Fenfluramine and phentermine when prescribed or ingested together are weight loss drugs popularly known, advertised and referred to as "Fen-Phen." The drugs are commonly prescribed in combination with each other and with dexfenfluramine. dexfenfluramine is promoted under the name "Redux." Fenfluramine is also promoted under the name "Pondimin." Fenfluramine and Dexfenfluramine contain essentially the same active ingredient. The combination use of these three drugs is not approved by the United States Food and Drug Administration (FDA), but was not illegal when these drugs were on the market. Doctors are generally permitted to make "off-label" or non-approved uses of drugs if the drugs are approved for any use.
Fenfluramine, phentermine and dexfenfluramine are chemically related and affect, among other things, brain serotonin levels. According to the Mayo Clinic, (FN1 html) fenfluramine changes the brain chemistry to suppress appetite. Phentermine interferes with the pulmonary clearance of serotonin. In summary these drugs make individuals feel as if they are not hungry even though they have not eaten and help individuals feel as though they have energy when the lack of food otherwise might make them feel fatigued.
Fenfluramine and phentermine were not designed for use for more than a few weeks. Dexfenfluramine was designed to allow a longer term use. However, none of these drugs have been determined safe for long term use and some physicians have questioned their usefulness at all since they do not address the root cause of obesity or excess weight and most individuals regain the lost weight upon discontinuation of the drug use.
