For Weight Loss (Obesity/Overweight) "I’m a 6’4", 275-pound male, 62 years old - no diabetes or health issues, on no other meds. Obtained prescription via Dr. and took the first 2.5 mg injection on Dec. 24. Lost 10 pounds with the first 3 shots, then Dr. said I could go to 5 mg (saved the last 2.5 mg pen for future use) because weight loss had stopped. After starting 5 mg, lost 2 pounds in 2 days - so combined weight loss using 2.5/5 mg is now at 12 pounds in six weeks! No significant or terrible side effects except some constipation, intermittent fatigue, and minor chills at times (not a lot - could just be the cold weather). I've yo-yoed up and down with weight for years. Because of my size, I can eat a lot of food - but this drug has significantly reduced my appetite, and I have more energy overall. I can’t wait to see the results in a few more months. Zepbound has so far been perfect for me. I don’t mind the $550 price (with the Lilly savings card - has been hard to get CVS to make it work, but that’s another story/nightmare)."

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."

For Weight Loss (Obesity/Overweight) "Best method for weight loss and keeping the weight off. I've lost over 100 lbs and am finally comfortable in my skin again. When you change mg dosage, fatigue could be concerning, and it does happen. Working out helps, making sure you stay hydrated, and working out was the biggest help for me. I did have constipation, and it was managed. I did have hair thinning and started taking Nutrafol. I've struggled with my weight my entire life. Not anymore. I wish we could add photos, but we can't. Portion food sizes of what you can eat are minimized. The sugar cravings were gone. Not only did those cravings disappear, but so did the cravings for food that your body turns to sugar. For example, I haven't eaten a potato chip in over 7 months. No desire for breads, mayo, Miracle Whip, and numerous other things. I FEEL so much better. It is costly, but so is poor health and obesity. I wish big pharma would realize how many Americans struggle with obesity and cover this through insurance."

For Weight Loss (Obesity/Overweight) "Only two weeks into it (2nd shot) but working, do not feel hungry, eat small portions and eating because I know I need to. Do have to take a laxative as I get constipated, day after shot do feel some fatigue and take a nap in the afternoon."

For Weight Loss (Obesity/Overweight) "I am a 55-year-old female, 5’7 starting weight 250, started Zepbound 6 weeks ago. 1st month, 2.5 — moved up to 5 2nd month. Probably the most annoying, almost immediate side effects were GERD, bloating, and constipation. However, this did improve quickly when I added more fiber, avoided high-fat, saucy foods, and ate less. I do agree with the others… that it definitely helps your “hunger-food brain.” I can skip a meal without even noticing. I fill up eating a quarter to half of what I would normally eat. I begin getting nauseated while I eat, which makes me stop eating, of course. Now that I've increased from 2.5 to 5, the nausea is a little worse, but intermittent and tolerable. Hoping this will improve once my body adjusts. Overall, still very thankful for this opportunity to try Zepbound. I'm trying to find some type of a meal plan to follow, with sufficient protein and fiber, as well as other foods or supplements to prevent muscle loss, hair loss, constipation, and fatigue."

For Weight Loss (Obesity/Overweight) "On week 5 of Zep. Goal to lose 20-25 lbs. Received a 2.5 mg 'loading' dose, I split it into 1.25 doses 3 days apart for the first 2 weeks as I tend to react strongly to meds. I had a bit of anxiety and fatigue on this dose and appetite suppression that waned by week 2, so I increased to 2.5 in one shot for weeks 3 and 4. Less anxiety/fatigue but more nausea and constipation, still manageable. I received a 5 mg dose in the mail at week 4 but had already lost 15 lbs on the 2.5 dose for 4 weeks. Week 5 - I tried the 5 mg. The next day, I was so sick to my stomach and nauseous that I struggled to eat or drink at all. I was dizzy and felt terrible, depressed, and kept getting the long bouts of hiccups. I will be at goal soon and plan to switch to metformin to maintain weight. For me, this med is miraculous, but I do not feel great on it. (For reference - I have a mental health diagnosis and pre-existing mild gastrointestinal issues, MTHFR gene variant)"

