Betadine Cold Sore products are effective in all three
stages of a cold sore. Betadine Cold Sore products can help against the
infection, if applied in the prodromal stage. They can also help if applied
during the second stage. Betadine Cold Sore products can also help reduce the
spread of infection from one person to another or from one part of the body to
another. This is important because, until healed, the blisters and ulcers of a
cold sore are highly contagious.
