erenumab (injectable)

Erenumab is a medication used to prevent migraines. It belongs to a class of drugs called monoclonal antibodies, which are proteins designed to target specific substances in the body. Erenumab works by blocking a protein involved in the development of migraines, helping to reduce their frequency. It is used as a preventive treatment for adults who experience frequent migraines.
