Qsymia (phentermine / topiramate) "I have been taking Qsymia for a year and 4 months to help me lose weight. I lost 70 lbs . I feel great. I have not lost anymore in a while but I’m afraid to stop taking it . I don’t want to gain it back. I exercise and changed my diet. My metabolic dr says it’s safe to continue. I’m in the lowest dose. ( 7.5) . This drug changed my life."

Qsymia (phentermine / topiramate) "I began taking Qysmia 15mg daily on 7-9-2019, for my 1st 3 months of check-in's, I was losing about 5 pounds a month and my Dr, was not happy with that. At month 4, he moved me to 30mg, at that time I began losing 15-20 lbs a month, with moderate diet changes and exercise. At exactly the 1 year mark, my Dr stopped my prescription. I had successfully lost 115lbs. I have further lost another 15 lbs, and have maintained for my weight loss for more than 18 months now."

Qsymia (phentermine / topiramate) "I started Qysmia in Late September of 2020, so I have been on it for almost 100 days. Early on I was loosing a whole lot of weight I started off with a 1700 calorie diet, I didn't start with exercising due to my weight (325 was my starting weight). I was down to about 294 by the begining of October (so Late August to Beginning of October I lost 31 lbs) and I began elliptical training slowly for about 15 min, then 20 min all the way to 45 minutes by November, weight loss tapers off down from crazy amounts to respectable amounts I'm now down to 2-3 lbs a week average and I'm currently down to 264. I have had a great experience so far, I had to give up soda (topimax in Qysmia makes soda taste terrible, not so much a bad thing) I pretty much drink water and bubbly here and there. Side effects: I have had dry mouth and constipation but I can deal with that. I recommend it, it has been a godsend and I feel great I have gotten my energy back and I'm eating right what more can you ask for."

Qsymia (phentermine / topiramate) "I started on the lower dose on 11/4/14. My starting weight was 301. 2 weeks later I went up a dose. On 12/4/14 my weight was 261 and I am still on the 7.5mg dosage. My doctor was so shocked when she saw me. She said the average person loses 1-2lbs a week and I've managed to lose about 10lbs a week. I also told her I cut out carbs and sugars. I no longer look at food as if I have to have it. I now look at food as a necessary nutrient my body needs to live. It is the best decision I've ever made."

Qsymia (phentermine / topiramate) "I've been taking Qsymia for 3 weeks now. I started with the 2 week starter dose and bumped up to the 7.5/46 mg dose. I have not had any side effects except for dry mouth/thirst. So far, I am loving this medication. I've lost 9lbs in the 3 weeks, and I have found that I am able to stop eating and know when I am feeling full. I am able to not eat between meals and don't have any cravings for sweets. Plus as a bonus, my insurance covers the medication which is awesome!!"

Qsymia (phentermine / topiramate) "I started taking Qsymia at the lowest dose at the beginning of 2020. I lost 50lbs between February and July. In July I had a tummy tuck to remove the excess skin from my abdomen. I had to stop taking Qsymia before my surgery per my surgeon, and had gained all of the weight back. I began taking the lowest dose of Qsymia again last month and I am down 30 lbs in 30 days. This is more weight off than the last time I took this drug, but now I am exercising much more often. My starting weight was 250, and I am now 220. My advise- taper off SLOWLY. Don't quit cold turkey like I did. I am currently eating 1200-1500 calories a day focusing mainly on protein but not cutting out foods I enjoy. Drink TONS and tons of water. I drink at least 2 L a day. This drug will make you lethargic and can lead to kidney stones if you do not hydrate properly, and most of your fat is excreted through urine- so drink water!"

Qsymia (phentermine / topiramate) "At the end of April 2018 I started to take Qsymia. Within two months by the end of June 2018 I have lost more than 20 pounds. This is the best medication to lose weight I can recommend. It works really well for me. The only side effect was feeling a little bit depressed at the end of June. I went from 170 to 145 pounds and I was able to use my two pieces bathing-suit in Florida vacation :)"

Qsymia (phentermine / topiramate) "I was skeptical about the medication Qsymia, just because I don't like taking medication and phentermine gave me bad headaches in the past; I read the reviews, I researched the medication and prayed before I started; I am a 44yr old female 5' 5, 250lbs, and hippy...my doctor started me on 7.5/46, been taking for a week, mild side effects like decrease in energy on some days, tingling of the hands and feet, pop taste bad but I'm a tea drinker... I've lost 7lbs, with no exercise...thank GOD...my appetite is gone...my portions are smaller...I'm going to add exercise a couple days a week to regain my energy and more healthy eating...but this medicine is a hit, so far...give it a try! Oh it does cost out of pocket, around $110 with coupon."

