For Weight Loss (Obesity/Overweight) "I started on Zepbound 2.5 back in Dec 2024. No major issues in the beginning. It definitely helps control your appetite, and you feel sick if you eat too much. After going to 5.0, I got a little more nauseated and started noticing more dizziness, lightheadedness, and fatigue. But I was losing the weight, so I just kept going. After going to 7.5, that's when my horror stories started. I have taken only two doses but am stopping this stuff altogether. It has truly caused me extreme dizziness, shortness of breath, fatigue, terrible stomach pains, and diarrhea that won't stop. I have lost 37 pounds... great... but the suffering and pain that comes with this medicine... no thanks. I'd rather be a little overweight and be happy than the constant nausea, stomach pain, and diarrhea. Best of luck to you all, but I'm going to accept me for me."

For Weight Loss (Obesity/Overweight) "I am 64, 5'7" and weighed 245. Started Zepbound the second week of February, and as of September 1, have lost 65 lbs and went from a 42 waist to a 34 and never walked into a gym. Had some morning sickness at first, but got over it. You have to ask yourself, is the juice worth the squeeze? And yes, it is. Do the math: that’s between 2 to 3 lbs a week. My doctor discontinued my blood pressure medication, and my gout has gone away, not to mention how great I feel and look. You owe it to yourself if you are in need of losing weight. My BMI went from 39% to 25% as well."

For Weight Loss (Obesity/Overweight) "Second review. I'm male, 75 years old. Began taking 2.5 mg on January 12, 2025. Today is May 21, 2025. Weight dropped from 268 to 232.5 (35.5 lbs). Went to 10 mg on May 8. Took 2 weekly 10.0 doses in that time period. Suddenly, explosive diarrhea, sulfur burps, nausea, and fatigue began May 18. My PA has advised not taking my 10.0 injection tomorrow (my regular day). Think I may need to drop back to 7.5 — had no side effects at that level (or at 2.5 or 5.0). Had already decided not to go to 12.5 because I have a friend who was fine on 10.0 but encountered major side effects at 12.5. Still, even 10.0 may not be right for me. The weight loss is stunning; haven't been at this level in over five years — but for a BMI of 25, I still have over 70 lbs to go, so I don't want to abandon Zepbound altogether. It may take longer to get there, but that's fine if it means I can avoid side effects."

For Weight Loss (Obesity/Overweight) "I love Zepbound ❣️ I started on the low dose, and now I’m on the 7.5, and I have lost over 25 lbs. There are side effects, not bad enough to make me not use it, they include nausea, cramping, and loose dark stool. I am totally disabled and can’t exercise, so this was a great way for me to get lighter on my feet. Thank you. Good luck if you’re starting."

For Weight Loss (Obesity/Overweight) "This Zepbound is an absolute miracle! Prior to starting I was 210 and in less than two months down 18 pounds. My triglycerides dropped from 600 to 220. No real side effects other than constipation and nausea if I eat too much. Very grateful for this medication, don’t be afraid of Zepbound, it has changed my life in a very short period of time. Was on 2.5 mg for the first month and now started on the 5 mg with no issue. The food noise is GONE, which I never really knew was a thing, but as an overeater, I definitely understand what that means now. 10/10 all day folks."

For Weight Loss (Obesity/Overweight) "I have been on Zepbound for almost a full year. I lost weight quickly: 90 pounds. I was at my goal in 6 months. I had to go back 2 doses to maintain and stop losing weight. The nausea has not stopped. It’s better than in the beginning, but I still get it every time for 1 or 2 days after a shot. The diarrhea is terrible. It has never stopped. I get it on day 2, and it is uncontrollable. It’s been almost a year, so I would think some of these side effects would have stopped, but they haven’t. I also get sulfur burps for a day or 2 after a shot. I’m at the point where I might have to stop taking it due to the side effects. I love the weight loss, and I sure don’t want to gain it back, though."

For Weight Loss (Obesity/Overweight) "My insurance won't cover Zepbound. I get it through the 'Lilly Direct Cash Pay for Zepbound vials.' I started with 2.5 mg for 1 month and lost 12 pounds. I moved up to 5 mg and lost 30 pounds in 4 months. Total loss so far, 42 pounds! Starting weight was 184, height is 5'3'. Current weight is 142. Only side effect for me is seldom nausea. Price is $504 each month, and that includes the needles, otherwise, it's $499. Now that Lilly offers the higher doses for the same price, next week I start 7.5 mg. I will update again in a month or so."

