Preparation H dates from about 1935. It was originally packaged in a tube like toothpaste, with a similar consistency. The company most recently named Wyeth was incorporated in 1926 as American Home Products, or AHP, and "one of AHP's earliest prizes was the acquisition of a sunburn oil in 1935 that the company transformed into Preparation H, which became one of the world's best-selling hemorrhoid treatments."  AHP changed its name to Wyeth in 2002. Wyeth was acquired by Pfizer in 2009.
