Yes, sporadic use of Cosentyx (secukinumab) can still cause side effects. This is because the medication does not depend on building up in one's system to cause side effects [1]. Cosentyx is a human monoclonal antibody that selectively neutralizes interleukin-17A (IL-17A), which is a protein involved in inflammatory processes in the body [2].

The side effects of Cosentyx can be categorized into common and serious ones. Common side effects include diarrhea, upper respiratory tract infections, and cold symptoms [3]. Serious side effects, which are less common, include serious infections such as tuberculosis (TB) and invasive fungal infections, as well as hypersensitivity reactions [3].

It is important to note that the risk of side effects does not increase or decrease based on the frequency of Cosentyx use. Rather, the risk is associated with the medication itself and the individual's response to it [1]. Therefore, even if Cosentyx is used sporadically, the individual is still at risk of experiencing side effects.

In summary, sporadic use of Cosentyx can still cause side effects, and the risk of experiencing side effects is not dependent on the frequency of use. Common side effects include diarrhea, upper respiratory tract infections, and cold symptoms, while serious side effects include serious infections and hypersensitivity reactions.
