For Type 2 Diabetes "I started taking Mounjaro on 9/1. This resulted in the very worst month of my life. WEEK ONE - Super Nauseous, indigestion, stomach pain for 3-4 days of the first week. My appetite went from a 10 to a 2 (which was good). WEEK TWO - I had diarrhea for 3-4 days, along with sulfur belches, nausea, stomach pain. I ended up having to take sick days and go get an IV bag to recover from the dehydration. WEEK THREE - World-class nausea and vomiting. 3 days of vomiting so hard that I ruptured my esophagus. The entire month, if I was not having diarrhea, I was VERY constipated. I lost 9 lbs in one month, but I don't know if it was because I could barely eat due to the sickness. PASS!!"

For Weight Loss (Obesity/Overweight) "It has worked, very positive results. No side effects after 11 weeks. I was on Saxenda and had many side effects, including episodes of gout, diarrhea, and indigestion (sulfur-tasting burps). I highly recommend it but caution folks to not rush increasing the dose (2.5 mg, then 5 mg, then 7.5 mg, etc. -- I took each dose for 4 weeks before increasing -- a friend skipped from 5 mg to 10 and became very ill). My only complaint is that it is very expensive for me because my insurance will not cover it for weight loss."

For Weight Loss (Obesity/Overweight) "Started Nov 12 and am down 27 pounds. I have been on 5 mg for 16 weeks due to a shortage of 7.5 mg, so weight loss has slowed down considerably, but I am not gaining! Very sick the first week with nausea and one night of vomiting and diarrhea, but after that, only indigestion at night and occasionally like the next day after the injection! Pleased with the outcome so far! Disappointed with not moving up due to a shortage of 7.5 mg."

For Type 2 Diabetes "I am 5'9", 64 years old, and female. I weighed in at a high normal body weight, but my A1C was nearly 13. My doctor tried Metformin with fast and long-acting insulin and also Januvia, and my blood sugars were horribly unstable, dropping to 45 in the middle of the night and waking up over six hundred. I also have fatty liver disease with stage four cirrhosis. I've been on Mounjaro for eight weeks and lost 24 pounds, which still leaves me at the higher end of normal body weight, but my A1C fell to 7 after a month. I am on the 5 mg but wish I had stayed at 2.5 for a while, as the side effects like bloating, indigestion, and diarrhea have started again, and I don't really need a lot of weight loss. The fact that it breaks down fat in the liver and controls my diabetes is the best thing. The worst thing is the waves of nausea, fatigue, and dizzy spells I get in the first few days after taking it, but it's still worth it."

For Type 2 Diabetes "Started with 2.5 mg in January, which went very well. Then up to 5 mg. That was going great for 10 weeks. Then everything went downhill. Had a reaction of severe indigestion, nausea, diarrhea, backache, and overall body just not good. Took anti-nausea medicine, did not get rid of the nausea. Called an ambulance, after discussion, decided to wait since ER would not be able to administer more anti-nausea medication. Stayed in bed (I never do that), after 12 hours of pure hell, finally feeling better. Still feel like my body has been beaten up for 12 hours. It will take a day to fully recover. While the medicine does work, I’ve lost 13 lbs and my blood sugar stayed steady. This experience has me questioning whether it is worth losing a day every week in bed. The late reaction after 10 weeks has me more concerned. I will have to give this some serious consideration in my decision."
