Phendimetrazine Review - Does This Diet Drug Work? Are side effects and negative user reviews deal breakers?

Editor's Review: 2.6 / 5.0
Phendimetrazine Review

No joke- over 50% of diet products simply don’t work. So what about Phendimetrazine? We at DietSpotlight took an in-depth lok, 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.

EDITOR'S TIP: Substitute Phendimetrazine with a proven fat burner such as Leptigen for better results.

What is Phendimetrazine?

To get things going, Phendimetrazine is described on drugs.com as a sympathomimetic amine, and this is similar to an amphetamine. Basically, this is a prescription drug that can be used for weight-loss. Generally this type of medication is prescribed to someone with a BMI (body mass index) of 30 or greater. It helps stimulate the central nervous system. This in turn elevates your heart rate and blood pressure, which results in decreased appetite. As for how it is taken, it must be used in accordance with your physician’s instructions. Diet and exercise are to be incorporated. Some common brand names for this drug are Adipost and Bontril.

We are not sure when Phendimetrazine was first released, but it can be acquired through a licensed doctor. This diet medication is regulated by the FDA and it typically only needs to be taken once each day, but read on…

Side Effects – “Something to Consider?”

The first thing that caught our attention about the Phendimetrazine ingredients are that they may cause some ill feelings.“There are quite a few side effects listed for this medication. The common adverse effects include; dry mouth, headache, restlessness, changes in libido, diarrhea, insomnia, constipation, dizziness, upset stomach, flushing, tremors and impotence,” says our Research Editor.

According to one user, “When night came, I was in terrible pain with my migraine. None of my usual rescue medicines worked. I was getting nervous, come bedtime, I was restless, could not sleep, had a terrible migraine all night long.”

“I just phoned my physician’s office and informed them that I plan on taking myself off of the medication because of severe constipation, headaches, insomnia, fatigue, and frequent urination,” said another person.

Negative User Reviews!

There are quite a few negative customer comments posted on the web for Phendimetrazine. In fact, one user stated, “I have been taking this medication for a week now. I had very high hopes after reading all the other reviews. I am taking it every morning, and so far no weight-loss at all.”

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

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 in 2016 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.

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!!!

    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’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.

    hello was you able to find out where to buy phendimetrazine?? please help


  • 15

    I am on 35 mg 3 x’s a day. Holy crap do I feel like I have energy! I dont even feel like eating, I have to force myself to, but I get really dry mouth. Does any body else get dry mouth? I want to drink water all the time.



    I’m afraid I won’t be able to sleep at night what hours do u take them



    I take the same dose as you. My doctor tells me to take one, 1 hour before breakfast and lunch and the third about 5-6 hrs before bedtime. I have the same feeling of energy and no appetite! Took about 2-3 weeks for them to start working completely. I’m in mid week 5 and I’ve lost 13lbs. I am take Calcium Pyruvate 3x daily (2-2-2=6 total). I take these with my meals, it is a fat burner, also perscribed by my doctor. As for dry mouth, I have noticed. It is noted to take it with a “good glass of water” with every pill. Maybe that will help?



    Try a lifesaver and/or throat lozenges for dry mouth. I just started the pills and my dose is one 35mg pill daily.

    I am a 26, and started taking Phendmetrazine tomorrow will be a week. I will have to say I absolutly LOVE this diet pill. I have taken adipex before and it would keep me up, and the last few weeks of taking that it didn’t seem to help me not be hungry at all. This new pill I can tell a difference in my energy, eating, and not once has it kept me from being able to sleep. I am over weight and need to lose more than other post I have seen, so my dr has me taking Phendimetrazine 35mg 3x’s a day with a lypo-lean vitamin. Wonders have came out of this. I dont know if i’ve lost any weight yet cause I haven’t weighed. However heres an examle: for breakfast I would eat a bacon and egg bisquit, lunch would be a normal size meal that I would eat all of, and supper would be a big size meal and I would eat all of it…Now I cant even eat a whole sausage bisquit, lunch a pack of crackers or a salad is plenty, supper- half baked potato, salad, and grill chicken (half) and I’m full. So I would recommend this pill to anyone. Also I have joined a gym and love it cause I don’t feel as tired, I have (again) energy.

    I am currently taking Phendimetrazinerebut I noticed that the last prescription that I received looks much different than my last months. I have a white tablet marked X on one side and 35 on the other. I am wondering if they gave me a placebo or if it can look like this? Do you have an answer for this?
