What You Need To Know

To start off with, Adipex is a brand-name, prescription drug, which is more commonly known as phentermine. This product is similar to an amphetamine and assists by affecting the central nervous system to control appetite. It is also known as Adipex-P and it must be obtained through a licensed physician. However, this weight-loss pill is typically only prescribed to people who are considered obese or have a body mass index of 30 or higher. A general dosage of Adipex is 37.5 milligrams. A healthy diet and exercise plan are recommended to optimize results.

Adipex has been available since 2012 and proper dosage is regulated by physicians. Furthermore, a healthy lifestyle is encouraged with this diet pill, and there is a lot of customer feedback posted online for Adipex, but read on…

Side Effects – “Dangerous?”

The first issue we had with this one was the potential for Adipex side effects. According to our Research Editor, “After sorting through the facts and Adipex results, it is evident that this diet drug can lead to some serious adverse reactions. These include depression, shortness of breath, chest pains, high blood pressure, anxiety, irritability, swelling in ankles or feet, confusion and severe headache.”

One dieter stated, “The problems I’m having are: Rapid heartbeat (flutters), feeling a little weird (i.e.; throat feels numb at times, and mouth. I sometimes feel like I’m having a sugar attack (I grab OJ and Peanut butter). I can’t stand things around my neck (shirt) b/c I feel like I’m choking.”

“My experience of the ten days I used it… Irregular heartbeat, debilitating migraines, extreme mood swings and less sleep,” said another user.

Customer Complaints – “A Lot”

We took a look at consumeraffairs.com and noticed a long list of customer complaints regarding Adipex diet pills. In fact, one dieter said, “EMTs transported me to the ER in which I originally was diagnosed with a mild heart attack, but later reduced to a very rapid heart palpitations, thankfully.”

Another dieter complained, “It gave me the worst headaches, super hot angry and would forget things as well as sweaty and my hands would get so cold like Popsicle.”

Our research has revealed that if there is a certain aspect of a diet pill that is very bothersome or concerning (too many side effects, a lot of customer complaints, a difficult exercise) the chances of real weight-loss results for the long run are slim. This means if Adipex does in fact result in some unhappy dieters, that could be enough to turn people away.

The Science – “Proven?”

There is some documented clinical research that supports Adipex as an effective appetite suppressant and weight-loss treatment. This diet drug is regulated by the FDA and it is only available through licensed doctors. Therefore you must qualify for Adipex before it can be prescribed to you for weight reduction purposes.

What Users Are Saying

"”I have felt a loss in appetite nothing extremely noticeable but enough to continue using this product! But these pills are amazing!!! I’m on day ten and I can see a bit of difference on how my pants fit a bit better.”"

"”Are not as effective for me. I have taken the pills for over a week and my appetite has not changed.”"

"”This does keep me awake with the caffeine, and they made me have to urinate a lot more frequently the first day I used them, which I thought, great, i’ll get rid of some water weight….but then, nothing.”"

The Bottom Line – Does Adipex Work?

Well ladies and gentlemen, is this one you should run out and buy? We are glad to see that Adipex is regulated by medical professionals, but we don’t feel comfortable encouraging people to use this drug. After all, there are clearly a lot of drawbacks to consider. The side effects are just too extreme. Furthermore, this diet pill is not suitable for people with a BMI of less than 30, which means a lot of dieters won’t be eligible to take Adipex.

If you need to lose more weight and slim down fast, we recommend you try a diet product that is backed by plenty of positive customer reviews and does not contain any dangerous ingredients.

Among the best products we’ve seen this year is one called Dietspotlight Burn. Its formula is a unique blend of four proven ingredients, which have been shown in documented clinical research to elevate metabolism and improve fat loss results. You should also be aware that we can’t find any complaints of harmful adverse effects and user feedback posted online reveals people are seeing substantial results.

Also, the makers of Dietspotlight Burn are so confident in their product they’re offering a Special Trial Offer, which is a good sign.
