To help people in their weight loss struggles, and to combat potential health problems that accompany obesity, anti-obesity medications such as Fen-Phen, Fenfluramine and Phentermine are prescribed as a quick weight loss solution.

The Quick Fix for Weight Loss

So, what is it with the popular demand for these three diet medications?

The answer is, believe it or not, that Fen-Phen, Fenfluramine, and Phentermine all have amazing capabilities of suppressing your appetite and increasing your metabolism fast.

The results aren’t ordinary either; they are above and beyond what a normal pill can do.

But although these three diet drugs may be effective at helping you burn off the extra pounds, the side effects may even be more detrimental to your health than the fat-burning effect that they are capable of producing.

So despite their infamous ability to help you lose weight, you must be aware of the dangers and side effects that you risk when using these drugs.

The Problem With Fenfluramine

Fenfluramine is part of a classification of weight loss medications that are used specifically to control your appetite. This particular drug is popular because it makes you feel full which will help you not to eat when you shouldn’t.

One of the common reasons that people opt for this product is to combat their cravings when they need it most, such as late at night, which is when most people screw up their diets.

All this is possible because Fenfluramine increases the levels of the neurotransmitter Serotonin, a chemical that helps to regulate both your mood and your appetite.

But these benefits may be too good to be true. So if you are desperate to lose weight and you are thinking about taking Fenfluramine, you should be forewarned about some serious dangers.

Brief History of Fenfluramine

Fenfluramine was first introduced into the US market back in 1973 and with it was brought a number of dangers including heart valve disease and pulmonary hypertension.

Contrary to popular belief though, the damage that this drug poses on the heart valve continues long after you stop taking the medication. As a matter of fact, your chances of needing heart surgery for faulty heart valves after taking the drug are increased sevenfold.

Dangers & Side Effects: Other dangers and side effects include insomnia, nausea, heart palpitations, depression, pulmonary hypertension, and possible cardiac arrest.

Phentermine Comes with a Steep Price

Phentermine is by far the most popular diet pill on the market and also another one of the most powerful weight-loss drugs.

Phentermine is prescribed to people who are seriously overweight (clinically obese) and are in danger of serious medical problems due to their obesity.

But this powerful weight loss prescription is meant for short-term use only and works by helping your body release more norepinephrine, a neurotransmitter that helps to reduce hunger.

In addition to being a hunger suppressant, another added benefit of Phentermine is that it is also used as a fat-burning agent.

Taking this prescription helps to release epinephrine, otherwise known as adrenaline, which helps to break fat cells down in those areas that you need it most such as the lower abdominals, hips, thighs, buttocks, etc.

Brief History of Phentermine

Phentermine was first introduced to the market in the 1970s and has undergone extensive research along with numerous clinical trials.

Although relatively safer than its Fenfluramine and Fen-Phen counterparts, it is still capable of producing harmful side effects such as an increased heart rate, elevated blood pressure, heart palpitations, restlessness, and insomnia.

Another one of the side effects of Phentermine is the potential for the drug to cause psychological dependence, which may be just as bad as the others. Having any type of chemical dependency will wreak havoc on your life.

If you plan on taking Phentermine, be warned, because most of the dangers posed by taking this drug are dose-dependent, which means that the dangerous side effects will increase with the increase of the dose.

Dangers & Side Effects: Some of the less common Phentermine dangers include fever, hallucinations, tremors, restlessness, severe nausea, vomiting and diarrhea.

The Disaster Called Fen-Phen

Fen-Phen is a popular weight loss medication that is a combination of Fenfluramine and Phentermine and was first introduced in the 1990s after Fenfluramine by itself proved to be a weaker ancillary against obesity. [1]

Combining Fenfluramine with Phentermine was thought to give the perfect combination of a powerful appetite suppressant and hyperstimulant, all in one.

Unfortunately, Fen-Phen proved to be a serious disaster, causing heart valve damage and a fatal lung disease called primary pulmonary hypertension.

In 1999, a class-action lawsuit was filed against Wyeth, the makers of Fen-Phen and since then the damages filed are in the billions.

Dangers & Side Effects: Some of the less common side effects include anxiety, nervousness, blurred vision, confusion, chills, sweating, dizziness, headache, abdominal pain, or nausea.

Final Thoughts On Fen-Phen

So why would anyone want to put their health at risk by taking dangerous drugs like Fen-Phen, Fenfluramine, and Phentermine in the first place?

It all seems like a quick fix but the potential risks to taking any of these drugs for some people seem to simply be death in a bottle.

Advances in the technology of over-the-counter supplementation sure have come a long way in recent years.

There are now several products on the market today that, although will never be as effective as their prescription counterparts, are both safe and effective for appetite suppression and metabolic boost.
