Half dosing?

I've already emailed this question in to my provider, but was just curious as to general opinion on this.
I'm currently on 2.5 of mj and have had not had any side effects at all, and already have some suppression and weight loss. I decided to go up to 5 and see how that is, and my first increased dose is on Friday. However I'm going on holiday on Friday for a long weekend, and I'm worried that the increase might trigger some side effects and I really don't want to spoil my time away. So my musings are: do I leave it longer before my first larger dose and take it Tuesday morning instead, or can I manipulate the dosage on the pen to have a 'half dose' of 2.5 for that week (as I know my body is used to that) then take the full 5 next Friday.
I'm leaning on the first option sounds safer, although going away without the help seems tougher than it needs to be lol. I guess I was just wondering if anyone had used the pens to give a half dose and is it in fact nowhere near as difficult as I think it is. (I have depression and I'm prone to over thinking everything ATM lol)

i thought you have to Increase the dose really slowly. 2.5mg to 5mg is a big jump.

Why increase the dosage at all if its working?

Desperatelydoomscrolling · 20/05/2025 13:12

Oh I haven't seen anything on increasing slowly, I'll recheck my emails in case I have missed some important instructions, like I say, mental health isn't the best ATM so maybe I have misunderstood.
As for why, although I have had some reduced food noise everything I read seemed to say that 2.5 was not a standard therapeutic dose and so I had planned to try this next step as I thought that was the normal treatment path tbh. I can just stay on 2.5 following this pen if I feel the 5 increases side effects or has no further effect on my weight loss and it will just take me a little longer to get to my goals, I'm ok with that.
If no one else has tried not taking a full dose on the pen then no worries, I'll just wait for my provider to reply to my email and probably just delay my dose. Sorry to butt in everyone, have a great week :-)

No, 2.5 to 5mg is not a "big jump", it is the normal increment (after at least 4 weeks on 2.5). I had no problems with that transition, but some people have. I have stayed on 5mg for months as I have been losing steadily and have had practically no side effects.

I am now taking 2.5 and 5mg doses out of my 5mg pen on alternating weeks (I am experimenting with decreasing dose as I near my goal). There is no problem doing that, the pen is still as accurate if you do a "half dose".

It's not a big jump, it's the standard jump of 2.5mg between dose levels - the next would be 5 up to 7.5 and so on. Moving from 2.5 to 5 after the initial month is also how the medication is intended to be used.
That said, OP I did two weeks on 3.75 when I moved up, as it coincided with Christmas and I wanted to avoid any bad side effects while I was staying with family.

I would be very surprised if your provider condones taking a partial dose from your 5mg pen, but mean people do.

30 clicks will give you a 2.5mg dose. 45 clicks a 3.75mg dose.

If you are getting good effects and don't want to risk unpleasant side effects on your holiday you can do a 2.5mg from your 5mg.

If you decide when you come back you want to increase to 5mg you can but make sure you do min 4 weeks on it before increasing again. You could do a 2.5mg then 4 x 5mg from the one pen, but you will need a syringe to extract the last dose.
