Adipex Review - Does This Prescription Diet Drug Work?

By Summer Banks Aug 23, 2017

Adipex is not your grandmother’s diet pill, so we took the time to write a comprehensive review, examining the side effects, ingredients, scientific research and overall customer service. Plus we scrutinized all sorts of dieter comments that are posted on several Adipex reviews. Finally, we summed up all of the facts and responses we discovered to give you the bottom line.

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.

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.

Previous Adipex Review (Updated July 21, 2014):

What You Should Know

There are a number of prescription diet medications on the market these days. One of these products is Adipex, or Adipex-P. This is a stimulant that aims to suppress the user's appetite. Unlike many weight reduction supplements out there, this product is geared specifically toward men and women who are considered obese and who suffer from high cholesterol, diabetes and/or high blood pressure. A healthy diet and regular fitness regimen are encouraged with Adipex. This product is described as being similar to an amphetamine. Adipex should not be taken with other diet pills unless directed to do so by a physician.

Some of the potential side effects that accompany Adipex are impaired thinking, fatigue, withdrawal, depression, and extreme tiredness. Individuals that are allergic to stimulants cannot take Adipex pills. Furthermore, those afflicted with alcoholism, glaucoma, or an overactive thyroid gland should not take Adipex. As with most diet drugs, this one should not be taken by women who are pregnant or nursing. Some issues that may arise while taking this weight loss drug are dizziness, diarrhea, chest pain, rapid heartbeat, blurred vision and trouble sleeping. Naturally this weight reduction product should only be taken as directed by the doctor/pharmacist.

Product Features

Adipex is a prescription weight loss drug that can only be attained by seeing a licensed physician. As with most prescription drugs, there are potential side effects with Adipex which can include dizziness, diarrhea, chest pain, rapid heartbeat, blurred vision and trouble sleeping. The actual cost of this product is not revealed on an official website. Also, there are no free trial samples of Adipex, nor are there any testimonials provided on an official website at this time. Unlike many other weight loss drugs that are available to anyone over the age of 18 without a prescription, Adipex is only suitable for individuals who are obese and suffer from high cholesterol, diabetes and/or high blood pressure.


  • Adipex is a weight loss product that is only available with a doctor's prescription, and is therefore better regulated than some other diet products and supplements.
  • Information and warnings concerning Adipex are readily available online for anyone to see and review.


  • Adipex may cause dizziness, diarrhea, chest pain, rapid heartbeat, blurred vision and trouble sleeping in some users.(See Adipex Side Effects)
  • A prescription is needed to attain this weight reduction drug.
  • There is no official website with testimonials or clinical proof provided for Adipex.
  • This weight loss product is really only geared toward individuals who are obese and suffer from high cholesterol, diabetes and/or high blood pressure.


In the end, Adipex is one of many prescription weight loss drugs out there today. On the bright side, prescription products like this may be better monitored by health professionals, whereas many of the non-prescription diet supplements have less strict guidelines. Naturally it's prudent to visit a doctor if you're interested in taking a diet drug like Adipex. This way you can learn more about warnings, potential side effects, and whether or not the product is really right for you.

Adipex Side Effects:

The weight-loss market is buzzing about Adipex. We’ve taken a look at the medication, but we wanted to dig deep into Adipex side effects by looking at the ingredients and clinical research. We pored through hundreds of patient comments. Then, we condensed the info to give you the bottom line.

What You Need to Know

The start off, Adipex is the brand name for prescription phentermine. The medication is taken as one to two capsules each day and that’s supposed to suppress appetite. One positive is that you can take it with you anywhere.

The medication ingredient was released in 1959. The brand was released after that time. It is clinically proven to support weight-loss, a definite positive. You must go through online or offline pharmacies to purchase Adipex. We like that the FDA has approved it, but read on…

Hyperactivity and Headaches

The first Adipex side effects we came in contact with were headaches and hyperactivity. Often the two appeared together. “Prescription medications for weight-loss come with the risk of adverse reactions,” says our Research Editor. “Only the dieter and physician can decide if the benefits are worth it.”

“It’s a ‘crack’ pill! Facial and mouth spasms, migraines, skull/head feels fractured! CONSTANT hunger mixed with heart burn and nausea feeling ALL day,” says one patient.

“Extreme Hyperactivity (not good), dry mouth and lips, dull nagging headaches, my heart pounding in my throat,and worst of all the crashing and extreme exhaustion in early evening,” offers a dieter.

Another user claims, “Nervousness, palpitaions, chest pains, nausea, and headache are all side effects of this medicine as well as constipation and dry mouth.”

Weight Gain – “Really?”

You’d never expect an appetite suppressant to have this issue, but one of the Adipex side effects is weight gain. When your hunger disappears you eat less, but when you stop taking the medication everything goes back to how it was before you started.

“I have gained back the 50 pds i lost plus an extra 60 pounds,” says a user.

Another claims, “I’ve been off phentermine for a year now and have gained back all 40 lbs.”

One dieter even added on weight taking the pill, “I’ve been on it for 8 months & gained 20 lbs.”

We’ve found, in our research, that one issue, like negative reactions, can cause a hitch in long-term success. If Adipex side effects are not worth the benefits, dieters may stop taking the medication.

The Science

Teva Pharmaceuticals was required to test Adipex on animals and humans before being approved by the FDA. As is the case with all prescription medications, there are proven side effects and risks associated with the treatment. Some of the systems potentially affected include the cardiovascular, central nervous system and gastrointestinal. At DietSpotlight we appreciate that Adipex comes with clinical proof, but we have to take the negatives into consideration.

The Bottom Line

Our look into Adipex side effects was interesting. We like that the medication is approved for human use and that there are clinical studies proving it works to improve weight-loss, but we can’t recommend a product with a long list of potential adverse reactions. Plus, we’re concerned about the possibility of gaining after stopping the treatment.

If it’s time to shed those extra pounds, we suggest going with a formula that offers clinically proven results without the risk of side effects.

Among the best of the supplements we’ve encountered this year is one called Dietspotlight Burn. The formula, comprised of four ingredients, is a proprietary blend with published clinical support showing it helps ignite metabolism and speed up fat loss. We’ve not come across a single report of negative side effects. We did find many dieters talking about the impressive results they’re seeing.

Also, as a bonus, the makers of Dietspotlight Burn are offering a special trial offer.

I am taking Adipex. 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 DR says this IS normal. I’m a little concerned, but I’m not a Dr.


Been taking them for a while now.Everything is great for the most part however I thought I was the ONLY one in the world who got the sugar attacks! Some times I crave donuts or cookies like crazy! or something sweet period more often than not!

  Good read and good discussion

Can I simply just say what a relief to uncover somebody that really understands what they are discussing on the internet. You definitely realize how to bring a problem to light and make it important. A lot more people have to look at this and understand this side of the story. I was surprised you’re not more popular since you certainly possess the gift.|
