What is "rexall"

Rexall is a chain of American drugstores, and the name of their store-branded products. The stores, having roots in the federation of United Drug Stores starting in 1903, licensed the Rexall brand name to as many as 12,000 drug stores across the United States from 1920 to 1977. (The "Rex" in the name came from the common Rx abbreviation for drug prescriptions.)

Since 1985, it has been the name of over-the-counter drugs and drugstores in Canada operated by the Katz Group of Companies, and of health supplements in the United States. The Canadian Rexall brand is not related to the US operations.
