For Weight Loss: "I'm a 5 foot 3, 165 pound female in her forties. Today is 5/21/17 and I'm starting on Phentermine 37.5mg; I'm only doing a half of a pill each day but if I don't see good results, will increase to a whole pill. I'm hoping to lose 45 lbs. in the next 3 months to reach my goal of 120 pounds. I have a medium frame & large breasts so I hope by losing weight, inches will fall off in my chest area as well as my waist, hips, thighs & arms. I'm exercising 5 days a week by doing PIYO & weight training. I just turned 48 two weeks ago & would like to get fit and healthy before menopause starts. SORRY for the long entry,; I will update with my results in a few weeks."

For Weight Loss: "I'm 44 years old and only 5 feet tall and have struggled with my weight for over a decade. I'm currently at my heaviest at 250 pounds. I was so small in high school - college 100 pounds. A friend at work lost 31 pounds on it in just 3 months. I asked him how he did it and he told me about it. I went to his doctor since my doc NEVER told me about this miracle of a pill and I just started it today. I've read a lot of great comments about it. I do have borderline blood pressure to start with so was told to check my bp on it daily. I took one full 37.5 pill at 10 a.m. I about 2 -3 hours later I felt a little dizzy. Around 7 pm I've had stomach upset. I'm praying I loose weight on this."

For Weight Loss: "I started Adipex-p on May 10 weighing 292 pounds. It's now May 19 and so far I've lost 9 pounds! I definitely feel like I have more energy and I have more of an endurance when doing cardio. It seems like I'll drop a couple of pounds and then stay level for a couple of days and drop again. So far my only side effect is dry mouth so I'm thirsty all the time. Can't wait to see what the rest of the month brings! 5'6" 5/9/17 292 5/19/17 283"

For Weight Loss: "So I been on this pill for a week and lost 5lbs(188 to 183). I notice I eat less due to the pill suppressing my appetite and I drink plenty of water due to the dry mouth side effect. I do get a burst of energy when I take the pill and no other side effects beside dry mouth. First week no exercise just watching what I eat now second week I started doing 30 mins cardio 3x a week. Will updated in another week."

For Obesity: "MARIE501 I wanted to share my first day on Phentermine. I weighed myself this morning at 225.8. I am a diabetic Type 2 and my A1C levels are 13.3! Yikes. I tried the Low Carb High Fat diet and it worked. I lost 8 lbs in week, but it was extremely difficult to continue. How I feel: This morning after taking pill, I could barely eat! I feel weak, but also energized (weird). I am having dry mouth, but not severe, and blurred vision. Im extremely excited to see how this works for me. Hopefully the diet treats me well. Tips: Make sure you start on like a Thursday or Friday or weekend, that way you can experience the symptoms at home rather than work. CW : 225 1 GW : 200 2 GW: 155 I will update you guys next Friday"

Adipex-P (phentermine) for Obesity: "I have tried everything I could to lose weight from pills, to shakes, to teas, to detoxing, to even a lap band, and NONE of it worked. I had hit my all-time high of 230. I went to my fertility doctor and she said I was in bad health to try to have a baby. My cholesterol was high, my blood pressure was high, and to make it worse, I was pre-diabetic. I've been on adipex now for a month and a half. I've lost 35 lbs, barely exercise, but I'm so full of energy that I've completely redone my house, cleaned the garage, and refurbished lots of furniture pieces. I LOVE IT!!! I've not had his much energy since I was in my 20s! I do have about 20 more lbs to go and it will be off in no time."

For Weight Loss: "I started Phentermine 37.5 on 04/17/2017. My weight at home the doctor office, I was 232lbs. I am 5"2'. I only took a half of a pill the first week to get my body use to the side effects. Side effects I have so far is dry mouth and increased energy level in the mornings, and itching all over my body. The doctor said I may experience constipation. I poo every other day which is normal for me. My Monday-Friday schedule is really strict. I eat 1200-1300 calories each day, drink at least a half a gallon of water, and walk for at least a mile. On the weekends, I do go over my calorie intake but I don't overdo it. As of 05/15/2017, I weighed 224lbs. Not great, in my opinion. My next appointment is 5/20/17 so hopefully I have lost more."

Adipex-P (phentermine) for Obesity: "I originally weighed 374 pounds, and I got all the way down to 304 on my own by excercising. Unfortunately, my weight picked up and I hovered at 320 for years. I became so tired and desperate, I called the doctor fearing weight gain. She put me on Adipex in March, I lost 27 pounds the first month, 12 pounds the next month, I'm still working on my third month for final tally. I am down to 287. Although there were some side effects, the health benefits far outweighed the risks for me. My blood pressure dropped 40 points in the first month alone and I am no longer pre-hypertension. This medicine has been a clean slate for me as I cook my own food and retrain my body to be nourished."

For Weight Loss: "It is May 18 I started this pill 7 days ago, my doc and I decided that I should take it because I am 310 pounds with a height of 5'9. On April 11th I had a total knee replacement so exercise right now is very limited but with this medication is great I jumped on the scale this morning and lost 9 pounds which is awesome, not really any side effects except dry mouth but that's OK because I am drinking a ton of water so that takes care of that. I love it because it takes away my hunger and my taste for sweets which is a huge thing for me. But I eat twice a day and take my pill after my breakfast and love the feeling of losing weight without much of any exercise."

