What is Phentermine?
Phentermine is a prescription medication used for short-term weight loss. It works as an appetite suppressant by affecting the central nervous system, reducing hunger and increasing feelings of fullness. Phentermine is typically prescribed alongside a reduced-calorie diet and exercise program.
How does it work?
Phentermine works by stimulating the release of certain chemicals in the brain that affect appetite control. Specifically, it activates the release of norepinephrine, a neurotransmitter that signals the brain to reduce hunger and increase feelings of fullness. This leads to a decrease in appetite and helps individuals consume fewer calories. Additionally, phentermine also increases energy expenditure by boosting the metabolism, aiding in weight loss.
How to take it?
Phentermine should be taken exactly as prescribed by a healthcare professional. Typically, it is taken orally once a day, either in the morning or before breakfast. It is important to follow the prescribed dosage and not exceed the recommended duration of use.
Phentermine is usually taken on an empty stomach to maximize its effectiveness. It is important to avoid taking it in the evening or close to bedtime, as it can cause insomnia.
