For Weight Loss (Obesity/Overweight) "I started Phen on March 23rd and weighed 193. As of June 27th, I weigh 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, cottonmouth, breathing irregularities, constipation, etc. I decreased my intake to 1/2 pill every morning, and the side effects were more manageable. I now take the weekends off from 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 three times since I've been on Phen."

For Weight Loss (Obesity/Overweight) "I started taking Phentermine 37.5 on July 19, 2015. (265 pounds) On the morning of July 27, 2015, I lost 9 pounds in just one week. That's amazing to me. I start to get jittery when I forget to eat, in which I try to eat healthy foods, chicken, fish, turkey, veggies, and fruit at least 3 times a day. It's very important and helpful to drink plenty of water, also, chewing gum helps. The one side effect for me is constipation. My goal is to get to 175 and maintain it. Best of luck to us all."

For Weight Loss (Obesity/Overweight) "Ok...so I was hesitant about phentermine because I thought all pills were a scam...but I asked my Dr., who happens to be an obesity specialist, and he said that there are a lot of meds that will work, but he said phentermine is cheap, and it works...It is cheap, a 30-day supply was around 18 dollars with my insurance. My goal is 75 lbs, and before I started phentermine, I had already lost about 8 pounds....After being on it for two weeks, I have lost 10 lbs. I don't feel hungry or crave food or snacks anymore, although I do notice it tends to wear off at night, which is when I tend to eat more...I am going to ask for a slightly higher dosage to see if that helps. Side effects...I have constipation...some jitters...not really that bad."

For Weight Loss (Obesity/Overweight) "Started the phentermine medication, and you do immediately experience less interest in food! Miracle. I needed to have become more informed because although I walk frequently, I want to drink enough water. Became a very dark feeling. Stopped it after two weeks, had lost about four pounds, 5'4", 170, yet also still held on to my habit of wanting to snack while reading and relaxing. Restarted today and will hydrate way more. Tomorrow, will take half of the normal dosing. Yes, heart rate went up by about ten beats per minute. Have low blood pressure, so that didn’t matter (well, other than additional strain on the heart?) As I continue taking phentermine, may even have a bowel motion only every other day. Absolutely been consuming more fruits and veggies and meat versus fried and white. Because truly, after I’m done with the prescription, I want these habits to stick."

For Weight Loss (Obesity/Overweight) "So I started phentermine on August 16, 2017, weighing in at 201 lbs. So far, it has been about 3 weeks, and I am down 17 lbs! I am extremely happy with this product so far and will definitely keep at it and hope to reach my weight goal very soon, which is 150! The only side effects I have had so far are dry mouth and constipation."

For Weight Loss (Obesity/Overweight) "I started on phentermine 37.5 August 6th. It's been 13 days. Side effects: constipation, dry mouth. I have dry mouth anyway due to other medications. At first, I had energy, but it's decreased. Not sure if it's the heat. I eat 1300 calories a day and drink loads of water, mostly plain iced tea. So far, about 8 pounds loss. Started weight 217, now 208. I usually walk 2 miles, but due to the heat, I can't. I was hoping for a bigger loss, but I have constant back pain, which doesn't help having cage in my back. But I keep trying every day. I'm not giving up! It's a start :). My goal is 150..."

For Weight Loss (Obesity/Overweight) "I started on 8/16/15 at 223. Today I weighed in at 210. I have been exercising 3-4 days a week: walking or Zumba. The holiday weekend, I did no exercise and still lost 1 1/2 lbs. Phentermine does not keep me up, in fact, I think it makes me sleepy. Other than dry mouth and constipation, all is well. My goal was to lose 15 lbs this month. Maybe I can get down 2 more in the next few days."

For Weight Loss (Obesity/Overweight) "I started taking this medication because I was diagnosed with type II diabetes. My doctor told me if I could lose some weight I could control it better. So with changing my diet to cater to the diabetes and these pills, I started losing weight quickly. I went from 207 lbs to my current weight of 173 lbs in just a couple of months. I feel great. Yeah, you'll drink more water from having dry mouth and be a little constipated off and on, but to me it's worth the side effects because now I am a controlled diabetic and have plenty of energy to actually play with my kids! I'm sure these pills aren't for everyone, but for me, they work and are continuing to work. I look and feel great!"

For Weight Loss (Obesity/Overweight) "I've been on Phentermine for 9 weeks now and have lost 35 lbs. The biggest side effects for me have been dry mouth and constipation. The dry mouth is tolerable, it just means I drink more water. The constipation is not so fun, but for the most part, I have been able to keep a handle on it with stool softeners and laxatives a couple of times a week. I think after week 5 the weight loss began to slow down, and I had to put in more effort. I went from a 20-30 minute walk 2-3 times a week to working out in the gym 45 minutes to an hour 4+ times a week. I've slowly built up my core, and my back and knee pain has improved. With the increase in exercise, the weight has continued to fall, and I overall feel healthier. Excited to see the end results."

