Original review: Sept. 12, 2019

I’ve seen so many negative reviews I felt compelled to write one (I never write reviews). At 43 yrs old I was 5’6” and weighed 145 lbs when I fell 6’ off of a ladder and, among other things, tore my ACL and broke my tibia. My injuries had me pretty much immobile for months and thanks to the injuries, combined with a move to a new state and depression, the weight started packing on. Within a year I gained 78 lbs going from 145 lbs to 223 lbs. This only increased the depression. I lived every single day miserable and uncomfortable with sleep apnea, chest pains daily (I was convinced I was going to have a heart attack at any moment) and detesting myself. I was depressed to the point where I was suicidal, even making lists of ways I could kill myself. Then January 2019 came and I was determined to turn things around. I changed my diet and was vigilant about working out.

I didn’t want the scale to define my idea of success but after a month and losing only 2 lbs (I wasn’t packing on muscle either) I was completely discouraged. A co-worker told me about Phentermine so I found a Dr and got started on my journey. I lost 20.6 lbs within my first month. My depression subsided, I felt genuinely happy for the first time in 4 years, and it wasn’t just because I was losing weight. I logged everything I ate and stayed within the 1200 calories my Dr recommended. I cut out all alcohol, pasta, rice, potatoes etc and ate really healthy. Early side effects were severely dry throat/nose, occasionally itchy and sleeplessness.

In those early days I took melatonin to ensure I got a good nights sleep. Fast forward 6 months and I have lost 70 lbs, no more depression/sleep apnea/chest pains. I do, however, have severe constipation. I try to eat a lot of fiber rich foods (which don’t seem to really help) and I drink a ton of water. I do have to rely on laxatives, which my body seems to have become a little resistant to. I started taking probiotics and those do seem to offer some relief. I would take constipation any day of the week over how I felt in January of this year. This drug has literally saved my life. It’s not a miracle drug, you have to do the work to be successful. I have no doubt I can maintain this weight loss when I wean off of the prescription because my health matters more to me than making poor food choices. The results I’ve seen with this far outweigh the one side effect I’ve had. I am so incredibly thankful for this!

Original review: Aug. 3, 2019

I am a 47 year old female who has been on the weight roller coaster for a while. A friend recommended Phentermine to me. She had great results with it. I spoke to my doctor about it, and after having the blood work and EKG she agreed to prescribe it for 3 months only. My doctor said "This will jump start your metabolism." She told me to lose 10-20 pounds in a 3 month period and then stop taking it.

My results so far are amazing. The day I started Phentermine, I also started the keto diet. I am a pro at keto... no carbs, no sugar etc.. I will be very honest and tell you the 1st day on Phentermine was very abnormal. I took the 37.5 pill very early in the morning. I didn't have time to eat breakfast. I went to work and was very jittery, dry mouth, I had heart palpitations and thought to myself "OMG I don't think I can take this anymore." I forgot to eat lunch, I had absolutely no appetite. I could not sleep on night one. On day 2 it was very different. I only experienced dry mouth. I am eating a lot less. I lost 11 pounds in the 1st 7 days. I believe a lot of that is water weight.

So I am on day 10 today. I love it. My family and co-workers have already noticed a difference in my body and face. I drink a lot of water and I am thinking about joining a gym. I have read all of the mixed reviews. All I can say is it is working for me so far. My doctor refuses to give it to anyone more than 3 months because she claims it can become addictive. So I have a 3 month window to get the weight off. So far so good.

Original review: April 6, 2019

I was a 90kg woman and I realized I need to change for the better. I have no serious health condition but I was kinda terrified when I step on the scale and it shows the weight that might bring me health troubles in the future. Most of my previous effort on losing weight doesn't work. After losing a few pounds I gained them back more. I stop taking diet pills or slimming products as I learnt that they won't do my liver good. So I went for doctor for consultation and he prescribed that I take Phentermine 30mg slow release.

Since it is an appetite suppressant I hardly feel hungry. 1st week after taking Phentermine, I experienced severe dry mouth and bad breath. There was a day I didn't realized I drank about 4L and I had muscles cramps and felt very tired due to mineral lost. I kept going to the toilet as I pee a lot. The whole week I had trouble sleeping, felt lightheaded and nausea. No appetite but super thirsty. I don't crave for anything but good thing was I still have energy. So I mostly do minor workout. I lost 4kg the 1st week. Probably lose all the water weight. I had other side effects like minor depression, headache and sometimes I felt like vomiting. Almost give up taking it on the 2nd week but glad that I kept it going until 1 month. To be honest, I don't like what I felt when I took the medicine. I felt healthier without it. But it truly shows weight reduction. After the 3rd week, my weight was 84kg. I lose 6kg in just 3 weeks.

