Bontril Review - Does This Prescription Diet Pill Really Work? Are side effects and user complaints deal breakers?

Editor's Review: 3.0 / 5.0

BontrilWe’ve heard a lot of buzz about Bontril, so we dug deep and created a comprehensive review, closely examining the side effects, ingredients, clinical studies and level of customer care. We also focused on hundreds of user responses that are posted online. Finally, we compressed and summarized to give you the bottom line.

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

What You Need To Know

First off, Bontril is a prescription weight-loss drug that is intended to treat obesity in women and men. This pill is typically taken once each morning, 30-60 minutes prior to breakfast. A low-calorie diet plan is encouraged with Bontril. The generic name is phendimetrazine and it is a sympathomimetic amine. This is similar to an amphetamine and it works by stimulating the central nervous system, which elevates blood pressure and heart rate. This in turn reduces your appetite.

This diet drug has been around since 2007. The dosage is regulated by your doctor. A healthy lifestyle is encouraged and exercise is often recommended as well, but read on…

Side Effects – “Look Out?”

The first thing dieters may want to consider is the risk of Bontril side effects. According to our Research Editor, “Bontril has a long list of adverse reactions that can occur. These include impotence, dry mouth, constipation, low sex drive, diarrhea, flushing, upset stomach, insomnia, tremors, headache, restlessness and dizziness.”

One user stated, “Experienced severe constipation, headaches, insomnia, fatigue, and frequent urination.”

“Had a terrible migraine all night long, like the Bontril wouldn’t wear off. I almost went to urgent care for my head since Imitrex was not working,” said another dieter.

User Complaints – “Not Good”

We noticed a number of customer complaints regarding Bontril tablets. Many are associated with problems with Bontril ingredients. One dieter commented, “I am taking it every morning, and so far no weight-loss at all.”

According to another user, “Serious restlessness and insomnia, can’t get to sleep.”

Our research has shown if there is one specific aspect of a diet pill or weight-loss program that is very burdensome (a lot of side effects, too many user complaints, a difficult exercise) the probability of real fat-loss results is low. Therefore, if Bontril use does result in negative customer feedback, this could be problematic.

The Science – “Effective?”

Bontril is backed by some clinical studies. This drug is regulated by the FDA and it has been tested to treat obesity. This is good, because we at DietSpotlight like to see actual documentation of scientific research that supports the product. If there is none at all, we often see a big red flag.

The Bottom Line – Does Bontril Work?

Well now, has the time come to rush out for this one? It’s good to see that Bontril is regulated by doctors and pharmacists. This way you do not have to worry about the correct dosage. Then again, we are certainly leery of all the side effects that can occur while taking this drug. You should also be aware that Bontril is only intended to be used for a short period of time, so it’s not a long-term solution for weight management.

If you’d like to see more significant fat loss results, we advise you to go with a diet pill or weight-loss supplement that does not lead to side effects, is backed by solid clinical research and doesn’t require a prescription.

Among the best products we’ve seen in 2015 is one called Leptigen. This weight-loss formula offers a combination of four key ingredients, which are shown in documented scientific research to help improve fat loss and ignite metabolism. We can’t locate any complaints of side effects and user comments posted on the web express people are seeing great results.

Also, the makers of Leptigen are so confident in their product they’re offering a special trial offer, which is a good sign.

Bontril is a diet pill that aims to assist users with the weight loss process. This medication comes in the form of a capsule and is intended to be taken once each day, orally with eight ounces of water, but on an empty stomach. Bontril is sold in containers of 30, 60 and 90, and appears to require a prescription from a licensed physician. Furthermore, those who market this diet drug online state that it should be taken as directed by a doctor. Like many diet supplements and products, Bontril endeavors to suppress the user's appetite. Bontril is a "short-term" diet supplement that's intended to be incorporated with proper diet and exercise. Bontril is basically a sympathomimetic amine (similar to an amphetamine). The goal of Bontril is to stimulate the body's central nervous system, which supposedly decreases appetite by boosting the user's blood pressure and heart rate. Cautions for this product include warnings not to break crush, chew or pull apart the Bontril capsules, since this will "make the product ineffective." Some noted side effects that may occur with the usage of Bontril are as follows; dizziness, upset stomach, sleepiness, blurred vision and fatigue. Those with health afflictions such as diabetes, high blood pressure, glaucoma and thyroid issues should not take Bontril unless directed by a licensed physician. Bontril can be purchased via the web for as low as $49.95 per 30 capsules. This diet supplement is meant to be taken early in the day to help avoid any potential issues with insomnia.

