A World-Class Company

MSH Pharma is a private Canadian company that develops and manufactures suppositories, vaginal ovules, and liquid products. Within this specialty, we are known for having the largest manufacturing capacity in North America, both for brand-name and generic drugs.

MSH Pharma is a subsidiary of Endoceutics, a company that specializes in women’s health as well as the prevention and treatment of hormone-sensitive cancers. The success of the Intrarosa® prasterone vaginal ovule, Endoceutics’ flagship product, was the springboard for MSH Pharma, which has manufactured this prescription product since 2017. This product has allowed us to establish industry-leading expertise in development, manufacturing and packaging, while cementing our credibility on the world stage.

Driven by a result-oriented approach and commitment to effective solutions, MSH Pharma already has an impressive portfolio of partners and continues to grow.

Our Story

A site with a rich history.

MSH Pharma is the result of a series of mergers. It all started in 1994 with the creation of Axcan, which became Aptalis in 2011. In 2015, the site became the property of Adare, which was in turn acquired by MSH Pharma in 2017.

Since then, MSH Pharma has taken pride in being named in honour of our majestic neighbour, Mont Saint-Hilaire.

We are lucky to be able to design and produce high-quality pharmaceutical solutions while facing out on Québec’s largest urban nature reserve—and an endless source of inspiration. Today, our plant spans more than 115,000 square feet and is home to our manufacturing, development, packaging, analytics, and warehousing operations.
