For Weight Loss (Obesity/Overweight) "I started Qsymia in December 2016 and had the finger and toe numbness, trouble sleeping, and anxiety but that only lasted the first 10 days or so. In the past year, I've lost 50 lbs, and that's without a ton of changes. I noticed a huge change in my appetite. I wasn't someone that overate to begin with, which was why my weight was frustrating, but now I notice I have to make an effort to eat meals because I'm rarely hungry. I have plenty of energy to do everything I need to do. I am at my initial goal weight but now looking to go an extra 10 lbs lighter. If I add moderate exercise, the weight comes off quick which was impossible before Qsymia. I highly recommend this! It's tough the first 2 weeks but past that, it's been super easy for me."

For Weight Loss (Obesity/Overweight) "This medication has worked great. You must drink plenty of water! Also, start taking it on a Friday or better yet, start Thursday and take Friday and Monday off of work if possible to give your body time to adapt. My body took a few days to adapt when I first started taking Qsymia as well as between dosage changes. Though it was much less noticeable between dosage changes. For me, the side effects of blurred vision, not being able to think sharply, feeling jittery, etc., only lasted a few days. If you can take the time to get over the hump, it is totally worth it. Also, I have cut out sugary drinks, snacking, and eating after dinner. I drink 8-12 16oz bottles of water per day. I have been on Qsymia for 1 month and lost 13 lbs."

For Weight Loss (Obesity/Overweight) "I have been on Qsymia for exactly one week. I have been counting calories (consuming between 1000-1200 calories per day) and have lost 12 pounds. I have no real desire to eat. I have noticed that Diet Coke with Splenda tastes odd to me (not a diet soda drinker otherwise). I do not feel jittery & have not experienced any other side effects. I am very pleased."

For Weight Loss (Obesity/Overweight) "I was totally excited about this medicine. I had about 50 pounds to lose. I took 6 days of the beginning lower dosage and began my journey into depression, anxiety, and panic attacks. After consulting with my diabetic specialist, we both determined the side effects were not worth it. I am happy for those who have had a positive experience, but with the side effects I experienced, it was not worth it for me."

For Weight Loss (Obesity/Overweight) "This review is based on my experience and my reaction to it. I wish I had never taken this medicine. It induced horrible anxiety and panic attacks that I had under control for close to 3 years while taking an SSRI only for anxiety. If you have a history of anxiety, I would not recommend this medicine. There are other options out there, and this one should not be on the market."

For Weight Loss (Obesity/Overweight) "I have been taking Qsymia 3.75 mg since January 2, 2017, which makes today two weeks. Within those two weeks, I have lost 7 pounds. I have not completely changed my diet, but I have been eating healthier and lighter, along with exercising. The only side effect I have experienced is an increased heart rate at rest. It did give me a little anxiety at first because I never experienced anything like it before, but now it has decreased/subsided. My doctor told me that some side effects may come back or go away with a dosage increase, so I hope it doesn't now that I have started the 7.5 mg. Good luck to everyone on or wanting to try this drug!"

For Weight Loss (Obesity/Overweight) "I'm 26 years old, 5'3. A year and a half ago, I quit taking Vyvanse, I didn't like the way it made me feel, and since then, I have gained about 80 pounds in the past year. I began at 199 on 6/25/15, now I weigh 194.4 on 7/13/15, so it's only been about 2.5 weeks, and I've lost about 5 pounds. I hope to see good results with this medication because it has been very difficult for me to look in the mirror and know I let this happen, especially since I've been fit for most of my life. Beer, Coke, and Pepsi taste awful, wine still tastes good. I've had minimal side effects: tingly hands, feet, nervousness. But not very often. I hope this helps."

I got really hot and anxious. Come 9:30 p.m., my eyes and top of my head had such pressure. Not to mention I was ravenous all day."

For Weight Loss (Obesity/Overweight) "I'm always leery about primary care providers pushing weight loss meds like Belviq and Qsymia and insulin pens that make you lose weight. After all, what incentives are they getting from the company? The upside to this medicine is the trial basis took care of my cervical neck pain, but the combination of the meds was a disaster. I felt moody, irritable, anxious, depressed, hopeless, tingly all over, headaches, nauseated, thirsty, never hungry thanks to nausea, sleeplessness, wired!!! and tired!!! Odd sensations, cold and heat intolerance, panic, blurred vision. No thanks, I would rather be fat and happy! I was eating healthy and drinking only water but was unable to lose the weight. This is a horrible medicine!!"

