Instead of automatically saying gabapentin is contraindicated, why not do some studies of concentration in the milk? Maybe no studies have been done yet. I will bet the neurologist and pediatrician are just assuming this drug is contraindicated. The information I have (I don't have a lot though) shows oral bioavailability to be relatively low (59%), and plasma levels ranging from 1-10 microg/ml. If the m:p is 1, a premature baby getting 300 ml/day would 100-1000 microg/day. This seems quite low to me. Jack Newman, MD, FRCPC
