McNeil Consumer Healthcare was founded on March 16, 1879, by 23-year-old Robert McNeil. In 1904, one of McNeil's sons, Robert Lincoln McNeil, became part of the company, and together they created McNeil Laboratories in 1933. The company focused on direct marketing of prescription drugs to hospitals, pharmacists, and doctors. Development of acetaminophen began under the leadership of Robert L. McNeil, Jr. , who later served as the firm's chairman. In 1959, Johnson & Johnson acquired McNeil Laboratories and a year later the company was able to sell Tylenol for the first time ever, without a prescription. In 1977, two subsidiary companies were created: McNeil Medicals Products and McNeil Consumer Products Company (also known as McNeil Consumer Healthcare). The focus of McNeil medicals products is to market prescription drugs. In 1993 McNeil medicals products merged with the Ortho Pharmaceutical to form Ortho-McNeil Pharmaceutical. In 2001 McNeil Consumer Healthcare changed its name to McNeil Consumer & Specialty medicals products. However, it was later changed to "McNeil Consumer Healthcare". The company markets over-the-counter and prescription medicals products including complete lines of Tylenol and Motrin IB (ibuprofen) products for adults and children.