For Weight Loss (Obesity/Overweight) "This is an update on the comment below. I was diagnosed with ADHD about 12 years ago but stopped taking my medication for it many years ago because it made me feel jittery. I have noticed, since I started Qsymia, that my ADHD is under control! With no jittery feeling, and it works better than the previous meds did. This is not used as a med for ADHD, to my knowledge, but it should be investigated. Previous comment: I started Qsymia 5 days ago and am down 3 pounds. I am able to control my portions and snacking very well and am not very hungry. This is the low dose also. I had previously been on Contrave for 2 months, which made me extremely nauseous, and I gained 8 pounds on it because I wanted to eat when I was nauseated. The only side effects I notice are insomnia and restless legs at night. Unfortunately, I am unable to exercise because I broke my patella a week ago, so that may slow down my progress some. Overall, this seems like a good medication."

For Weight Loss (Obesity/Overweight) "5'2", 160 lb, 48 y/o female - 14-day trial then moved to 7.5 mg - 30 days and so far lost 7 lbs. - overall good experience. At first had a little bit of an anxiety attack - skipped one pill and then decided that it was me being me and decided to resume taking the pills and so far so good. I had a bit of the tingling, dry mouth, but I also experienced unusual frequency urination, which for what I read is tied to the Topamax. I have a doctor's appointment and I will ask about it, it almost feels like a UTI, but I'm certain it's not an infection. I exercise 5 times a week. I've always watched my diet, but I always had issues maintaining a healthy weight (I'm one of those unlucky souls) and had a huge fibroid which was embolized last year but throwing my hormones out of whack, plus I'm probably peri-menopausal causing me 15 lbs weight gain. I plan to stop at 145 lb, however, my ideal would be 135.. thanks."

For Weight Loss (Obesity/Overweight) "Day 5 of trial dosage. I'm doing Weight Watchers too. I see no benefit in terms of appetite suppressant. I have not noticed it making food taste different. I do feel it helps a bit with cravings. It's making me jittery, causing monster headaches, and making my blood pressure spike. Not sure if it will be worth continuing. I'll continue the trial if my doctor okays it and post again in the future."

I did lose weight (about 10 lbs), which continued even 2 months after (now 15 lbs). Two months later, I am having horrible stomach issues (going to a specialist to rule out IBS or something else)."

For Weight Loss (Obesity/Overweight) "Gives me some energy, but causes unwanted anxiety at uncomfortable times. I've been on it since 2/7/17 and haven't lost any weight. Although I do eat less. I wake up several times during the night now as well. If I take it first thing in the morning, it gives me horrible stomach issues, if I wait till lunch, I'm up all night. I take it with a snack around 10:00 am. It's been almost a month and a half, we'll see."

For Weight Loss (Obesity/Overweight) "Starting weight was 173 (5'5), combined Qsymia program with up to 1000 calories per day (no exercise) - recording with my fitness pal app definitely helps! I lost 18 lbs altogether in 6 months, where the majority was lost in the first 3 months, maintained during the rest with pills on/off. One thing I did not like about the medicine (especially in the first couple of months) is the side effects: dry mouth, anxiety attacks (which I never experienced before), and insomnia, but it subsided after a while. Regarding pricing, some insurance companies will allow for pre-authorization if you get your doctor to reason with them that it is necessary for you; this way, with a coupon you can pay as low as $35/month supply. Not a bad program overall."

I am on the 2-week free dose right now, and I bought the 30-day. It was $98.50. Really hoping this works and these side effects go away."

For Weight Loss (Obesity/Overweight) "The first week seemed fine enough at first: tingling in feet and hands, dry mouth, and diet soda tasted awful, so I stopped drinking it. After one week, I noticed the sluggishness when forming a thought, the forgetting things moments after the thought entered my brain, and tingling in my face. I also had some issues sleeping. Talked with my doc, and she confirmed all of this was normal due to the Topamax, and it was up to me to continue. I had already purchased the month's dose at the time I got my free dose, so I decided to stick it out and try it. The first day of the doubled dose was absolutely awful. I felt anxious, and my face was numb and tingly from 6 a.m. to 6 p.m., no exaggeration. I immediately stopped. Lost 12 lbs but not worth it."

For Weight Loss (Obesity/Overweight) "Run from this medication, it is toxic. I took it from Jan 26, 2016, to Feb 13, 2016. Here is how my doc prescribed it: a 14-day starter pack, then I started the higher dose on Fri, 2/12/16. Sat was my last day taking that poison. Today, I feel as if I'm withdrawing from something much stronger that I've been on much longer, and what's worse, this is the only medication I was taking. From day one, I felt so bad, but I thought it would get better. It never did, it only got worse. Here are/were some of my side effects: dry mouth, fast heart rate, anxiety, insomnia, nervousness, anger, gums hurting, blurred vision, rash. This is from 16 days only because I skipped a day or two. Trust me, stay away from Qsymia, it is not worth any weight loss."