For Weight Loss (Obesity/Overweight) "I have been taking phentermine 30 mg for 3 weeks now, and I have already lost 16 lbs. It's great. I do not take it every day. Normally, I take it only about 5 out of the 7 days. It gives me great energy but makes me constipated! I do not exercise, I only watch what I eat... I love it."

For Weight Loss (Obesity/Overweight) "Adipex took away my hunger and cravings completely the first couple of days, but it did take some getting used to. The first day I was very groggy and confused, but it got better. Here are the side effects I experienced: hair loss, dry eyes and mouth, constipation, jitters and tremors, insomnia, forgetfulness, irritation/agitation, high blood pressure. Pros: lost 40 lbs, tons of energy, took away my headaches. I had frequent headaches before this medication. Adipex took them away like a miracle. After 3 months, it stopped working as far as a hunger reducer and cravings came back. Still had tons of energy and no headaches. The doctor kept me on, but I started getting high blood pressure. Decided to wean myself off. Now getting headaches and low energy. My weight also started to plateau the last few weeks."

For Weight Loss (Obesity/Overweight) "I started phentermine (37.5 mg) on March 30th. I started out at 246 lbs. I am now down to 230.4! This pill does work! I have barely exercised, I eat 1 package of oatmeal in the morning, and for lunch and supper, I portion my food to about 1 cup. If I am not hungry for supper or lunch, I eat fruit. Drink lots of water, very dry mouth has gotten worse since the first week. The first day I had so much energy, and it felt wonderful! My side effects, which have been iffy but I've managed, are: dry mouth, occasional headache, trouble falling asleep, anxiety, tightness in chest, panic attack (only 1 day, and it was bad), tingling in arms, constipation (that's why I eat oatmeal every morning), dizziness. But the belly is going down and self-esteem is up!"

For Weight Loss (Obesity/Overweight) "I started taking phentermine 5 days ago, and have lost 7 pounds. As several others have mentioned, I also have constipation. I think it's simply because I am eating 1/5 of what I was eating prior to taking the pill. I am sleeping fine, however, I do sleep less. I have more energy and am a bit irritable."

For Weight Loss (Obesity/Overweight) "I am a 57-year-old woman just going into menopause. I gained about 15 pounds. I could eat all day, and it seemed like I couldn't get full. I would exercise, but I overate my workouts. I would always start a diet on Monday and would stay focused until the weekend came. I was so tired of losing and gaining the same 4 pounds. I went to my doctor for my yearly checkup and explained to him my menopause weight gain. I asked for some diet pills, and he suggested phentermine. Started on October 5 at 186. At my 30-day weigh-in, I am 176. I am on my second round and will be weighing in December. The only side effects were dry mouth, slight headache, constipation, and trouble sleeping. After a week, side effects none. Goal weight 165."

For Weight Loss (Obesity/Overweight) "I started phentermine on September 15, and as of September 23, I lost 8 lbs in a week. I'm so happy. I do have some side effects, I'm always thirsty, and I get constipated. But after all, it's great. It gives me energy through the entire day. I'm less hungry. My start weight was 185 lbs, and now I'm at 177 lbs. Looking forward to losing 50 lbs more. I exercise at least 4 times a week for at least an hour."

For Weight Loss (Obesity/Overweight) "I used this in 2004 and lost 49 lbs. I was 201 lbs at 5'1', you can imagine. My doctor only prescribed it for 3 months, but I was able to 'shrink' my stomach enough to continue to lose. Works amazing with exercise. I maintained the loss until I became pregnant with my 3rd child and went up to 168 lbs. I am now 155 lbs, and my doctor just prescribed a 3-month supply again. I MUST drop the final 25 pounds, and I KNOW this will do it! Yes, I did have dry mouth and slight constipation, but I was not hungry at all! Great medicine if you want help and are willing to do some healthier eating (which will be so easy because you aren't hungry) and exercise (also easy because you'll be feeling so good about yourself). Good luck!"

For Weight Loss (Obesity/Overweight) "I started Phentermine 8 weeks ago, and I have lost 15 pounds so far with little effort. I love the medication because it gives me plenty of energy and takes away my appetite. But, like others have said, it causes a dry mouth and severe constipation. I have to take laxatives and stool softeners daily. But it's worth it. After about six weeks, I noticed that it's not working as well as it used to, and I'm not losing as much weight as I did in the beginning, but it still is controlling my appetite. The downfall for me is that it makes my heart skip a beat now and then, and I feel a little heaviness in my chest from time to time, which is scary. It is definitely caused by the Phentermine. My doctor tells me I should stop taking it now, so I will."