Qsymia (phentermine / topiramate) "Let me start by saying I am 59 years old. Until now, I have not had a problem losing when I needed to. I am not big on diet pills so I was a little hesitant at first. The 2 week free trial helped me decide to give it a try. The first 2 weeks I lost 6 pounds. I lost a total of 45 pounds on this medicine!! and kept it off for a year!! I have recommended it and so far have had several friends go on it an loose weight with equal success. You have to cut back on food intake and exercise. I highly recommend it!!"

Qsymia (phentermine / topiramate) "So I have been taking it for a couple months now and have lost a total of 50 pounds. In the beginning the only side effects I have encountered had been dry mouth, nausea and constipation. However now on the third month both of my legs have gotten numb and stayed numb the last couple day. I have went to several doctors and they are not sure what it is from. I was wondering if anyone else encountered this problem?"

Qsymia (phentermine / topiramate) "I have been taking Qsymia for 13 months now. I am 5'7", and was 50 when I started. I weighed 304 pounds. I have lost 105 pounds so far. I cannot praise it enough. I intend to lose another 40lb or so. It has been a life saver for me. My energy is through the roof, and the benefits to my self confidence are immeasurable. My cholesterol went from 225lb down to 185lb. So, as for side effects, I do experience bouts of constipation. I try to keep myself fully hydrated which definitely helps, and occasionally use fiber supplements as needed. In the beginning there was some dry mouth, but that passed. Also, I had some occasional tingling in my fingers early on, but that has subsided as well. I know it's not for everyone, but for me, it has worked wonders. The cost has been an issue, but I think of how much I used to spend on snack foods, takeout and the like and it doesn't even compare. I am still way ahead of the game."

Qsymia (phentermine / topiramate) "I was on Qsymia two years ago and successfully lost 55lbs. I gained it all back again and I recently went back on it. Here's my story. I'm a 43yo male, initial weight is 203lbs at 5'8" tall. My doctor, because I tolerated the drug well, put me on 11.25mg immediately and within 2 weeks, I lost 14lbs. Following 2 weeks, I've just started 15mg and I've tolerated that well and lost 4 more pounds in 2 days, so things are looking up. From experience, my past side effects were: dry mouth, tingling in my hands and feet and that's about it. Every month, my doctor will ask for a weigh in, in addition to my blood pressure measurement. As long as those two elements are good, he will continue prescribing. My insurance thankfully covers this (be sure your doctor marks down for insurance purposes that you are OBESE so it's covered!) so I pay only $20.00 out of pocket. My goal is to get back to 150lbs, which I don't believe I'll have a problem doing. It's just keeping it off!"

Qsymia (phentermine / topiramate) "I had seen a story about Qsymia on the news right before seeing my doctor for the results of my physical. I was at the highest weight I had ever been 233 lbs, 43 years old and a mostly inactive lifestyle. I did some research on side effects, printed out all the information I could find and took it with me to my appointment. My doctor was hesitant because she never heard of Qsymia, but agreed to a trial 6 month run that was in July. Today I had my fifth doctor's appointment, 40 pounds lost, current weight 193, she has approved me to be on Qsymia until the goal weight is reached since she has done research and found that it okay to be on it for the long term. No dieting! Barely exercising. Appetite is decreased - HUGE SUCCESS."

Qsymia (phentermine / topiramate) "I have been using this medication for 1 month and have lost 15 lbs. I have been very fortunate and the only side effect I have experienced is a bit of a dry mouth. That has not been bothersome it has only encouraged me to drink more water. I have continued exercising 4-5 days/week. What has been a real blessing is I have not been obsessed with food and I cannot recall a time when food was a main focus of my thoughts."

Qsymia (phentermine / topiramate) "I have suffered , like my entire family, with weight problems my entire life. Unfortunately, some injuries to my lower body joints while serving as a Paratrooper made exercise difficult and painful. Once I had my hip replaced and knees fixed I worked with my Doc and he suggested Qsymia. It worked immediately. I still had to struggle a bit and the side effects were annoying, but not debilitating. So far I am down almost 70 lbs in a year and still going. Of course the Insurance company won't pay, so be prepared to do lots of shopping around. That being said, with the half person I have lost, I am back to hiking with my family in NY (two peaks in one day) from 48 -50 pants to 38-40 pants and a blood pressure that went from 150/90 to 106/70. Look, not everyone will do as well, some will do better, but this pill really worked and a bit of dry mouth, constipation and sleeplessness are a lot better than gastric bypass!"

