Reviews for Phentermine

Sort by:

For Obesity: "I started Phentermine 37.5 on 5/27/15. I did cut my intake tremendously thanks to the phentermine. I will be honest my physical activity could have been a lot more I worked out only periodically(hardly ever). As of 6/25/15 I had lost 13lbs. I started at 302 5'8 now I'm 289. This has really motivated me to work harder during the second month of my prescription. If these pills could help me lose 13 lbs with hardly any physical activity what could they do if I got off my butt! Feeling really excited and optimistic."

For Weight Loss: "I started Phentermine 37.5 on May 29, 2015 (a month now). I was at 211 (my biggest I've ever been). I already eat pretty healthy and exercise everyday for about 2 hours but I was not losing any weight. I had a friend that was on it and lost about 50 pounds so I thought I would give it a go. I got a small headache like one or two times, I still sleep really well. I went from 2011 to currently 196, a total of 15 pounds in one month. I'm hoping to lose about 50 pounds so I could get at a good weight. I bike ride everyday and run but since I'm starting my second month of dosage I am going to work on ab workouts and lifting so I can try to get toned. I'll make an update soon!"

For Weight Loss: "I was on this med for 6 weeks.I had to stop due to insomnia.It was a hard decision to stop but in the end the lack of sleep was to much to handle and affected my mood.I lost 22 pounds in those 6 weeks.Unfortunately my cravings for sweets are returning.That was the best part of this medication for me....it wasn't just the reduction in appetite."

For Obesity: "Update started 5-18-2015 @274lb ten days later I was at 261 lb. This was by exercising eating a lil better also taking water pills and a B12 shot. On 6-15 I was @ 257lb exercising slowed down my eating habits keep improving but I am trying to work out more.Yes I do the B12 also I don't get too much of a rush of phentermine really (37.5 btw) I work at 4am so the B12 really helps. I have noticed though if I take the pill and forget to eat or don't wait 30mins I don't feel it as much. I do half pill first thing in the AM and the other half around 1. So far I love this pill my weight is a constant struggle and this gives me hope . I am 25 f 5'7 would love to read more ppls reviews coming to this blog is a big motivator for me.I pay $85 for this and $20 for the B-12"

For Weight Loss: "Started adipex 15mg once per day on 6/8/15, starting weight 214lbs. Weigh in on 6/22/15 was 203lbs. I'm satisfied with this medicine & I will continue to take it until I reach my weight goal. My dr advised me that I need to take it everyday for 3 weeks & then take a week off so that I don't become intolerant of it. Side effects are minimal. Really thirsty & sometimes I dnt sleep too good."

Adipex-P (phentermine) for Obesity: "I started taking adipex 37.5 on 6/23/15. My starting weight was 301. As of 06/25/15 I was at 291! Wow! I am very impressed because I have done NO exercise at all. On the other hand, I have NO desire to eat throughout the day. I eat fruit before I take it and drink plenty of water (helps with the dry mouth too), but today (06/26/15) I am not feeling like myself. I was very jittery and weak. I realized that for the past 4 days I've only eaten 2 bags of chips, 2 bananas, and some grilled chicken. I ate something today and immediately starting feeling better. I think I'm going to try to force myself to eat more because my body is not reacting well."

For Weight Loss: "I took phentermine in 2002 on and off and lost a lot of weight. I started again on Tuesday 24 June. I currently weigh 195lbs and am 5ft 7. I wanted to ask people this forum who have had a good weightloss if they took the tablet or capsule and also if they have changed their eating habits and if they count calories? When I took it years ago I don't recall eating a lot, but now I was told I need to eat 1200 calories in order for it to work successfully. Is this correct? Thanks in advance for reading and responding."

For Weight Loss: "I started on this pill on June 12 2015 my weight was 213 I'm 5"7 well as of today I am 195 so about 18 pounds in two weeks..... I'm super happy.... but scared I will hit a wall... I am a gardener.... and always in the garden.... I am never hungry! I have to force myself to eat.... it will make me feel dizzy standing up to fast... and then I know I have to eat something... it's got to the point where almost every other day I eat only an apple.... and on the other days I eat 2 eggs with spinach in the morning..... my mouth is always dry! I have to stay hydrated working in my garden, or I will pass smooth out! But I highly recommend this diet pill!"

For Weight Loss: "Started phentermine a week ago. The first day I literally felt crazy. I was hot, sweaty and extremely active, water was my best friend! Now I just feel energized, not crazy lol. I don't have an appetite at all and if I go without water I get headaches (shocker). I take it everyday with the exception of Sunday's, I know I won't drink alot of water but I still maintain my eating habits. I've been on if for a week now and I started at 189 and today I weighed 181, so 8lbs today. I think it's great, best decision I've made so far, gonna give another update in a month."

For Weight Loss: "Hello! I started Phentermine on 6/15/15. I am 28 years old, 5'5 and 200lbs. I have been taking it around 9-10 am. First two nights I did not sleep very good at all. Today is 6/18 and will be day 4, and I've lost 4 pounds. I slept better last night with help of a sleep aid. I have not noticed many side affects. I don't feel an increase in energy (not sure if it takes awhile), have not had any headaches or the shakes. I'm not counting my calories, but I am watching my portions, not eating a big meal before bed (even if it's technically our dinner), and cut out a lot of junk. I have already cut out fast food, soda pop, and Starbucks "

For Weight Loss: "I have experienced mild to moderate headaches relatively everyday, dry mouth, bad taste in my mouth after I have taken it, severe leg cramps and a loss of 28lbs in 3 months. To off set the headaches and cramps I have increased my H2O intake to equal 1/2 of my body weight in oz. Yes, it is a struggle to drink that much however the long term benefits out weigh the temporary issues."

For Weight Loss: "I started taking phenyermine 15 mg on 6/5/2015 for 3 days then I was increased to 30mg. I started out weighing 197lbs, as of today 6/14/2015 My weight is 186lbs. I couldn't believe I had loss 11lbs in 9 days. The only problems I experienced were dry mouth ( drink plenty of water ) and insomnia. The insomnia was bad, so I started taking the medicine earlier. I was able to sleep better. I will be on this medicine for 4 months, let's see what happens. Will keep you posted. P.S. I realized that I'm constipated as well."

Adipex-P (phentermine) for Weight Loss: "My wife started taking Adipex in December of 2014, she finished it up through April 2015 and went from 187 lbs to 152 lbs. She kept to the same 1200 calorie diet she has always done for almost two years, and she works out on a variety of fitness classes to running an hour on a treadmill 3-4 times a week. It is 6/14/15 and I weigh 288 lbs and I am 5'10". I work out 4-5 times a week doing exercises like basketball twice a week for two hours and running two other times a week and lifting twice a week. So I am at the gym 5-6 times a week. Now that it is summer I plan on working out for an hour in the morning 3 times a week of cardio and lift at night."

For Obesity: "After experiencing extreme weight gain due to a horrible experience with an imbedded IUD, I was advised by a colleague to try adipex 37.5. I have been taking it since June 1, 2015 and started at 238.2 lbs. Today I weigh 227.4 lbs. it has helped me by suppressing my appetite, increasing my energy and giving me motivation by seeing my weight loss occur so quickly. I walk twice per day and lift weights three times per week. (Arms, legs, abs) I had the dry mouth but lots of water and Biotene help. Insomnia is managed by taking pill no later than 1pm. No rapid heart beat & managing salt intake may help BP. I stay below 1500 mls daily. Will update next month. I'm happy."
