Reviews for Phentermine

Sort by:

For Weight Loss: "I started Phentermine(37.5mg) 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 oatmeal in the morning and for lunch and supper I portion my food to about 1cup. 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 UP!"

For Weight Loss: "Today 4/8/15 is the first day I took the pill since my doctor prescribed it to me last week. I took it 30 minutes before dinner and when I went to eat I was able to eat 3 small bites before I felt like I was full and couldn't eat anymore. (My meal-baked salmon & Asian medley steamed veggies). My starting weight is 237lbs I am hoping that this works in collaboration with my personal trainer and boot camp classes. I will weigh myself on 5/8/15 to see how much I have lost. Wish me luck."

For Weight Loss: "Its been 6 weeks since I started this pill. From 150 lbs down to 135 lbs today. I'm feeling great! Back to my 5/6 shorts and pants. My self confidence was back. I would recommend this pill to those mommies out there that are having difficult time to lose weight. It was really impossible to lose weight before but today there is still a chance to get back in shape!"

For Weight Loss: "I have been on phentermine for 3 weeks now and have not lost any weight at all. It has not decreased my appetite at all, although I do eat a healthy diet for the most part. Only effects I've noticed is shakiness and a very dry mouth. I'm very disappointed because nothing else has worked and this was my last hope at losing weight."

For Weight Loss: "I am a 32 yr old mom of 3. I was at my heaviest ever! 220, I decided I needed to change and stat! My Doc started me on the lowest dose back in Dec of 2014, and as of today (4-5-2015) I am currently down to 185. My goal weight is 160. He raised me to the biggest dose of 37.5 daily. And today was my first dose and at the gym I had to cut it short because of being dizzy. I thought I was going to throw up as well. So I went to bathroom and fell on floor. I slowly walked out and drive home. I took some Tylenol and laid back down for an hour. But still 2 hours after the first feeling of this is still feel dizzy and weak. Never experienced anything like this with the other doses. Is the dose possibly too high?"

For Weight Loss: "Started phentermine by my new Dr on 4/1/15, 286 lbs. Will weigh again in a week but so far I have no food cravings lost most my appetite. Only eat 3 small meals I feel a little nauseous when I think about eating I have tons of energy but when is time for bed I can't sleep. If I knew this pill was so effective I would have started when I was 230lbs don't know why my old Dr never recommend it. I'm really excited & I Promise to keep you posted."

For Weight Loss: "Started in Jan and saw weight loss immediately! No side effects however I wasn't committed like I should have been. For example eating the wrong things, not exercising, skipping pills, etc. Now that I really know how this really works, I am committed to doing the right thing. I officially started 3-31-15 @184. Eating right, drinking plenty of water, did Zumba and on 4-2-15 weighed in and was down to 179! First goal weight is 160. Ultimate is 140. Those with side effects try taking the pill while eating first thing in the morning and drink 1 whole bottle of water with breakfast. 3 hours later eat some fruit. That helped me tremendously! And eat small every three hours even if not hungry. This will train your body once you are off!"

For Weight Loss: "I heard my friends talking about this so I thought I'd give it a try, I've been taking it for 8 weeks and lost 18 pounds. I have been working out like crazy too. THIS WILL NOT MAKE YOU LOSE WEIGHT, it's an appitite suppressent. You still have to eat right and excersise!!!"

For Obesity: "My mom and Aunts went to the doctor and got these pills to lose weight, they all lost over 20 lbs. I weigh 227lbs, its been 4 days I've been taking Phentermine 37.5. Already lost 7lbs. Its great! I have lots of energy, I just always have a dry mouth, so I make detox water with lemon, mint and strawberry/cucumber and take it with me everywhere. Lets see if I can get to my goal 170lbs."

For Weight Loss: "It works! The best "diet pill" I have ever taken. I lost 40lbs in 3 months. Exercising is the key. You have to work out to see faster results. Side effects was headaches, only because I had no appetite. Constipation was an issue, but I took care of that by juicing veggies."

For Weight Loss: "My doctor wrote out this pill for me and I lost 9 pounds the first week. After taking the pill everyday for a week I had shortness of breath and the following Monday I had a huge panic attack that landed me in the ER... The pill does work but I can't handle shortness of breath!"

For Obesity: "I have been on phentermine for 3 months exact now. When I had started I was at 294 now I am down to 253. Thats 41lbs loss so far! Its has helped me a ton as well as counting my calories and a change of diet. I have only had the dry mouth and insomnia or having a hard time sleeping on it than usual but its tolerable. Other than no complaints what so ever. I am going to continue on my weight loss journey after this month without it. This was a great boost."

