If you checked Dr. Hale's book you should have the information to state with
confidence that there should be no problem breastfeeding with imitrex.  The
reason it's given by injection is that it is so poorly absorbed from the
gut.  The baby won't be getting it by injection, will he?  How many ob's
does it take to screw in a lightbulb?  Two, one to hold the forceps and the
other to tell him which way is up.  (Stupid, but I can't think of anything
better).
