Reviews for Phentermine

Adipex-P (phentermine): “I started Adipex on 8/30/14 and as of 9/15/14 I've gone from 202 to 185lbs. 17lbs in a little over 2 weeks, I'm 5'6" and borderline diabetic. My doctor has been on me for the past 5 years to lose weight. She says I'm considered obese and will have to put me on medication for the diabetes soon, but my wake up call was when my joints started aching, and I was losing feeling in my feet. In addition to Adipex, I've eaten 85% clean, opting to snack on baby carrots instead of cheese and crackers. All I drink is water, I've cut out the alcohol, coffee and all fats and sweets. I walk everywhere and have lots of energy. I take 1 pill between 9:30 & 11am every day, and I fall asleep by 10:30pm. My goal is to be around 150lbs.”

“I’m 62 and a Veteran. I have always been active. I started slowing down a bit, and gained some weight. I’m Diabetic and have tried to loose weight. I’m 5ft 8 and weighed 240 lbs. I went on a 1200 calorie diet for 3 months and loss 10 lbs. I leveled out. Went to see my PCP for some help. He put me on Phentermine 30mgs per day . Wow , in 2 months I have lost 24 lbs and eat like a bird. I have a salad and I am full for the day. I still walk and stay busy. I am retired because I am disabled. My desire for food is almost zero. I feel much better, my blood sugar is way down. You have to drink lots of water on this medication. Dry mouth is always there. I have to keep going and I plan too. For my Family. God Bless.”

“Update, (I did a review on 2020-01-23) I have been taking phentermine now for 30 days. I started out at 316 pounds. As of this morning I weighed in at 295. I’ve lost 21lbs. I am 49 years old and 6” tall. I am surprisingly ecstatic over my results. As far as side effects I actually haven’t experienced any. The very first day I took the medication I did have mild increase in heart rate. I know that the medication will react differently with each individual. But so far mine has been non existent. I will check back and give update in another 30 days.”

“I have been on 30mg phentermine daily for about 2 years. The weight melted off the first 9 months then slowed for 6 months. The last 6 months I have have gained weight. Will be going off for a few months and then hopefully get out back on. I lost 60lbs in about a year. I love the boost in energy I feel. Does give you extreme dry mouth.”

Adipex-P (phentermine): “I usually don't give reviews but for Adipex is necessary that I share with you. I started on 3/4/14 at 215 pounds, today 4/7/14 I'm @ 198lbs. In only 33 days I've lost 17 lbs. I'm eating healthy and small portions, cause I don't get hungry.. I don't crave nor look for fast food restaurants. I've added more fruits and veggies into my menu. I'm staying away from sugar and bread. I'm thirsty all the time, water, water is my best friend. If you are reading this I was just like you 30 days ago reading and trying to find out if this would work, and my answer is "YES" it does. Just take it day by day and eat right and exercise. Will give my next update at the end of April.”

“Ok so I used both brand I’m on generic phentermine now when I used the brand I lost 15 pounds in one week, when I used the generic kind my weight loss slowed down. I also noticed when using the brand I had so much energy I mean I was moving around I was not as lazy or tired but generic made my stomach hurt a lot in use the bathroom slower process. I personally prefer the brand I don’t mind paying 60-70 a month”

Frequently asked questions

Ali4 October 18, 2013

Adipex-P (phentermine): “I am 5'5", and 31 yo. I have been overweight my whole life. Even as a child. At my heaviest I weighed 256lbs. I could hardly make it up and down the stairs. That is when I started taking Adipex. I am now 149lbs, and feel amazing! I know that there are side effects with every medicine, but there are also side effects to being overweight. Honestly, it is not easy to being weaned off. You have to work hard everyday, not to cave into the cravings, and keep active. It gave me the edge I needed to make that life change. Other friends that have tried using Adipex, but could no stick to the diet and exercise plan and lost little to no weight! You need to want to make the change, the pills just help.”

