American Home Products Corporation, operating as Wyeth before its 2009 acquisition by Pfizer (CIK 5187), was a diversified pharmaceutical company headquartered in Delaware with a December 31 fiscal year end. The company manufactured a broad portfolio of prescription drugs including Inderal, Ovral, Premarin, and Effexor, along with over-the-counter medications such as Advil, Robitussin, and Preparation H. Wyeth also held significant positions in vaccines through its Lederle division and animal health products via Fort Dodge. The company faced material litigation risks, particularly from weight-loss drug settlements exceeding $13 billion following the 1997 withdrawal of Redux and Pondimin.
