For Weight Loss (Obesity/Overweight) "I started taking phentermine on 07/21/15 at a starting weight of 136. I am very petite at 4'9" and wanted to go back to my usual weight of 115. Today is 08/02/15, and I am down to 127. I have been somewhat dieting and exercising once every few days. Only downside to the medication is the extreme dry mouth and it makes me very jittery the whole day. I take 1 pill every morning."

For Weight Loss (Obesity/Overweight) "I started phentermine this past week. I visited my doctor for a different issue, and she commented that she had noticed I gained some weight since the last time I had been in. I had been noticing weight gain over the past few months (some due to birth control), and I knew I had to do something about it, but just didn't know what. I exercise at least 3 times a week, sometimes 4. It just wasn't coming off. So she prescribed me this medication. So far, I have had no cravings (which is awesome for me!) and definitely decreased appetite. I started out at 174 lbs on Monday (I am 5'3), and as of today-Friday, I am 168 lbs. I hope this continues as my wedding is in 2 months! I experienced some side effects: jittery, high blood pressure, but it has gone away."

For Weight Loss (Obesity/Overweight) "I took phentermine in 2018 to lose weight after having my son. I only took a half dose for 3 days and the full dose for 3 days before I was rushed to the ER for shortness of breath, heart palpitations, and tingling pain running down my arms to my hands and legs to my feet. I was only 31 years old and previously healthy. I have been to the emergency room 6 times last year alone, multiple doctors, and medical universities since. My body has since lost the ability to control my blood pressure, which is dangerously low now. My heart rate is high and uncontrollable. I have vision problems, sexual dysfunction, cognitive problems, and so on. The doctor diagnosed me as having autonomic dysfunction, but because of more recent symptoms (vision issues in one eye, migraines, etc.), as well as psychological symptoms (rapid cycling of emotions, anger, depression, anxiety), I am going to see a neurologist to see if phen damaged my brain/nervous system."

Phentermine for Weight Loss (Obesity/Overweight) "I had a great experience using this, lost 20 lbs in the 3 months on it. Another positive, my face cleared up so, so nice!! My skin looked amazing! The first 2 weeks on it, I had terrible headaches, but they did go away eventually. The only thing I really noticed is that it triggered my anxiety a little bit and caused me to bite my nails a lot!! But other than that, I had a wonderful experience with it."

Phentermine for Weight Loss (Obesity/Overweight) "* Edit last entry, didn't include score. I've been on Lomaira for about 8 weeks and have had success. My doctor first put me on 37.5 mg generic phentermine, but I couldn't stop sweating, and it was giving me anxiety. I was definitely eating less, but I hated the feeling. My doctor told me a new weight loss medication was now available that was more targeted to evening when I tend to overeat after work. It's definitely a bit more expensive. I'm paying $29/month, and the generic was about $18/month. I prefer the brand, and I like starting on this low dose. You can go all the way up to 24 mg with this, so I will probably stay on Lomaira for a while. I've lost about 18 lbs in 2 months. I don't like drugs, so I'm happy to use less phentermine."

For Weight Loss (Obesity/Overweight) "I started the phentermine tabs after I witnessed my aunt's results. I had 2 kids within 1.5 years, gained 70 lbs with my first, lost 50 lbs, then found out I was pregnant again, gained 70 more lbs on top of the 20 lbs, so I'm up 90 lbs. I tried everything and many shakes. I went to my MD July 12th, weighed 232 lbs, had my blood work done and EKG, everything was a go, started the next morning, July 13, 2013. Today is July 17, 2013, and I'm already down to 224.8, 7.2 lbs in 4 days. I was jittery for about an hour the first day I took the pill, but it went away quickly. Dry mouth I cure with water. I love the energy, I'm not tired when I get off work. I play with my kids, watch my late-night TV shows, and wake up refreshed. Can't wait to see my 3-month results."

