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) "Started with the initial 2.5 mg injections and experienced queasiness, and though my appetite remained, I got a sick feeling less than halfway through the meal. After 4 weeks, even though I was eating very little, my weight only dropped a few pounds. Then I advanced to 5 mg and my stomach was gassy and totally upset, I ate Tums constantly to control the acid indigestion. The worst part was to come, for one solid week, I was a total insomniac. I mean no sleep. This lasted a little over a week. I stopped with the injections after the first 5 mg one. It is now a month later and most of the symptoms are gone."

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) "So far the experience for me has been difficult. The weight loss is slow but pretty much steady. I’m experiencing nausea, stomach pain, and fatigue. I’m still trying to stick it out, hoping that it will subside."

For Weight Loss (Obesity/Overweight) "I started taking this in March 2024. I've had some weight loss (about 30 pounds), but not as much as I anticipated. I occasionally experience nausea and stomach pain, but it's usually after a very fatty meal (avoiding those types of foods minimizes this symptom for me). When I reached the 10 ml dose, I began having an itchy, raised red area surrounding the injection site that dissipates by the end of the week. I had one shot that didn't dispense the needle until I held it up to inspect it. I am happy I started this medication because I did lose weight (and hopefully will continue to) and was able to stop taking metformin! The worst thing about taking this medication is trying to get the prescription filled. I have had more issues trying to get my refills for Zepbound than any prescriptions for opioid pain medication (which I have taken in the past post-surgery due to an allergy to acetaminophen). At first, it was supply issues. Now it's preauths and difficulty staying at a certain dose."

For Weight Loss (Obesity/Overweight) "I have been on Zepbound for a month now, lowest dosage of 2.5 mg, and today I'm to start my second month with the next dosage up, but personally, I'm done. I've lost 7 pounds this August 2025, and though it may not seem like a lot to most people, it's quite something to those of us who have a very hard time losing weight. The thing is, how can a person be happy with the weight loss when you're miserable all the time? My first week went well, but come the second, the stomach aches/cramps and nausea are too much... every day, all day, through the night... sicker than a dog. I've heard good things about Zepbound, but the side effects are just too much for anyone to feel good about the journey it takes you on, and if the side effects only get worse with the higher dosages, then I might as well not eat at all for what little I can now, when I can. I'm 300+ pounds, and this was my last hope for any type of weight loss help. I don't recommend this product, the side effects outweigh any of the happy."

For Weight Loss (Obesity/Overweight) "I started taking Zepbound five weeks ago. I started with 2.5. My first couple of weeks were fine, but by my third week after that shot, I could not eat for 3 days. I tried even sipping on water and couldn't because of the nausea. My throat kind of burnt all the way down to my stomach, it felt like someone was squeezing the top of my throat. I just took my first shot of the 5.0 3 days ago, and I still haven't been able to eat because I'm so nauseous, and again my stomach's hurting. I tried yesterday to take some Rolaids, but that made me throw up. I haven't told my doctor, and I'm still going to continue taking it, but if this keeps up, it's not worth it. But I will continue to try maybe one or two more weeks, but if it just keeps up and is this miserable, I'm going to stop taking it. Hopefully, no one else has this feeling. But I didn't lose 19 lb in one month. I hope everyone does better on it than I am."
