Cosentyx is a medication that is used to treat a variety of autoimmune diseases, including psoriasis, psoriatic arthritis, and ankylosing spondylitis. While it is generally considered to be a safe and effective treatment option, there are some potential complications that users should be aware of.

According to Drug Patent Watch [1], some of the reported side effects of Cosentyx include infections, allergic reactions, and injection site reactions. In rare cases, users may also experience serious side effects such as tuberculosis, liver damage, and neurological disorders.

The official Cosentyx website [2] also lists several potential side effects of the medication, including infections, allergic reactions, and injection site reactions. Other possible side effects include diarrhea, nausea, and flu-like symptoms.

Medical News Today [3] reports that while Cosentyx is generally well-tolerated, there have been some reports of serious complications associated with the medication. These include an increased risk of infections, particularly in people who have a history of tuberculosis, and an increased risk of cancer, particularly skin cancer.

It is important to note that while these complications are possible, they are relatively rare. Most people who use Cosentyx do not experience any serious side effects. However, if you are considering using this medication, it is important to talk to your doctor about the potential risks and benefits, and to report any side effects or complications that you experience.
