Phentermine: An Updated Review of Dietary Pills in 2020


Phentermine is one of the most prescribed medications for weight loss. A diet plan and regular exercise is the key to losing weight, but this may not be enough for over-weight people. Drugs such as Phentermine serve as a complement for weight loss strategies.

As with other medications, it’s necessary to understand how this drug works. We’ll explain the benefits, side effects, dosage, and a review. We’ll also review other phentermine-like pills.

What is Phentermine?

Phentermine is a prescription drug for weight loss. Approved by the FDA in 1959, you use alongside a diet plan and regular exercise.

Phentermine is often prescribed for obese and overweight people when diet and exercise are not sufficient. It’s used for a short period, up to 12 weeks, after which the effect begins to decline.

Phentermine is similar to amphetamine, so classified as a controlled substance in many countries. It’s available only with a prescription.

Manufactures market it under many brand names, such as Adipex-P, Qsymia, and Lomaira.

How does Phentermine Works?

Phentermine is an appetite suppressant. It reduces the feeling of hunger and makes you feel full, so you eat less. When you eat less over some time, you lose weight.

This drug may work by releasing neurotransmitters like norepinephrine and dopamine. These neurotransmitters send stimulus to the central nervous system to reduce the perception of hunger.

It may also stimulate release of neurotransmitters – epinephrine and norepinephrine, to increase the amount of energy your body uses.

Phentermine diet pills work for the short-term. After some time, your body may begin to build tolerance against the appetite-suppressing effect. When this happens, you should discontinue usage.
