Cosentyx is a medication that is used to treat certain autoimmune diseases such as psoriasis and psoriatic arthritis. It is a biologic drug that works by blocking certain proteins in the body that cause inflammation. While it is an effective treatment, it is important to be aware of any potential side effects, particularly in children.

According to the Cosentyx website [2], the safety and effectiveness of Cosentyx in children under 18 years of age has not been established. Therefore, it is not recommended for use in this population. However, if a doctor does prescribe Cosentyx for a child, it is important to monitor them closely for any adverse effects.

The Drug Patent Watch website [1] lists some of the potential side effects of Cosentyx in adults, which could potentially also occur in children. These include infections, allergic reactions, and changes in liver function. Additionally, the website notes that there have been reports of depression and suicidal thoughts in patients taking Cosentyx, although it is unclear whether the medication was the cause.

A study published in the National Library of Medicine [3] looked at the safety and efficacy of Cosentyx in pediatric patients with psoriasis. The study found that the medication was generally well-tolerated, with the most common side effects being upper respiratory tract infections and injection site reactions. However, the study only included a small number of patients, and more research is needed to fully understand the potential risks and benefits of Cosentyx in children.

In conclusion, while there is limited information on the use of Cosentyx in children, it is generally not recommended for this population. If a doctor does prescribe it, they should monitor the child closely for any adverse effects. The potential side effects of Cosentyx in adults include infections, allergic reactions, changes in liver function, depression, and suicidal thoughts [1]. A small study found that Cosentyx was generally well-tolerated in pediatric patients with psoriasis, but more research is needed [3].
