What is the best medication for cold sores - prescribed pills or over the counter cream? Which one and why?

Thanks!|||ZOVIRAX cream over the counter at chemists.It%26#039;s magic!|||Abreva works best but only if you apply it when the cold sore first starts to appear.... then keep applying it every two hours. The gel is better than the cream. It stays on better.





I%26#039;ve never tried pills. Sorry.
