Qsymia (phentermine / topiramate): “I am a 58 yr old female. 173 lbs ,4ft 8. Today is my first day on the med. I had a little numbness in my hands. But subside in no time. I'm not hungry. Tried to eat a half of a sandwich and took 2 bites and wasn't hungry. We celebrate mother's day tonight at my daughters with her family. Will order pizza from our favorite place, will see what happens. I'm drinking splash flavored water. Good luck every one. Go to dr on 5/28/21. Will let you know what happens.”

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): “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): “I am 48 year old female started on 7.5 mg Qsymia. My starting weight was 238lb and six days later my weight was 221.lb The first couple of days I had very low energy and felt a little groggy but I had to learn to force myself to eat because I don’t have an appetite. I do have slight blurred vision at times. I feel like it’s worth it for the weight loss. I have dry mouth as well. I have done absolutely no exercise at all but plan to start.”

Qsymia (phentermine / topiramate): “I'm done! Qsymia has helped me reach my goal! Started Sept. 2013, 52 yo female with 3 kids, 5'4" weighed 198 lbs. Now I am 145 lbs, look and feel great. With the help of Qsymia I have learned how to control my calorie intake yet still feel full and be able to eat everything I like - just the healthy versions. I hope I will be able to maintain this without taking the medication anymore...We'll see!”

Qsymia (phentermine / topiramate): “39 year old female, 65 pounds overweight. Had been exercising intensely (700 calories per day, 1.5 - 2 hours per day in the gym, part cardio, part strength) and monitoring calories under the guidance of a trainer for 6 months. Lost only 3 pounds. Was at the highest weight of my life and completely frustrated. Started Qsymia and lost 45 pounds in 5 months. Kept walking/exercising but not as intensely (about 30 - 45 minutes per day) and of course maintained a reduced calorie diet. Overall, it was an extremely positive experience and I am now about to get to my goal weight. I will stay on this for as long as it is on the market. It gave me my body back, my confidence, and my health.”

Qsymia (phentermine / topiramate): “I have been on Qsymia now since last May of last year, it is now July. I have now lost a total of 62 pounds. I have always been a bit heavy hovering around 185/190lb but ballooned to about 252lb due to my Thyroid issues getting out of control. The biggest side effects for me have been brain fog, and sleeplessness. I read an article that said they are testing the drug for use on other addictive behaviors as well. I have a lot of energy. Some people have reported mood swings, but I have always been moody so I cannot comment on this. Some days I forget to take my meds and I've been on the drug so long I do not find myself hungry or even thinking about food. The drug made food with sugar taste bad which means I rarely reach for anything sweet now or that is carb heavy. I find myself interested mostly in protein or salty foods when I do decide to finally eat.”

Qsymia (phentermine / topiramate): “Started back in June, and at first it seemed as though I was having all of the side effects from constipation to acid reflux, you name it. So far I have gone from 212 to 182 lbs. This is the only diet medication that has worked for me. It has always been a problem losing after being diagnosed with a thyroid condition. I am grateful my physician decided to try me on Qsymia. ”

Qsymia (phentermine / topiramate): “This medication changed my life! It gave me my life back. Lost 67lbs in 5months. It made the food I was eating taste like it was "crap, disgusting, processed garbage" I was a fast food Pepsi addict (case of Pepsi a day). After my first dose I have never been able to drink a Pepsi again! I craved fresh foods vegetables grass fed beef. Partnered with real kickboxing the weight came off so fast and I've been off the Qsymia for 2 months and NO weight gain just more loss. I still have no desire to eat the garbage I did before. My brother is having the same success as I have had on Qsymia. Some people say its the cost of the medication they can't do it.”

Qsymia (phentermine / topiramate): “I've only taken Qsymia a couple of days, but already I've lost several pounds and my desire for food, alcohol, and sugar. Today is day three and I do feel a little depressed today, but I want to take it a while longer to see if the depression will lift. I'll add more info as time progresses. ”

Qsymia (phentermine / topiramate): “My wife and I both started Qsymia 11 months ago and have both lost 65lbs ea. We have had no side effects other than minor tingling. We both support each other and eat normal foods just less of them. I am a diabetic and was using insulin and pills, I no longer use insulin and may be able to get off the pills soon. Our Doctor sees us every 3 months to check on us. This medicine has been good for us. But you have to work at it, it's not magic.”

