Just a second.  Because the physician does not know, he tells the mother
"just to go to the bottle"?  Excuse me, but I always learned in
pharmacology, "don't prescribe medications the effects of which you
don't know".

Now, I have never heard of this "Xalatan".  It does not exist in Canada
under that name.  But the amount of medication in an eyedrop is very
little.  The mother's blood concentration should be extremely low, and
the amount that gets into the milk would thus be low.

Is this the *only* medication which can be used for this mother?  If
not, why not try something else first.  There are likely other
medications, older ones, which might work perfectly well, and we would
have enough information about to be able to say they are definitely
compatible with breastfeeding.

If you can find out the generic name, I might be able to get more info.
Check with Frank Nice.  He may have some info.
