Phentermine is an appetite suppressant drug approved by the FDA. It has proven to be an effective weight loss drug when paired with proper diet and exercise. By stimulating the body to produce adrenaline and norepinephrine, Phentermine can make you more alert and give you the energy that your body needs throughout the day.
Doctors usually prescribe Phentermine for up to 12 weeks. After this time, the medicine may lose its effectiveness, so you won’t lose any more weight. This medicine should be used in conjunction with a healthy diet and exercise to lose weight.
It’s also important to note that you should take exactly how much your doctor tells you to—taking more will not help you lose more weight or lose it faster, but it could increase the side effects that you experience.
Phentermine is usually prescribed as a single dose of up to 37.5 mg in the morning or three doses of 8mg spread throughout the day. If you’re prescribed a single dose, you’ll take it before you eat breakfast or a couple of hours after. If you are taking multiple doses per day, you’ll take it half an hour before meals.
