Fess Nasal spray is safe in pregnancy. However Vicks is not safe in pregnancy. If you look up "Mothersafe" on the web there is a toll free number doesnt matter if you are not in NSW, call them and they can confirm what is safe and what is not, this organisation is part of Royal Randwick for women from what I remember. When I am sick I have been told I can only use panadol and I can use Difflam losenges.
