Phentermine is a type of appetite suppressant that is designed for treatment of obesity over the short term.  However, few studies have been conducted about the long-term use of the drug.  Promoters of the drug say that it should be used in connection with diet, exercise, and behavioral therapy in order to promote weight loss.  

It is most appropriate to use phentermine under a physician’s care.  The average dosage tends to be 30 mgs each day.  When first initiating phentermine treatment, it is recommended that an individual purchase a small number of pills as a test, beginning with the lowest dosage.  

Phentermine has been approved for short-term treatment of obesity, meaning six to twelve weeks.  In order to continue to lose weight and to help maintain weight, individuals must follow an effective diet plan, exercise regularly, and change those behavioral habits that lead to weight gain. 

At the present time, there is no clinical study that measures how long phentermine remains in the body after an individual ceases treatment.  So, if you’re wondering whether phentermine will stay in your body once you stop taking it, you should know that there is no clear answer to the question.     

The active ingredient in the medication is phentermine hydrochloride.  It is not known whether the drug can cause long-term damage to the major organs of the body, since there have been no clinical findings on the long-term effects of phentermine.  It should be noted that phentermine does not contain the highly controversial component known as ephedra—in fact, ephedra is a different chemical substance. 

Still, there are certain side-effects that can occur within the first week of using phentermine.  For instance, you might experience blurred vision, sleeplessness, irritability, stomach upset, constipation, or drug mouth.  The medication can also increase your heart rate and blood pressure.  Backers of the drug say its main advantage is that it works as an appetite suppressant. But it must be noted that suppressing your appetite is not a healthy way to lose weight. 

Some might wonder whether using phentermine is preferable to using hydroxycut, metabolife, or similar substances.  Medical experts say the answer depends on your own health history and how your body reacts to the various medications.   However, phentermine is not recommended for those who suffer from heart disease, high blood pressure, glaucoma, thyroid trouble, anxiety disorders, diabetes, or epilepsy.   You should also abstain from phentermine if you are taking monoamine oxidase inhibitors to alleviate depression.  Experts also recommend that you check with your doctor if you are pregnant or are nursing before you take phentermine. 

It should be pointed out that phentermine is one of the oldest Food and Drug Administration-approved weight loss drugs on the market.  It is also less expensive than other diet pills, which has led to its widespread use.   

 The pill is primarily recommended for individuals who are dieting and exercising, yet still have difficulty achieving their ideal weight.   It is marketed to people who have a major weight problem.
