For Obesity: "Awesome pill!! Follow directions & you should be good! No regrets. Wish that Medicaid was still paying for it though. It currently cost me $25 from my pharmacy. Speak to your doctor first & then if it's a go~ Go HARD!! GOOD LUCK!!"

For Weight Loss: "I'm a 43 year old male. I'd taken phentermine 13 years ago with good results. Over the last year and a half, I'd gained about 30 pounds, so I spoke to my doctor about something to control my appetite, especially since I work odd hours and tend to eat. I started 3 days ago on this round. My only side effect so far has been being a bit jittery. However, I've had more than a couple positives - I'm much more alert during the day, I haven't had to take any sleeping pills like before because I'm exhausted by bedtime, and it has curbed my appetite significantly."

Adipex-P (phentermine) for Weight Loss: "Started Adipex 9/10/18. First few days, I noticed more energetic and less hungry. The insomnia also happened. Bedtime at 4:30 a.m. and up by 7:00 a.m. Finally last night I was able to sleep through 7 hours. I am Female, S.W. 202 lbs. Height, 5’9 goal is 150. Weighed in yesterday at 197. So five pound loss in 6 days. Having no more than 1000 cal. a day. I’m having trouble with wanting the foods that would help (Fish, beans, fruit etc.) Starting to feel hunger jitters today. I am not exercising. I give an 8 rating because I haven’t taken the full three months to evaluate fully. My symptoms have been slight dry mouth, insomnia, and I have noticed a higher heart rate when I am being active. I have seen people talking about raging. I am opposite, I am positive and in a great mood since day one. I read it releases chemicals in the brain that should be positive for you, but to some it must not. Good Luck to all."

For Weight Loss: "Two weeks now on phentermine and I've dropped 12 lbs. I've also been meal prepping and limiting caloric intake to about 1000 calories a day. Lots of protein, moderate carbs and under 20gm fat a day. I'm not hungry and I have enough energy to get through the day. Started at 253 lbs and goal is 170-150. The first day was rough...really bad headache and jittery. But since then, I've been fine. Lots of water as well as soluble fiber to keep the constipation at bay. Yesterday I put on pants I haven't worn in two years. I miss sugar, but not craving it. It's also fun to be cooking again! My peers see my meal prep and think I've gone out for take out. This med is the kick start and motivation I need to keep going. I'm super excited to see what I can keep doing!!"

For Obesity: "I have been taking phentermine for one week now, it has drastically suppressed my appetite and gave me a nice boost of energy. I take the 37.5 mg and I take half when I wake up and half at lunch time. I eat low carb food and I take in about 1350 calories a day. Because I am not usually hungry I have to schedule my meal times and stick to them. The only side effect I have suffered from is dry mouth and that's only if I'm not drinking enough water. In one week so far I have lost 8.5 pounds. This is just with healthier eating. I work a sedentary job and don't exercise. This medicine, so far, has been a godsend. No more mindless snacking or feeling hungry all the time."

For Obesity: "I'm starting tomorrow. I took it before but that dr only gave me like 7 Mg's. This is 37.5mg. I'm just worried because I take prozac too and u read online that it could interact with it. I'd anybody else on an SSRI?"

For Weight Loss: "4'7" and I weighed 193lb when I asked the doctor for help, two days ago. He prescribed this and I began this morning. I'm 185lb today and while I was jittery this morning, I mowed the lawn and got stuff done. Things I might have put off. I have chosen not to eat for a few days to detox my body. I am drinking a ton of water. After the detox and initial boost to my weight loss plan, I'm reintroducing fruit to my diet -- bananas for potassium, peaches for the antioxidant vitamin C, etc. After that, I'll reintroduce salads and greens. Then legumes. My goal weight is 120lb again, because I'm 64 and would feel marvelous if I got to that level. My goal is to be more health oriented. No more gasping for breath, no more sore knees, no more inability to bend over. I'm WAYYY to young to be this old."

For Obesity: "1994: (24 yo, f, 5'7" @ 220 lbs) I tried phentermine w/ high protein/low carb diet 30 min exercise/day. In 6 months I was 130lbs. I gained it back + some in a year. 2018: (48 yo, 273 lbs=morbidly obese). Thru a local clinic I restarted phentermine (37.5 mg) w/ weekly B12 shots. I weigh in w/ the nurse once a week & get my shot. Every fourth week I meet w/ the doctor. I've lost 13 lbs. as of 9/7/18 (2 mo). For 3 weeks I was plateaued at 270 lbs. It has really curbed my appetite & reduced my cravings so my calorie intake is less. I am also eating healthier with fruits & fiber. My 6 mo goal is 50 lb loss, as I am increasing my exercise with an elliptical machine. I'll do the meds for one more month, as it is recommended for max 12 weeks. I have a bit of dry mouth & drink at least a gallon of water a day. My blood pressure was slightly elevated before the meds, but the doctor has not been concerned. As for the B12 shots, I don't know if there has been any benefit."

For Weight Loss: "I'm a 30 year old female who weighted a whopping 297 pounds. I was taking medication for some other health issues and started to gain weight over the next year I went from 230 to 270 in no time. I have type 2 diabetes, and other health problems. So I began taking phentermine in June first 3 days I lost 10 pounds which I knew was water weight. I had bad habits I had to stop like eating after 7pm and drinking milk by the gallons. Eating leftovers, eating mexican food etc. I've been on this medicine for 3 months and I'm 236lb to date. That's a whopping 61 pounds in 3 months. You can't just rely on the pill. You have to drink lots of water half your body weight in water. You have to measure out your portions I'm on a 1200 calorie diet and under a Doctors care. Every month I get checked If you stick with it and follow a low calorie low carb diet this medicine will work and its changed my life. I'm continuing my journey to get to my goal of 155-160 pounds."

