Phentermine Overview

What is phentermine?

Phentermine is one of the class of amphetamine drugs. It is used as an appetite suppressant, prescribed together with a change in diet, light exercise and counseling to help people reduce their weight. The guidelines used by healthcare professionals are to limit access to this drug. There are two consequences. Prescriptions should only be given to people who are at risk of serious medical problems because of their excess weight. This means individuals already have a high body mass index (BMI) and so are at risk, or they already have problems of high cholesterol and hypertension. Further, because of the risk of side-effects, phentermine should only be used for short periods of time.

Although this drug can be obtained through the internet without a prescription, people should always follow the instructions given by the online pharmacist. The best course is to lose weight slowly and stay safe. The human body builds up tolerance for this drug fairly quickly and it will seem to become less effective. Never give into the temptation to increase the dosage without first discussing it with your physician. It is important to note that, in many countries around the world including the U.S., this drug is a controlled substance. This affects the way you should keep the drug and whether you should carry it around with you outside the home.

How does phentermine work?

Phentermine is one of the class of amphetamine drugs and it is designed to affect one specific group of neurotransmitters (the chemicals that carry messages around the brain). There are two competing explanations for how phentermine suppresses appetite. The first is that it modifies the messages from the stomach to trick people into believing that they are full. Under normal circumstances, it takes about half an hour for the stomach to signal it is full. When using this drug, the message may be sent more continuously. Thus, people do not feel hungry and so eat less. The second explanation is that it triggers the fight-or-flight mechanism. When people experience fear, the body releases adrenaline. This gets people ready to run away or fight if the danger proves real. To make sure all the senses are available for scanning the surrounding environment, hunger is suppressed. There must be no distractions if people are to survive.
