Phentermine is approved as an appetite suppressant and is used to help reduce weight. This is done with obese and over weight patients for a short term use and is combined with exercise and diet. Usually this drug is only prescribed when an individual is at increased medical risk because of being over weight. Phentermine works by releasing chemicals in the brain which eventually help to control appetite. Anorectics or appetite suppressants are dietary supplements or drugs that help to reduce the appetite of person and thus resulting in the person eating less.



Phentermine is usually available in a tablet form. It is used in the short term for controlling and fighting obesity. It may come in various colors and in tablet or capsule form in dosages of 15, 30 and 37.5 milligram. Phentermine works by suppressing appetite through central mechanism. This mechanism causes the brain to send out signals and curb appetite. However studies are still on to prove the actual truth behind this mechanism.

Phentermine is supposedly best effective when taken on an empty stomach. Usually doctors and dieticians suggest or prescribe this medicine one hour before breakfast in the morning. It may or may not cause sleeplessness, depending on how much trouble you were having before you started taking Phentermine. However this dosage should only be taken as prescribed. It is given for a short period only and should not be taken more often or longer than directed as it may lead to side effects and other disorders. Also Phentermine should not be taken in combination with any other appetite suppressant medicine. Phentermine has proven to be an effective therapy for the obese individuals. It has helped them lose weight and hence decrease the risk of diseases which are associated with being highly overweight. However the magnitude or amount of weight loss depends on the level of concomitant caloric restriction along with healthy exercises.

As mentioned earlier Phentermine is a short-term drug. It will initially help you to start losing weight and works till you are ready to do the same, on your own. But after a point of time the body builds up resistance to the effects of the drug. Thus the drug should be stopped after a few weeks of treatment. However to keep in mind that Phentermine alone cannot help you loose weight till combined with a healthy diet and a proper exercise routine.

Some people may experience side effects after taking this drug like blurred vision, dry mouth, sleeplessness and stomach upset. But these occur only temporarily and fade away after the first few days once the body adjusts to the medication. There are rare and adverse effects for some individual but that is a rare case and occurs when another drug is combined with Phentermine that leads to such reactions. Apart from this Phentermine is an effective appetite suppressant when taken under medical guidance. Always ask your doctor before taking the prescription Phentermine. Do not take another person's prescription as the dosage may be incorrect for your body.
