"go too far" -- suitable for academic writing?
"overcompensates" could be a good non-idiomatic substitute. Depending on the wider context (the stated goal of XXX, it's particular mechanisms of action) it may even be more or less accurate than another word choice.
So I just found this word, monosemous, which appears to be the direct opposite of ambiguous. Therefore, monosemous may just be the most monosemous way to express the idea you appear to be aiming for.
