Halsey Drug Co.

Halsey Drug was a generic pharmaceutical company primarily engaged in the development, manufacture, and marketing of a wide range of generic prescription and over-the-counter drugs. Founded in 1935 and based in Brooklyn, New York, the company specialized in solid oral dosage forms and liquid pharmaceuticals across various therapeutic categories, including analgesics and anti-infectives. During the late 1980s and early 1990s, Halsey was a central figure in the generic drug scandal involving the FDA, which led to significant regulatory challenges and restructuring. The company eventually shifted its focus toward more complex generic products and contract manufacturing before being integrated into larger pharmaceutical entities.
