American Home Products, the lead defendant in the massive fen-phen diet drug litigation, has agreed to pay more than $4.8 billion in a global settlement that will provide medical monitoring for the 5.8 million overweight Americans who took its drug in a cocktail form, as well as graduated compensation for those who actually suffer from heart valve disease as a result.

If the settlement wins court approval, injured class members will receive payments ranging from $36,944 to $1.485 million depending on their age and the severity of their injuries.
