Reviews for Phentermine to treat Weight Loss

Sort by:

"I use only 15 mg (doc prescribed 30 but I could not sleep at all with 30 mg, also it was so strong I did not have appetite at all and I would take only 300 calories per day if that much).So 15 mg works for me. I count calories I do not fo over 1400 per day, I run/walk 30 minutes per day, drink one gallon of water and eat everything in small portions like 5x per day. My snack is apples or almonds but i also eat sandwich once in a while or spaghetti or rice. The only thing I do not consume is chocolate or any other sweets. My carbs come from fruit or baked potatoe or corn... I went feom 246.5 to 229 since August 1 ( so in 25 days almost 18 lbs). I will probably lose few more until monday so I think total.of 20 lbs per.month is great."

"I Have been on this medication for 7 weeks along with doing the slim plate program. I exercise at the gym 3 days a week and my off days I walk a mile. This is not a miracle drug as with any weight loss you have to watch your food intake. I weighted 164 pounds 7 weeks ago,and I'm at 147 now. It has helped a great deal with controlling my appetite. I have tried it all,but this is working and I'm feeling much healthier."

"I got hives from taking phentermine. The itching is unbearable and won't go away, even weeks after having quit taking this horrible drug. Thousands of other people have reported the same reaction online -- which I discovered after it happened to me too. It's not worth the weight loss! Quit before you have this terrible reaction happen to you."

Adipex-P (phentermine): "47 yr old male, 6'3, beginning weight in 2012 was 280. Before prescribing, my doc thoroughly checked for a healthy heart and cardiovascular system. If you have high bp, abnormal heart rhythm, hypertension etc, DO NOT TAKE THIS MEDICATION. Also if you have anxiety or panic attacks you may want to report those to your Dr before being prescribed Adipex. This medication requires a great deal of responsibility. It curbs your appetite so you can make lifestyle changes that are easier to maintain after you are off Adipex. This is Aug. 2016 and I now weigh 205 and feel great. My waist size went from a 44 to a 36. When you stop Adipex your energy level will drop, if it doesn't level off after 2 to 3 days, have your doc check your thyroid again."

"Male 35, 6'4", 299lbs. I said I was going to report my progress in a week. But I had to report this. It has been 48hrs and I'm down 4lbs. My routine started at 10am when I took the pill. Worked out for 30 minutes. Cereal for breakfast. A shake for lunch and grilled chicken breast for dinner. No juice! Instead, water with lemon slices. Lots of it. I'm experiencing the dry mouth which cause me to drink lots of water. I'm keeping the review neutral for now. Overall goal is to drop 60lbs in 2 rounds. First round 30lbs by 9/22/16. I will wean myself of the pill by taking it every other day for the second round 30lbs by 11/22/2016. I'm well on way!!!! Stay motivated guys..!! Don't quit..!!"

"Was prescribed phentermine 6 years ago it was amazing - went from 165 to 130 in about 3 months and able to keep it off, then after losing my husband to a three year cancer battle I just gave up. In last 4 years I have watched scale creep closer to and then pass 200. I have to get weight and physcial well-being back on track NOW! Just turned 53 last week-and at 5'3 / 220 lbs., I am miserable. I've set my mind to this, picked up prescript this afternoon, starting first thing tomorrow. We are going to Cancun in Jan so need to work my butt off w/help of Phentermine to drop this weight (not sure I can get down to 130 that quick) keep up with my kids on our adventure! I rated it 10* because of previous results and positive thinking!!!!"

My cravings are completely gone! But, i haven't lost any weight! The energy feeling comes and goes, ive actually taken a nap once.. I'll try to keep my updates current."

"I'm 18 year old female, 5'6". I started Phentermine after talking to my doctor about how I eat everything in sight, and simply one plate isn't enough for me. I was always tired, lazy, unmotivated. The first day I took it, I didn't sleep at night just like all the reviews I read online said I wouldn't. I didn't mind though because when it was time to get up for the day, I wasn't tired at ALL which was crazy. Before Phentermine I was 225 lbs. That's the heaviest I've ever been. Now I'm 190 and dropping. As long as you take it about 30-45 mins before you eat breakfast in the morning and drink water, and attempt to work out, you'll strive on this medicine. I could lose a lot more if I wanted to. It gives you the energy & motivation you need!!"

Adipex-P (phentermine): "I was on adipex in 2010. I started out at 272 lbs. I was amazed at how much weight I lost every week. I had to buy new pants, jeans..etc every week. I averaged 8-12 lbs lost per week. I lost 126lbs in just under 5 months. I was very active, exercised everyday and didn't have the craving for food. I did find that not eating lead to headaches and mood changes. You have to eat!!"

