Mounjaro 5mg side effects

I’ve been on 2.5mg for 4 months and have lost 2 stone but food noise was coming back and suppression wasn’t as strong so I moved to 5mg on Thursday. I felt ok on Friday but today I’ve become progressively more nauseous and now I’m all flushed. Do the side effects peak and then tail off before the next jab or is this it for a few weeks? Really worried about work on Monday.

Well done on your weight loss!

I struggled a bit moving up to 5mg. Like you, I was fine on 2.5mg but upping the dose made me really nauseated. I've done 4 weeks on 5mg now and it seems I'm OK on jab day (Saturday for me) but quite nauseated for the following two or three days. By Tuesday/Wednesday I'm absolutely fine. Nausea has got less severe as the weeks have gone on. I sip peppermint tea and think grateful thoughts that I'm not actually being sick! It's a really unpleasant feeling, I hope it passes for you soon.

Yes on day 3 of 5mg, I felt really yucky. I took Pepto bismol, drank lots of water and later on had an early night. I felt totally back to myself the next day.

Fortunately I’ve felt loads better today!

I’m about to start my second 5mg pen and it’s absolutely fine.
I do experience a bit of lower stomach discomfort or perhaps a different sensation after eating but otherwise all ok.

Apart from constipation that I had on 2.5 as well.

I am going to stay on this dose for as long as possible and am in no rush to increase.
