The safety of Phenazopyridinum [INN-Latin] is not established in infants or during breastfeeding. Because it can cause methemoglobinemia, sulfhemoglobinemia, and hemolytic anemia, it should be avoided while breastfeeding, especially with an infant under 1 month of age or with glucose-6-phosphate dehydrogenase (G6PD) deficiency.
