Diet medicine is a kind of medicine with weight loss effect. With the change of aesthetic concept, a drug that can make people lose weight has been derived. Because it can make the body faster and slimmer, it is loved by people who need to lose weight. It should be reminded that there are strict medication standards in clinical medication, including considering medication safety and possible side effects of drugs, and adjusting dosage according to individual differences and disease development. Taking diet pills without the guidance of a doctor, using drugs that are not listed in China or taking drugs containing ingredients prohibited by the state are all high-risk behaviors. Therefore, please don't blindly follow the trend, and you must take the medicine under the guidance of a doctor. The research and development of diet pills is difficult, resulting in few new drugs on the market for many years. Although lorcaserin and Qsymia have been developed for many years and have been repeatedly reviewed by FDA, they still have to face the test of drug safety. At present, there are many kinds of slimming drugs in clinical trials or experimental studies.