For Weight Loss: "I was on this diet pill back in 2015 lost 34 pounds in just two months! It was so great and made me feel so much better about myself... Well it is expensive to keep going back to Dr to get more so I stopped them and gained all of it back. I then tried it out again in 2016 and from the first day it made me feel like awful, no energy or anything. Just felt really irritable so I stopped them before I even took them all"

Adipex-P (phentermine) for Weight Loss: "It was great at helping lose weight but once you come off of it, you'll gain it all right back unless you make serious changes to your diet. It helps give you a kick start but it's never permanent. Besides, they'll only prescribe it for up to 3 months at a time."

Lomaira (phentermine) for Weight Loss: "I started this medication 10 days ago. I’ve lost 5 lbs. I’ll weigh myself again in another 10 days. I have had virtually no side effects- just more energy, which is a good thing because I have a chronic illness that causes fatigue. But no heart palps or dry mouth! I was 191 lbs on 8/22/18 and now on 9/2 I am 186 lbs. honestly, it just makes me forget about hunger."

For Obesity: "8/31/18 SW 248lb, GW 150lb. 47 yo female 5'8". Tried everything on the block after putting on 50lbs after a radical hysterectomy. Today is day one 37.5mg...it's midnight and I'm still wide awake with a nasty headache. No issues with dry mouth because I'm slightly nauseated, so hyper-salivating. Praying this works. Time for some melatonin and see if I can get some sleep."

For Weight Loss: "First day cannot sleep I’m so hoping I can sleep tonight and this part wears off. Jittery my head shaking more than usual. Weight 3 pound less and that’s obviously water weight I’ve only 16 pound to lose and this works unlike some very expensive treatments I tried like saxenda weight loss injection or mysimba (Contrave in US) which cost a fortune and did nothing. It should be easy on these pink pill phentermine and hoping the insomnia and jitters go away soon I’m 52 years old and 5ft 4 and weigh 168 pounds goal is 152 pounds"

For Weight Loss: "I'll be hopefully starting this medication tomorrow! I expect successful results within this 30 day trial. I have already planned out diet, and exercise. H; 6'1 SW; 321 GW; 221 (-100 lbs.) Diet : - Mediterranean Diet - Water + Vitamin Water - NO BREADS - Minimum dairy intake Exercise: - 30/45 minute workouts 3 times a week (Starting Goal) with basic brisk walking, and cardio. I expect a strong bolt of energy, so I am going to try my best to try and be wore out by the end of the day to get a good eight hour rest. Overall, I'm excited for the results and experience ** I'll update in a month**"

For Weight Loss: "Starting weight 243 lb. Weighed in today, approximately two months later at 215 lb. I have so much more energy, and feel better about myself. I'm down two pants sizes and don't eat near as much as I did, nor do I eat out very much anymore. My goal weight is 180 lb. the only negative side effects I've experienced are some palpitations, extreme dry mouth, increased urination, and some hair loss off my head... I have thick hair so I'm not too concerned. I don't work out, but I have a crawling baby and have taken on a second job."

Adipex-P (phentermine) for Weight Loss: "I am a 48 year old female when have been battling weight issues for over 10 years. I stopped smoking cigarettes 3/3/13 and my weight took a jump up for the worst. I lost my will power after gaining so much weight. I began to stay in the house and withdraw from social events because of being ashamed. I began taking adipex 8/15/18 weighting 234lbs. As of 8/22/18 I weigh 227lbs. THAT'S 7LBS IN 7 DAYS! Today, 8/26/18, I haven't weighed myself but I'm sure I've lost more. I have no appetite or cravings. Now that I see results, there is no turning back. Just wait until I as exercise, oh boy! Side effects are slight headaches, jittery, sweating and loose stools. The jitteriness give me energy so I don't mind."

For Obesity: "Female 24 5'6. I started taking this medication about 3 months ago I started at 232 lbs. You need to exercise and make healthier eating habits that's the only way you will see dramatic results. I'm now down to 181.4 lbs of as today. If you can't exercise all that much I suggest taking a walk in the morning and night for around 10-20 mins at least. This medication gives you horrible dry mouth but I guess that's good because you will increase your water intake, never quenched my thirst by the way. With dedication and self control you will see a lot of improvement. I lost weight to quickly and now have some loose skin around the arms inner thighs and stomachs area but found that Palmer firming cocoa butter has helped quite a bit plus it's only like 5 bucks at Wal-Mart and you smell like chocolate. Good luck"

For Weight Loss: "I started 37.5Mg on 7/2/18. I weighed 217lbs, I am 5'4" and just turned 57 years old. Today is 8/18/18 and I weigh 212 pounds. I am very discouraged... I also changed my diet to exclude all meat and my diet consists of mainly tofu and mushrooms ...salads..hummus. I do have a sweet tooth but keep my total calories between 1000 and 1200 a day. I have noticed that I get hungry very late at night so I started dividing my food up so that I could eat a little in the evening and not go over my calories. I am due to see my doctor on Oct 2nd which is three months after beginning the pill and will go from there. I will continue with the phentermine until that time and will give another update then. I had such high hopes after reading the reviews. Guess for me there is no magic pill and this will be a marathon not a sprint."
