Phentermine is a prescription medication that is primarily used for short-term weight loss in people who are obese or overweight. It works as an appetite suppressant by affecting the central nervous system to reduce feelings of hunger. It was first approved by the United States Food and Drug Administration (FDA) in 1959 for short-term use in the treatment of obesity. Phentermine belongs to a class of drugs called sympathomimetic amines, which work by suppressing the appetite and increasing metabolism.
Phentermine is typically prescribed as part of a comprehensive weight-loss program that includes a reduced-calorie diet and increased physical activity. It is only intended for short-term use, usually for a few weeks, because the body can develop a tolerance to its effects over time.
In the 1970s, phentermine use declined due to concerns about potential side effects and the availability of other weight loss medications. However, it regained popularity in the 1990s when it was combined with another medication called fenfluramine to create the weight loss drug Fen-Phen. The combination was effective at promoting weight loss but was later found to be associated with serious heart and lung problems, leading to its withdrawal from the market in 1997.
Today, phentermine is still available as standalone medications (Sentis, Elvenir, Obexol, Â Acxion) for short-term use in the treatment of obesity, Phentermine 37.5 is the most commonly prescribed dosage of the medication, and it is typically taken once per day in the morning. It is considered a controlled substance and is classified as a Schedule IV drug due to its potential for abuse and dependence.
