Reviews for Phentermine

Sort by:

For Weight Loss: "I am on my 45th day of taking phentermine, and I have lost 33 lbs. I had a little trouble getting to sleep the first few days, but fine now. It does give you a lot of energy which was one of my problems and does keep you feeling full. My weight when starting was 292 and I am now down to 259 in only 45 days. I am finally feeling strong enough to do the elliptical for a longer period of time. I started taking the drug to help lose weight because my doctor said I was pre-diabetic, and that was a year ago. So I fooled around for almost a year, going on and off diets and couldn't seem to stick to anything. I never liked the thought of taking pills. But I thought I would give it a try because I didn't want to get diabetes. Happy with it so far."

Adipex-P (phentermine) for Weight Loss: "I started taking adipex two weeks ago and lost 8 first week. I haven't lost anything since. I do not have more energy and in fact get tired mid day. I actually can't even tell that I am taking it. I do eat less but that is about it and have dry mouth. I found a coupon online for Kroger and it only cost me $10.88 for a 1 month supply"

I drink a fruit smoothie, I make my own on a ninja blender, lunch salad wish avocado, tomatoes, spring mix, baby spinach and kale, olive oil and vinegar.. Dinner is normally a fruit salad, chicken breast, or protein shake, whatever I feel like, but not later than 1800. I also walk 3 miles, at least 3 times a week."

For Weight Loss: "I started Phen on March 23rd and weight 193. As of June 27th, I weighed 169. My goal weight is 155. (I'm 5'10") I took a whole pill for the first couple of weeks...but, experienced extreme side effects - jitters, cotton mouth, breathing irregularities, constipation etc. I decreased my intake to 1/2 pill every morning and the side effect were more manageable. I now take the weekends off on the pill and exercise when my schedule allows. I eat extremely clean...Except for a couple of glasses of wine every now and then. I've also gotten the lipo shot 3 times since I've been in Phen."

For Weight Loss: "I started this medication a little over a month ago. I seemed to have a lot more energy at first and as of today I've lost 10 lbs. A few days ago however, I began experiencing chest tightness and shortness of breath. I went to my PCP who then sent me to the ER. I completed multiple tests and stayed overnight in the hospital for evaluation. Everything came back without any definitive answers as to the symptoms I've been experiencing. Several doctors mentioned that they believe the Phentermine to be the cause and recommended that I stop using it. It is now day 4 without taking any and I'm still feeling the same symptoms. Only time will tell... if I feel better after a week then I suppose they were correct."

For Obesity: "I started phentermine on April 5th 2016 at 253lbs, today on June 26th 2016 I am 227lbs. I made a huge diet change when I started, cut out coffees, sweets, and payed attention to my portion sizes and calorie count. I started to really notice weightloss once I joined the gym on April 18th, going to the gym made me more motivated to eat healthy and stay on track and it feels great to exercise. I had a 2 week time period during the last few months where I fell back and started drinking coffee and had fair food, ice cream, and other junk. I also didn't make time for the gym. I stopped loosing weight, I didn't gain any either though. I got myself back on track and am losing weight again. Diet and exercise definitely make this more effective."

For Weight Loss: "Hello, I'm female, 45. I am 5'3 and when I began Phentermine, I weighed 183. I asked my doctor what I could do. After 33 days on 37.5 mg, am down 15 lbs. I had been on it years ago, lost weight, gained it back. But I'll divulge this: I was not committed to weight loss my last go-round, and I was drinking very heavily. Now, I have a totally revised lifestyle: I no longer drink, and keep active, averaging a mile brisk walk daily. I get more intensive and go on hikes, vary my routine. I suspect some if the folks reviewing aren't on real Phen. This is NOT an OTC product, nor is it mail order. It's a controlled substance RX. This is not the "Fastin" from drug stores. Please don't be mislead by imitations. It works wonders if used correctly."

Adipex-P (phentermine) for Weight Loss: "I started adipex on 5-23-16 exactly 4 weeks ago from today. From the first day I took it I noticed a huge difference. I lost almost all appetite, and had to force myself to eat even though I wasn't hungry. The best thing about it is when I did eat I took the time to think about what I was putting in my body and made better and healthier choices. There are times when I wanted something I knew wasn't good for me, but my will power is stronger and I turned from it. I drink only water...It helps me stay full. I also have been working out 2-3 times a week. Only side affect I've had was dry mouth the first week. I went to the doctor today and I've lost 23lbs in 4 weeks. I recommend this to anyone struggling with weight loss."

For Weight Loss: "I have been taking Phentermine for 7 days now. Started on 6/6/16 and I feel good. Love how it suppresses my appetite, gives me energy and makes me drink plenty of water. Something I had a veey hard time doing in the past. No desire for sweets which is a great BIG plus for me. I have to remind myself to eat and try to eat healthy. The only side effect so far is dry mouth. I have noticed that I am getting cramps in places I normally don't get them. Especially in my calf area during my treadmill workouts. Not certain if this is from the drug or not? Never happened prior to. I work out 3 - 4x wk cardio. Advised by doc to stop weight training for awhile becuz it adds weight. That I miss. Am pretty bulky in arms. Concentrating in weight."

