Avoid Pyridium during pregnancy and breastfeeding. Phenazopyridine, the active ingredient in Pyridium, passes into breast milk and may reach the fetus. While studies haven’t definitively linked Pyridium to major birth defects, the potential risks outweigh the benefits, especially during the first trimester when fetal development is most critical.
Potential Risks
Limited research exists on Pyridium’s long-term effects on developing fetuses and infants. However, potential risks include interference with fetal development and adverse reactions in nursing infants. These could manifest as allergic reactions or other side effects. Therefore, safer alternatives are always preferred during pregnancy and breastfeeding.
Safe Alternatives
Consult your doctor or midwife immediately for UTI symptoms. They can prescribe a safer alternative, such as antibiotics specifically approved for use during pregnancy and lactation. Always disclose your pregnancy or breastfeeding status to any healthcare professional before taking any medication.
