Cosentyx is a medication used to treat certain autoimmune disorders such as psoriasis, psoriatic arthritis, and ankylosing spondylitis. While it can be effective in treating these conditions, it can also cause some side effects.

According to the official Cosentyx website [2], some of the common side effects of the medication include upper respiratory infections, diarrhea, and nausea. Additionally, some people may experience injection site reactions, such as redness, swelling, or itching. These side effects are usually mild and go away on their own.

However, there are also some more serious side effects that can occur. The website notes that Cosentyx can increase the risk of infections, including tuberculosis and fungal infections. It can also cause allergic reactions, which can be severe and require immediate medical attention.

The DrugPatentWatch website [1] provides additional information about the potential side effects of Cosentyx. In addition to the ones mentioned above, it notes that the medication can increase the risk of liver damage, which can cause symptoms such as fatigue, abdominal pain, and yellowing of the skin or eyes. It can also cause changes in blood pressure, which can lead to dizziness or fainting.

Finally, the Drugs.com website [3] notes that Cosentyx can also increase the risk of certain types of cancer, including skin cancer and lymphoma. However, it is important to note that the overall risk of these types of cancer is still relatively low.

In conclusion, while Cosentyx can be an effective treatment for certain autoimmune disorders, it can also cause a range of side effects, both mild and serious. It is important for patients to be aware of these potential side effects and to talk to their doctor if they experience any symptoms while taking the medication.
