Is methylphenidate something people stay on while nursing, according to guidance?

Guidance does not give a single yes or no on staying on methylphenidate while nursing. NHS information on methylphenidate in pregnancy, breastfeeding, and fertility treats the decision as individual. The Breastfeeding Network discusses methylphenidate among stimulants with relatively more breastfeeding data and still describes case-by-case care, including watching the infant. Pregnancy, breastfeeding, and fertility treatment can change the benefit-risk discussion, so medication changes need review with the clinicians involved rather than a forum-based plan.
