Mounjaro plateau

Hi everyone

I have been on Mounjaro now for 3 months and 2 weeks. I was pleased with my weight loss on the 2.5 but noticed it started to plateau so I upped to 3.25 and then to 5mg this week. However I am not noticing the same suppression as I got early on, I thought by upping the dose this would return. Is it the case that the 5mg needs time to build up? Just interested in other people’s experiences. Thanks

I’m just under three months and I feel I’m plateauing on 5 but I’ve lost 2 stones. Trying 7.5 but it’s more money! My big problem is I’ve had 2 winders fail with a dose left in the dispenser! Got a 1 dose reduction off my next order but I’ve got the same issue again! Dial won’t move from 0 and supplier is saying I’ve fully used it when there’s clearly a dose showing in the pen! So annoyed!

Hi - it stops after 4 uses even though there is still a dose in did you know that? You can force that out there’s loads of videos online (obviously at your own risk because it’s only supposed to be kept for 28 days). How long have you been on 5 for?

Have you definitely only had 3 doses from those pens? The current pens look as though there is a dose left after you have had all 4 doses as there is residual liquid in it (some people use this and call it "the golden dose").

New pens are coming out any time now that will not have as much overage

Well unless our counting to 4 is wrong! However I’ve had 7 doses of 5. I do feel more hungry than I was so I’m trying 7.5. There’s a good 1/2 inch left in the pen. DH says it’s three too. Maybe we both can’t count!

About 1/2 an inch is what is left over after 4 doses. You can see and feel marker lines on the glass vial part of the pen. If the grey plunger is lined up with the one nearest to the needle end of the pen, then 4 doses have been dispensed.

It appears we cannot count then! Oh well.
