Can I take Elmiron while I am pregnant or breast-feeding?
If you are considering getting pregnant or are pregnant or breast-feeding it is best to consult your doctor before continuing on Elmiron. While no birth defects have been seen in humans who take Elmiron, animal studies have shown Elmiron (pentosan) may pose a risk to the fetus. It is not yet known if Elmiron is excreted through the breast milk, however most medications do (in small amounts) pass through the milk and into the baby’s system.
