These medicines may be absorbed into the body. Atropine passes into the breast milk in very small amounts and may cause side effects, such as fast pulse, fever, or dry skin, in babies of nursing mothers using ophthalmic atropine. It is not known whether homatropine or scopolamine passes into breast milk. Although most medicines pass into breast milk in small amounts, many of them may be used safely while breast-feeding. Mothers who are using one of these medicines and who wish to breast-feed should discuss this with their doctor.
