Cosentyx is an immunosuppressant that works by blocking the effects of a protein in the body called interleukin 17A that can cause inflammation. It is a monoclonal antibody and belongs to the drug class called interleukin inhibitors. Blocking the protein's activity reduces inflammation, pain, swelling, and any skin symptoms that you may have.

Cosentyx is given as an intravenous infusion by a healthcare provider, or as a subcutaneous (under-the-skin) injection. It is typically given monthly after the first starting doses.

The most common side effects of Cosentyx are diarrhea and cold symptoms, such as stuffy nose, sneezing, and sore throat. It also may increase your risk for infections.
