Firstly Tegan, CONGRATULATIONS on your pregnancy. I must of missed the announcement ](*,)

I was told by my doctor NOT to use cold sore cream, because the main ingredient is Aciclovir, which is not meant to be taken whilst pregnant.

I have a "complete guide to medication" book at home and it says that Aciclovir has a B3 grading and should only be used if medically essential.

So I would just put up with it and not use the cream. I get them pretty bad and luckily have only had one during the pregnancy so far, but I just let it clear on it's own.

Trish actually said that tea tree oil works well. I will definately try that if another one arises.
