Hi! I was told that ob/gyns often give it to their patients when they're nearing labor so they won't be forced to have a c-section if there is a flare up. All the ob/gyns I've spoken to about it, three in all, said they use it all the time. If your doctor said it's fine then you should try it. I do understand being cautious about taking medicine while pregnant though!
ok well i was told not to take it when pregnant i used this before i feel pregnant and when i when there when i had an outbreak she told me there isnt anything i can safely take because i was pregnant they still go away just takes a bit more time thats all so thats what i do when i get a sore now
I've never personally had a need for it, but I do know that it's safe to use. It's a Class B drug, which means it doesn't appear to cause adverse affects in pregnant animal studies. You should of course never take anything without speaking to your doctor first, but if he said it's fine then you should be ok.