I was nauseous, fatigued, and dizzy for 3-4 days after taking my shot. However, on the Zepbound, I have no side effects other than slight pain at the injection site for 2-3 minutes after I take my shot. After switching to Zepbound, I lost another 20 pounds in just 3 months."

For Weight Loss (Obesity/Overweight) "Started the shot on Wednesday, was kind of nervous. Ate small portions, so I wouldn't get nausea. Didn't really think it was working, didn't feel any different. It is now Monday, I have lost eight pounds. I'm never hungry, have to remember to eat, don't think about food really except fruit, it always sounds good. Absolutely no negative side effects. Started at 187, am now at 179. This is on my first shot! This stuff is amazing, looking forward to that second shot! It's expensive since state insurance doesn't cover it, and I only work part-time, but worth every cent!"

For Weight Loss (Obesity/Overweight) "I have been taking Zepbound for 8 months. I am on the highest dosage and 6 pounds away from my goal weight. I have lost 65 pounds. I do get nauseous around the 2nd or 3rd day after my injection, but it has not resulted in throwing up. I really don’t have much of an appetite. When I do eat, I’m not eating nutritional food as much as I should. This has resulted in muscle loss. I recently started eating more protein. I would recommend it, but just know what to expect, read over all the possible side effects and just be careful and be very truthful about how it makes you feel and what it does. Zepbound really has changed my life. I started Zepbound shortly after I was laid off from a job. I was there for 24 years, three months later my two littermates that were 16 years old went to the rainbow bridge. Had it not been for my weight loss, I would be a mess. Take vitamins, drink lots of water. Good luck."

For Weight Loss (Obesity/Overweight) "I just started taking Zepbound for less than a week now. I am 5 days in. I have not had any major side effects. I have felt very little nausea at times. I had a very mild tummy ache a couple of times. I felt a little dizzy the first day and then nothing after that. I felt very fatigued the third day but have been good since. I have lost 4 lbs so far. I am 5' 2" and weighed 161. I am down to 157 as of today (5th day). My goal is 130 at least. I don't feel hungry. I don't think about snacking. I forget to eat most of the time because I am not hungry. I have to remind myself to eat something. I eat very small portions and feel satisfied. I am loving this! I do recommend it to anyone wanting to lose weight."

For Weight Loss (Obesity/Overweight) "This medication saved my life! In the beginning, the nausea was very noticeable but worth every bit! I never really had a problem with my weight until after my pregnancies. I gained over 90 lbs with each of my two pregnancies. Being at over 300 lbs and only 5’1” was a miserable existence. I couldn’t breathe and was exhausted all of the time, not to mention pre-diabetic and very high blood pressure. It has definitely been a journey, but I stand by that this medication saved my life. I’ve lost 125 lbs. I still have a way to go to get to my goal, but I’m so happy to be alive to see how much better life can be! By the way, my A1C is now normal, and the hypertension has also resolved! I’m very grateful!"

For Weight Loss (Obesity/Overweight) "I started in January and have moved doses up monthly. This morning I took my 4th 7.5 mg dose. I did have a 2.5 mg pen malfunction and moved up to 5 a week early. I've been losing 1-3 pounds a week, for a total today of 28 lb loss. My goal is to lose 50. As far as side effects, they really aren't too bad for me. Daily Colace helps any constipation, which has not been much of an issue anyway. Occasional nausea is fleeting and is helped with Coke One. I know some are against drinking soda, but Coke One does not have sugar and has been my nausea cure for as long as it's been on the market. My appetite is diminished, but not gone. I've changed my eating pattern to several small, healthy mini-meals during the day instead of 3 'regular' meals. Zero cravings for junk food or much snacking at all. Part, I'm sure, is that I'm keeping those mini meals full of protein and vegetables. The only real issue that I've had is fatigue. It hits about an hour after the shot and lasts about 36 h."

The next day, the swollen lymph nodes seemed to have moved down, now in the chest/armpit area. On the 3rd day, one of my knees is swollen and horribly painful. I have absolutely never had any knee issues prior to the injection. If I get nauseous, drinking more water helps. At this start of the med, continuing is definitely not worth it."

Also, in the beginning, I would give myself the injection at night and then take something for nausea my doctor prescribed and no longer felt nauseous. Good luck, everyone, to a longer and better life."

