Phendimetrazine Review - 6 Things You Need to Know


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, Burn HD.

What is Phendimetrazine Tartrate?

First off, Phendimetrazine tartrate 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 Tartrate – “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 tartrate 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 tartrate, 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.

What Users Are Saying

“”This does not work!! Made me feel sick and queasy, did not care for this product at all!!!! Did not curb my appetite one bit, in fact I think I wanted to eat more because I felt so sick to my stomach from it.””

“”It suppressed my appetite but not totally. I still felt hungry at times.””

“”Most definitely gives you energy and suppresses appetite. I am currently just taking one tab 30 min before meal. So far so good!!””

The Bottom Line – Does Phendimetrazine Tartrate Work?

Now the moment you’ve been waiting for: our bottom line. First of all, we appreciate that Phendimetrazine tartrate 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 Burn HD. 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 Burn HD are so satisfied with their product they’re offering a 2-Week Sample, which is a good sign.

Phendimetrazine: What You Should Know

Phendimetrazine is a crystalline powder that's white and odorless. Also known as Phendimetrazine Tartrate, this substance is incorporated into pills in order to assist people with weight reduction. This diet product is a "phenylalkylamine sympathomimetic amine," which is similar to an amphetamine. Phendimetrazine affects the user's blood pressure and central nervous system. 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.

Phendimetrazine is only intended to be taken over a two to three month period for weight loss. It aims to suppress the user's appetite, which encourages the consumption of fewer calories. Phendimetrazine is a "phenylalkylamine sympathomimetic amine," and is similar to an amphetamine. There is some clinical research offered for this diet drug online. It's encouraged to consult a physician before taking any Phendimetrazine products and usually it is only used to treat clinical obesity, since it is a very potent stimulant. This diet pill often requires a prescription and is sold for $39.95 online, although we would not recommend purchasing this drug without a prescription.

It is not an herbal supplement like most of the pills we review. While in some ways this can be reassuring, it's wise to remember the warnings that go along with taking a pill like Phendimetrazine. Naturally some dieters would appreciate seeing an actual website with a satisfaction guarantee, some customer testimonials and free trial samples of Phendimetrazine supplements. In the end, it's definitely wise to consult your physician before considering a diet drug like Phendimetrazine. Especially since this weight loss pill can lead to side effects such as sleeplessness, dry mouth, blurred vision, upset stomach, dizziness and irritability.

  • Gabe

    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.

  • Annonomous

    Well unfortunately I am allergic to ritalin & adderall & have ADD.. its been over 20 yrs.

  • Phendimetrazine
    Gentry (Verified User)

    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!

  • Facing side effects.
    Peggy (Verified User)

    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.

      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?

  •  recommend this pill to anyone
    Jessica (Verified User)

    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.
