Cosentyx (secukinumab) is a biologic drug that is used to treat several inflammatory conditions, including psoriasis, psoriatic arthritis, and ankylosing spondylitis. The drug works by targeting a protein in the body that causes inflammation, and it is administered as an injection under the skin.

According to drugs.com, Cosentyx has a half-life of approximately 28 days, which means that it takes about four weeks for half of the drug to be eliminated from the body [1]. However, it is important to note that the drug may stay in the body for longer or shorter periods depending on various factors, such as the patient's metabolism and kidney function.

The official Cosentyx website provides additional information on the drug's elimination from the body. According to the website, it takes about five months for the drug to be eliminated from the body after the last dose [3]. This means that patients who stop taking the drug may still have it in their system for several months.

It is important for patients who are taking Cosentyx to follow their doctor's instructions carefully and to not stop taking the drug without consulting their healthcare provider. Patients who have concerns about the drug's elimination from their body should speak with their doctor to discuss their individual situation.
