Breastfeeding: Safety unknown; no information is available on the use of propantheline during breastfeeding. As propantheline is a quaternary ammonium compound, it is not likely to be absorbed and reach the bloodstream of the infant. Long-term use of propantheline might reduce milk production or milk letdown; observe for signs of decreased lactation-insatiety, poor weight gain.
