MSD Ireland

MSD Ireland is more than just medicines, we invent for a more hopeful future.

MSD Ireland is one of the country’s leading healthcare companies, having first established here over 50 years ago.

In order to understand MSD Ireland, it’s important to get a sense of the Irish pharmaceutical industry and the pivotal role it plays in Ireland’s economy as a whole.

  • It’s a hugely significant sector, employing over 24,500 people directly, and approximately 25,000 indirectly
  • 9 of the world’s largest pharma companies are based here and there are over 85 pharmaceutical companies located in Ireland
  • We are the 3rd largest exporter of medicinal and pharmaceutical products in the world
  • The sector is worth €62 billion annually in exports and accounts for 50% of all EU exports

We have a dynamic and diverse team of over 3,000 employees currently across seven sites in Ballydine, Co. Tipperary, Brinny, Co. Cork, Carlow, Dunboyne, Co. Meath and Dublin and, in addition, operate substantial Human Health and Animal Health businesses.

In total to date, we have invested approximately $6 billion in our Irish operations and our annual turnover ranks us as one of Ireland’s top 20 companies.

At MSD Ireland, we work at the forefront of science and technology to advance manufacturing excellence and R&D across our Irish sites and global company network. With a long-standing footprint in Ireland, our Irish sites manufacture approximately half of MSD’s top twenty products, helping save and enhance lives in over sixty countries around the world.
