About Duchesnay USA

In 1970

Duchesnay started as a family-owned pharmaceutical company in Canada. In the late 1980s, a family member experienced a difficult pregnancy, but was unable to obtain treatment due to a lack of information regarding the safe use of medications in pregnancy.

In 1992

Duchesnay officially shifted its focus toward developing medications that are safe for use during pregnancy, thus becoming the first pharmaceutical company dedicated to safeguarding the health of pregnant women and their unborn babies.

In 2011

Duchesnay expanded to the United States and established Duchesnay USA to provide American women with access to a safe and effective treatment option for nausea and vomiting of pregnancy (NVP), commonly referred to as morning sickness, when conservative management fails.

Duchesnay today: A company dedicated to women’s health at every stage of life

Today, Duchesnay continues to evolve as a research-based pharmaceutical company whose primary goal is to improve women's health and quality of life during pregnancy and breastfeeding, while reducing the number of birth defects and minimizing the impact of maternal medical issues on newborns.

But Duchesnay’s commitment to women’s health does not stop at pregnancy and breastfeeding. Thus, Duchesnay is broadening its portfolio of products to offer therapeutic options that meet the health and quality of life needs of women and their family members at different stages of their lives.
