The Phentermine Weight Loss Drug - How Effective Is It?

With all the hype on being and staying thin, thousands of weight loss pills and products have invaded the market, often confusing consumers with claims of effectiveness and fast results. According to reports, Americans spend as much as $56 billion every year on weight loss products. Sadly, of this amount, about $6 billion is being spent on fraudulent and ineffective weight loss products.

Low standards

Scientists have expressed concern over the proliferation of weight loss pills and products in the market. According to them, most of these over-the-counter products have not undergone rigorous testing procedures like other medication pills. As a result, their actual risks and benefits remain unknown. However, the US Food and Drug Administration (FDA) has already tested and approved a few weight loss pills, including Xenical and the Phentermine weight loss drug.

About Phentermine

The Phentermine weight loss drug is a prescription drug that works as an appetite suppressant. Compared to other weight loss pills, the Phentermine weight loss drug is significantly cheaper, hence its popularity. It was approved by the FDA in 1959 as a weight loss pill, although Phentermine weight loss drug works only as a short-term treatment for obesity and should not be taken as a daily supplement. Also, there are still no significant studies to confirm the long-term effectiveness of the Phentermine weight loss drug.

How it works

Phentermine works by altering the neurotransmitters in the brain. It stimulates the hypothalamus, the part of the brain that controls the autonomic nervous system, regulating sleep cycles, body temperature, and in this case, appetite. The chemical found in the drug triggers the release if certain neurotransmitters known as catecholamines. These include chemicals such as dopamine, adrenalin, and norepinephrine. These chemicals trigger a "fight-or-flight" response in the body, which blocks hunger messages.

Recommended dosage

The FDA recommends that Phentermine be used only for up to 12 weeks. They also advise users to combine phentermine intake with exercise, proper diet, and other proven weight loss measures. Phentermine is best taken before or after breakfast, as the drug has been known to induce insomnia.

o Those with allergies to any ingredient found in Phentermine

Safety measures

Before taking a Phentermine weight loss drug, it is always best to consult a medical expert or professional. Your doctor can perform some tests to determine whether the product will work for you. If you do need to take a Phentermine weight loss drug, you have to work closely with your doctor so he can monitor your intake. Remember, Phentermine is meant for short-term use only, and taking too much can be harmful to your health.

Also, taking the drug should be accompanied by a healthy lifestyle. Phentermine alone cannot make you lose weight, at least not in a healthy way. Proper diet and exercise are still the best ways to do it. Do not rely solely on the drug to help you lose weight, because there is a danger of substance abuse.
