Splitting the dose?

Hi all,

I've been on mounjaro now for 12 weeks at 2.5mg. I'm not getting anywhere near the same level of suppression, and my food noise is starting to come back. I want to move up to the 5mg, but I've already received my next 2.5mg pen (and jab day is tomorrow so I don't have time to get the 5mg).

So, do I a) split the dose so 2.5mg tomorrow, then another 2.5mg after 72 hours.
b) Do 2.5mg + count clicks for 1.25mg, so I can build myself up to 5mg (as I'm bloody terrified of the 5mg side effects Grin)
or c) pull up my big girl pants, take the 2.5mg, and pray for some willpower.

Has anyone ever done half doses or splitting of doses, and if so how did you get on with it?

Right now I'm leaning towards option C because I'm a wuss and I'm loathe to deviate from prescribed usage.

Thanks.

Why have you stayed on 2.5 for 12 weeks? If you can afford it, I would just go up to 5mg by taking 2 x doses from the 2.5 pen and order a 5mg pen asap.

I stayed on the 2.5 because it was working for me. I was getting good suppression, no food noise, and lost 2 stone. Do you think it would be OK to take 2 doses on the same day?

Are you losing weight on the 2.5? If so, how much?

I have had a bit of food noise back but I am still losing 1.5-2lb/week so have decided that 2.5 works for me for the time being.

I started noticing about 3 weeks ago that the food noise was coming back. For 2 weeks I lost nothing (lost 1lb then gained it back the next week). This week I've lost 2.6 lbs, but I think that's because I've been away and haven't been able to sit and raid the fridge Grin

Sound sensible to move up. I think I would go for option b if it were me.

Why people don't use these drugs as directed is beyond me! So much self medicating and changing of the advice given, it's no wonder people start having problems.

I've never not taken the medication as directed. I was asking if anyone had any experience of it.

Yes absolutely, it's just the same as taking 5mg, but you'll have to do it in 2 injections

I have taken 2.5mg for 10 weeks
then 3mg for 5 weeks and 3.5mg for 5 weeks
then I got a rash as a side effect and had to go back down to 2.5mg as the itch was unbearable. Tomorrow I am going up to 3mg.
i have lost 41lbs
