Fen Phen Side Effects
The diet drug combination Fen Phen was recalled in September 1997 after several studies revealed a link to heart valve damage among patients who were prescribed the drugs. According to the results of a study, about 30% of Fen Phen users had abnormal echocardiograms after taking the product.
In the wake of the Fen Phen recall, researchers also found a link between the diet drugs and primary pulmonary hypertension (PPH), a life threatening condition causing high blood pressure in the artery that carries blood from the heart to the lungs. According to a study in the Journal of the American Medical Association, Fen Phen users were ten times more likely to develop PPH than other patients. Among those who had taken the drugs for longer than three months, the risk of PPH was 28-times greater.
FDA Warns of Herbal Fen Phen Side Effects Risk
In April 2004, the Food and Drug Administration also banned the sale of dietary supplements containing ephedra (ma huang)—which were sometimes marketed as “herbal Fen Phen” following the recall on Fen Phen. Announcing the ban on herbal Fen Phen, Health and Human Services Secretary Tommy Thompson said that it and other supplements containing ephedra presented an “unreasonable risk to the public health.”
The FDA has received more than 1,000 reports of side effects linked to herbal Fen Phen by the time it was pulled off the market, including at least 150 deaths. According to the agency, patients taking supplements containing ephedra faced an increased risk of serious and potentially deadly side effects, including hypertension (high blood pressure), irregular heart rate, tremors, seizures, heart attacks and strokes.
