot?

Research suggests that the side effects attributed to Cosentyx (secukinumab) and the flu shot may sometimes overlap, but it's essential to consider the context and the underlying conditions being treated.

Cosentyx, a biologic medication approved to treat psoriasis, psoriatic arthritis, ankylosing spondylitis, and certain other autoimmune conditions, has been associated with flu-like side effects, such as headache, fatigue, and dizziness, although these side effects are generally mild and temporary [1].

Similarly, flu shots, or influenza vaccines, are typically well-tolerated and may cause mild side effects, like headache, muscle pain, and fatigue, among others [2]. While flu-like side effects from Cosentyx and flu shots share some similarities, they may also exhibit unique characteristics and frequency profiles.

For instance, Cosentyx users may sometimes experience flu-like symptoms more intensely or longer than after a flu shot, with some research indicating that these reactions may be related to the body's immune response to the medication [3].

According to the Centers for Disease Control and Prevention (CDC) and the Centers for Biologics Evaluation and Research (CBER), both Cosentyx and flu vaccines are generally considered safe for use by adults [4].

More recent studies indicate flu vaccines are now available that are designed to not cause the flu like symptom after a flu vaccination [5][6] It is recommended that patients speak with their healthcare professional about the risks and benefits associated with their medication or vaccination.
