There a few other drugs you can try (if you have not already tried them)....Zovirax, Valtrex and Famvir. -and then there is Abreva (over the counter)
Some say the amino acid L-lysine works (which you have tried). Click here for a FULL list of "home remedies" for cold sores.
As far as prevention, there are a few things you can do.... use sunscreen on your lips and facial area, take a calcium supplement, avoid undue stress (hard to do sometimes), get plenty of sleep, and know that colds, flu and other sickness will precipitate an outbreak.
The over the counter products will work sometimes but they work slowly and sometimes not very well if the cold sore is large and has been there a while or if they reoccur as yours do.
The absolute best thing is Valtrex (prescription) for cold sores. You take 2000mg on day one then repeat in 2 days if the cold sore is not any better. That's it...no long complicated process.