Phentermine for Weight Loss (Obesity/Overweight) "I made it through 3 days and discarded the bottle. I read the reviews and took the advice of most to only do a half pill. I am glad I did as the effects from just a half pill were enough to scare me. Within about 15 minutes, it felt like my heart was going to explode out of my chest. This lasted about 30 minutes, then it calmed down to a less fearful level. I felt pretty jittery and certainly like I was on 'something' for several hours. I took a 1/2 tablet twice a day, ate first to lessen the side effects. By day three, and again my heart just going nuts, and thinking how silly this will be if I have to go to the hospital, I said no more. Threw away the bottle. It will be easier to just not eat ice cream at midnight! :-)"

For Weight Loss (Obesity/Overweight) "This is so awesome reading everyone's reviews. These are real reviews to me. You read other diet ads, they are not real. I started in late August 2013. I have lost a total of 15 lbs so far! Looking to lose more. I was near the 200 lb mark. It's been like that since I had my last child in 2005. All this time I had been working out, I saw no changes. I needed a change because I have insulin resistance. That is scary to me. Diabetes runs in my family, both parents. I love this pill! It's amazing how much energy I feel. I did feel jittery when taking it at first and not feel hungry, but I ate anyway. I watch what I eat. Insomnia and dry mouth. Drink lots of water. I just want to feel better about myself."

For Weight Loss (Obesity/Overweight) "It did the trick. I lost about 30 pounds, but I was a crazy woman. Phen gave me short-term memory, a foggy mind. I got angry a lot. I felt unmotivated to study... and later down the line, I started to develop jaw pain, back pain, heart palpitations, and anxiety... all of what I listed are side effects of phen. So please listen to your body. You have to get off the phen sometime, so really concentrate on losing the weight and developing good eating habits. Do not depend on the pill as a crutch. If you do, it will surely be your downfall. It is easy to get caught up that way. For me, it's almost like a double-edged sword. I went from a size 12 jeans to 7, but almost lost my mind in the process."

For Weight Loss (Obesity/Overweight) "Best advice I can give you is to not take this pill. It was the worst medication I have ever taken. EVER. Nothing has been the same since. Lose weight the old-fashioned way. Please don't do this to yourself. It has been six months since I have stopped taking it, and I still suffer from extreme anxiety and panic attacks. I can't even go out with my family without feeling like I'm in a rush to leave. Just please don't do it. If you read this and you're feeling the same way, reach out. If you're reading this and you're just starting to take them, please be careful. All I wanted was to lose a little post-pregnancy weight, and now I suffer. I'm miserable. If I knew this would be the effects of taking this pill, I would have never taken it."

For Weight Loss (Obesity/Overweight) "I was given the medication phentermine to help lose weight due to obesity. I was taking 35 mg. This medicine packs a punch. Only take this if you are desperate to lose weight and if you can handle the side effects. Phentermine made me moody. I broke out in acne terribly. It makes you feel sick, nervous, you can feel your heart rate fluctuate so much to where it's uncomfortable and scary. From now on, I will just lose weight naturally."

For Weight Loss (Obesity/Overweight) "UPDATED REVIEW: Okay, so I started Adipex on 9/15/16, I'm 5'5" and at the time weighed 240. 16 days later (10/1/16), I'm down to 228. The side effects have subsided (insomnia, crashing, jitteriness, etc.). I find that I can go the whole day without eating due to lack of appetite, which is not good. I do have to remind myself to eat throughout the day, but that is not a big deal. I would definitely recommend this product/medication to someone who is overweight and finding it hard to lose weight on their own. So far, it seems to be working! Let's see how the next month goes!"

For Weight Loss (Obesity/Overweight) "I am a female in my early 30s who is more than 100 lbs overweight. I have suffered from severe depression my whole life, and the weight gain made me borderline suicidal. When my doctor recommended Phentermine, I was apprehensive as I have heard horror stories and was afraid it would make my depression worse. I have now been on it almost a month, and I am so glad I tried it. No additional depression or anxiety since I am on it, BUT I am on an antidepressant, so that is probably helping. Phentermine is controlling my appetite like nothing else has been able to do. I never realized how preoccupied I was with food before I tried it. I can now have pizza in my house and not think about it at all. It's like my appetite is gone."

