No joke- over 50% of diet products simply don’t work. So what about Phendimetrazine? We at DietSpotlight took an in-depth look, closely examining the side effects, ingredients, scientific research and level of customer service. Plus we focused on dozens of user comments and dieter reviews posted on the web. At last, we compacted the information we found to give you the facts you need.

Phendimetrazine Readers: Click here to find out why we're giving away samples of our product, Leptigen.

What is Phendimetrazine?

First off, Phendimetrazine in an ingredient used in prescription weight-loss medications. It’s prescribed to someone with a BMI of 30 or greater. [1] [2] The drug supposedly suppresses appetite. You’ll take it according to your physician’s instructions. Diet and exercise are encouraged.

Phendimetrazine has been used as an ingredient in weight-loss medications such as Bontril since 1982. You can only receive it with a valid prescription. We like that it’s FDA-approved and that we found some positive user comments, but read on…

Side Effects of Phendimetrazine – “Something to Consider?”

The first concern related to Phendimetrazine side effects. “The purpose of the medication is to help you lose weight, said our Research Editor. “Dieters may not be expecting the adverse reactions that come with it.” [3]

According to one user, “I was in terrible pain with my migraine. Was getting nervous, come bedtime. I was restless and could not sleep.” [4]

“Caused severe constipation, headaches, insomnia, fatigue, and frequent urination,” said another person. [5]

On the other hand, we found Phendimetrazine reviews that didn’t mention side effects.

“I have almost no side effects except for dry mouth sometimes. I drink plenty of water and I now eat very clean,” commented a customer.

User Reviews – “Negative?”

An additional concern was the negative Phendimetrazine reviews we found. One user stated, “I have been taking this medication for a week now. I am taking it every morning, and so far no weight-loss at all.”

Another commented, “Phendimetrazine just didn’t work for me. I took it for three weeks and nothing at all. Just some headaches.”

While some offered their negative experience, we found reviews of Phendimetrazine that were more positive.

“I have experienced the dry mouth, suppressed appetite, and headaches. However, none of them bad enough to make me stop yet. When I look in the mirror I am so pleased,” said a dieter.

“I have only been taking it for a couple of days and I feel better than I have in years. I have to make myself eat. My energy is great but no jitters,” said another.

Our extensive research has revealed that if there is a particular aspect of a weight-loss pill or diet program that is especially burdensome (side effects, unhappy customers, high cost) the likelihood of long-term success is minimal. Therefore if Phendimetrazine does result in a high number of negative user reviews, this could be a serious issue.

The Science – “Solid?”

Here at DietSpotlight, we like to see real clinical research that supports the weight-loss product we’re reviewing. As for Phendimetrazine, there are some clinical studies that support this diet drug and its claims, which is a plus. Even though there is some science provided to support it, we feel that the numerous side effects and negative user reviews are serious drawbacks that should not be overlooked.

The Bottom Line – Does Phendimetrazine Work?

Now the moment you’ve been waiting for: our bottom line. First of all, we appreciate that Phendimetrazine is regulated by the FDA and some positive comments are posted online about this diet drug. But we have some reservations about the numerous side effects this diet medication can cause. Also, we’re a bit leery of this product because there numerous negative user reviews posted online.

If you’d like to shed more pounds, then we encourage you to choose a diet product that does not cause serious side effects, does not require a doctor’s prescription, is safe to take daily and is backed by plenty of positive user reviews.

Among the best products we’ve seen this year is one called Leptigen. This supplement contains a proprietary blend of four key ingredients that have been shown in published clinical tests to help ignite metabolism and speed up fat loss. We can’t find any discussion of dangerous side effects and customer comments posted online reveal people are seeing solid results.

The makers of Leptigen are so satisfied with their product they’re offering a Special Trial Offer, which is a good sign.

Basically, this diet drug aims to suppress the user's appetite, which will lead to the consumption of fewer calories overall. Although there is not an official website for Phendimetrazine, this is actually a serious pharmaceutical drug that's acquired with a doctor's prescription.

Like many other weight loss products, Phendimetrazine comes with a few warnings. Individuals that should not take this diet pill are those with heart disease, nursing mothers and women who're pregnant, unless use is specifically directed by a doctor. Phendimetrazine is intended to be taken in conjunction with a healthy diet plan. This diet supplement can be purchased online for $39.95 for 30 tablets.

Headaches occur simultaneously with many ailments. There are headaches of varying degrees of intensity. Some people experience a mild discomfort. Others feel a sharp pang that makes going about their regular activities nearly impossible.

