when do you decide?

when does a person decide if a drug they are taking is doing anything?
ive been taking ozempic 1 mg for nearly a year (begun at lower doses)
and the only thing thats happened is a worsening a1c
from 6.6 to 6.8
i dont want to blame the medication but my original
reason for trying it was to lower the amount of insulin
i use which hasnt happened
do i continue to risk side effects for what seems like
no benefits?
what would you consider in deciding to continue?
