Bupropion / naltrexone for Weight Loss (Obesity/Overweight) "I'm writing to track my success. I am 53, 190 lbs, and have lost 30 lbs in a year prior to taking this medication and feel I should and could do better. Day I April 12. Strange feeling in my left arm and a little foggy this morning with some mild stomach discomfort. And still hopeful."

Bupropion / naltrexone for Weight Loss (Obesity/Overweight) "I just started Contrave 1 week ago. I have been taking one pill in the morning, and yesterday was my first evening pill. So far, I have not lost anything. My doctor said it takes a month for it to kick in. I think I am eating more things I never eat but love (candy, etc.) because I am hoping the Contrave will stop me soon. After reading all these reviews, I have decided to go on the 1200-calorie diet and get some exercise to give the Contrave a hand. Side effects are dry mouth, a little dizziness, and some stomach cramps the first few days."

Bupropion / naltrexone for Weight Loss (Obesity/Overweight) "Nausea, dizziness, blurred vision, stomach ache are some of the side effects I felt after only taking 1 pill. That was two days ago, and I still feel off! Would not recommend if you have a low tolerance to medicine, I would rather be fat."

Bupropion / naltrexone for Weight Loss (Obesity/Overweight) "Female in her 30s, down 15 lbs from intermittent fasting & ketogenic diet. 50 lbs to go, wanted to help regulate cravings. I started out taking one in the morning, the first two days were great, it was easy to follow my diet. But days 3-5, I was a little nauseous & extremely fatigued/dizzy. It was so debilitating I went off it. I read that if you just keep with it you get used to it, but every time I’d try to take it I was instantly fatigued to the point of sleeping all day. My stomach was constantly sour, queasy, & it gave me mild diarrhea if you eat carbs and are not working out. If you can deal with being out of commission while your body adapts to the medication & are desperate to lose weight, I actually would recommend it. It’s not the healthiest option, but losing weight is worth a few months of medication if it gets you started. But if you already have a routine and don’t eat carbs, I wouldn’t suggest this, it set me back."

Bupropion / naltrexone for Weight Loss (Obesity/Overweight) "I've been on Contrave for 3 weeks now (5'7", 238 lbs, 42" waist). I haven't been too religious about it; missed a couple of days, but I haven't had any nausea or stomach aches. I did have dry mouth at night a few times (which I'm glad I noticed on this board because I thought I might have severe diabetes). So far, the drug seems to work well. I don't have any cravings, but I'm realizing that my eating habits are more psychological than physical. I paid $282 for it at Walmart, but after noticing on this board that I can get a discount, even better!"

For Weight Loss (Obesity/Overweight) "Overall, I really like this drug and hope to be able to continue taking it and finally lose this weight. I lost 3 lbs in my first week, though none in my second week. SW: 199 GW: 150. This is my third try with Contrave. The other two tries have come to an end because I get really weepy. This time, I am titrating up at a slower pace and that seems to be helping. Side effects: upset stomach and lightheadedness for the first 3 days after titrating up. I have found that taking Bonine (anti-nausea tab) solves this problem. Exhaustion on days 2 and 3. Sleeping better and needing less sleep to feel energized. Constipation. My insurance does not cover this medicine. The out-of-pocket cost at Target for 120 pills is $90 with the manufacturer's discount."

For Weight Loss (Obesity/Overweight) "I started using Contrave, now going on my 3rd week. I have lost 12 pounds. No side effects. I tried to make myself eat a full plate, I was so sick. My stomach ached so bad. I will never do that again. I will not force it. I can't wait to see in a month. I work out 6 times a week. Between the treadmill and Zumba, I am going to get there. Will keep you posted in two weeks."

For Weight Loss (Obesity/Overweight) "I have been taking Contrave for 12 weeks now and haven't lost any weight. In the beginning, I did have slight stomach upset and pains, but well worth it to lose a few pounds. Once my body adjusted, the side effects went away. However, I would lose a pound, then gain a pound, I never lost any real weight. Good thing was I didn't gain any weight. I lost over 50 pounds about 2 years ago with Qsymia, but hated my mood on it so much I couldn't take it anymore. My mood on Contrave was wonderful. I'm now off it and asking my doctor for a script for Wellbutrin."

Bupropion / naltrexone for Weight Loss (Obesity/Overweight) "Started the 3rd week of Contrave yesterday, was initially down 2 lbs and then 3 down but back to only 2 lbs. Got a cold last week, so have not been eating as much, but still nothing major. Started back to the gym also. First week, tired, slightly dizzy, but that was it. Second week, forgot one night and took the pill after dinner (about 30 minutes later), and my stomach was upset all night, but no vomiting or diarrhea, which would have helped! Third week, took two pills in the AM and several hours later, extremely dizzy and funny headaches. Same thing today, and still nothing major. I am not really seeing any major change in appetite at all. I don't really feel like this pill is working, which is sad because my insurance did not cover it, and I had to pay $99.00 for these things."

For Weight Loss (Obesity/Overweight) "I had been on this medication for about 1 year. I have paid for it out of pocket, it is very expensive. Weight is an issue I have battled with my entire life. I am 38 years old, 6’2”, 240 lbs. I experienced dry mouth to the point where my stomach was bloated because of the amount of water I was drinking, and I stunk with cotton mouth. The changes experienced in my digestion alone were very concerning. I have never had an issue with going to the bathroom ever, not even while using pain medicine in the past. With this medicine, I had to get prescribed laxatives just to use the bathroom half the time, and that didn’t work. Overall, I started using this for “weight loss.” Well, it says “with a healthy diet you COULD experience weight loss.” I did not in any way lose weight. When I came off the medicine, however, I did lose about 13 lbs. I maintain that proper diet as a life change, not a crash diet. Long story short, save your money, get yourself a program, and follow it, you will see results."

Bupropion / naltrexone for Weight Loss (Obesity/Overweight) "I tried Contrave, I felt sick, I have a stomach ache and heart palpitations. All this and only taking 1 pill. I left it for a day as I had just gotten back from an overseas trip and thought jet lag might have been an issue. I took one today and I've found I'm more hungry than normal, and my stomach feels off. Will not be taking any more, not worth the issues it is causing."

Bupropion / naltrexone for Weight Loss (Obesity/Overweight) "I started Contrave 4 days ago. Day 1 was okay, I felt slightly dizzy. On Day 2, I had the worst stomachache in my life, and I vomited 7 times. Day 3, I had the same pain and vomited at least 12 times. Today, I feel no side effects because I did not take it. The doctor asked me to stop the medicine and suggested trying Belviq."
