MSD first established its presence in Malaysia in 1965.  It started off by distributing products throughout Malaysia, with a staff strength of five employees. In 1978, MSD licensed its business to a distributor, forming a division within the distributor’s business group. In 1993 MSD was established in Singapore, with MSD Singapore taking over the Sales and Marketing function from the distributor the following year.

In November 2009, MSD and Schering-Plough merged to form one company. We are now a stronger, more diverse global organization. This not only benefits our company, but it also benefits the millions of people around the world who rely on our products and expect us to continue to deliver exceptional value.

MSD is now a leader in a broad range of areas, including cardiology, infectious diseases, diabetes, respiratory, vaccines, women's health, sun care and animal health, and we are also expanding our offerings in other areas, such as neurology, oncology and dermatology.

Today, we are building a new kind of healthcare company – one that is ready to help create a healthier future for all of us.
