I recently went to the hospital to check on my baby the nurse said I had a UTI and gave me nitrofurantoin microcrystals to take for 5 days and the UTI will go away .. Is this medicine bad for the baby ? Can it affect the baby in anyway ? I'm really concern bc the doctor never came back to see me and the nurse didn't even know the doctor didn't tell me I had a UTI , although it was the emergency room so I'm sure she had different customers .. Any suggestions ?
