Hi, my experience ... I just had the worst cold sore outbrake in my life! After coming from a short vacation, I developed 3 cold sores on my lower lip and then a couple of days later a fourth one on the other lip. It was extremely painful, looked absolutely horrible and I took 2 weeks to heal. My doctor prescribed meds, but I've never taken them before so was reluctant and didn't start. However, I may start it if something like this happens again-- 3 doctors and a pharmacist said the meds are safe during pregnancy.