For Obesity: "I started taking a half of a pill today, I ate very little. The energy is great, the only thing I am noticing is that I am not able to sleep and I am tired, also a bit of dry mouth. My goal is to loose 45lbs so I can have a surgery that I desperately need. If I can take more weight off that would be fabulous."

For Obesity: "On the recommendation of a friend I started taking Phentermine 37.5. Went to the MD on 3/30/15. I didn't want to wait to start next day so I took my first pill in the car at noon on the 30th. Starting weight 284.5lbs. Literally hunger vanished, no cravings. Woke up next day, lost 1.5 lbs. Today, 4/1, I am down 3.2 lbs and haven't even taken my 3rd pill yet. I'm going to go to the gym today to see if that boosts the effect. I'm eating very lightly. Trying to stay below 1200 Cals a day. This pill really helps with not making poor decisions. The doctor recommended drinking gulps of water between each biteful of food. And to unlearn the bad habit of eating til I'm full or cleaning the plate. He recommended using a bread plate as my guide."

For Weight Loss: "So I have always struggled with my weight, I am either trying to loose weight or gaining it....there is never an steady weight for me. I feel like I can loose weight rather quickly if I give up 100% of my mindset on it, but the downside of that is I also gain just as quickly. Now that I am in my late 30's the extra weight is now effecting my health causing high blood pressure, high cholesterol, very low self esteem, and complete misery. I love clothes, but never even want to get dressed anymore because I am uncomfortable and can't wear what I love. I am to the point that the extra weight is changing my once outgoing, bubbly personality into a shy, quiet girl because I am uncomfortable in my skin. I hope this helps! I need it badly."

For Weight Loss: "Am in UK.... PHENTERMINE is not a national health prescription drug, so I have had to get mine through a slimming and diet clinic. Started at 24 St 9 lbs.... My doctor weighs and takes my blood pressure every 2 weeks.. After 2 weeks, lost 19 lbs, after 4 weeks lost another 7lbs, after 6 weeks lost another 9lbs. Lost 2.5 stone so far and feeling great apart from constipation. I am taking favored. I also get prescribed a water tablet and a multi vitamin. I pay £84 every 4 weeks which may seem a bit steep but I feel it's worth it...."

For Obesity: "Been on phentermine 1 month, today was 1 month appointment with my doctor. I have to go in every month and show any weight loss in order to get next month prescription. I lost 23 pounds in 1 month and am thrilled. Wasn't able to exercise due to pneumonia. But plan to in month 2. Side affects were little dry mouth that water cures, and if I don't take phentermine in the morning but later I have trouble getting to sleep. The medication after first couple of days really curbs appetite and I have to really make myself eat, and because I'm not hungry I am able to take my time and make good choices on what I eat!!! Also blood pressure is way down. Looking forward to month 2, and being able to feel healthier with more weight off!!"

For Weight Loss: "First day of Adipex.. My doctor wrote me a prescription for full dose but advised me to start with half of a pill due to anxiety I may have. Took the half pill this morning and boy do I feel the energy.. Hopefully I can stay on the half strength but I've been reading reviews that say that the effects wear off after a few days. I'm a nurse so I do like the extra energy.. My starting weight is 215..ultimate goal is 165..but for now getting under 200 would be great. Hopefully I can use this extra energy to go to the gym..I'll keep everyone updated. I love reading everyone's weight loss stories.. Good to know I'm not the only one who has weight loss as an issue. Best of luck to everyone.. And stay hydrate"

For Weight Loss: "Sorry . . Continued. . Started taking phentermine 37.5 and b12 shot once a week on 02/20/15. Started @ 225lbs and size 18. By 03/20/15 I am down to a 16 and weight is 213! My weight is coming off a little slower than most Lol but I've always had to work harder for my results, the reason I started this medication. But I am very pleased because I workout and eat healthy anyway so this is only an aid for me. W/o this med I would not have lost this much so soon. On my own with a strict diet and working out everyday I only lost 8 lbs in 6 weeks. Only side effect is I'm getting bumps on my face, shoulders, back, and chest. Sometimes can't sleep @ night, and occasionally dry mouth. I can deal with those! Feeling great! Will update in 30 days!!!!!!"

Adipex-P (phentermine) for Weight Loss: "So I have always been a big girl! I have 3 kids and with each pregnancy there was added weight that just carried over and you know how the story goes...I pushed myself and my wants and needs to the side and took care of everyone but myself. The more weight I put on the more depressed I got. I got to 280lbs!!!! My body was in constant pain and discomfort and I knew I had to stop and do do something about it. I started the pills last year and lost a total of 125lbs!!! Not just the pills but I started the gym, did zumba 3 times a week and started eating good. The pills aren't the magic fix. They just help you kind of like a kick start. Sure I had side effects!!!! But nothing that would out weight being close to 300lbs."
