Cosentyx is a medication used to treat certain autoimmune diseases, including psoriasis and psoriatic arthritis. While it is generally well-tolerated, there are potential side effects to be aware of.

According to the official Cosentyx website [2], some of the most common side effects of the medication include infections (such as the common cold or flu), diarrhea, and upper respiratory tract infections. These side effects are generally mild to moderate in severity.

However, there are also some more serious potential side effects to be aware of. Cosentyx can increase the risk of infections, including serious infections such as tuberculosis. It can also increase the risk of certain cancers, such as lymphoma. Patients should be monitored closely for signs of infection or cancer while taking Cosentyx.

Other potential side effects of Cosentyx include allergic reactions, liver problems, and inflammatory bowel disease. Patients should report any new or worsening symptoms to their doctor right away.

It is important to note that not all patients will experience side effects while taking Cosentyx. However, patients should be aware of the potential risks and discuss any concerns with their doctor.