“59 year old woman, 5 foot 3 inches, 195 pounds, lifelong exerciser, problems maintaining my weight for the last 4 years. Taking 37.5 mg phentermine tablet first thing in the morning. I have lost 10 pounds in 3 weeks. I lift weights and use the ArcTrainer or treadmill/walk outside but I have always done that. Phentermine is what is helping me eat less and lose weight. Eating 1000-1200 calories/day. No side effects. If anything I think the effect is starting to wear off already.”

I weighed in at 335lbs and now 320lbs. I go back on October 26, 2018 and I will definitely let you know. I haven’t had any side effects at all! I mean none!! I do walk 5 days a week for 30 minutes, nothing else. I am very happy and I am starting to feel better about myself.”

Adipex-P (phentermine): “I have been taking this medicine for 20 days and I’ve had minimal side effects. It’s made me more irritable and the first 2 days of taking it, it made me feel a little weird. I had trouble sleeping at night for the first week and half but I think that’s been resolved. This gave me the kick start that I needed. I don’t know how much weight I’ve lost since starting it and will know when I go to my 1 month appointment. I’ve definitely been losing weight. It’s pointless to take this medicine if your not actively taking steps to eat right and exercise- something that this medicine helped me kick start. I’ve been exercising everyday and have been eating great. This took away all of my cravings and I haven’t drunk any pop since taking it- that was my biggest weakness. I will post an update as soon as I know. I started at 222lbs and I’m 5’7”

Lomaira (phentermine): “I haven't had much success with my weight loss goals over the past few years, so when my doctor recommended a new treatment, I didn't get my hopes up. I've been pleasantly surprised though! Two months in and I've lost over 20 pounds. At this rate I should be able to meet all my goals!”

Adipex-P (phentermine): “Teva, the makers of Adipex, changed the formulation of brand name Adipex in Spring 2021. My last 2 prescriptions, March and May 2021, have literally felt like I’m taking a water pill! At a price of $2.50 per pill, I won’t be refilling or paying for this medication anymore. Total waste of money. I’ve been a loyal customer, have used Adipex on and off for over 20 yrs with great success, so I know how they work. Contacted the manufacturer to no avail. Terribly disappointing.”

Adipex-P (phentermine): “Adipex 37.5 is the real deal. This is my 2nd time on adipex. The first time I lost about 80lbs in 3 months. The first 3 days I lost 12 lbs adipex is an appetite suppressant and it will for sure make you less hungry. Also monitor your blood pressure because adipex does elevate it. Try not to consume energy drinks or anything with caffeine in it. The weight will fall off pretty fast depending on your eating habits - just be patient.”

Adipex-P (phentermine): “I lost 30 pounds in less than 3 months with this drug, a sensible diet and exercise. I had started and quit a few diets before taking this medicine because I never felt satisfied after a small meal and I always wanted to snack. The first day I took it, I was shocked at my lack of interest in food. I would eat, but not with the same vigor and certainly not the same quantities. I noticed my mood was improved and that I had the energy to do things, including obsessive cleaning of my house. After several weeks of taking it, the medicine didn't seem as strong to me; however, my new eating and exercise patterns were established. Good diet starter but not a permanent solution.”

“So far this is absolutely the best aid in losing weight for me. I had lost 75 lbs in 2011 with Weight Watchers but gained about 38 lbs back between 2012 and 2014. I went to the doctor and he put me on phentermine & chromium picolinate. I have been on this since 8/23/14. In 6 wks I have lost 25 lbs. It has significantly decreased my appetite to where I don't even think about eating and have to remind myself to do so. The only side effects I have had are dry mouth, which causes me to drink water constantly (so not a bad thing), mild insomnia the first 2 wks & constipation, for which I just take a supplement. BUT you have to eat right. Reduced carbs for sure. Weight Watchers taught me healthy eating so you do have to change your food.”

“I’m a 49yr old male that has peaked at my highest weight ever 316 pounds. I went to discuss this with my PCP to find out what my options were. I’m 6”0 tall and always have been big. He suggested phentermine, I went in to his office two weeks ago and started the drug. I have lost 11lbs as of today. I have had no side effects except dry mouth. It definitely suppresses your food intake. I’m on the 37.5 and absolutely love it so far. I will keep posting updates.”

Adipex-P (phentermine): “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.”

