No information is available on the clinical use of dexmethylphenidate during breastfeeding; however, the manufacturer estimates that a fully breastfed infant would receive a relative dose of 0.2 to 0.7% of the maternal weight adjusted dose. Dexmethylphenidate is an isomer of methylphenidate. Methylphenidate levels in milk are low and not detectable in the serum of a few breastfed infants. If dexmethylphenidate is required by the mother, it is not a reason to discontinue breastfeeding.[1] It is possible that large dosages of dexmethylphenidate might interfere with milk production, especially in women whose lactation is not well established.