Qsymia (phentermine / topiramate): “I gave Qsymia multiple chances as it seemed to work on the outset. In January 2017, I started on the trial, gradually moved up to the maximum dosage. I then had to stop due to the expense. I lost 20 lbs in 8 weeks. I gained lost weight back. In April 2019, I started again on the drug, this time at full strength. I lost about 30 lbs in 8 weeks. However, being on antidepressants (citalopram/Celexa) for depression, I believe Qsymia caused me to have suicidal thoughts and actions. I discontinued the medicine in July 2019 because of these suicidal thoughts. I was prescribed a new antidepressant (fluoxetine/Prozac) which boosted my mood considerably for a few months afterward. I gained all weight lost back. In April 2020, I tried Qsymia one last time as my weight was back up. Still on fluoxetine, within 3 weeks, my depression worsened and the suicidal thoughts came back. After stopping the medicine for two days, the thoughts seemed to dissipate.”

Qsymia (phentermine / topiramate): “I began Qsymia on June 23 and have lost 11 lbs in 3 weeks. I have experienced side effects such as pins/needles in my hands and insomnia at night if I take it too late in the day, along with dry mouth. However, the medication has allowed me to reduce my appetite, not crave food and make most foods taste bland. I have found myself on several occasions spitting food out because the taste is not there. I started at 180 and am currently at 169. I believe I could have actually done better, but I do force myself to eat some days. It is a relief to not have a bottomless pit for a stomach. I go through the website and pay approximately $98/monthly.”

Qsymia (phentermine / topiramate): “It started off slowly and at one point I thought it was doing nothing but a couple of week’s I could feel and see the change. Hunger became minimal and from there the pounds literally in my case fell off. I started out at 262lbs and I’m down to 209.4lbs in 3 months (yes 3 months). The weight loss is not just because of Qsymia but it definitely helped, I also rode my peloton (exercise) pretty much every day and also stayed away from white carbs. So would I recommend Qsymia as part of diet/weight loss plan absolutely, it definitely helps it takes away the hunger in between in meals.”

Qsymia (phentermine / topiramate): “59 yr old female 5'6 195lbs. Been taking Qsymia for 10 weeks down 26 lbs. Feel fantastic! Minimal side effects. Kicked a long standing diet coke habit due to the metallic taste. Making healthy choices and very satisfying to work at weight loss and see progress. This has been a wonderful experience!”

“I am 38 years old and 5'7". I started out at 267lb and lost 20 lbs on my own in 6 months. I hit a wall and couldn't lose any more. I tried exercise and ate a healthy diet. I went to my doctor and ask what else could I do. She recommended phentermine 37.5 mg. I tried that for a month. I lost 7 pounds. The only side effect I had on phentermine was dry mouth. I was nervous about being on phentermine because I never been one a controlled substance medication before. So after one month on phentermine, my doctor recommended that I be put on topamax 50mg twice a day. I agreed and it's been 4 days. I have lost 8 more pounds. I have more side effects with topamax than the phentermine. I have tingling in my face and fingers, extreme thirst, dizziness, weakness and constipation and some memory effects like forgetting things. I will definitely add to my review as my weight loss journey continues.”

Qsymia (phentermine / topiramate): “I've been taking Qsymia for 19 days and lost 11 pounds so far! I'm a 27 y/o female, starting weight was 289lb. After having thyroid cancer, multiple surgeries, & medication adjustments I had gained 40 pounds in 2 years and it seemed like the gaining was never ending. The first couple of days I had a constant but dull headache which stopped after 3 days. Within the first week as many others noted, soda started to taste flat and like metal so I stopped drinking it. No other changes in taste though. The main concern for me is the taste of the actual pill. I gag so bad each morning when I take it. The smell and the taste is absolutely horrible, but it's doing it's job. I still eat whatever I want, but I am at the point now where I'm eating smaller sized meals as I can't finish my food anymore. Once I eat my first meal of the day, I'm normally not hungry again until that night. I used to be able to eat all the time and snack a lot and now I'm averaging two meals a day and 1-2 snacks.”

