Mounjaro Side Effects

Updated
Dawn Says:

This is my 4th month on Mounjaro and my 1st month on the 7.5 mg. My A1C is 5.7, down from 10. It is working great but the side effects from the 7.5 mg are rough. Extreme nausea, vomiting and diarrhea. My doctor wants me to increase to 10 mg but I can barely handle the 7.5 mg. Has anyone else experienced these side effects and do they eventually go away?

I am just ending the 7.5mg injections as well and the side effects (nausea, vomiting, and extreme diarrhea) have me basically incapacitated! I’m down only 14 lbs (thought I would have been down more by now). I don’t think I can continue with a higher dosage.

This is my first month (2nd week) taking 5mg of Mounjaro. Still nauseous on day 4, but better than days 1-3. My main concern is some itching in my mouth. No swelling, just slight itchiness in my mouth, that started soon after the injection. Should I be worried it will increase with dosage increases?

7.5 was the worst for me. The 10mg was better. Just started 12.5 and the nausea is back but no where near as bad as the 7.5. I barely have an appetite.

Typically, once you are on a steady dose of a medication, the side effects hit their peak after about 4 to 5 weeks of taking it, once your body gets used to the medication, and dosage, then they begin to taper off in severity, before going away. If yours are severe, or do not go away, you should consult your doctor as the medication, or dosage may not be right for you.

The FDA does list Mounjaro as being known to cause the side effects that you've all described, along with headaches, loss of appetite, and dizziness.

Ref: Mounjaro Information

How are you doing, now?

I've been on Mounjaro for 3 months. I started with 5 mg and am now at 12.5 mg when I started getting a rash, severe itching and now bruising at the injection site.

My very first dose of Mounjaro 2.5, I experienced awful neck pain and was extremely tired. I thought maybe the neck pain was just a coincidence. The second injection of 2.5 was fine. It just made me very constipated. I waited 12 days for my 3rd injection because I was still feeling very full and constipated. On my 3rd injection, I developed swelling at the base of my neck on both sides. The swelling is about the size of half a baseball on both sides. I now have pain in my jaw line, down my neck into my chest and back of my neck. The swelling is still there after 7 days. I did go to the ER, they checked my thyroid and lymph nodes and my blood work. All came back normal. They have no explanation as to why this is happening. Has anyone else had any similar symptoms?

One day after my second dosage of Mounjaro at 2.5mg I am experiencing extreme sleepiness along with excessive burping and gas. Is this normal, and will it pass?
