Both the hippurate and mandelate salts of Methenaminum pass into milk in small quantities and appear acceptable to use, even while nursing a newborn.

Four newborn infants were allowed to breastfeed in one study after a maternal dose of 1 gram of Methenaminum hippurate. No adverse effects were reported.[1]
