The appetite suppressant Phentermine can be used effectively only on short-term basis and must be taken as part of a regular diet and exercise program. Used properly, Phentermine can produce amazing results.

A physician must be consulted as the dosage must be strictly regulated Phentermine is usually started in small doses. Short-term use is recommended to avoid side effects such as behavioral changes. Long-term use is ineffective as the pill stops working once the body develops immunity in about 6 or weeks.

Behavorial changes in cases of too high a dosage may include side effects such as those usually associated with ""speed"" or ""uppers"". This makes a person erratic, and sometimes makes them feel sharper or smarter. These of course are just illusions of the chemical. Be very careful, and don't just take the doctor's word for it when you research phentermine. Because of the decreasing effects over time, you may feel tempted to self-administer an increased dosage for the same effect. This can be disastrous. Always follow the directions, and never take more than is neccesary to lose weight.

Phentermine, like other amphetamines, confuses the neurotransmitters connected to the brain. As a result, the brain does not receive a hunger signal. This succeeds in reducing the appetite as the brain sends out satiation signals instead of hunger signals. The brain gets a wrong message of satiety due to the raised leptin levels. Overall results include loss of appetite, more energy expenditure and ultimately weight reduction due to decreased fat stored in the body.