Qsymia (phentermine / topiramate) "I started Qysmia 3.75 on 8-25-20 @ 209lbs. I’m a 40 yr female 5’0 my heaviest was 220lbs, lost 11lbs on my own and kept it off but wanted too loose more because I have diabetes in my family. I am also bipolar and a lot of the meds I take for that make me gain weight. In just 4 short weeks I’ve lost 9.3lbs & I have so much energy & feel amazing. I go to the doctor today to see about him upping my dosage to the 7.5 . I really didn’t exercise while I was on the low starter dose, it just made me not hungry, I did have slight stomach cramps. I feel better about about myself & I’m also teaching myself to eat smaller portions and eat better food choices. When I do eat food, I tend to fill up faster. At the rate I’m loosing I hope to be at my goal weight by March, I might even go for 110lbs bc I’m so short."

Qsymia (phentermine / topiramate) "I'm 5'7 and 6 weeks ago I weighed 210 lbs. I started at the low dose for two weeks and lost 8lbs, and at the middle dose I lost 17lbs more. I've had minimal side-effects: toe and finger numbness that lasts for a few minutes and some dry mouth. Certainly nothing that I would consider stopping for. I love this pill. I have no interest in food and am so rarely hungry. It is pricey- please go to their website and get the first two weeks free and $100 off every month after that. It is worth it, I think I'm saving that in food costs."

Qsymia (phentermine / topiramate) "I’ve only been on this medication for 2 weeks but have already lost 10 lb on it . With saying that after a hysterectomy and quitting smoking it has been almost impossible to lose anything so grateful for what I have lost, as far as side effects I’ve had none I actually have way more energy and a lot of people talked about being foggy headed but I think I focus better. Definitely going to keep using this"

Qsymia (phentermine / topiramate) "61 year old female, I started Qsymia, the 3.75 prescription the first week of April. Did that for two weeks then moved on to the 7.5 dosage. I started at 388 lbs and now weigh 332lb, lost 56 lbs in three months. I like it, there are side effects. Dry mouth and stuffy nose are the worst for me. I do also get occasional headaches. But it has totally taken away my appetite and my emotional eating as well as letting me control my sweet teeth. My doctor is letting me stay on it for another four months (and hopefully longer). I have been morbidly obese all my life. Had a gastric bypass 18 years ago and put most of the weight back on. This is the first time I have felt a glimmer of hope in feeling control over my eating habits. I wish everyone success in their endeavors and hope you give it a try."

Qsymia (phentermine / topiramate) "At 220 pounds and 5' 0" I was out of control with my eating. My BMI was 43. I had to do something. I tried every over the counter diet pill there was. Finally my Dr prescribed Qsymia. I have been on it since August 2014 and have lost 89 pounds. My goal is to lose a total of 110 pounds. Dry mouth and constipation are the worst side effects, but I can deal with those. I have gone from a size 22 pants to a size 12....bust size has gone from 40DD to 36C. I now know how to eat and what not to eat to keep the weight off. I will continue on Qsymia until August. 21 more pounds to go to reach my goal of 110!"

Qsymia (phentermine / topiramate) "I am 62 years old and I have been taking Qsymia for 2 months and have lost 22 pounds. Qsymia does require me to drink alot of water and has controlled alot of my "sugar" eating. I was a Diet Dr. Pepper addict and cannot stand the taste of one now. Water has totally replaced all diet drinks. I was very hesitant to start this medication for fear of side effects, but have not had any issues other than dry mouth. Because of some orthopedic issues, I am not able to participate in physical exercise--my weight is still dropping. I have also seen a definite drop in my blood pressure with this medication; therefore, requiring changes in my blood pressure medication. I hope to continue on this medication for two or three more months."

Qsymia (phentermine / topiramate) "I'm a mom with 4 kids, ranging in age from 12yrs to 18mos. I resorted to this medication after being unsuccessful at losing weight on my own by counting calories, exercising regularly 4-5 times a week, etc. So my doctor suggested giving this a try. I'm beyond pleased that I listened to her! I started out with the 2 week free trial at the lower dose of 3.75. I was happy with that, and seeing no side effects, I went on to taking the next dose of 7.5 for 3 months (12 weeks). The only side effects I had was an occasional dry mouth, which I battled by drinking more water, which is recommended with this drug anyways. I lost about 25 pounds--I went from 178 to 152. I've been off now for 2 months and have not gained back any of the weight!"

Qsymia (phentermine / topiramate) "I started Qysmia in October 2014 with the free two week starter pack lowest dosage and then moved to the next dosage level . It Immeadiately began to work. I did experience dry mouth, a very slight tingle in my fingers and confused thinking for the first month. Those side effects where all temporary and did pass. As for my appetite it has changed considerably. It is under control, I eat what I decide to eat! Im not hungry, not thinking about food & not overeating. I am 53, had not been excercising and have lost 14lbs in 2 1/2 months. However I am starting my excercise program today because I do want the full benefit of both the weight loss and to be in good physical health. My goal is to reach 127lbs by May of this year, good luck to all!!"
