You should double check with your GP or OB just to make sure Abreva is okay. Just be careful not to touch it and spread the virus...the cold sore virus (herpes simplex) is very contagious.
It's not giong to affect your baby. I get them all the time. My ob saw one last time and never said a word, just gave me the antibiotics I needed for the accompanying chest infection I had.
My son gets them HORRIBLY and he was prescribed a topical cream to be used on his, I asked my ob about having it on my hands and he said it was fine to use.
they dont yet know if abreva is safe during pregnancy because it has only been tested on animals. so they label it a category B.
i highly doubt its safer to take antibiotics.... i used to get them a lot when i was younger.... and i think once when i was prego, i didnt even THINK to ask my doc or anybody whether or not its safe to use cold sore topicals.
Oh, perfect, I wasn't sure if it was ok to take topicals or not! Thanks!
