How long have you stayed on 2.5?

Just wondering how long people have found the 2.5mg mounjaro dose useful for. I’m at the start of my weight loss efforts and have just ordered pen no.2, another 2.5.

It was only week 3 that I found I had any notable or consistent appetite suppression. I’m now in week 4 and hoping that as the 2.5 dose took a while to kick in, it might take a while to wear off too and I can save myself a bit of money by not having to move up too quickly!

I’m 42 weeks in and on the 7.5mg. Everyone is different and you can’t base how you will react to the medication on everyone else’s experience unfortunately. Some people don’t have any effects at all until the higher doses. The 2.5 and 5mg are usually the same price so I always advise to buy the 5mg, that way you can just take half a dose but if the suppression wears off you can titrate up during the month.

I’ve just started looking into Mounjaro.

have I got this right, if you order a 5mg pen and feel it’s too much, can you dial the dose down to 2.5 instead of 5 or is the dose pre set to 5? Sorry I am clueless but this was one of my questions.

I stayed on 2.5 for 3 months, as I had good weight loss and enough suppression. Now on month 3 of 5 mg. If you aren't sure, you could do as Time4changeagain suggests, and buy the 5 mg pen to hedge your bets. It does seem to be a very individual thing how 2.5 works or doesn't work.

@WivVestwood
Yes you can, each pen has 60 clicks per dose when turning the dial to number 1 for the injection. For half a dose of any pen you would count 30 clicks and just inject that amount

Thank you for replying. Really helpful.

4 months, but I’m not chasing appetite suppression.

lovealongbath · 24/03/2025 08:25

I have taken…

2.5mg for 10 weeks
3mg for 5 weeks
3.25mg for 2 weeks
this week I plan to move up to 3.5mg

I have lost 2 stone 4 lbs in 17 weeks.

Edensnapz · 24/03/2025 08:27

OP, I've just done exactly the same. Just ordered 2nd 2.5mg pen. Supression has been good from the start and if anything has got even greater in week 3, so much so I'm concerned I'm not eating enough (very novel experience 😅). My side effects have been minimal too and weight loss good (10lb in 3 weeks), so saw no reason to move up yet. But I do understand the advice to buy 5mg and dose lower , and I debated this, but for ease just went for 2.5mg.

shrinkingthiswinter · 24/03/2025 08:46

About 8 or 9 weeks on 2.5 then a few on 3.75, now 5. Food noise disappeared instantly for me, plus I immediately had less joint pain. I feel hungry as meal times approach, but am satisfied with much smaller meals (with plenty of protein for fullness). I also sometimes feel hungry at bedtime, but not by the morning. 17.5 kg off in 15 weeks.

I am going to stay on 2.5 for a second month. I get pretty good suppression while still needing to make healthy choices. This feels like a good balance to me

Julesni77 · 24/03/2025 09:54

I found 2.5mg better than 5mg personally but everyone is different! I have done 2 2.5mg pens and 2 5 mg pens about to move up to 7.5mg

2 stone in 16 weeks so not super fast losses - the first 12 pounds was in t first 2 weeks of 2.5!

Hi, I'm just wondering how do you do the 3mg doses is it agreed with the place you're buying it from that you'll order 5mg pens and keep them for longer as you're using less liquid per dose?
I'm only asking because I know if you have a pen for too long they'll see it as a break and then want to bump you back down to 2.5mg

I've just been on 2.5mg for 4 weeks and I've got my 5mg in the fridge ready but I'm tempted to take half doses (30 clicks) or go up to around 3/3.5mg when I feel I need it as the appetite suppression is working extremely well for me at the moment.

This is my experience…..

I Am using a 5mg pen but taking smaller doses. I am currently taking 6 or 7 doses out of each pen. I keep pen in fridge at all times.

I am ordering new pen every 4 weeks.

Ahh right ok I understand thanks for your reply.

I'm very new to this and I'm just amazed at how strong and immediately I started feeling the 2.5mg so I don't want to unnecessarily just keep increasing my doses if its already working and then there's also the money saving aspect of partial dosing too.
