In brief: effective if early

Anri-virals work best if taken when prodrome like tingling occurs.
Or of frequent outbreaks then as daily preventative.

In brief: Very good

Valtrex (valacyclovir) is very effective for cold sores, although i typically prefer zovirax just because it's cheaper.

The earlier an antiviral is started, the more effective it is in reducing symptoms.
