What is Qsymia
Phentermine
The Generic name of this drug
Treatment Summary
Phentermine is a drug used to help people lose weight by reducing appetite. It was introduced in 1959 and is classified as a Schedule IV drug, meaning it has a low potential for abuse. It is related to amphetamine but does not have the same addictive qualities. Phentermine was initially combined with other drugs to create an anti-obesity regime, but was later approved as a stand-alone drug in 2012. It is typically used in short-term weight management programs and is taken in lower doses than when it was combined with other drugs.

How Qsymia Affects Patients
Phentermine is thought to work by reducing appetite and increasing the body's resting energy expenditure. In clinical studies, patients taking phentermine lost an average of 3.6 kg over two to twenty-four weeks and were able to maintain their weight after treatment stopped. Unlike other drugs in the amphetamine family, phentermine does not cause any stimulation of the central nervous system, high blood pressure, tolerance or QTc prolongation.
How Qsymia works in the body
Phentermine is a medication that helps reduce hunger by increasing levels of noradrenaline in the brain. This causes the body to enter a state of alertness, which suppresses the feeling of hunger. It also weakly inhibits monoamine oxidase, although this effect is not usually significant.
