5mg to 7.5mg but using the same pen? A silly question?

I’m on my third month of 5mg but in this past week it’s started to become less effective - I’m suddenly so hungry!!

I’ve ordered a 7.5mg pen but I don’t want to waste the last 2 jabs in my current 5mg pen.
It seems like a silly question but later this week. is it ok to inject 5mg from current pen and then immediately do a second injection (counting clicks) of 2.5mg to make it up to 7.5mg? After that point I’ll use the new 7.5mg pen when it arrives.

When my dose wore off, my prescriber told me to take it every 5 days which really helped bring suppression and satiety back. You can count clicks instead if you prefer, as you've said take a full dose then count 30 clicks for the half. You will also have the bonus or golden dose which is more than a full dose usually.

Thanks! I just read online that it’s not advisable to take two jabs straight after the other. I really don’t see why! It might be one of those areas where it’s not been specifically tested but who knows.

I've always done it that way, can't imagine what the problem would be. New needle with each injection so how could it be problematic?

Where did you read that? Plenty of people do it, I have done it before myself once too. You can take it more frequently, every 5 days which is what prescribers advise, or the info leaflet states you can take it every 4 days if needed. Take a whole dose then top it up. I've split doses and taken one then another half way through the week.

Thanks everyone! I ran two searches through AI and both said ‘it’s not advisable’ but then AI is really only capable of parroting what the manufacturers say. There’s no logical reason why it should be a problem.

I actually didn’t know you could take it every 5 days. I’ll still jump to 7.5mg (as it’s due to arrive this week) but it’s good to know there’s other options. I’ve felt so well on 5mg but this last week, I’ve just really wanted to snack all the time. I made sure to drink lots and keep my protein high but it was like ‘old me’ was coming back and I really haven’t liked it. Will see how I fare on 7.5mg.
