I have never heard of this medication, but let's look at the
information.

There are two real issues about drugs during pregnancy.  One is that
*any* contact with the baby is likely to cause some problem.  In this
case, where we are concerned about central nervous system effects, the
drug should be safer during breastfeeding than during pregnancy, because
the baby would be exposed during a less sensitive time and in smaller
quantities.

Not all drugs are safe during breastfeeding just because they are safe
during pregnancy (although almost all drugs are safe, nevertheless,
during breastfeeding).  During pregnancy, the mother metabolizes the
drug for the baby; after, the baby is on his own.
