preparation H

Preparation H is a brand of medications, manufactured by Pfizer, used in the treatment of hemorrhoids.

Preparation H dates from about 1935. It was originally packaged in a tube like toothpaste, with a similar consistency.[citation needed] 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." [1] AHP changed its name to Wyeth in 2002. Wyeth was acquired by Pfizer in 2009. [2]
