  Dr Hale says: " at present, there is no data avalable on transer fo this
compound into bm. however, due to its small molecular weight adn other
kinetic data, one must assume that methylphenidate readily enters bm and
would be absorbed by the infat,. a prolonged release tablet formulation is
commonly used and would extend the half life. risk of toxicity must be
weighed against need of mother. "
