Cosentyx (secukinumab) is a biologic medication used to treat certain autoimmune diseases such as psoriasis, psoriatic arthritis, and ankylosing spondylitis. It works by blocking a protein called interleukin-17A, which is involved in inflammation. While Cosentyx can be effective in managing these conditions, it is important to be aware of potential side effects, especially when taking the medication long term.

According to Drug Patent Watch [1], the most common side effects of Cosentyx are upper respiratory infections, diarrhea, and nasopharyngitis (inflammation of the nose and throat). Other potential side effects include allergic reactions, infections, and changes in blood pressure or liver function. It is also possible for Cosentyx to increase the risk of certain types of cancer, although this risk appears to be low.

Medical News Today [2] notes that while some side effects of Cosentyx may be mild and go away on their own, others may be more serious and require medical attention. For example, if a person experiences symptoms of an allergic reaction, such as difficulty breathing or swelling of the face or throat, they should seek immediate medical attention. Additionally, if a person experiences signs of an infection, such as fever or chills, they should contact their healthcare provider.

Healthline [3] also emphasizes the importance of monitoring for potential long-term side effects of Cosentyx. For example, the medication may increase the risk of infections, particularly if a person is taking other immunosuppressive medications at the same time. It is also possible for Cosentyx to affect a person's liver function, so regular blood tests may be necessary to monitor for this.

In conclusion, while Cosentyx can be an effective treatment for certain autoimmune diseases, it is important to be aware of potential side effects, especially when taking the medication long term. Common side effects include upper respiratory infections, diarrhea, and nasopharyngitis, while more serious side effects may include allergic reactions, infections, and changes in blood pressure or liver function. Regular monitoring and communication with a healthcare provider can help to minimize the risks associated with Cosentyx treatment.
