What is the relationship between PPH and Fen-Phen?
In 1997, the Mayo Clinic released a study linking the diet drug combination known as Fen-Phen with heart disease, including PPH, or Primary Pulmonary Hypertension, a potentially fatal disease. Between 1994 and 1997, millions of Americans had used Fen-Phen. In September of 1997, the FDA withdrew Fen-Phen from the market.
