Taking metronidazole and white creamy discharge is normal?
Yes and No
If you were prescribed this medication for bacterial vaginosis (bv) and your original symptoms have improved but now experiencing a white creamy discharge, then you may have a yeast infection due to this antibiotic wiping out its competitors by ridding you of bacteria.
In this case it would be a normal effect of the medicine. If not, then you still need to see your doctor to confirm.
