Reviews for Phendimetrazine

"With phendimetrazine I have no jitters, I am finding it easy to eat less and I have more focus and an improved mood."

Nick · Taken for 1 to 6 months March 2, 2019

"I tried this years ago when I became tolerant to Phentermine. I thought this drug would be the "next step up." I took it three times daily, but don't remember the dose. It did not give me anxiety, but did gave me severe panic attacks (I know that doesn't even make sense!) I had never experienced a panic attack before this drug or since discontinuing. It did not suppress my appetite. That could have been from the cross tolerance to phentermine. I am the one who brought it to the attention of my doctor, who had never prescribed it previously. I guess there is a reason doctors don't prescribe it: not very effective with bad side effects and frequent dosing requirements."

"I have been on the 35 mg 2x a day for 2 days and I have no appetite at all. I am very focused, have tons of energy and feel amazing. I have a heart issue that my doctor is aware of and this dosage does not make me feel jittery at all. I don’t even know what my starting weight was as I was to embarrassed to look at the scale, but feel I need to lose close to 50 lbs. only negative...not tired!!!"

"This medication does NOT work. I actually eat and crave more when I'm on it. Had difficulty sleeping. And when you're off of the medication you feel depressed and extremely fatigued. I've been prescribed this medication by a bariatric doctor 2 months ago with NO RESULTS. I experienced better results from Phentermine."

Bontril Slow Release (phendimetrazine): "I've been on bontril for 2 mths now and am on the keto diet. I've lost almost 30 lbs with very little exercise. I'm very active at work and my job is physically demanding. I've noticed a definite increase in energy and I'm never hungry. The only side effects are, my balls ache, I can't poop and it's hard to pee sometimes. My wife started keto at the same time as I did without the bontril and she has lost 17 lbs and we both feel great."

"I started taking PhenD 105mg on April 3 - along with fish oil, multivitamins, and extra strength Apple cider vinegar capsules. Today is April 21, and I am down a total of 10lbs. I only have about 30lbs to go to hit my goal weight and I really feel like PhenD will help me do it. This medication makes me feel great. Improves mood and depression, is an excellent source of energy, and I have little to no appetite. Only side effect is dry mouth, which helps me to hit my daily water intake, and I've been craving fruits and veggies like crazy. Highly recommended!"

Tecuso March 6, 2018

"I took PhenD 1 a day 30 min before breakfast a year ago for 3 months- went from 168lb to 126lb in 3 mnths. It curved my appetite & gave me energy. Dr 1st prescribed Pherermine but the side affects were bad, tried PhenD & they are AMAZING! I maintained 126 lbs for a year then lost my job. Unemployed & depressed I gained 10 lbs back. NOPE! I HAVE LOOKED & FELT TOO GOOD OVER THE LAST YEAR. Just went back on PhenD yesterday & already feel it working- No more stress eating! I hope 2 drop the lbs and keep off forever! I’m 42 & with PhenD I’m in the best shape of my life. No exercise other than my regular busy schedule & my blood work has never been better. I highly recommend this to anyone who has trouble losing weight. I was tiny my entire life but after a hysterectomy I gained 40+ Other than surgery scars, I am now very proud of my body. PhenD will put 15 yrs back on your life & it’s affordable- only $29 per month w/o ins. My food intake cost more than that prior to PhenD"

Bontril Slow Release (phendimetrazine): "My wife was prescribed Bontril as she was a bit overweight about a year after having our child. Three months later, she started having significant side effects which resulted in a full blown psychosis. Despite no prior mental issues, she was diagnosed with Schizo-Effective disorder at 32 years old, very late for a normal diagnosis of the sort. Two visits to a mental health facility and four years later, she managed to return to the dermatologist who prescribed (and distributed out of his office) the medicine. Two months later she was dead. The autopsy was inconclusive and we are currently awaiting toxicology to confirm. Be very cautious of taking this medication."

"I've only taken this for a week. 35mg phendimetrazine twice a day and I don't feel anything at all. No extra energy, I'm still consuming as much coffee. In fact I have been sleeping even more since starting. It might curb my appetite a smidge if I take the tablet just in the right amount of time before a meal. Four-ish hours later though my hunger is back in full force. Usually have hunger pains then too for eating less when I ate when it mildly suppressed my appetite. No weird side effects except a chalky taste in my throat. This stuff has been pretty useless I follow up with my doctor later this week and I will be requesting something else."

Bontril Slow Release (phendimetrazine): "Took my first one after lunch and had no appetite the rest of the day"

T Clemons · Taken for 1 to 6 months June 1, 2017

"I lost weight in 2014 and kept it off until I got pregnant, I gained almost 40 lbs and it was hard to lose, I only lost 10lb on my own and wanted the doctor to give me a boost, I asked for Phentermine but he suggested Phendimetrazine would work better. NO!!! I gained weight, I ate right, worked out, didn't eat after 8 no sugars, no sodas, no nothing bad! For me it did not work. Now I am on Phentermine and I lost weight within the 1st week, I know its water weight but it is a start!"

