Methscopolamine Bromide Levels and Effects while Breastfeeding
Summary of Use during Lactation
No information is available on the use of methscopolamine bromide during breastfeeding. Because methscopolamine bromide is a quaternary ammonium compound, it is not likely to be absorbed and reach the bloodstream of the infant. Long-term use of methscopolamine bromide might reduce milk production or milk letdown, but a single dose is unlikely to interfere with breastfeeding. During long-term use, observe for signs of decreased lactation (e.g., insatiety, poor weight gain).
To substantially diminish the amount of drug that reaches the breastmilk after using eye drops, place pressure over the tear duct by the corner of the eye for 1 minute or more, then remove the excess solution with an absorbent tissue.

Effects on Lactation and Breastmilk
Relevant published information in nursing mothers was not found as of the revision date. Anticholinergics can inhibit lactation in animals, apparently by inhibiting growth hormone and oxytocin secretion.[1-5] Anticholinergic drugs can also reduce serum prolactin in nonnursing women. The prolactin level in a mother with established lactation may not affect her ability to breastfeed.
