For Type 2 Diabetes "I'm type 2 diabetic and was on Ozempic for quite some time and having difficulty getting my medication. My doctor changed me to Mounjaro for my diabetes thinking I would be able to get my meds. I started on the 5 mg since I had been on Ozempic. My side effects were typical slight nausea. I was trying to get my second month filled and the issues started with availability AGAIN. The 5 mg and 7.5 mg were on backorder. He increased my dose to 10 mg. I have experienced sulfur burps, but that is about it. I have not seen much weight loss, but then again I'm more concerned about my diabetes. Shame on the drug companies for dangling a medication that works to lower A1C and cholesterol and choosing to utilize it for weight loss where the insurance won't cover it. I'm not using this medication for vanity, it's for my chronic disease."

For Weight Loss (Obesity/Overweight) "I started on the 2.5 mg starting dose. After the second day, I was experiencing severe diarrhea, burping, nausea. These went away on Day 6. Very tolerable after then. I stayed on 2.5 for several months before going to the 5 mg dose, due to the intensity of my side effects. Started Day 1 of the 5 mg dose, and on the 3rd day after it I had tiredness, orthostatic hypotension (85/55 when standing up). At the 5th day, I am still having orthostatic hypotension - I maintained a water source. Spent 2.5 days without eating. I also vomited a couple of times during the 5 mg startup. Once this batch of side effects goes away, probably will be fine. I just think that a warning about the SEVERE side effects that make me functionally worthless should be discussed. I believe my side effects are a little more extreme than most, but folks should, at least, be informed."

For Weight Loss (Obesity/Overweight) "I love Zepbound. I was on Wegovy prior to switching to Zepbound and lost 20 pounds in 6 months. 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) "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 Type 2 Diabetes "Holy side effects. First, if you eat when you take it, it just sits in your stomach and you’ll be burping it for 12 hours. The headache is insane. Starts immediately. Then you are hit with 3 days of nausea, fatigue, and just overall fatigue. Just when you start to feel better, cue the insane heartburn! It took me 5 days to feel normal again. I’ll pass on this even though I lost 5 pounds the first week."

For Weight Loss (Obesity/Overweight) "Lifelong dieter here. Despite successes, the weight always crept back. Zepbound feels like a game changer thus far. I feel fabulous overall. Nobody knows of my decision to try Zep, yet already everywhere I go people comment on how healthy I look. I’m 73 years old, female, 5’6”, SW 185 and goal 145. I’m on my fifth week @2.5, with a steady loss of 2 lbs per week. Minor nausea on injection day with the abdominal injection. The tartness of gummy fiber/vitamins is great for relieving nausea. Periodic fatigue mostly on day two. Friday is injection day so I can crash on Saturday if necessary. I eat six small meals each day and try to get a total of 120-140 grams per day. I get food noise, but it’s good noise thinking about nutrient-dense and low-cal foods. Protein/collagen powders/snacks are essential to keeping healthy muscles, hair, skin. Drink water!!!"

For Weight Loss (Obesity/Overweight) "I started 3 months ago with the 2 ml, then 5, and now 7.5. I have been nauseous every single day for those 3 months. I have been constipated almost every week. I finally am able to go. I noticed that after the injection, I vomit every time the next day. I am 5'7 and weighed 233. I am now 209. The nausea is sometimes unbearable. I feel like not taking this medicine. Everyone's body is different."

For Type 2 Diabetes "I tried Ozempic for 9 weeks and thought I was going to die, so they switched me to Mounjaro. The 1st 2 weeks were okay, I just didn't have an appetite, but week 3 hit me just like Ozempic did. Total exhaustion. I've lost 5 lbs in a little over 3 days. I have side effects of sulfur burps, dehydration, constant nausea, falling asleep at all times, all-night vomiting, and diarrhea. I feel bruised from head to toe and have blurred vision. I'm telling people this for a warning. Read the reviews. People are constantly going to the ER because of these medications. I'm flustered because I found something that worked for my diabetes, but it is really bad for me. Since starting Ozempic up to now, I've lost almost 30 lbs... might sound great, but not when you can't function."

For Type 2 Diabetes "Constant nausea no matter what I eat. Muscle weakness and tired all the time. I’m feeling mentally down. Tomorrow will be my 3rd shot, and I’m seriously hoping these side effects go away so I can get type II diabetes under control. Probably losing some weight because I dread the nausea after eating so am not eating as much. The verdict is still out for me on this medicine."

The last 3 days I had 83, 89, and 90. I test first thing in the morning before eating. I feel bloated, nauseated, tired, no energy, and no appetite."

For Type 2 Diabetes "This is my 2nd post, I am on 7.5 mg of Mounjaro, and I have loved every moment of this journey. I was 243 lbs and lost 49 lbs so far since October 2022. I also eat a healthy diet and exercise. Stay hydrated because my side effects are dry mouth and constipation. I did, however, find out that if you eat carbs, sugar, or fried food, you will get nauseous and possibly throw up. Lesson learned. Stick to protein, vegetables, and fruit. I need to lose 34 more lbs to be at my ideal weight. I am still excited to be on this journey."

