How is Permax related to the former diet drug fen-phen?
The only relationship between Permax and fen-phen is the type of heart valve damage. Fen-phen was removed from the market in 1997 and forced the drug-maker Wyeth to pay more than $21 billion in charges to cover liabilities. Wyeth’s recalled drugs were fenfluramine, or Pondimin, and dexfenfluramine, or Redux. To make fen-phen, one or the other was combined with another drug called phentermine that is still sold by other companies. Fen phen was recalled after 6 million Americans developed heart valve problems.
