Answer by DrLact: About Pyridium usage in lactation

The safety of phenazopyridine 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.