Joeyangora April 8, 2017

"I started taking this on Feb 9, 2017. It is now April 8, 2017. Two months on this medicine I have lost 18 pounds with 11 pounds going in the first 4 weeks. At first I only took half what I was prescribed which is 2 pills three times a day. On the 4th day I was sooooo hungry I went ahead and ate a bunch of junk food, but it still wasn't what I normally ate. It has decreased my desire to eat everything I see all the time and all but killed my insatiable hunger. I have been overweight starting in 2001. I am barely 5 foot tall and weighing 209 pounds is just bad. I have thyroid disease and arthritis along with fibromyalgia and chronic fatigue syndrome. Most days it is a chore to go from my bed to the chair downstairs. This is helping me."

"The only diet pill other than Phen-Fen that ever worked."

izzy2016 · Taken for 1 to 6 months January 20, 2017

"I started taking this drug about 2 months ago and I have lost about 30lbs, it seems I can tell it more in my cloths, they are to big for me now, which is a good thing, but I had to buy more clothes. The hardest thing more me is the dr. told me to eat every 4 hours."

Adri 20 · Taken for 1 to 6 months November 1, 2016

"I just have to say taking Phendimetrazine was the only way I could lose weight. Obviously diet and walking 4 times a week for half hour. I didn't have side effects, except for dry mouth and a lot of energy, which was very good. Anyway I was with a physician-supervised weight-loss program but never I had a problem. I lost 91 pounds in five months. Simply..... amazing!"

MassieK · Taken for 1 to 6 months September 30, 2016

"I have been on Phendimetrazine as well as a natural thyroid pill since July. I have lost a total of 35 lbs, but I have changed my diet dramatically. I do not eat any bad carbs. I have also completely cut out sugar, and only drink water. I do believe that I could've lost this weight with my diet change alone, because I have already done so in the past. Now on my 3rd month, I have noticed that I am very irritable. I have been having a lot of anxiety and depression. I find myself having difficulty breathing feeling as what I am assuming is a panic attack. I feel as though I cannot swallow at times. I also find myself overcome with extreme sadness and get mad and feel violent. Also feel as I am going a little insane. BE CAUTIOUS."

"I have been taking 105mg slow release of phendimetrazine, once a day for 3 months. I haven't experienced any bad side affects. It has curbed my wild cravings & making it possible to cut my caloric intake from 3500 a day to 1500 - 1700 a day. I don't really exercise, but I get up & move & leave the house, whereas before I didn't move off the bed or couch & didn't leave the house but once a week My only problem is, I have only lost 3 pounds. I don't drink sodas, I use sugarless foods & try not to eat any bad carbs. I am basically eating meat (beef, chicken & lean pork), yogurt, green veggies & a protein drink with a banana & blueberries. I am very depressed over this. I used to eat cookies, cakes & all kinds of bad snacks, now I don't."

"I have been on PhenD since Tuesday, August 30th. It was not prescribed by my primary care physician. I decided to see a weightloss clinic and stick to a specialized plan. Originally, the physician wanted to place me on Contrave but I quickly declined that option due to the severe nausea so many people experience so she decided to place me on PhenD. I am SO glad that she did. My starting weight was 278.6 and today (3 days later) I am at 271.0! 7.6 lbs gone already! I have been following a 1400 calorie OR LESS diet since Tuesday and I walked about a mile last night. I am amazed. Thankfully, only side effect I have experienced has been cotton mouth. I suggest this medication strongly."

"I'm 33 years old 5'5" and 164 lbs. This is the heaviest I've ever been. My weight keeps climbing and I keep justifying it by buying a larger size. I really enjoy Candy I was up to 4 bars per day not including the little single pieces in the Jolly Ranchers. I used to go to a weight loss clinic which gave me 105 mg it worked wonderfully. I would take 1 pill around 10:30 am and it would curb my appetite ALL day! For the first time I did Not Crave candy! They worked Great for me. However, It came at a high price. I was paying $50 per week. So this time I went to my primary Dr. and she was able to prescribe me the same thing and I spent $3.96 with my insurance . Awesome!!! It still works I've lost 6 lbs in 5 days. Love it!"

Bontril Slow Release (phendimetrazine): "Took it for about two months (skipping doses on weekends and some weekdays due to extreme side effects), started having extreme difficulty breathing, anxiety attacks from not being able to breathe with such a tight chest. Also it made me ridiculously irritable, and mean all the time but I did lose 15 lbs on it. Most of the time I felt like I was literally going insane. Not sure it was worth it though."

"I began a weight loss program on August 29,2015 to date 01/31/2016 I am down 57 pounds and I feel great. This weight loss has really come from just eating healthier and taking a b12 vitamin in the am as well as after the first three hours of being awake a 30mg phentermine capsule. I have been kind of stuck for the last couple weeks and the kicker has been that even after eating a nice sized lunch salad I feel like I am starving. I went to the clinic on Friday and told them about being hungry in the middle of the day and they gave me a 35mg phendimetrazine to take around 1 or 2 every afternoon. I have not had any problems sleeping since they were prescribed and really haven't even had the dry mouth lately. I have started to lose again."

"So far so Great! I can't believe I found something that works for me! I'm 51 years old I have been over weight for 17 years! I was always able to control my weight before with weight watcher and Exercise but the pounds kept coming on! I got up to 250 and now I am down to 228 in 2 months!! What I can't believe is this is with no Exercise but I have Lots of energy! I do have some side effects with the biggest being insomnia so sometimes I'll skip a dose if I think I haven't been getting enough sleep and that helps some.. But the biggest part is the Energy and working all day without a nap or feeling tired! I don't want to go off it until I get to my goal weight how long can I stay on this medicine? I heard 3 months but that kinda scares me."