What causes headaches?

Headaches are categorized as primary and secondary. Primary headaches are the result of every-day stressors, like not getting enough sleep or food.

I just started taking phendimetrazine 3 X’s a day about 2 weeks ago but forget to take my 3rd. I was wondering if it’s ok to take my last 2 together? They are 35mg

Hi! For detailed product and usage instructions, please refer to the Phendimentrazine official website for more information.


How many pills does your doctor have you taking before each meal? I know they are 35 mg each, but my doctor only has me taking one before each meal, and my friend’s doctor has her taking two.


I started off at 167pd. , I”m not at 135 I still have no appetite and I stopped taking it 3 months ago, I’d like to put some of my way back on because i’m to thin any suggestions anyone” don’t say eat please my appetite is just not as iy use to be,,,


Hi! Please consult with your physician on how to gain healthy weight.


I was prescribed with this med about two years ago. Before taking the pill, my weight was 258 lbs. After taking the pill for four months and without doing any exsercise, I lost 42 lbs in four months. Obviously, it is not taking the pill alone. I changed my diet drastically. I cut most pf the carbs that I used to eat everyday. I didn’t eat rice, pasta nor bread in that whole time, not even a little bit. So if you want to these pills to work, you must change your diet and add some REAL excersice into your daily routine.


I have been taking this pill for a month without any exercise. O’course I get plenty of exercise at work. I have lost 2 lbs and I am not happy with that. The pill cost to much money to lose one or two pounds. This pill does not keep the up and I can barely tell that I have taken it. I still get sleepy so I can’t understand why it is keeping some people up, it just make me want to sleep


I am 64, have high blood pressure, am 65-70 lbs. overweight. Dr. prescribed Phendimetrazine 105 mg. Does anyone know if this is safe?

Candace (Editor)

Since you were prescribed this by your doctor it’s safe to assume (s)he feels the formula is safe for you.

Cindy. Your Name

I think it’s great. But you still have to watch what you eat and work out. Where can I purchase these without a prescription?

Stephen (Editor)

We do not suggest you seek to acquire this pill without a certified and trusted doctor to prescribe it.

Your Name

I lost weight, that was awesome, and then I had atrial fib & a heart attack. (only taking 1/3 of the dose)

Destiny Your Name

Did they say it was because of the phen? Did you have previous heart problems?


I use it now and hve before.phendametrazine 35mg works fine for me in conjunction with diet & exercise


I can’t take anything but Phendimetrazine tartrate 35 mg tablet. This works great for me. I would but it on line if there was a legit source. My hubby is a Texas oil man and he doesn’t like it when is love gets ripped off. With his money he can find anyone that does me wrong. But if Iam well taken care of and get exactly what will keep this trophy wife a trophy, everyone benefits. thank you kind lady’s and gents for any leads to my weightloss success!!!


Love Phendametrazine , it works great! It’s the best diet pill out there but very hard to find a doctor who prescribes it.


All diet drugs basically work the same way as stated above. They raise your heart rate and blood pressure which decreases appetite. Same thing that meth and cocaine do. Hence why speed users are usually way too thin. Diet drugs are basically clean speed in one form or another. Which is going to cause.. Jitters increased heart rate dry or cotton mouth which leads to drinking a crap load of water which in turn causes frequent urination. You’re not going to be able to sleep until the drug wears off or until you build a tolerance. And with that the other symptoms should ease as well. If you’re not prepared for these so called side effects don’t take diet drugs. These so called side effects are actually how the drug works. And if you take it long enough and give your body time to adjust you won’t even notice them so much anymore.

I want to buy product. Send me a mail.


can you break them in half. if you are sensitive to medication.


I’ve been researching that too, if you do find a site where you can purchase phendimetrazine w/o a prescription, please let me know. I know I used to purchase 180 pills for $24.91. Can you imagine. Some places like Kaiser charge $185.00 for only 160 pills??? So do most private medical weight loss centers!


A very low dose of phendimetrazine prescribed as needed by a nutritionist MD was extremely helpful in gaining focus for mild, transient ADHD several years ago.There was no weight loss, however its application for attention problems far exceeded other medications routinely prescribed for adults. There was no addiction to the phendimetrazine, it was frequently stopped suddenly with no discernible side effects or withdrawal symptoms. This off-road application may benefit others now taking more traditional ADHD medications. Aderall taken as needed on occasion has certainly had unpleasant side effects in my experience.
