Cosentyx (secukinumab) is a prescription medication used to treat various autoimmune conditions such as psoriasis, psoriatic arthritis, and ankylosing spondylitis. The drug works by targeting a protein in the body called interleukin-17A, which plays a role in inflammation. While Cosentyx has been effective in treating these conditions, there are some potential side effects and risks associated with its use.

According to the Cosentyx website [2], the most common side effects of the drug include diarrhea, upper respiratory tract infections, and injection site reactions. These side effects are generally mild to moderate in severity and tend to go away on their own. However, in rare cases, more serious side effects can occur. These may include allergic reactions, infections, and inflammatory bowel disease. Patients who experience any of these symptoms should contact their healthcare provider immediately.

In addition to these potential side effects, there are also some risks associated with the use of Cosentyx. For example, the drug may increase the risk of developing infections, particularly tuberculosis. Patients should be screened for tuberculosis before starting treatment with Cosentyx and should be monitored for signs of infection while taking the drug [2]. Additionally, Cosentyx may increase the risk of certain cancers, such as lymphoma. Patients should discuss the risks and benefits of treatment with their healthcare provider before starting Cosentyx [3].

Overall, while Cosentyx has been shown to be an effective treatment for autoimmune conditions, there are some potential side effects and risks associated with its use. Patients should be aware of these risks and should discuss any concerns with their healthcare provider before starting treatment.