For Weight Loss (Obesity/Overweight) "I’m almost 46. I have been struggling with weight loss all my life, joined food addiction programs, and tried other diets, and nothing worked. I lost some but gained it right back. I started at 220, but in numbers, I was not diabetic, so my insurance wouldn’t cover weight loss medication. My doctor worked with me for months and kept trying until it was finally approved. I did manage to get down to 186 pounds before starting on Zepbound. I have lost an additional 22 lb in 2.5 months! I’m at 164 now, and I haven’t been here in years. I can relate to many of the comments here. I don’t think about food, no cravings. I feel satisfied. I have been doing one meal a day, and I feel great. I don’t feel anxious, deprived, or hungry. I don’t worry about what I’m going to eat next. I don’t catch myself always snacking. It’s changed my brain in a way that I’m at peace. Just started on a 7.5 gm, and I did have some nausea just the very first day, but no other side effects."

For Weight Loss (Obesity/Overweight) "Started out great. Moved to 5.0 and had AWFUL vomiting on day 3 after injection. Dr. tried to move me back to 2.5 but Rx store was unable to get it. Went 5 weeks before it was restocked. Started 2.5 again with 0 effect. And I mean zero. Moved to 5.0 and the nausea is there, but so far, no vomiting. What concerns me is that I have suddenly been struggling with an elevated pulse and higher than normal BP. Wasn't an issue before, so not sure if it's related or incidental. May stop it because I just don't feel good. In addition over the 5 months of on and off again, I am down 4 pounds...and following a reasonable diet plan. Discouraged."

For Weight Loss (Obesity/Overweight) "I have had a good experience with Zepbound. So far, I have lost 30 lbs in 6 months. This is my take and experience. You will feel sick if you eat improperly. You're not going to lose weight and continue to eat like you have been. Butter, fat, oil, and overeating will make you feel nauseous. These drugs slow down your digestion. I learned that in the first 24 hrs. I was at a barbecue and piled the food on my plate like normal. I felt sick the rest of the day. I learned my lesson. Make sure you drink plenty of fluids. Since digestion is slower, other functions slow down too! (If you know what I mean). Don't starve yourself, that will make you feel sick too. I have found that avoiding too many carbs and eating high in protein is working for me. I'm hoping my brain is rewired for when I go off Zepbound. I don't plan on being on this forever."

For Weight Loss (Obesity/Overweight) "I started Zepbound about a week ago. Only had 1 injection, but for me personally, as soon as I did the injection, I immediately began to feel nauseated and dizzy for a good couple of hours, but then it subsided. I did have some anxiety about the side effects, and sometimes when I do have anxiety, I will feel nauseous and dizzy as well, so I really can’t tell if that was from the injection or anxiety. Either way, it stopped. Since then, I barely eat. I NEVER feel hungry at all, and when I do, I eat hardly a handful of something before I feel full and stop eating. I don’t know if that’s normal. I’m supposed to get 60 grams of protein a day. I drink 2 of those 30 grams of the Premier protein shakes, not my favorite, but it will do, and that keeps me feeling full for pretty much the ENTIRE day. I don’t snack at all anymore. Again, I’ve only had 1 injection but have noticed some immediate changes."

For Weight Loss (Obesity/Overweight) "Question: Why wouldn’t you use this to get a head start on a new life? I started on Monjaro for weight loss and had to switch to Zepbound after three months (insurance). I always dieted and would stall after 20 pounds. My ultimate goal was to lose enough weight to safely run again. After a year, I had lost 80 lbs and was able to start running. I just finished a half marathon, one year after starting this journey. The side effects of it are what is advertised; some nausea, it can hit you but goes away quickly, the heartburn was less with Zepbound than Monjaro, and the decrease in using the bathroom is a godsend for anyone experiencing IBS. The injection is not bad with the auto pen. Take the leap and change your life!"

For the first time in over 20 years, I am under 200 lbs. I feel great. I barely use my inhaler, my knees rarely hurt, and I can jog! My labs are all within normal limits, and I feel so much better about myself. I have very little side effects from ZB: nausea the day after I take it, intolerance to most alcoholic beverages, and I get hot after every meal. I’ll take those side effects any day if it means that I’ll continue to have my life back. I’m on the highest dose now and will continue until I reach my goal of 165. I’m 5’4'' and 44 yrs old. I’m not sure that I want to get back to my high school weight of 140 or less. Anyway, I’m not here to steer anyone, I just wanted to share how well it’s going for myself."

I’ve barely kept any food down except for a day and a half before my second shot. I can’t find a way to prevent acute nausea, and the vomiting is now making me weak. I knew there would be side effects, but for me, this medication doesn’t work for my body. I chose to discontinue the medication and will work with my doctor to see what other options may work for me. I have been unable to participate in family and home life, feeling trapped between being so sick I can’t leave my bed and spending a lot of time vomiting or feeling like I will if I try to move or drink water. I hoped this would be the tool to help me on a healthier path, and it’s not the right one for me, but I can see how it would possibly help others if they aren’t affected by side effects."
