Hello, we found enterococcus in the seed at the end of the third trimester. The doctor prescribed Polyginax for 6 days of suppositories, but it contains the prohibited antibiotic neomycin which can cause hearing problems in the fetus, and is not recommended in the instructions. I am now worried about what will happen and what to do next. Another doctor said that if there were no complaints and symptoms, then treatment with enterococcus was unnecessary. Will Polyginax also negatively affect the fetus after 6 months of use?