For Weight Loss (Obesity/Overweight) "My experience is a lot better than I was expecting. I'm on the 2.5 mg a week. So far, the side effects are manageable. I barely get nauseous, but the constipation is real. I really like the once-a-week dosage because I don't particularly care for needles. My weight loss is slow, mainly due to a lack of working out. I'm extremely fatigued and just want to rest. The fatigue hits me early in the morning and late in the afternoon. Stay hydrated!"

For Obstructive Sleep Apnea/Hypopnea Syndrome "My stats on the front end of the Zepbound medication were 293 lbs at 6 feet tall. BMI was well over 40. I had constant fatigue and didn't sleep well (I am also on a CPAP). I started on 0.25 mg for 1 month and lost about 6 lbs. I then went to 0.5 mg for the past two months and have lost 18 lbs for a total of 24 lbs in 3 months. I have asked to go to 7.5 mg to help me get to my weight loss goal. My main side effect has been constipation, Miralax is helping with that. I also run 4 times a week, and exercise is very important when on Zepbound."

For Weight Loss (Obesity/Overweight) "First things first. I'm a 40-year-old woman. My height is 5'9", and my starting weight was 214. During my first month on Zepbound 2.5 mg, I experienced fatigue, dry mouth, and slight constipation. I'm on my second month dosage of 5 mg now, and I'm experiencing nausea and migraines. This is my sixth injection, and the weight fell off during the first month, and now I'm at a standstill. I'm weighing in at 195 for the last 2 weeks. During my first month, I had no carbs at all. I made sure I had at least 120 g of protein a day, and I weight trained four times a week, getting my goal of 10,000 steps a day. I haven't kept that same training routine these past two weeks, which is why I probably haven't lost any weight. I'd say the medicine really works. I'm not looking to stay on long-term. Since I hit 40, I've struggled with weight, perimenopause, etc. This has been a game changer."

For Weight Loss (Obesity/Overweight) "I started in January 2025 with the 2.5 dose. For the first two weeks, I experienced nausea and diarrhea off and on. For the last two weeks, I was fine. I am on my second week of 5 mg. The first week, I was so sick - I take the shot late Friday afternoon - I was in bed most of the day on Saturday with nausea and fatigue. I did vomit once. Sunday was the same. The rest of the week, I felt fine. Second shot last Friday - I was okay on Saturday - able to function but very nauseous. Woke up on Sunday and spent most of the day in bed due to nausea and fatigue. The anti-nausea medicine helps but not so much for me. Today I am functioning with some nausea. The benefits of this drug are obvious. I don't eat as much as I did before the medicine. I've lost 16 lbs so far. The nausea bothers me. I should be able to function and not get sick every weekend after a shot. I no longer have diarrhea - I am constipated instead. When I take Miralax, I cannot think about it or I get sick."

For Weight Loss (Obesity/Overweight) "I have been taking Zepbound for four months and have lost 23 lbs so far. In terms of facilitating weight loss, it is a miracle drug. I eat less without feeling hungry, and I don't think about food. But there are definite side effects-diarrhea (this is the worst-can last for days), constipation (yes, the diarrhea quickly turns to constipation), heartburn (easily controlled), and some fatigue in the first 24 hours. I was on 2.5 for 1 month, then went up to 5 (ish). For me, the worst side effects kick in at 5. I am getting the medication in a vial so I can easily adjust the dose a bit. A couple of weeks ago, I went down to 4.5, and the side effects were much less severe. I'm experimenting to see where in the 4.5 to 5 range I get a balance between weight loss and side effects that I feel comfortable with. Right now, I am still losing weight. After another 10 lbs, I will be at a healthy weight and hope I can decrease the dose to maintain weight loss and reduce side effects."