Bontril is not suited for those with diabetes, high blood pressure, glaucoma and thyroid issues. Medical consultation is wise prior to taking Bontril.

While it appears to come in a simple and convenient capsule form, which makes it easy for users to take, there may be a few concerns some users would like addressed.

    I am 36 yrs old, and weighed in at 160 pounds when my doctor prescribed these for me. I’ve been taking the generic bontril for nearly 4 weeks, and I’ve lost 23 pounds so far. The first three weeks I did not exercise although I definitely had the energy, but too many obligations. After 3 solid weeks I began exercising for about an hour, three times a week. So hopefully that’ll kick things up a notch. The energy is crazy. I have to force myself to slow down at times. So I would Definitely recommend this as an appetite suppressant, mood and energy lifter. I plan to stop taking it after my next bottle is gone-so basically another month or so. Slightly worried about having those possible withdrawal symptoms that I keep hearing about. Hopefully it won’t be too bad. I’ll keep everyone posted on that.

    The brand of Bontril is remarkable and I lost weight over a 3 month period that made me feel great. The only problem is pharmacies stopped carrying the brand Bontril and I gained the weight back over a 2 year period of time. Is the brand Bontril back on the market????? The positive effects of this medication were awesome and I was so healthy. Please let me know how I can obtain brand Bontril 105mg op daily. I know my physician will gladly prescribe it for me. I am a Nurse Practitioner and I highly recommend Bontril. I had a little insomnia initially, but it subsided. Thank you so much.

    I began Bontril SR 105mg in Nov. 2007 prescribed by my Endocronologist because of my PCOS which causes women trouble to lose weight. I’m 5’9″ and weighed 235lb. I took Bontril for 5 months and lost a total of 65lbs. Not only did I get rid of weight I got rid of High blood pressure and cholestoral. I’ve gained 5 to 10 lbs in the last 4yrs but the weight has stayed off. Fortunately with not much effort. I’m proof this medication does work and with pleasure I would show before and after pictures. FYI I had no side effects but alot of energy and was able to excersise which helped me lose my last ten lbs. I know of no one that has had my same results maybe it was just my luck.



    can I get Bontril in a tablet form from you? :””(



    Can I get genuine Bontril caps or Melfiat tabs from you without an Rx?



    I have lost 43 lbs from november 27 2012 to feb 21 2013 (235-192)! I feel great. My mom has lost 70lbs. That was in 7 months. We have both been eatting low carb diets…around 20-30g a day. Little to no exercise, however we are both quite active. There is no magic pill. You have to work for it for it to work for you! Congrats on you weight loss.

    I have been takin Bontril 105 now for a total of 6 days and have lost 9lbs. The 1st few days I was a little light headed, but you have to remeber eat. I do also try to get in at least 30 min of exercise at least 3 times a week. I drink around 4 to 5 16.9oz of bottled water every day. The worse part I think is the restless nights I have had, but other than that, I say go for it.



    hi. my dr. says to take only one a day and take it by 11 am. I dont know what my weight loss is now but i weigh 217 02/09, goal 150 by 10/21.

    I have been on the generic version phenterdrazimine(idk if I spelt it correct) and I was weighed in today from my Nutritionist and have lost 10lbs …I was more then happy and a little shocked. I have tried phentermine and lost close to nothing so I would recommend it to anyone who has tried other pills and were unsuccessful.
