(verify) history the product sucrets was introduced in baltimore, maryland, by sharp & dohme in 1932. in 1966 the federal trade commission ordered merck and company to discontinue the false claims of germ-killing and pain-relieving properties for its sucrets and children's sucrets throat lozenges. in 1977, it was acquired by beecham, later merging with smithkline beckman in 1989 to form smithkline beecham. by 1994 the brand switched from a metal container to a plastic container. smithkline beecham, after announcing a merger with glaxowellcome to form glaxosmithkline, sold the brand in 2000 to insight pharmaceuticals. in 2011, sucrets reintroduced their product back into the familiar tin due to popular demand and nostalgia.