For Weight Loss (Obesity/Overweight) "I am a large portion eater. I eat well, but I eat too much and too many carbs. I started phentermine 37.5 daily on 11/22/16. I have gone from 218 to 207. I lost 6 pounds the first week. I drank a lot of water the first week, and I haven't since, so I think that is key to the med working. I was a little jittery a few times, but it passes. Some dry mouth occasionally. Other than that, I am very pleased. Hoping to continue losing and hit my goal of 160. I am concerned as my doctor said 3 months on, then 3 months off. Time will tell, I guess."

For Weight Loss (Obesity/Overweight) "I started taking Adipex - phentermine 35.7 on August 6, 2015, weighing 195.7. I take half a pill in the morning and another half around 1. I am on my 9th day today and weighing in at 181.1. That is 14.6 lbs in 9 days. I drink a ton of water, which the dry mouth helps me with that. I follow a very strict Atkins diet and I do not miss a meal. I have not given it a 10 because I want to see what happens when I get to my weight goal and stop the medication. I was jittery for the first week, but that has passed."

For Weight Loss (Obesity/Overweight) "This is my second time using phentermine in 2 years. The first time I lost 30 pounds in 5 months, but the side effects were terrible the first time around! I would sweat just sitting down, I was jittery, dizzy, and had headaches. I gained back about 15 pounds since then and decided I'm going for it again. I was expecting the same symptoms to come back (I have the same dosage as before) but side effects this time!! I got the generic phentermine, and I like it WAY better! All it has done is decrease my appetite and give me energy. No dizziness, or getting sweaty, or feeling like you're on some crazy drug... just appetite control! I started at 254 and four days later I'm at 247!"

For Weight Loss (Obesity/Overweight) "I've only been on phentermine 37.5 since June 23, 2015. My starting weight was 220 at 5'5" and this morning I weighed in at 214.8. I take it every morning as soon as I get up with 1-2 cups of water. It does make me really thirsty (so I have been drinking more water), and the first few days, my sleep was so off and I felt really jittery. I have definitely noticed that I don't eat as much. Even if I try to eat a lot, I feel bad, so I don't try much :) I try to attend boot camp 1-3 times a week. I can't wait to see results within the next week and days to come."

For Weight Loss (Obesity/Overweight) "I'm 5'5" and I started taking this pill on 05/24, weighing 189 lbs. Today is 05/29, and I weigh 182 lbs. My goal was to lose 5 pounds a week, but I feel like I may lose more. I get jittery in the mornings after I take it and a little nauseous, but it goes away. I don't exercise. I eat once in the morning and then I have no appetite throughout the day. It does keep me up at night if I don't take it earlier than 10 a.m. And I definitely get dry mouth, which makes me crave water. I haven't started exercising yet, hopefully, I lose more then."

For Weight Loss (Obesity/Overweight) "I have been taking phentermine 37.5 mg once a day for the past 37 days. My OB-GYN prescribed it for me to take for 90 days. So far, I have lost 16.4 pounds. My highest weight was 222 lbs, which is a lot for my 5'3" frame. My goal weight is to be at 140 lbs. This has really helped jump-start my diet. I had little motivation to lose weight because I felt like it was so much! I couldn't believe how much I had put on through the years. I was constantly starting a diet and trying to eat right but not working out and getting frustrated from the results. I also have PCOS and gained a lot of weight from taking Zoloft for my anxiety. I am counting calories and working out and hopeful to see even more improvement with my remaining 53 days on the medicine."

