It is only recommended to be prescribed for short term use (usually about 12 weeks), and never as a long term solution.

It is classified as an anorectic, an agent which diminishes the user’s appetite by causing the brain to stimulate the adrenal glands to produce and release nor-epinephrine, the neurotransmitter responsible for the fight-or-flight response, thus diminishing feelings of hunger.

In addition, it stimulates the release of serotonin and dopamine, though to a lesser degree than of nor-epinephrine, but still to an extent which helps minimize cravings. In essence, this medication works by stimulating the release of brain chemicals to convince the mind that the body is full, resulting in the user eating less, and thus losing weight.
