The short-term effects of using amphetamine include:

Amphetamine was first approved by the US Food and Drug Administration (FDA) in 1959 for short-term treatment of obesity. It is now the most commonly used appetite suppressant in the United States, accounting for 50% of all prescriptions, but has not been legally licensed in the UK. . Part of the reason amphetamine is so popular is that it is cheaper than other FDA-approved weight-loss drugs, sibutramine, and orlistat. It is really effective at suppressing appetite, but like other weight-loss drugs, once patients stop taking the drug, their weight will rebound. . Fen-Fen (fenfluramine and phentermine) In 1992, a mixture of fenfluramine or pendimin and phentermine caused a great uproar in the weight-loss industry. Dr. Mike Verrober of the University of Rochester published a research result. This shows that fen-fen is more effective than diet or exercise for long-term obesity. Although both fenfluramine and phentermine were approved by the FDA in the 1960s, they have not been used in combination. Trial, and neither drug was allowed to be used for more than 12 weeks. Fin-fen therapy is an example of the so-called "out-of-medicine use". Doctors legally prescribe approved drugs but use them for new purposes. Many weight-loss clinics are also willing to prescribe fen-fen, whether for general overweight or obese people. By 1996, U.S. fen-fen prescription drugs were sold for $ 18 million, but in 1997, Mayo Medical Center published a report in the New England Journal of Medicine (with a letter from the FDA to the editor describing the remaining 100 cases). Cases), announced that 24 patients developed heart valve disease after taking fen-fen, and then the manufacturer completely withdrew fen-fen from the market. The dexfenfluramine-phentermine mixture was also banned. A new blend of fen-fluoxetine and phentermine is fen-fluoxetine, which mixes phentermine and fluoxetine, but other antidepressants can also be used instead of fluoxetine. The use of antidepressants does not have much to do with depression, but seems to be used to extend the effective time of phentermine, and the dose of each drug can be reduced, so that side effects can be reduced. This is also an "off-label use", but to date, fen-fluoxetine has not caused the problems caused by fen-fen. This mixture is considered less risky because fen-fen-related heart valve disease is due to fenfluramine, not phentermine. ^[2]
