Personally, I don’t see how you could. It seems logical to me that any pharmaceutical is going to kick the shit out of anything natural (obviously that doesn’t apply to everything, but I think in this situation it does).
I could be wrong, but that’s just what I think.
It might not be a super broad-spectrum antibiotic and you might be fine.
In any case - you obviously need the antibiotics so just take the hit on your gut health and repair it as quickly as possible once you’re off.