For Weight Loss (Obesity/Overweight) "I just started taking phentermine as of 01/12/16. My weight is 191, and I am 29 years old. My goal is to lose 65 pounds! Well, for these 3 days so far, I have a lot of energy, and my cravings for food have dropped. I work in a sit-down job all day, and sometimes we're slow, and so I eat all day to keep me from boredom. I've been working out for 30 minutes because I actually have the energy to do it and watch what I eat. It is great to eat a small amount and feel satisfied. I have not been able to do this since I was a teenager. I definitely have dry mouth all day, so I carry water with me everywhere, and I'm a little jittery at times, but I feel it is worth it. I will post back in a month to report my success."

Phentermine for Weight Loss (Obesity/Overweight) "I started taking Adipex on 5/4/12. My first visit was 5/3, and I weighed in at 165.2 lbs! The first couple of days I was only taking half a pill, and I did feel a little jittery, but nothing major. The first two weeks I was on it, I did the 30 Day Shred four days a week and ate really well, but I got off track and haven't eaten healthy since or worked out. My first visit after I started, I lost 11.8 pounds. I actually weighed myself about an hour ago, and I weighed 145 lbs. Let me just say that this medicine did not give me energy, and it didn't mess with my sleep at all. It only messed up my naps, which I loved because I have a 10-month-old who doesn't sleep well at night. Just wanted to come and share my results. Hope I helped!"

For Weight Loss (Obesity/Overweight) "I started taking the pill for obesity on Nov. 28th, weighing 433, and by Dec. 18th, I weighed in at 415. Today is Dec. 28th, and I'm at 409. I'm loving this pill, feeling good, and my new scale (Ozeri Precision Pro Max). My doctor recommended the pill because of my obesity and high blood pressure. When I first started taking this pill, I had slight chest pains, as I'm only taking half of the 37.5 tablet I was prescribed. I was a lot jittery, and I had nightmares, so I stopped taking them for a week and then got back on them the next week. Now I'm fine, no chest pains, and I have a lot of energy when I'm active and at the gym, but my energy is low when I take them and don't work out. Overall, I'm happy with the results, I'm eating better, and looking better."

Phentermine for Weight Loss (Obesity/Overweight) "I started Adipex 37.5 mg 2 days ago, weighing 266 lbs. I am 4'11", female, and the only health problems are obesity and asthma (exacerbated due to weight gain). I am down to 263 lbs (-3 lbs) in 2 days. The first day, shortly after I took the pill, I felt sort of high and jittery. Wore off in a couple of hours. I took the pill earlier in the day yesterday (which I plan to do every day moving forward) right before my workout. I had tons of energy. Didn't feel high or jittery, but maybe because I worked out shortly after taking the pill. I do have dry mouth, but not terrible. It has definitely caused decreased appetite. I didn't want to eat at all yesterday. I ate 2 small meals and a snack, and before I knew it, it was bedtime. I will be more conscious of my food intake moving forward. I'm pretty sure I ate around 800 calories yesterday. I will update after my next doctor's appointment on June 19. I don't plan to weigh in again until then."

For Weight Loss (Obesity/Overweight) "I am 5'3" and I started with the weight of 140.6 lbs. Two weeks later, now I am 131.6 pounds. When I started taking the pills, I would only drink half of the pill, and it would give me bad side effects like speeding my heartbeat, dry mouth, paranoia, and nervousness, so I skipped it one day in the first week. Then, in my second week and so on, my body got used to it. I started on January 15th, we'll see how much more weight I'll be losing by February 15th. I'm so excited, can't wait."

For Weight Loss (Obesity/Overweight) "32 y/o woman here. After having my first daughter, my weight skyrocketed from 165 lb to 185 lb, then it kept going. 203 lb was my weight on June 14th. I had my check-up this week (July 17), I had lost nearly 7 lbs. My doctor put me on it for another 3 months. I have noticed I'm thirsty all the time, never hungry. I also have had pretty bad insomnia, but it's not affecting my mental or physical state. I have not really been dieting per se, just eating way less. I don't think about food 24/7. The first day, it made me jittery like I had a few energy drinks. I also feel like I have to get up and do stuff, or else I'll go crazy. This stuff does work, but you eventually end up needing to force yourself to eat."
