Help with pen dosage

9 replies

dancemom · 26/03/2025 16:12

So I’m on week 4 and have had great suppression with 2.5mg so I ordered and received another 2.5mg pen intending to stick with this dosage.

however yesterday I felt snacky for the first time and today the food noise has returned.

is there any way to use my 2.5mg pen to give a 3.75mg or even 5mg dosage?

does the 2.5mg and 5mg refer to strength of the dosage or volume?

can anyone advise?

If it was only yesterday and today I would ride it out for at least a week or two before messing around with doses. Relax and try not to think about it too much.

I have been on 3.75mg (from a 5mg pen) for 38 weeks and it is completely normal to have the odd day or even week where suppression dips significantly, then it will kick back in. Your body will sometimes crave food because it is short of nutrients, feed it (healthily!)

@WeAllHaveWings talks sense on this. Don't forget the levels in your system will build with each injection, so I would see how you get on rather than move to a different dose immediately.

Just for information, each injection from the pen is 0.6ml in volume, regardless of the dose of the pen. The mg measurement is the strength, so the amount of medication, in mg, that you get in that 0.6ml volume.

Can I ask, how many clicks is it for 3.75? I have a 5mg pen ready to go but feel like 2.5mg is almost but not quite enough. I think I may go for 3.75mg instead.

I googled it - it’s 45 clicks, 15 clicks per 1.25mg in a 5mg pen.

Dose required divided by pen dosage x 60 = clicks

3.75 / 5 x 60 = 45 clicks

lovealongbath · 26/03/2025 19:23

3.75 / 2.5 x 60 = 90 clicks

If your jab is due in next 2-3 days, its normal to feel hungrier as the half life is 5 days.

You were correct! Suppression returned to previous levels today. Also started my period so maybe that had something to do with it too 🤷🏻‍♀️

Thank you all

It’s not meant to kill your appetite dead. I’d stick to the lower dose:
