For Weight Loss (Obesity/Overweight) "I have only taken it for 5 weeks. I have had a lot of nausea and acid reflux. Hopefully, they go away, but when I started, I weighed 174, and 5 weeks later, I am at 165, so it's working. Side effects seem to be decreasing, so I'll keep going for now."

"My doctor prescribed Mounjaro after seeing my weight increase. First, I am a bariatric weight loss patient - 6 years out. I lost 80 lbs after my surgery and gained 30 back since. So yes, there is reason to be concerned. The month supply of 2.5 mg dose produced a 5 lb weight loss, and my appetite was suppressed somewhat. But more noticeable is the craving loss. They completely went away. I'm anxious to see how the 5 mg dose works. Some annoying side effects, but nothing drastic so far. Light nausea and diarrhea (subsides somewhat following the first few days after dosage). It took me a bit of time to get it together and start making healthy choices. I was in a very stressful work environment and chose to retire a little earlier than planned. Now, I work part-time from home now so I can take care of myself better. That's just me... I get overwhelmed and spiral. But even seeing this small amount of weight loss from the 2.5 dose has given me lots of hope and motivation!"

For Type 2 Diabetes "I started Mounjaro 7 weeks ago. The first shot made me so nauseous and have such bad abdominal pain that lasted for 12 hours. I almost went to the ER. I told my doctor about my experience, and she gave me Zofran and told me to continue dieting. Fast forward to this weekend - took my shot on Friday morning, then spent all day Saturday and Sunday projectile vomiting (it literally ended up about 7 feet from where I was standing), uncontrollable diarrhea, disgusting sulfur burps, horrible heartburn, and dizziness. Finally, I decided to go to the ER and got treated for dehydration. They told me to follow up with my primary doctor to talk about the best way to continue the medication. After this experience, I am NEVER taking this drug again. While I've lost 25 lbs in the past 7 weeks, I believe it's mostly because I've been afraid to eat anything. I will continue to eat healthy and cut carbs and sugars, but I won't be taking Mounjaro again."

For Type 2 Diabetes "As of today, 9/5/2022, I have been on Mounjaro for 5 weeks. I have experienced upset stomach, nausea, weakness, and tiredness. I am on 2.5 mg. Hoping symptoms start to disappear. I am a Type 2 diabetic, and the pills didn't seem to help. I am in my 60s, so was wondering if that mattered. I'm not sure. I would like to continue the Mounjaro, but if side effects persist, I may have to try other options."

For Weight Loss (Obesity/Overweight) "I've been a yo-yo dieter for as long as I can remember. This is by far the best thing I've tried. I lost 11 lbs in the first week, this really does work to decrease your appetite! My diet doctor gives me injections and told me to follow what is essentially a keto diet (no carbs or sugar - 8 oz of protein and as many veggies as you want), in conjunction with intermittent fasting (16 hours fasting, 8 hours allowed to eat). There is NO WAY I'd make it through 16 hours of not eating without this! I feel very slight nausea sometimes after I eat, but not enough to affect my day-to-day activities. This is a game changer if you have struggled to lose weight as I have!"

For Weight Loss (Obesity/Overweight) "You do lose weight, but the waves of nausea, vomiting, severe constipation, and hypoglycemia are so unpleasant, and if you escalate and find it too much - it lasts for a whole week. Consider liraglutide daily, much easier to titrate, and if you escalate and find it too much, you can lower down and only have one day of downtime."

For Weight Loss (Obesity/Overweight) "I have slowly lost weight. I have taken it for 8 weeks and have lost 18 lbs on the 2.5 mg dose. It makes me very nauseous and causes GI upset. But overall, I think slow weight loss is probably best anyway for long term."

For Weight Loss (Obesity/Overweight) "I've been on the shot for 5 months now, and at first, the appetite suppression was strong, with no side effects. After I went up in dose month two, I had extreme bloating and nausea to the point where I nearly took myself to the emergency room. Since then, the side effects have gone down, and the only one I deal with regularly is heartburn. Ask your doctor for Zantac and keep it and Tums on you at all times. Thankfully, it has mostly subsided, and I'm down 80 pounds with moderate exercise in 5 months. I have basically 0 appetite most days and have grown to work with it. I'd give it a 4/5. It's not easy, but if you're serious about losing weight and taking back control of your body, do it. Make sure you work out and follow a strict diet while you're doing it to get the most out of the medication. ALSO! Go to the manufacturer Lilly's website and sign up for the savers card. Saves me $300 a month with insurance."

