Phentermine for weight Loss
Phentermine is used medically as an appetite suppressant to patients who are unable to curb their appetite them self.
Phentermine is approved by FDA as an appetite suppressant to help reduce weight in obese patients when used short-term and combined with exercise, diet, and behavioral modification. It is typically prescribed for individuals who are at increased medical risk because of their weight and works by helping to release certain chemicals in the brain that control appetite.

Phentermine is used for the short-term treatment of obesity.
Generally, Phentermine appears to be relatively well tolerated. It can produce side effects consistent with its catecholamine-releasing properties, e.g., tachycardia (increased heart rate) and elevated blood pressure, but the incidence and magnitude of these appear to be less than with the amphetamines. Because Phentermine acts through sympathomimetic pathways, the drug may increase blood pressure and heart rate. It may also cause palpitations, restlessness, and insomnia. Additionally, Phentermine has the potential to cause psychological dependence. After short-term use, tolerance begins and can be followed by rebound weight gain.
Cardiovascular side effects include palpitations, tachycardia, and elevation of blood pressure. In the central nervous system, it can cause overstimulation, restlessness, dizziness, insomnia, euphoria, dysphoria, tremor, and headache. Its gastrointestinal effects include dryness of the mouth, unpleasant taste, diarrhea, constipation, and other gastrointestinal disturbances. It may also cause allergic effects - urticaria and changes in libido.
Its less common, but more severe, side effects include:
Phentermine use is contraindicated in those who are:
Medicines which may interact with Phentermine, such as dexfenfluramine, fenfluramine, furazolidone, or MAOIs (e.g., phenelzine) are contraindicated because of the risk of serious side effects, such as increasing headache, high blood pressure, slow heart rate, elevated temperature, or possibly fatal lung problems, may be increased. Guanadrel (Hylorel) or guanethidine (Ismelin) effectiveness may be decreased by Phentermine. Antacids may decrease the excretion of Phentermine. Carbonic anhydrase inhibitors (acetazolamide, dichlorphenamide, methazolamide) may decrease the excretion of Phentermine.
Mechanism of action
Phentermine works on the hypothalamus portion of the brain to stimulate the adrenal glands to release norepinephrine, a neurotransmitter or chemical messenger that signals a fight-or-flight response, reducing hunger. Phentermine works outside the brain, as well, to release epinephrine or adrenaline, causing fat cells to break down stored fat, but the principal basis of efficacy is hunger-reduction. At clinically relevant doses, Phentermine also releases serotonin and dopamine, but to a much lesser extent than that of norepinephrine.
Dosing and administration
Generally, it is recommended by the U.S. Food and Drug Administration (FDA) that Phentermine should be used short-term (usually interpreted as 'up to 12 weeks'), while following nonpharmacological approaches to weight loss such as healthy dieting and exercise.