Adipex-P (phentermine): "Hello everyone. I am a 22 year old female, 5'2 and 178 pounds. Back in 2010 thru 2011 I was a workout fanatic hitting the gym at least 6 days a week and eating healthier than ever. I started at 170 pounds and went down to about 128 and had a phenomenal figure. I somehow lost all motivation in 2012 (after graduating high school) and started to slowly put the weight back on. I work full time as a manager and am also a full time student. I have been struggling with my weight ever since. Here I am 4 years later and still unable to regain the motivation it takes to lose the weight! I have zero energy and have opened gym memberships, tried fit tea, it works body wraps and even a waist trainer with no success! I just filled my prescription for adipex-p and will begin it tomorrow 08/15/2016. I'm hoping for a boost of energy and also a curbed appetite so that I can learn to manage my unhealthy relationship with food. I plan on working out 3-4 days a week for the first couple of weeks and add more work out days as my progress continues to grow. I will post an update every 2 weeks from now so look out for me! Wish me luck and goodluck to all who have struggled with their weight!"

"Ok , I am supposed to ck my weight daily,and I was shocked. I started yesterday weighing 222lbs. This morning I'm at 215lbs. This has to be fluid weight loss but I'll take it. My doctor put me on Metformin also BC I have PCOS . She said she thought it would also help with the weight loss. So far I'm super excited, have tons of energy and feel great."

"I started Phentermine 37.5mg daily on 8/3/16. My weight was 272 while at my physical with my doctor. I had been exercising and watching my diet for about 3 weeks prior to that and lost 17 pounds. This morning marks one week of taking phentermine and i weighed in at 265. I use this pill to help resist temptations, not to stop me from eating or drop caloric intake. Yes, I can tell that I am not hungry all the time but I still make myself eat something light and healthy. My goal is to lose weight, not end up in a hospital. I exercise at least four times a week in which I prefer to walk briskly. I truly believe it has made a huge difference in my outcome. I have energy throughout my day and I sleep well at night."

"Hello Everyone! I'm 25 years old. I started my weight loss journey on March 27, 2016. My staring weight was at 289 and my height is only 5"5. I knew I had to make changes in my eating habits and lifestyle. Started taking phentermine on March 27th. I had a hard time sleeping at first and of course dry mouth - which just means I need to drink plenty of water. Yes! It does curve my appetite but the point of the pill is to eat more, but more HEALTHY choices and workout. I just had a weigh in on August 3rd and I weighted 254. My goal weight is between 185-220. Next weigh in I hope to weights around 245 or less. I will keep everyone posted."

Adipex-P (phentermine): "This medication works YES...HOWEVER it has side effects not listed & if you don't workout then you're not going to see the same results as the people loosing the mass amounts of weight!!! I took this supplement/medication almost 6 years ago & I worked my hind end off the 30 days I took it I lost 17 pounds that's all I need motivation to get me started in the right direction to a healthy life I worked out five days a wk changed all my eating habits (stopped eating when I was satisfied not full, if I craved it I bought it took a bite/drink and satisfied my craving) I was the smallest and healthiest I had ever been or so I thought till 2/25/15 when I had my gallbladder removed bc the damage me & my dr believes to have been from the adipex!"

Adipex-P (phentermine): "Hello everyone, I am going to review this medication from 6 years ago because it was the first & only time I had taken it & just got prescribed again today. I had blown out my right knee in 2010 bad enough to be out of work for 7 months working as a corrections officer. I weighed in pre op at 363. I am 6'4" tall & in 4 months I lost 70+ lbs. went from 363 to 286lbs from Nov. 2010 to March 2010. In that time I injured my back had to dart pain meds & the pain was so bad that I could no longer exercise. All I did was go to work & come home & lay In bed. From 2010 to today I now weigh 449. After a long battle of immobility & depression along with pain meds, I have now made my mind up to grit my teeth and make another change. This med works."

"I started this pill on June 28, 2016 and I am 5'0 tall and was weighing in at 160lbs before I took this pill. Omg!! This pill does work, it is August 1, 2016 and I am down to 148lbs that's 12 lbs over a little of a month. I'm trying to reach my goal!! I have 28lbs to go, I had to cut out bread and wine for a while and replace it with veggies and water. Some form of exercises with this pill will do wonders!!"

"UPDATE: I started taking phentermine 37.5 mg. on July 19th weighing 177lbs, today is July 30th and I weigh 169lbs. so I'm down 8lbs. I don't take the medicine everyday sometimes I skip 1 or 2 days & I only take 1/2 a pill to cut down on the side effects plus I don't want my body becoming dependent on this because I won't be on it long. I'm happy with my loss & sure it could be more but I'm trying to do this the right way as safe as possible. Will give you another update when I reach my 1st goal of losing 20lbs."

"Started 1 week ago, was on half a pill & now on the full pill, 3.75mg. Lost 6lbs in 6 days. Lost 2lbs yesterday, putting me at 8lbs total in 1 week 7-29-16. Eating 200-450 Cal per day, walking an hour and a half total per day. I am amazed by this miracle pill. I am bipolar and everything should be heightened, but I sleep fine at night and do have some extra energy. Only sleeping for a few hours a night. Can't lose weight on my own bc of meds I'm on. SO happy and so impressed. Try this if you need to lose weight! Will update next week :)"
