Adipex (phentermine) is a prescription stimulant used as a weight loss aid. As a member of the amphetamine and phenethylamine classes, Adipex helps jump start weight loss by suppressing appetite and speeding metabolism. Like other medications, Adipex can cause side effects in some people. Understanding the benefits and risks of Adipex weight loss supplements helps patients make informed decisions and reduce the risk of adverse effects.
Uses
Adipex is approved to treat obesity and other weight-related problems. It is generally reserved for severely overweight patients or those with risk factors like high cholesterol or diabetes. While the length of treatment varies from patient to patient, Adipex is often prescribed for a period of three to six weeks. It is recommended as part of an overall weight loss plan that includes a healthy diet and regular exercise.
Pharmacology
Adipex is a central nervous system stimulant with amphetamine-like effects. It speeds heart rate and breathing, thereby boosting metabolism and helping the body burn calories more effectively. In the brain, Adipex increases the production of norepinephrine--a neurotransmitter that suppresses hunger. It also stimulates the release of adrenaline and epinephrine, thereby helping break down fat stored throughout the body.
Side Effects
Adipex can cause unwanted side effects in some users. According to the National Institutes of Health, common side effects include dry mouth, diarrhea or constipation, vomiting and unpleasant taste. Adipex can cause over-stimulation, especially when combined with caffeine or other stimulants. Symptoms like insomnia, nervousness, headache and irritability may be more likely to occur when taking Adipex with other central nervous system stimulants.
Safety Precautions
Like amphetamines, Adipex has the potential for addiction and abuse. According to Drugs.com, people with a history of substance abuse should not use Adipex for this reason. Those who suffer from high blood pressure, heart disease, glaucoma or overactive thyroid should also avoid the drug. Taking Adipex in the morning or early afternoon can help prevent insomnia. Monitor your intake of caffeine and alcohol while taking Adipex, as these substances may increase the risk for side effects. Don't drive until you know how the drug affects you, and follow your doctor's dosing directions.
Considerations
Adipex is not a cure for weight problems. It is most effective when combined with other lifestyle choices like a healthful diet and regular exercise. The decision to use Adipex should be made only after discussing the risks and benefits with your doctor.
