Cosentyx (secukinumab) is a biologic medication used to treat various autoimmune diseases such as psoriasis, psoriatic arthritis, and ankylosing spondylitis. It works by blocking a protein called interleukin-17A (IL-17A) that is involved in the inflammatory process.

According to the official website of Cosentyx, the safety and efficacy of the drug have not been established in pediatric patients under 18 years of age [2]. Therefore, the use of Cosentyx in children is not recommended.

The medical news today article also states that the safety and efficacy of Cosentyx have not been established in children [3]. However, the article mentions that there are no known side effects of Cosentyx in children because the drug has not been studied in this population.

The Drug Patent Watch website provides information on the patent status of Cosentyx and does not provide any information on the drug's side effects in children [1].

In summary, the use of Cosentyx in children is not recommended, as the safety and efficacy of the drug have not been established in this population. There is no information on the side effects of Cosentyx in children because the drug has not been studied in this population. It is important to consult with a healthcare provider before taking any medication, especially in children.
