Our ultimate goal is to help people live healthy lives. We have produced and marketed many first-in-class prescription medications and are poised to serve the broad needs of the healthcare market – from patients to practitioners, from clinics to hospitals.

Headquartered in Titusville, New Jersey, Janssen is named after Dr. Paul Janssen, a leading Belgian researcher, pharmacologist, and general practitioner. Dr. Janssen led a group of researchers to discover a medicine that helped change the way mental health patients were treated. His company, Janssen Pharmaceutica, joined the Johnson & Johnson family of companies in 1961. Our company remains guided by Dr. Janssen’s values of excellence and innovation.
