I noticed you are in perth. King edward has a great drug information in pregnancy phone line. Thier pharmacists are really knowledgeable about drugs in pregnancy and during breastfeeding.
Recently we had some 'wormy' issues and when i went to the chemist I was informed that there are 2 formulations of combantrin. When I told the lady I was BFing they recommended a particular one, so I'd def recommend getting in touch with one of the major hospital pharmacies to check.