After 30 days, I decided not to consume it anymore... I experienced the withdrawal of Phentermine effects about 2 days. I was super tired but that's it. No more lightheaded, dry mouth, nausea, insomnia. I sleep better. So I keep eating low carbs diet, exercise regularly and maintain to drink at least 2.5L a day and I still lose weight. I'm glad I don't have to being dependable on the drug anymore. 4 months without Phentermine my weight now is 72kg. 6kg to go to reach my goal!

What I wanna say here is that Phentermine is good for you to kick start your change of lifestyle if you never been on any strict diet before. It helps to train your body to endure low carb intake while provide you energy. Yes, the side effects are very unpleasant to me. Never in my life I felt such suffering. I regret letting myself gained weight in the 1st place. Never take this medicine for long term as it can be addictive and dangerous. If you experience severe headache please stop taking it and consult to your doctor as this medicine may trigger high blood pressure and other health problems. It's safer if you take it about a month and keep going fit without it then. As side effects may varies according to individual, you can do more research about this medicine. Good luck to you! May you achieved your desired weight and be healthy!

Original review: Jan. 31, 2019

I started on Phentermine couple months after deciding to make some life changes and to lose weight. I am 5'4", female, and I got careless and comfortable. I lived in my own ignorant bliss of eating whatever I wanted and saw a picture taken of me. I was horrified. I stepped onto the scale, almost 170 lbs. I took tape measurements and began my journey. I ate a balanced diet. Not extreme, not a fad, not a liquid, not anything but balanced. Carbs with protein so the body with synthesize the protein, plenty of water, and made sure to also allow a treat or two every day to keep from going insane on "cheat or treat days."

As I watched 20 lbs drop, I added in the ** at 37.5 mg per day. Huge difference after that. I felt energized, alive, and positive in the process. I believe I have undiagnosed depression. Nothing extreme or dangerous, but it was enough that I felt tired all the time, no energy, and wanted to be locked in a dark room all the time. After starting phentermine, I feel what normal and happy has always looked like to me. I feel energized and full of life. I can get things done... chores around the house, errands, work, etc and it not be a struggle every day.

Now, a couple things here. Phentermine use requires a high water intake. About 7-8 bottled waters a day while on it. The dry mouth effect that many get while on this med is fixed with water. Dry mouth and less saliva production can create a breeding ground for tooth-decaying bacteria and if you are not drinking enough water, your dentist will be the tell all. Your teeth will show the problem, as in cavities and such. Hydrate! Not just for your teeth, but because your body needs it and especially while on this med.

Also be aware that phentermine will more than likely result in a false positive for amphetamines in a urinalysis. Depending on how much you use and how long you use it will determine how it will show on a test. I took a urine screen not 20 minutes ago after taking 37.5 mg of phentermine at about 7:30 am this morning. Faint line indicated that there was a presence of amphetamine in my system, but it was not enough to create a true false positive. I showed the RX bottle to the nurse to prove legal usage of this med and saw my "A" line... very faint, but present. Lack of line indicates a positive. My overall reading was negative. If you choose to use this med, please make your employer/drug tester aware of it, as it can be a career ender if you fail a test over a false positive.

Overall, I like Phentermine a lot. I feel better, inside and out. I am functional again, happy, positive, and productive. Do not overuse it, do not abuse it, do not fail to feed and hydrate your body. This is a medical supplement, not a magic bullet. Balance out your diet, hydrate, get exercise, rest, and this will change your life for the better.

Original review: Oct. 17, 2018

I am 27, 5'2 and start weight 208.5. I had a baby 9 months ago. I struggled losing weight since my early 20s and since my family have multiple illnesses I wanted to prevent that. I spoke to my doctor about weight loss management - she addressed me that she had to run blood work and a EKG in order for me to take Phentermine. After results all came back good (No diabetes, thyroidism, kidney failure, heart problems and no high blood pressure) she said I was good to go. I took it the first day and I totally felt off - like shaky, nervous and definitely no appetite. I took early as I could in the morning (8-9 am) since it tends to last throughout the day so by bedtime it will wear off and let you sleep.

The second day, I started to consume a lot of water and ate something small and healthy to prevent the same feeling again. Thereafter, it has suppressed my appetite and my late night cravings. I replaced my addiction of soda with water. I been on it on total so far 3 weeks. I do get really bad headaches/migraines even if I do eat and rarely constipation. So far I have shed 12 lbs and that is not counting this week (week 3) and last weight check-in of 196.3. If anyone interested, I do recommend seeing a doctor first and get blood work done to prevent interaction of medications or adverse side effects! Other than that, follow instructions and read side effects just to be in the know of allergic reactions. Best of luck, God bless.

