How Does Phentermine Work in Weight Loss?

What is Phentermine?

Phentermine is a prescription appetite suppressant that, when taken correctly, can lead to safe and successful weight loss. For maximum results, however, phentermine must be accompanied by a healthy diet and regular exercise program. Taking phentermine should only be done while under a doctor's care, as the dose must be strictly regulated.

How Phentermine Works to Help You Lose Weight

Phentermine is a stimulant that helps to suppress appetite. It acts on the central nervous system in our brains to help stimulate and release certain neurotransmitters called catecholamines. These catecholamines--dopamine, epinephrine and nor-epinephrine--produce a marked effect on our nervous system, namely inducing a "fight or flight" response within our bodies. This response puts the brakes on the hunger signal within our body, so we feel satiated and eat less.

Side Effects of Phentermine for Weight Loss

Although inducing the "fight or flight" response may be good for curbing appetites, the side effects that may come with taking Phentermine may not be so pleasant. Although serious side effects don't usually occur, seek immediate medical attention if you experience hives, difficulty in breathing, swelling (especially of the lips and tongue), chest pain, heart palpitations, restlessness, confusion or dangerously high blood pressure.
Less serious side effects of Phentermine, which normally go away over time, include: feeling nervous or anxious, headache, tremors, dizziness, difficulty sleeping, dry mouth, diarrhea, constipation and itching. If you experience any bothersome side effects of Phentermine that don't go away after a few days of taking the drug, contact your doctor.