For Weight Loss (Obesity/Overweight) "I am 5'2" and 46 years old. I started Zepbound on 8/20/2024 at 166 pounds. I took the 2.5 mg dose for one month, then increased to 5 mg in Oct. and Nov. I had very mild side effects, and I steadily lost weight until last week. I have now increased to the 7.5 mg dose, and the nausea and diarrhea are pronounced. I'm down 30 pounds, but I may switch back to the 5 mg dose if the side effects don't subside."

For Type 2 Diabetes "It’s been 2 years. Yes, there were challenges. Some nausea. Lot’s of constipation. Some fatigue. And mostly good aversion. I understand fully the phrase eat to live. This medication was/is a game changer for long-time diabetes sufferers. I lost 50 pounds. Got off of insulin shots. Cholesterol meds. BP meds. I am over 60 years old and feel better than I did at 40. I would rate my experience on Mounjaro on a scale from 1-10, a solid 10. Everyone’s journey is unique, based on many different factors. I would rate my journey as successful."

For Weight Loss (Obesity/Overweight) "I’m a 58-year-old woman. When I started Mounjaro, I was at 172 lbs. I am taking 5 mg. On the first injection of 5 mg, I had hives, but the next day, with allergy medication, it went away. I had a little bit of nausea off and on every time I took an injection. The worst part about this medicine is I feel cold all the time and fatigued. The fatigue goes away after a couple of days. I just took my 4th injection of 5 mg and will move up to 7.5 mg next week. So far, all good. I did notice I got pretty hungry 2 days before it was time to take my 4th 5 mg injection, which to me said it lost its effectiveness. I did struggle with those 2 days trying not to go back to old habits. I have lost 20 lbs since starting Mounjaro, and all of my blood work is much, much better. My A1C is down 2 points!"

For Weight Loss (Obesity/Overweight) "I have been on Zepbound for 6 months. I'm down 48 pounds. I ride a recumbent bike 25 minutes a day. My symptoms have been varied but mostly feel like morning sickness. Usually the 2nd day after the injection. Due to insurance, I do 3 months on each 2.5, 5, and on the 3rd week of 7.5. This one hit me worst, nauseous for 3 days now."

For Weight Loss (Obesity/Overweight) "I started using Zepbound on October 31st of this year. The beginning dosage was 2.5 mg. I started to lose 1-3 lbs. a week. The dosage was increased to 5 mg, which I started on the 4th week. Current total loss of 11.5 lbs. My provider has suggested that I increase the dose to 7.5 mg for my next refill. I do have side effects: nausea, constipation, dry mouth. My appetite has diminished, but I have to make a conscientious effort to eat. Cravings for specific foods have gone as well. I have a fear of needles, but do not feel the injections or any discomfort associated with normal 'shots.' Overall, my experience has been a good one, but it is still early."

For Weight Loss (Obesity/Overweight) "After my second 2.5 shot, the side effect symptoms are too much for me to handle. 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."

For Weight Loss (Obesity/Overweight) "First dose 2.5 today, and already my appetite is none. I only ate a very small portion plate and drank nothing but water. It wasn't until I tried to have my daily cup of coffee when I felt very nauseated after only a few steps. Day 1, and I'm here to say I know it's going to work out (I'm hoping I can build my coffee/frappe tolerance back up, I LOVE my coffee)."

For Type 2 Diabetes "Horrible experience taking this drug. I do not recommend taking this medication unless you want to die. I started taking 2.5 mg 6 days ago. Day 2 and 3 had no appetite and ate very little because the thought of food made me sick. Day 4 and 5 developed nausea, severe abdominal pain, and indigestion unrelieved by antacids. I also have lost five lbs because I am unable to eat or drink anything. I do not have any energy or feel like doing anything. Day 6 and I still feel sick. My fasting blood sugar this morning was 224 even though I am not eating or drinking hardly anything at all. It is noon, and I haven’t eaten anything because I’m afraid I will throw up. My heart rate is 120 and normally runs in the eighties. My doctor is out of the office this week for holidays. Just hoping and praying I don’t wind up in the emergency room. I will never inject this toxic stuff into my body again. I also read that it can cause thyroid cancer."

For Weight Loss (Obesity/Overweight) "I am a 45-year-old female starting weight 243... I just took my fifth shot a few minutes ago, and I have lost a total of 26 lb since my first shot. Food noise is completely gone, and I find myself not able to eat anything until the day before my shot. I do drink a lot of water and have no cravings for sweets like I used to. I have done moderate exercise in the evening and tried to force myself to eat some source of protein throughout the day. I also take women's one-a-day gummies and I feel fantastic! The very first shot I took, the first few days I felt horrible, like I had the flu and had been hit by a bus. Since then, no side effects except for very mild nausea, which I take promethazine to help, and it does wonders. My sleeping patterns have gotten better, and my energy has increased. It states for my age and height at 5'9, I should weigh 167. I honestly feel like I would look very sickly if I got that small, so my goal is basically just to fit in my pants from last summer, lol."