My first day taking Phentermine. I had it at 6am, fell back asleep, woke up at 730am, no symptoms. Went to work, feel fine but talked a lot more. It's been 9 hours since and I feel fine, mouth is not dry at all, no dizzy spells, no heart palpitation,s did sweat when I started to clean up. I had a power nap and don't feel starving I could eat if I wanted to but honestly can't be bothered making anything so I'll see how I feel in the morning. All I had today was peanut butter toast for dinner.

I began taking Phentermine when I was 28 years old, I needed to lose 20 pounds. The medication gave me instant loads of energy and lifted All my depression. I felt like superwoman of the universe. I was happy and full of life. I excelled at my Nursing job. The weight fell off. I had no appetite. Most of all I could work 10 hrs daily and me and my fiance could dance all night. The only disturbing side effect at the time was very dry mouth. My self confidence soared. Since the medication took my depression away after I lost the 20 lbs I continued to take it. This medication most dangerous side effects are Addiction.

Long story short I became addicted to this Phentermine. I didn't want to live if I couldn't take a lot of it daily. I got down to 89 lbs and the same Dr was still prescribed it. I lost everything in life. I overdosed hundreds of times and nearly died many times. I couldn't hold down a job. Didn't want to live anymore. I was on this horrible drug for 4 years. The Drs will lie to you and tell you it's not addictive. Trust me it is. My advice don't take this drug....

The first time I used Phentermine, I had a great experience! I am 5'2" and weighed about 145 lbs. I lost 20 lbs. after a month of use along with CrossFit exercise. My side effects were: Dry-mouth (which I thought worked out great since I needed to drink plenty of water to get healthy) and the second side effect was an insanely high libido (which initially worked out great for my husband but it got to the point where he couldn't keep up 3x a day at least for a few weeks!). I will say on my workout rest days my heart would race if I took Phentermine without working out. So I would end up jogging or using the elliptical just to sweat it out a bit!

The second time I used Phentermine was 4 years later. Same situation, had 20 pounds I wanted to shed and because my first experience was overall great I didn't think twice about using Phentermine to help reach my goal. The very first morning, pill number 1, I was very excited. Took the pill, drank plenty of water and drove to run some errands before hitting the gym. I began getting very agitated at everything, drivers, people, grocery staff, everything just drove me mad!

I got home to drop off my groceries and I began having suicidal thoughts. Mind you, aside from a little weight gain I dont have any medical issues, I dont take any other medications. I've never had any mental health problems and I've never contemplated suicide in any way shape or form! However, on this day I began to have thoughts about how everyone would be better off without me, how I'm such a failure, etc. (I am happily married with 3 well behaved kids. All honor students never given me any grief to condone me feeling this way.)

I dropped everything and told my daughter what was happening to me. She did her research and threw away the pills and kept filling me up with water in a desperate attempt to flush it out of my system. I spent the next 24 hours wanting to kill myself. Literally, planning how I should die! Wtf?! As soon as it left my system I was back to normal. My period wasnt due for another 10 days so I know I wasnt PMSing and even if I was I've never experienced such a thing. Worst day of my life! Never again! PLEASE BEWARE BEFORE TRYING THIS DRUG!!!

Original review: June 29, 2019

I lost over 40 pounds using Phentermine. This was after 7 years of failing at weight loss... I'm over 40 and pre-menopausal. Weight loss had become really hard. I had put on 50 pounds from the time i was 36 to 42. The biggest side effect I experienced was sleeping less... I would wake up at 4am and really couldn't sleep after that. But it helped my control my appetite enough to redefine my portion sizes and to start controlling my macros. I also started weight training, walking, and running every day. The drug is only one part of the weight loss equation. I've been on it for 4 months now and I feel like the side effects are getting worse (shortness of breath, dry mouth, difficulty sleeping) so I'm taking a break and seeing if I can still lose weight without it.

On half dose for 4 days. Can barely walk. I have been on Phentermine before and the only issues I had were depression, headaches, and insomnia. This time it is extreme back pain, hip pain, legs feel like lead and hurt like hell. Feet burn and tingle, arms hurt, red eyes, insomnia, and suicidal thoughts. Read some other people stayed on it with the leg pain, and then the pain was permanent! I am 54 years old, 213 pounds, active and enjoy walking, gardening, etc. I feel like I am 100 years old on this drug, walk with a shuffle because of the pain, can't hardly get out of a chair. Did I mention brain fog, 1 to 2 hours of sleep?? Horrible drug. I would rather be fat and happy than thin and in constant pain.