For Obesity: "I have an extreme desire for sweets, Eating in the middle of the night. I Definitely lost any desire to exercise (never been like that before)!!! I'm experiencing a dependency on this medication without it controlling my appetite. Within the first 6 months I got results but never reached my goal! Thinking I need more to reach desired weight loss!! Having difficulty with the idea of not taking it anymore even though I do not like my side effects.. Feeling sadness and then extreme happiness all in one day. I've been on this medicine for a year and two months now!!"

For Weight Loss: "Hello, I started Phentermine 37.5 on 5/19/16 as of today 6/17/16 almost a month I have lost 16lbs. My starting weight was 200lbs and I now weigh 184lbs with a goal weight of 145. I do not exercise as I should so I'm sure I would lose more if I had the time. For the first week I had dry mouth and would feel a little drunk off and on and lost 11 of the 16 lbs. As for the second and third week I did not really feel like it was working and lost 1lb the second week and 4lbs last week. Funny today I get up and take my pill like every morning and today I feel like it is the first day again, I have dry mouth, a little drunk feeling and a ton of energy, not sure if that is normal but we will see"

For Obesity: "Im 52 years old, 5'11" and weigh 284lbs!!!. I was actually 297 a month ago. My doctor prescribed Phentermine for me yesterday June 16th. I've decided not to eat after 7pm and walk vigorously at least once a day. Sweets are my "trigger" and it always makes me want something salty afterwards. I've never been this big before, not even when i was pregnant with my child. Even my feet got fat. I can't wear cute shoes and its difficult to find clothes that appeal to me. My motivation is to get the extra weight off so that I can have more energy and look the way I want to look in clothes.It's funny how much age weight puts on your face and body image. I love myself even at this size. I'm excited about this journey!!! Wish me luck!;-)"

For Weight Loss: "Started phen 1 month ago at 202 pounds. I am now 184 pounds. I have about 36 more pounds to go. I eat 1000 to 1200 calories a day and I monitor my sugar, carbs, protein, fat and nutrition. I occasionaly take a 1 or 2 day break from phen and calorie counting so when I go off phen and counting calories I know how to control myself so the weight doesn't come back. I am learning a lot about true hunger and porton control. Phen is a small part of the big picture. It is helping me set myself up for lifelong healthy eating and lifestyle habits."

Fastin (phentermine) for Weight Loss: "I used to take fastin/Fastin XR in 2012. Within a few short months, I went from a size 9/10 to a 4. I kept the weight off for 3 yrs after stopping this product. I’m only 5’3″, so all the extra weight on me was really noticeable. I didn’t like the side effects at all, shaking, racing heart…but it definitely worked. I just started taking this product again, a few days ago, because I’ve gained 35+ lbs within 4 months due to major lifestyle changes. I’m trying to get back on track again. Hopefully, I’ll get similar results this time around too."

For Weight Loss: "I am a mother of 3 with an office job and DO NOT WORKOUT WHILE TAKING THIS MEDICINE. The reason I don't workout is because it increases your heart rate to the equivalent of what it would be if you were to go for a run. I'm no cardiologist or medical expert but I don't feel like you should increase the heart rate beyond that point by actually working out. There is a certain heart rate that is unsafe based on age, height, weight.. Etc... Now that I've said that, I started taking this Medicine on Thursday June 9th 2016. I weighed in this morning June 13th 2016 and I've lost 9lbs in 4days! That's AWESOME. I'm on a no carb/low carb diet so every so often I take in some carbs it's almost impossible to avoid them. I Also drink NOTHING BUT WATER."

Today 6/12/2016 I'm weighing in at 290, I haven't really changed nothing in my diet besides not eating big portions and not eating as often like I use to. So this has been a big help for me so far."

For Weight Loss: "Update*** Started Phentermine Feb 22, 2016 at 269lbs. Last update on here was April 25th, at 247lbs. Since then I started weight watchers, which has been beneficial in keeping me on track as far as the types of foods I take in. I weighed 6/10 and I was 235. The weight loss is slow, but I still find phentemine very helpful in suppressing my appetite. A little over 30lbs in about 3.5 mos."

Adipex-P (phentermine) for Weight Loss: "I started taking this pill on 5-10-16 weighing in at 245 lbs and today is 6-12-16 and I weighed in this morning at 229 lbs. I have lost a total of 16 lbs. I take it for two weeks and stop then start again. I feel this is helping me lose weight faster. I just started exercising this week so hopefully that will help with the weight loss. I take it earlier in the day because if I don't I will be up all night. It gives me energy more than I normally have but sometimes too much where I am talking tooo much and tooo fast and I have to do something...Maybe go for a jog..Lol. So as of right now I would recommend this."
