Overview
A member of the amphetamine and phenethylamine family, phentermine is a prescription drug mainly intended for weight loss. It is especially indicated for overweight individuals who have been endlessly trying different natural ways to lose weight but to no avail. Because phentermine is particularly formulated for short term use, it is actually not an advisable drug to take for long term weight loss maintenance - mainly due to the risks that come with using it. Being able to know important details about phentermine allows you and your doctor to determine the most effective way to integrate the drug into your weight loss regimen.
Modes Of Action
Phentermine acts by primarily affecting norepinephrine, which is a brain chemical that plays an important role in adrenaline release. Phentermine was one of the ingredients in Fen-Phen, a weight loss drug banned from the market after it was discovered to cause life-threatening heart valve diseases in the late 90s. As of today, phentermine is being sold independently as a weight loss supplement. And fortunately, it has not been a contributory factor to serious health problems caused by its predecessor. Phentermine takes effect by acting as an appetite suppressant and metabolism booster. Its highest level of effectiveness is reached when used for a time period of about 3 months or less. It should also be accompanied by other weight loss activities such as balanced diet and exercise. The main problem with phentermine is when you suddenly stop taking it, rebound weight gain is very likely to occur. Because of this, phentermine is used only to help jump-start your weight loss mechanism and not be used for continuous weight maintenance.
Adverse Reactions
Notable common phentermine side effects are anxiety, difficulty sleeping, dizziness, dry mouth, and upset stomach. For some people, potentially hazardous side effects may include glaucoma, high blood pressure and increased heart rate.
Contraindications and Risks
Phentermine is contraindicated if there is a history of cardiovascular diseases and substance abuse. Phentermine should also not be taken together with other weight loss medications. In addition, taking phentermine does have its own share of risks to be careful of. Long term users tend to abruptly stop taking the drug once harmful side effects are experienced. This may result to withdrawal symptoms such as depression and easily gets fatigue. Psychological dependence and resuming the drug regimen without prescription will most likely happen next.
Precautionary Measures
Coordinate with your doctor before you even consider starting to take phentermine. This is in order for you to be initially oriented to the dos and don'ts while being on phentermine therapy. Follow the exact dosage prescribed to you. If and when you experience severe chest pains and headaches when taking the drug (though it rarely happens), consult your doctor as soon as possible since he will likely make you stop taking the drug.