For Weight Loss: "I had a total thyroidectomy last September. From the surgery until now (5/17/17) I had gained another 30lbs. Before my thyroid issues my normal weight was 130-140..I have gained roughly 70-80lbs since Feb 2016. Seen my endocrinologist last Wednesday (5/10/17) they decided to start me on phenermine. I started the pills Friday 5/12/17 starting weight 216lbs. Had to see my primary care doc today (5/17/17) and I lost 4lbs! I can't tell you how good it feels to jump on the scale and see that I lost instead of gained. Day 1 I experienced mild dizzyness, dry mouth, heart racing. I drank a lot of water and by the end of the day I felt fine. if you can stick through your body adjusting to medicine this pill will work for you!"

For Weight Loss: "I started on 37.5 mg. of phentermine yesterday, May 15. I had planned on starting with a half a pill, to see how it would be, but they are capsules prescribed by my primary physician, so I had to take a whole one. I have had no harsh side effects, thus far. I took it early in the morning and it did not disrupt my sleep last night. I did the same today. It definitely curbs my appetite and I have to make sure I remember to eat now. I am 5' 11" and weigh 200lbs. My goal is to continue with this medicine and eating healthy, along with exercise. Good luck to all who try this med."

For Obesity: "Been taking phentermine 37.5 mg since April 14 2017 since I'm morbidly obese. My weight was 258lb and I'm now 237lb thats a total of 21 lbs down within a month. I walk every evening for 45 minutes and stay away from highly sugar drinks, breads and greasy fatty foods. My goal is to lose another 40lb by August 15. First week on it I lost 8lbs then following week another 5 then went down to like 4 lbs the following two weeks. I still see it as really good. Went from a jean size 20 to a 16 now. I have been receiving weekly B12 shots for energy. Thats really helps me to staying energetic and active. Definitely a good pill for weight loss."

For Obesity: "So I'm taking phentermine 30mg. I am 5'4" 28 years old starting weight 250lb. I'm currently 220lbs. And I've been taking the pills for a month and a half. Dieting by eating 4 small healthy high protein low carb meals a day and lots of water, there are absolutely no side effects for me. Amazing energy through the whole day until bedtime. Will update at the end of my 3 month. "

For Weight Loss: "I just started this pill today. I weigh approx 196 and am 5"3". I had lost 130lbs on my own through diet and exercise, but with the loss of my son in January I have been doing a lot of emotional eating and besides that I have gained weight because I sit behind a desk all day. I am an active person which is why I didn't understand why I gained weight. I am 47 years old. I took this pill this morning and I can feel a rush of adrenaline already. I feel like I can run a marathon. My heart is not fluttering or pumping fast. I feel good so far. I took it early (7am) so we will see what the day brings. I have to say I am sad to hear some gained weight back after being off of it. My doctor did say that could happen."

For Weight Loss: "The pill has helped with my appetite. I have lost 8 pounds in about 2 weeks. But the side effects are bad. I constantly feel exhausted. I get very hot and weak if I have to do very much. It feels like my arms and legs are weighted down. It's a real struggle to do anything."

For Weight Loss: "I started out weighing 197lbs. I've fluctuated from 180-195 for the last 5 years. It's been awful. I'm 38 so shedding pounds is extremely difficult. I finally got a prescription for Phentermine and I'm down 8 lbs in just 1 week with healthy eating. No counting calories. Just tons of veggies, lean turkey burger patties, Vega protein shakes and lots of water. My goal is 130lbs since I'm only 5'2". I did decide to take a whole pill yesterday and it gave me a massive headache. Won't be doing that again."

For Weight Loss: "The first time I took it, I did manage to lose 5 pounds in a month. Unfortunately, I gained it all back after I went off it. My doctor put me on it again. I managed to lose three pounds in the first day. Unfortunately, that seems to be it. It's frustrating because although I am not hungry, my weight sometimes will go up by a pound throughout the day. I assuming this is water retention. I do walk at least 10,000 steps daily and am on my feet. I used to take Adderall for ADHD and I think that drug has ultimately destroyed my metabolism."

For Obesity: "Today is my first day. 5/11/2017. I was told me to take it around 10:00 am as it could cause insomnia if I take it in the evening. I took it at noon.I had been procrastinating all morning. I'd done research and read all of the side effects. Even after getting the RX filled and placing the pill on my napkin next to my oatmeal I was still undecided about starting this med.I'm 246lbs and 5'2. Morbidly obese. I'm tired of being fat so what the heck, let's get this party started. I swallowed hard about noon. 1:30, I was jittery and sleepy.2:30, I had to walk around to keep from laying my head on my desk. As soon as I got home, I took a nap. Where is the promised energy?"

For Weight Loss: "I started Phentermine on 04/17/2017 starting weight 236, as of 05/08/2017 my weight is 225. I am on a strict 1200-1300 calories a day diet. I work out for about 25-30mins at the gym (usually just walk about a mile a day) on my lunch break. I feel like I should be losing more. I weighed myself this morning and I'm still 225. I'm happy to have lost 11lbs so far but would love to be down more before my dr appointment on May 20. Also, I feel discouraged since I haven't lost anymore this week. "

Adipex-P (phentermine) for Obesity: "I've been on adipex for 11 months now and I've dropped 117 pounds! I didn't exercise only took the pill and cut out everything bad (even though it taste good, doesn't always make it healthy for you) eating wise. Sugar, flour, bread, pastas, FASTFOOD, and even eating after a certain time. I started eating healthy snacks every two hours, ( egg whites, cottage cheese, bag of steamers vegetables, lots of chicken, belvita snacks, carrots and peanut butter etc,and drinking lots of water! Do this and I promise you'll drop weight immediately."
