Hey thanks for your faith in the health care Magic I have gone through your question and I understood your problem. Tab niftran consists of nitrofurantoin. Nitrofurantoin is pregnancy category B. It is one of the few drugs commonly used in pregnancy to treat UTIs. The drug should not be given to women in late pregnancy due to the potential risk of hemolytic anemia in the newborn, as the newborn has not yet developed the enzymatic pathways necessary for glutathione metabolism and the drug may cause oxidative damage to the red blood cells. Thank you.
