Rouguier Pharma

Rougier is a historic Canadian pharmaceutical company founded in 1920 and headquartered in Montreal, Quebec. The company established itself as a leader in the Canadian healthcare market by developing and distributing a wide array of pharmaceutical products, including both prescription medications and over-the-counter (OTC) brands. Rougier was particularly well-regarded for its expertise in dermatology, antiseptics, and general medicine, with products like Herisan becoming staples in Canadian households. In 1996, the company was acquired by Sanofi, which integrated Rougier's extensive product portfolio and manufacturing capabilities into its Canadian operations. While no longer an independent entity, the Rougier brand name continues to be associated with several legacy healthcare products in the Canadian market.