For Weight Loss (Obesity/Overweight) "I started that phentermine on 10/22/17. I have lost 40 pounds. My starting weight was 278 lb. I have had side effects: dry mouth, constipation, and rash, and one or two heart palpitations. I have changed my eating habits. I only do 100 carbs a day, if any. My weight loss has slowed down as of 1/01/18, not losing as much weekly. Some of my clothes went from a size 22/24 to 16/18. Understanding it's a short-term med - it is really a lifestyle change! Very helpful medicine for someone who is overweight and needs a new chance at life medically."

These are tolerable, such as dry mouth and constipation. I drink plenty of water. Also, eating plenty of veggies really helps. I do not crave any sweets or junk food. This med is great if you are overweight. Has helped with overeating and indulgence."

For Weight Loss (Obesity/Overweight) "I have been taking this medication for about 6 weeks and have lost 12 pounds, including 5 inches off my hips and 2 inches off my waist. I exercise 5 days a week. It is an intense workout, which includes cardio and weights. I do not feel as hungry all of the time like I did before. I drink a gallon of water a day, if not more. I have experienced a few side effects, like dry mouth, rapid heart rate, some constipation, and headache. I want to continue until I reach my goal and do not want to give up! Seems like in the past I always give up, but not this time. This works really well and I highly recommend this. I have 25-30 pounds more to go!"

For Weight Loss (Obesity/Overweight) "I started taking this drug prescribed by my doctor on 6/21/16. I had started a diet the previous week of only fruit and vegetables. I dropped a good 8 pounds from that. I started medication, and it has helped my appetite control. I took one full pill every day for a week. I started walking a lot. A good 2-3 miles a day. I also kept with eating fruit in the morning and low carb/protein during the rest of the day. I have had to drop down to half a pill because of insomnia and have noticed constipation. I am on Weight Watchers now and follow the plan. I eat fruit and vegetables like crazy, and I know it helps the weight loss. I am down 13 pounds as of 7/8/16. I am sure I will start to lose 1-2 pounds a week soon, which is the healthy way."

For Weight Loss (Obesity/Overweight) "I have lost 38 pounds on this since September 2013. I am on a diabetic diet and a fitness program also. This medication has helped me a lot! Taken the edge off the hunger and helped me get my glucose levels under control. There are some side effects, but many of them went away by week 3. Metal taste in my mouth, headaches, constipation (has not gone away), and dry mouth/bad breath. This is not a miracle pill. You will have to work hard and make good choices. My doctor is helping me learn how to make better choices and make healthy living a part of my life. I plan on being on this medicine ONLY until I can successfully learn how to control my glucose levels and follow a plan consistently."

For Weight Loss (Obesity/Overweight) "I started phen one week ago, after dieting and exercising for 11 weeks and only losing 10 pounds. I'm on a 37.5 mg dose. I started phen on May 14 at 179 lbs. I'm down 5 pounds! I have exercised twice. I've had serious dry mouth, headaches for a week, but yesterday, no headache. Twice I've felt mild numbing in my face and constipation. The following may be too much information - you are warned. I also started my period 4 days ago, experienced heavy bleeding for the first 2 days, like having to change my pad every hour and a half because I bled through to my clothes. I'm not sure if it has anything to do with the medication, but it's not normal for me. But it's not bad enough to make me stop taking it!"

Today, not quite 5 weeks later, I am 221. 24 lbs lost in less than 5 weeks with min exercise (20 min walk 2-3 times a week). I have noticed the weight loss slowing down a little and will begin working with a trainer 4 times a week on Monday. Negative side effects for me have been dry mouth (just means I'm drinking more water!) and constipation. Unfortunately, my provider would only like me to take the medication for 12 weeks. I know other providers who have prescribed for 6 months. I hope I can talk her into it!"

For Weight Loss (Obesity/Overweight) "This medication absolutely works. It suppresses your appetite and sweet cravings. I was an eater who would eat beyond fullness and then feel awful, but with this medication, you will tend to eat smaller portions and can easily stop after feeling satiated. I've also been getting the Vitamin B12 injections, which increases metabolism. I started phentermine 37.5 mg on July 1, 2009, weighing in at 263 lbs. Two weeks later, I weighed in at 250 lbs. My last weigh-in was July 29th, I weighed 243 lbs. I've opted to eat sugar-free snacks, which I cannot tell the difference. Also, I've been drinking diet sodas and plenty of water because side effects may include dry mouth and constipation. My doctor recommends 30 minutes of cardio exercises/activities three times a week."
