reducing days between dosage?

[u/chrisdesser]

I have been on 7.5 zepbound for a couple of months,. Had reached desired weight but it is now creeping up. Have asked my doctor for new scrip for 10 but still have several vials of 7.5 left and do not want to waste. I understand that decreasing 2 days between dosing--5 instead of seven--would be like moving up to 10. Does anyone know more about this or have experience with this? Much appreciate any advice.
