If you have any queries please ask your general practitioner or me.
As a general rule medical preparations that you can buy ‘over the counter’ (not on prescription) in a pharmacy or supermarket are safe to take in moderation in pregnancy.

I suggest you do not ask a pharmacist for advise. They are very cautious on the whole and usually scare you and advise you against taking almost any over the counter medication, even when you are very unwell. Pharmacists are there to full scripts not to play doctor.
Fluoride tablets are not normally required in Sydney. See the supplements section of this web site for more information.