Not so big girl · Taken for 6 months to 1 year March 2, 2017

Qsymia (phentermine / topiramate): “I took this back in 2012. I was 270 pounds when I started and lost 120 pounds in 9 months with diet and exercise In 2015 I got pregnant and gained 30 back. My doctor prescribed it again and I lost it again. It may not be for everyone but it worked for me. I was also able to maintain a healthy weight after again with diet and exercise. If your prob to being over weight you will always have to try. Don't look at it as getting thin.. look at it as a lifestyle change for your health. Diets fail but lifestyle changes last if you want them too.”

Qsymia (phentermine / topiramate): “The MIRACLE pill! I can't thank my doctor enough. I've tried every diet you can think of. Could never lose weight, I've always been obese. I started taking Qsymia on September 30/14 and lost 5lbs already. I feel with lots and lots of energy and my weakness (bread, sweets) gone! I'm not following any diet. Just exercising at least 30 minutes a day. Only side effect dry mouth and tingling in my fingers but I completely love it.”

Qsymia (phentermine / topiramate): “I began taking Qsymia in January of this year and have lost 82 pounds. The first 2 months were plagued by very intense side effects; almost every single one that the medication lists. I experienced irrational mood swings, irritability, anger, depression, tingling/numbness in my hands and feet, issues with vision (very mild), back pain (which improved with an increase of water intake), intense insomnia (which my endocrinologist ended up putting me on Ambien to aid with), cotton mouth/change of taste, and constipation (in the later months of taking it). The cost of Qsymia is a negative and so are the multiple side effects, but after leveling off after a month or so of experiencing them and following a low carb diet, it has been worth it!”

Qsymia (phentermine / topiramate): “Qsymia makes me think like a thin person. I no longer have any compulsion to find think about food. I have been obese for 98% of my adult life (I am 64) and tried everything. With Qsymia, I can make all the right decisions (and a few wrong ones) that I have known all along I needed to make. Now, just like a thin person, I am not driven to every fast food door, seconds or thirds of meals, eating a whole container or bag of anything. With minimal effort and smart decisions, I have gone from obese to within 5 pounds of normal weight for my height. No noteable side efffects - a little constipation when I don't eat much and a dry mouth. If I forget to take Qsymia for a day or two I know right away - my old eating habits come right back”

Qsymia (phentermine / topiramate): “Ive been on Qysmia now since July 2018 for about 7 months. I was prescribed the medication by my endocrinologist after a year of haywire thyroid problems. After being on Qysmia coupled with my daily thyroid meds I have lost 55 pounds!! The biggest side effects have been dry mouth, thirst, and constipation. Insurance pays for the Qsymia medication. If you can't get your insurance to do that, have your doctor prescribe it as the two separate meds phentamine and topmirate which separately are covered. Sugar does taste really bad like sand. I've had no heart or blood pressure issues. I also have a lot of energy. Also I read that they are doing research into this drug for use on other addictive behaviors other than just eating. One study said they were testing Qsymia on Alcoholics. It took away their desire to drink alcohol.”

Qsymia (phentermine / topiramate): “I've been taking Qsymia for 6 days now, and I feel the random tingling feeling and numbness, with that being said, I've lost about 4 pounds so far without changes to my lifestyle. Foods do taste different. Sodas taste like metal, rice and bread taste like cardboard, and anything other than a salad, lean grilled, broiled or steamed meats or fruits taste rather nasty. One thing is for sure, AVOID ANY DRINK WITH ASPARTAME IN IT, it will give you a monster headache and really make the tingling numb feeling really noticeable. I thought I was going to die...my head and my eyes hurt so bad. Dropped the sparkling flavored water, and diet sodas, and feeling awesome. Will update in a few weeks with progress!”

Qsymia (phentermine / topiramate): “To make a long story short. I was exalted with this weight loss journey on my own. After being fed up and knowing that I was in the season of Fall with Thanksgiving 3 weeks away, I needed a solution. Therefore, I took it upon myself on 11/04/14 at my appointment with my Endocrinologist to request a pharmaceutical pill that would aide my weight loss and BMI of 40. He gave me two options and I went with Qsymia. Thank God it was a free two week trial! Four days later, I can say I am 10 lbs lighter. Ladies and gentlemen, please do understand results may vary.”