For Type 2 Diabetes "I just took my fourth injection, and I couldn’t be more excited! I’ve lost 10 pounds in three weeks, my appetite is controlled, I feel like I’ve finally got some hope to get my health where it needs to be. My morning fasting glucose is close to 100 (always near 140), no more crazy spikes hitting 200-300. I do get very tired the day of each shot. The first three days or so of my first injection, I was so ill (sick stomach). I got some Zofran, and that helped tremendously, so I’ll expect to need that with each dose increase. Looking very forward to 5 mg next week :) Ins won’t pay for it yet, even though I’m type 2, but I’ve got a coupon for it and paid $25 a month. Thank God, or I couldn’t get it, hopefully soon it will be covered."

For Type 2 Diabetes "In November 2022, my ACI was 7.4%, and I weighed 258 pounds at 67 years old. The wake-up call was when I renewed my life insurance, a big jump in premium due to the AC1 and weight. I was now tagged as a Type 2 Diabetic. I was referred to an endocrinologist who did extensive blood work. It was agreed to go on Mounjaro 2.5 mg. The first week I suffered some side effects such as nausea, constipation, and acid burps. Within 10 days, the symptoms subsided due to stool softeners, lots of fruit (berries), and Nexium. The first month I dropped 10 pounds with no dieting, just was not hungry at all. I had no cravings, especially for sweets like cookies, donuts, and candy-all things that I used to eat. Fast forward to March 2023, I am down to 217 pounds and 20 more to go. I am now on Mounjaro 10 mg, it's a bit strong, but the results are fantastic. My AC1 is now 5.6%, which is fantastic. The bad news is nothing fits- all new suits for the spring."

For Weight Loss (Obesity/Overweight) "Zepbound made weight loss easy. I have lost 40-50 pounds on it. Very little side effects outside of a little nausea occasionally. It’s so easy to use with the prefilled injector. I am now maintaining, and my doctor is happy with my weight. I’m so excited, I haven’t been this thin in 30 years! The only downside for me is the cost. It’s quite expensive even with the coupon. I’m not sure how much longer I can keep paying at this price."

For Weight Loss (Obesity/Overweight) "I am a 49-year-old female. Started on 2.5 mg of Zepbound at 201. Lost some weight quickly and got to 191, then stopped. Second month, they bumped me to 5 mg. I only got sick once. It was nausea. I started losing again. Got down to 185. Then, for reasons I can’t explain, I gained 2 lbs despite walking and tracking food. On my 3rd shot, I was very lethargic for a whole weekend after the shot. I have no energy, and I am taking nothing else. I hope it goes away soon and I start losing again. It’s not a magic bullet. You have to track your food and exercise too (which is hard with lethargy)."

For Type 2 Diabetes "I’ve been taking 2.5 ml for 4 weeks and had few side effects apart from zero appetite, a little nausea, and a migraine (think the migraine was due to not eating). Now, week 5, increased to 5 ml and a different story: quite a lot of nausea, diarrhea, headache, and tiredness. Also again, total lack of appetite. Fortunately, these side effects more or less calmed down 2 or 3 days after taking the dose. I’m hoping it’s a temporary thing when you take a new dose - I can live with that."

For Type 2 Diabetes "I have been on Ozempic 2 mg since it came out. When I couldn't get it due to shortage, I was prescribed Mounjaro 5 mg. Five days after eating my one meal a day, I intermittent fast, and I started vomiting. I spent the whole night throwing up every half hour. I figured it was a side effect and hoped I would improve. I had stomach and back pain, weakness, and was unable to eat. I was in bed until I had to get up and sit due to pain, sleeping off and on. I could only drink water. I got worse and finally, five days later, had my husband drive me to the ER. I know I should have gone sooner. I didn't take a second shot. I had a CAT scan and was told I had a bowel obstruction, and I would be admitted and there for a few days. If they couldn't resolve it through a tube down my nose, I would have surgery. Luckily, it was resolved by the nasal tube, but it was awful. My medical care pharmacist told me to try Mounjaro 2.5 mg. I was worried but did it. I didn't get nausea, but I had all these other side effects. I quit taking it."

For Weight Loss (Obesity/Overweight) "I started on a low dosage (0.25 mg/weekly) two weeks ago. It actually decreased the appetite without any side effects. I am exercising due to an increase in energy. I actually eat one meal a day, I only eat until I am full. I tried to eat more but got very nauseous. At the end of two weeks, I have lost 30 lbs. The exercise allows me to keep my muscle mass. It's great to be able to move more easily. One side effect I noticed also was increased focus in my thought patterns. It is a blessing for that. Multi-tasking is made simpler."
