Both methenamine and mandelic acid pass into milk in small quantities. Methenamine mandelate appears 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 methenamine hippurate. No adverse effects were reported.[1] Six infants were allowed to nurse during maternal ingestion of the large daily dosage of 12 grams of mandelic acid. There was no clinical or laboratory evidence of harm to the infants.[2]
