Dear Laura, It says do not use  cisapride[propulsid] with ketoconazole,
itraconazole, miconazole in the PDR under contraindications for cisapride.
Diflucan is also an -azole. I don't think it could be plainer and I for one
wouldn't want to try it especially as Dr. Jack says -there is something
safer, cheaper and tried and true to use [gentian violet].  Sometimes we
make fun of the PDR and all they have to say about nursing mothers, however
that is NOT the issue here.  Sincerely, Pat in SNJ
