Attention Fen-Phen Users:

Fen-Phen has been marketed under the names Redux, Pondimin, Fenfluramine, and Dexfenfluramine. Serious health complications have resulted from the use of this diet drug. A nationwide class action is underway, but it is not too late to opt-out and individually pursue a lawsuit. Contact us if you have suffered as the result of Fen-Phen use.

Bottle of PillsThe once popular diet drug fen-phen was pulled from the market in September of 1997 when reports linked the drugs to valvular heart disease. Fen-phen first surfaced in 1984 when a study indicated that the combination of phentermine and pondimin could achieve weight loss when used in a low dose.

Side effects appeared to be more minimal when the weight loss drugs were used together opposed to being prescribed separately as it had been for appetite control. Fen-phen was considered a revolutionary drug that had significant weight loss results when pondimin and redux, both manufactured by American Home Products, were approved for the short-term use by the FDA for obesity. Fen-phen was never approved yet it continued to be used and prescribed.

Soon after fen-phen was pulled off the U.S. market lawsuits began to be filed throughout the entire country. American Home Products (AHP) had knowledge of the research and adverse drug experience reports on both pondimin and redux, yet did not warn patients of the health hazards. Only when the FDA began an official investigation of what the AHP knew about the risks like valvular heart disease that was associated to the drug did fen-phen get pulled from the shelves.

By the time fen-phen was removed from the U.S. market millions of people had already taken the drug. The health complications that resulted from the use of fen-phen are serious and deadly conditions, including valvular heart disease and primary pulmonary hypertension.

Right now there are numerous fen-phen class-action lawsuits underway that do not cover the extensive health complications that have resulted from the use of the diet drugs. If you have questions regarding your legal rights with fen-phen and the health complications you have endured as a result of the drug, please contact us.

Patients suffering from Primary Pulmonary Hypertension (PPH) caused by Fen-Phen are NOT involved in the Nationwide Class Action Settlement Agreement with American Home Products. PPH patients must file independent lawsuits to make legal claims. To learn your legal rights, please contact us and speak with a PPH Lawyer for lawsuit information!

Opting-Out of The Initial Fen-phen Class-Action Lawsuit

The initial opt-out period before March 31, 2000 had less than fifty thousand claimants fill out paperwork. The majority of cases did not opt out by March 30, 2000, and it is these people that make up Round Two of the fen-phen litigations. There is a brief window where claimants can register with the Settlement Trust and request and then either request benefits or opt-out and return to the civil litigation system. An individual must meet certain medical parameters within the next year and file specified documents with the American Home Products Settlement Trust shortly after that in order to receive any type of substantial benefits from the Class Action.

Fen Phen Drugs

  • Pondimin Pondimin was the first drug used in terms of the “fen” part of fen-phen. The drug’s active medication is called fenfluramine and was manufactured by American Home Products. Pondimin and the drug redux are linked to causing left-sided valvular heart disease and primary pulmonary hypertension.

  • Redux Redux has the same effect as the drug pondimin. Redux’s active medication is dexfenfluramine, basically identical to fenfluramine. American Home Products manufactures redux as well. Both pondimin and redux have resulted in the same adverse health problems.
  • Phentermine Phentermine was manufactured under different names and has been the drug that has produced the most immediate visible side effects that were the opposite of pondimin. Fleuramine is a downer and phentermine is an upper so when combined the physicians could keep patients on pondimin longer than when it was used alone. Phentermine has not been involved in litigation and was used as the facilitator to fenfluramine and dexfenfluramine when using fen-phen.

  • Fen-Phen The combination of pondimin and phentermine became in demand immediately after being introduced. Pondimin alone had been on the market for a while and did not have the popularity of the two drugs together because phentermine was able to cancel out the sleepy side effects of pondimin. Fen-phen has found itself in the middle of lawsuits ever since the relation to valvular heart disease or pulmonary hypertension injuries resulted.
About Primary Pulmonary Hypertension

Primary pulmonary hypertension (PPH) is a rare, serious, and life threatening condition in which the blood pressure in the arteries of the lung is extremely high excluding other diseases of the heart or lungs. There is no known cause of PPH but it is linked to the use of fen-phen. PPH develops in response to increased resistance to blood flow and the increased workload that is caused by the resistance causes the right side of the heart to become enlarged. This condition can eventually lead to progressive heart failure, a disorder where the heart loses the ability to efficiently pump blood. Read More . . .

“FDA Doc Claims Fen-Phen Cover-Up,” April 7, 2000

-CBS News

Diet medication fen-phen is linked to heart ailments and is accused of covering up problems with the drug. The drug fen-phen, manufactured by American Home Products was removed in 1997 from the market for the health complications that arose. Dr. Leo Lutwak was the FDA’s key reviewer of fen-phen and thinks that the company knew about the problems prior to fen-phen being pulled from the market. The FDA was not allowing Dr. Leo Lutwak to testify and Lutwak claimed he would retire so that he would be able to testify in fen-phen cases. American Home Products settled $4.83 billion for more than 11,000 fen-phen lawsuits, which is the biggest product liability settlement ever while still admitting now wrongdoing.
