Would you use remaining 7.5mg doses or move up to 10mg?

Hello There

I have lost 8.5 stone on mounjaro since March 2024, and still have 3st to go. My weight loss has been very consistent and I am currently on 7.5mg.

I definitely need to go up a dose. I feel like I am injecting water now. My food noise is back and my binging habits are making a slow return. I was going to order 10mg last time, however I had a good weight loss the week I was due to order my pen so reordered 7.5mg - that was clearly a mistake as this week I have gained 2lbs (absolutely deserved to), and aside from that one week losses have been like 0.2lb - and they have been hard fought for!

I will be ordering 10mg next time. However, I still have 2 doses plus the extra dose in the 7.5mg pen. Would you continue using the 7.5mg doses for the next 3 weeks or would you count clicks to have 2 weeks at 10mg via the pen (80 clicks)? Or would you just cut your losses and buy a 10mg pen early?

Just keen to understand what other people have done.

I am also under pressure from family to not increase my dose due to their concerns about being on the jags long term, and trying to wean off them eventually. I know on some level I will likely be on them indefinitely, but I would like it to be as low a dose as possible. Just including that as context for why I am a bit indecisive about what to do!

Thanks in advance.

When this happened to me twice, on 10mg and 12.5mg, my prescriber advised me to take the remaining 2-3 doses in my second pens every 5 days to increase the concentration, but also not to waste the pen. It worked a treat both times and suppression and satiety returned so would advise this.
7.5mg taken every 5 days is equivalent to 10.5mg in a week and its a lot easier than taking multiple doses or messing with your pen.
Don't worry too much about having to go higher up, I went up to 15mg and now back down to 5mg for maintenance and it is working fine with good suppression and satiety and no food noise, so it doesn't mean you are stuck on the higher doses.
I know people worry about the jabs but research is really positive on their treatment in inflammation, heart disease and cancer etc
Well done on your losses so far and keep going, good luck 👍

So I'd inject a full dose then before pulling the needle out click another 20 (to make 80) so you only have one injection

I would try my hardest and do another 2 weeks of 7.5 then all the bonus dose 3rd week as it should be more.. but if I found i was really struggling then I would jab my next 7.5 at 5 days to get the level in my body up..

Thanks all for your help!
I really like @Mysticmaiden 's idea of jabbing the 5 days just until the end of this pen. I really should have ordered a 10mg pen, but I suppose hindsight is a wonderful thing!

I did exactly this , I started March 25 stopped October 25 after 4.5 st loss , restarted 9 weeks later due to gain
lost the gained weight but had a stall on 12.5 so reduced 3rd to 6 days and and 4th although the scale didn’t move the effect of food noise going
min going up to 15 this week and if the stall continues I’m going to split jab on second pen (10mg Friday morning / 5mg Monday evening) as there is success stories of split jabbing to have a stable level of MJ and avoid food noise at the end of the jab week as well as stable sugar levels

also to add when I was on 10 first round (3 pens) I had hunger pangs quite often , scale was moving but I think I was too low on carbs/kcals so got hunger pangs instead. It disappeared on 12.5 (nothing compared to the hunger when I stopped completely that’s something on a very different level)

Split dosing never worked for me, splitting a dose in 2 meant the first dose wasn't high enough to raise drug concentration high enough to give suppression and satiety. I tried it for many weeks with different combos like 50:50 75:25 etc but didn't work and I was always hungry.