For Weight Loss (Obesity/Overweight) "I started in October and am now on 10 mg. I have lost 106 lbs. I feel better than I have in years. I’m 69 and will be 70 in August. I do more, I get out more, I’m involved again. I have 60 more to go. I’m not saying it’s been a bed of roses, but the good outweighs the bad days 95%. 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."

I do have nausea, but it goes away when I drink plenty of water/seltzer. I can eat what I want, but small portions, and I can put the fork down. I take the shot at bedtime. I have only used my arms. It does not hurt. I am happy this is working."

For Weight Loss (Obesity/Overweight) "With the initial injection of 2.5 taken before bed. I woke up with painful, swollen neck lymph nodes and extreme fatigue. 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."

For Type 2 Diabetes "Be careful when deciding to take this medication. I advise you to speak first with your doctor, and if you could find another way to lose weight, you should decide to go with something else. The side effects for some people are almost unbearable. I was 100% healthy before taking this. Now my blood sugar levels are low, I cannot wait for this to leave my system. It’s hard to work out, I feel awful. Ever since I stopped taking it, since my sugar levels are low, I have to eat more sugar, and it’s hard to eat. I feel nauseous, and it’s so hard to start the day feeling like this. Please beware, I know of people that are not even eating while taking this because they lost their appetite, and they have to blend their food because it won’t go down. The side effects at the beginning for many people are really awful. If you have to work and be productive, don’t take this medicine, you will regret it."

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’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) "Have been injecting Mounjaro weekly for a month now and have lost 4 kg, but here is what I learned… 1. Make sure you're fully hydrated before injecting the recommended dosage of the first 2 weeks, needles being 2.5 ml, as it dehydrates you big time and most of the time is why you are feeling nauseated, but keep hydrated, drink up. Eg. Powerade or Hydralytes… 2. Inject in the top thigh as it is less nausea feelings than injecting in the tummy. 3. Your body automatically tells you that you are full after a small portion of dinner (saucer plate size) as breakfast I craved Vegemite on thin bread, so maybe I was lacking either salt or B12 levels down. Lunch I ate a small amount too, but have snacks 4 times a day, even one sugar lolly made me feel better."

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 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) "I am starting my 3rd month on Mounjaro. I have been overweight/obese most of my adult life. I have lost some weight but not as much as I expected. I feel terrible - I suffer with exhaustion, constipation, indigestion, depression, and nausea. I just do not feel good. It has sucked the joy out of my life. I used to exercise much more when I was not taking Mounjaro. I don't want to do anything. I am wondering if it is worth it?"

For Weight Loss (Obesity/Overweight) "It's too early to say that Mounjaro has been life-changing, but it is certainly trending that way. My first week was a huge drop in water weight; I lost about 11 pounds. Weeks 2-4 it slowed a bit, and I'm down about another 5 lbs. I'll be starting the 5 mg tomorrow. 16 lbs in my first month is pretty darn good, I'd say. Very little side effects thus far: severe nausea, but it's fleeting; it sticks around for 30-60 seconds then disappears, occurring every two or three days. In terms of how I feel, the changes have been subtle but definitely noticeable. My appetite is absolutely gone for the first 48 hours after injection, then comes back gradually. By the 5th or 6th day, I'm thinking about food again on a regular basis. I do feel that I have more energy, and my willingness to do even small household tasks seems to be higher than it has in a couple of years. Everything just seems like less of a burden. I started at 441 lbs, and am hopeful I can get back to around 300 eventually."

For Type 2 Diabetes "I have been taking Mounjaro for 4 months. It works! I have lost over 30 lbs, and my A1C is coming down and is close to 7, down from over 8. I wish the doctors prescribing this medication were better trained so they could advise their patients what they can expect. For 3 months, I frequently got nauseous, but that’s the medicine working. I lost weight because of 2 actions from taking this medicine: it suppressed my appetite, I wasn’t hungry at all, and being nauseous further reduced my desire to eat. It worked for me when everything else failed, but you have to be able to cope with the side effects and stick with it."

For Weight Loss (Obesity/Overweight) "As soon as I began at the 2.5 dosage, I modified my diet radically to mitigate or even entirely avoid the dreaded side effects of indigestion, nausea, constipation, heartburn, and vomiting. I also embarked on a free-weight program to build muscle. Fortunately, I’ve experienced none of the unpleasant side effects. I’ve titrated up after each 4-week dosage and am now in the middle of 7.5 mg. My doctor tells me I have lost more weight than most patients have at this point. I also have chronic inflammation, which extra weight exacerbates, and I’m watching carefully to see that marker decrease. That’s the good news. Zepbound has completely changed my relationship to food. I consider myself a “foodie.” That’s now behind me. I remind myself that it’s been only 10 weeks. I’m hopeful that at some point, I will be able to enjoy more of the foods that were once such a large part of my life."
