We've done great things in the past. Today, we're doing great things for the future.

Merck Sharp & Dohme and Schering-Plough merged in 2009 to create a new company known as Merck & Co., Inc., Kenilworth, NJ, USA in the USA and Canada and MSD in the rest of the world including the Saudi Arabia.Today, we are the second-largest pharmaceutical company in the world. We also are a global leader in consumer products and animal care.

Both MSD and Schering-Plough have a long and rich history of working to improve people's health and well-being. Through the years, our researchers have helped to find new ways to treat and prevent illness - from the discovery of vitamin B1, to the first measles vaccine, to cold remedies and antacids, to the first statins to treat high cholesterol. Our scientists also have helped develop many products to improve animal health, including vaccines and antibiotics.

While we are proud of our past, we are enthusiastic about the future of this new company and we are excited to help create a healthier, brighter future for people around the world.