Adipex-P (phentermine): “My starting weight was 285lbs. After a 3 months, I am 245lbs. I take 37.5mg in the morning and 15mg around 2pm. I will admit that in the beginning I was not eating as healthy as I should have been. Now I don't crave the sugar and fats that I used to. My once favorite food, Philly cheesesteaks, are only mildly appetizing to me. I have to remind myself to eat during the day. The only problem is that if I stay up too late I do start to crave junk food, carbs mostly.”

“I took phentermine for 2 months and went from 316lb to 270lb. I only had dry mouth as a side effect. After the 2 months I stopped taking it and gained back 16 more pounds. I'm back on it again possibly another 2-3 months in hopes on losing the 16+ again. However that's the worst part you can gain it back if you don't keep your weight loss under your control..I didn't and it cost me”

Adipex-P (phentermine): “I started on 8/24/15 as of today 9/6 I have lost 10 lbs, just under 2 weeks. I only take half a pill which is just fine for me. I have very little appetite, I force myself to eat. I'm staying under 1200 calories per day, more like 800. My cravings for sweets are gone! This is strange for me because I love sweets. I'm not eating any bread or drinking any soda. Lots of water, fruits, veggies, salads and protein. I have not exercised yet but plan to soon. I could not sleep the first few days and dry mouth is starting to kick in, it's tolerable. My goal is to lose 60 lbs by the end of the year.”

Adipex-P (phentermine): “I took adipex for 6 months... my starting weight was 210.0 ... ending weight was 165.0 ... that was a year ago. This is MY advice. #1. You may not FEEL like eating... but do it anyways... or you'll slow your metabolism down to a crawl and stop losing weight. Just watch what you eat!! #2. Take vitamins!!!! By the time I hit 165# - my hair was starting to fall out, I couldn't focus, and I was constantly tired - sometimes I'd nearly pass out... because "I didn't feel hungry" and just wasn't really eating more than 500 calories a day. Even sitting STILL your body burns way more than that! #3. Be prepared to gain some of that back when you come off the pill. I wasn't prepared at all - and I gained it all right back. Still, great pill!”

Adipex-P (phentermine): “I took Adipex (37.5) from February 2012-April 2012 and in that span of time I went from 300 lbs down to 170 lbs. That is a loss of 130 lbs. I hardly ate anything but grilled chicken, fruit, and powerade. I walked at least 2 miles everyday. I got Pregnant at the end May 2012 so I had to stop taking it. My baby is now 2 years and 5 months and my weight has gone back up to a very uncomfortable 240 lbs. I still exercise regularly but not as often as I should. I have an appointment in 3 weeks to get adipex again and I am hoping and praying that I have the same results as before. This is a great aid in loosing weight for anybody who struggles with loosing weight by diet alone. Wish me luck...will update in 90 days!!!”

“This drug phentermine is amazing to help loose weight! I was skeptical before trying it. I didn’t think an appetite suoppressant would help; even when I’m not hungry, I eat. I’m glad I tried it. It doesn’t just curb hunger pangs; it made me not focus on food. I used to obsess about food, and I’d keep thinking about it til I gave in. On phentermine, I go hours without feeling hungry OR thinking about food! Maybe an occasional craving but quickly forgotten. I went for my follow up and in just over 5 weeks, I have lost 22 pounds! And it was pretty painless. I did eat less; primarily veggies and lean protein with some fruit. And I exercise 5 days/week. So it wasn’t all phentermine. But it really helps. I take it in the morning so it doesn’t affect my sleep, but I noticed that I don’t take midday naps now. Definitely experienced dry mouth, and occasionally I feel anxious, but otherwise no side effects. My blood pressure has not been affected. This stuff is AMAZING.”

Adipex-P (phentermine): “I have been taking Adipex-P 37.5 mg for 8 months and I am happy to say that I have gone from a 26/28W to a size 16/18 and lost 100lbs to date. It works. But, I changed my eating habits, I eat healthy and maintain exercise. Adipex was what I needed to find motivation to get off the couch and enjoy life again. My blood pressure is down, my cholesterol is down, and I am no longer about to be a diabetic! A happy and healthier me!”
