Aloha, I have checked the archives but found no information on this medication. Mom just started taking (most likely temporary for vertigo). She is nursing a one year old. Mom has not stopped nursing while on medication, but is concerned since her doctor could give her no info---other than to not breastfeed. According to Hale's 98-99edition, no data is available on secretion of this drug into breastmilk. It has a high molecular weight, so wouldn't that mean little would be secreted into breastmilk? Does anyone have any more information on this drug or an alternative? Thanks. Aloha, Gloria Thai Honolulu, O'ahu, Hawai'i located 20 degrees North of the Equator
