RT Journal Article SR Electronic T1 Is it safe to breastfeed while taking methylphenidate? JF Canadian Family Physician JO Can Fam Physician FD The College of Family Physicians of Canada SP 765 OP 766 VO 61 IS 9 A1 Maria Marchese A1 Gideon Koren A1 Pina Bozzo YR 2015 UL http://www.cfp.ca/content/61/9/765.abstract AB Question My patient has narcolepsy and is currently breastfeeding her 3-month-old infant. Lately she has had difficulties adjusting to caring for her baby, especially staying alert with the demands of breastfeeding. If she starts taking methylphenidate again, should I advise her to switch to formula?Answer Methylphenidate is excreted in breast milk only in small amounts, and to date there have been no reports of breastfed infants demonstrating any adverse effects. Based on the available data, methylphenidate appears to be compatible with breastfeeding; however, the long-term neurodevelopmental effects have not been adequately studied.
