I have done some internet research on this & talked about it with my GP. Both said that because there is very little research about the safety of menthol during pregnancy, you should avoid throat lozenges with menthol in them (which rules most out - butter menthols, soothers, vicks vapodrops, anticol).

I have been sucking on eucalyptus & honey drops (because the amount of eucalyptus in them is so low anyway!!). But I'm not sure if they are really much better??
