Docosanol.: Abreva contains docosanol which is reported to prevent the herpes simplex virus from penetrating the membranes of your cells. I am hoping some other physicians who prescribe this produce can comment on effectiveness.

Yes But: Do not play with it or it will get bigger, do anything that makes you comfortable. It takes about 2 weeks to go away no matter what you seem to do. However check with your pharmacy for a few items that may make you more comfortable - remember that they generally do not shorten the 2 week time.
