Cosentyx is a medication used to treat various conditions, including psoriasis, psoriatic arthritis, and ankylosing spondylitis. The active ingredient in Cosentyx is secukinumab, which is a type of biologic drug that targets a specific protein in the body called interleukin-17A (IL-17A) [1].

According to the drug's official website, Cosentyx may cause side effects that affect different organs and systems in the body [3]. The most common side effects of Cosentyx include infections such as upper respiratory tract infections, diarrhea, and reactions at the injection site, such as redness, swelling, and itching. In rare cases, Cosentyx may cause serious side effects, including allergic reactions, tuberculosis, fungal infections, and other serious infections.

In addition to the side effects mentioned above, a recent study published in the Journal of Rheumatology reported that Cosentyx may increase the risk of developing inflammatory bowel disease (IBD) [2]. The study found that patients with psoriatic arthritis who were treated with Cosentyx had a higher incidence of IBD compared to those who were treated with other medications.

Overall, while Cosentyx is an effective medication for treating certain conditions, it may cause side effects that affect different organs and systems in the body. Patients who are considering taking Cosentyx should discuss the potential risks and benefits of the medication with their healthcare provider [3].
