Not for the primary cause of the sore.

Cold sores are caused by a viral infection, specifically, the herpes simplex virus. The active ingredient in foban cream is fusidic acid, which is a type of antibiotic. Antibiotics are only good against bacteria, not viruses.

However, there may be some evidence that it helps in the healing, in the same way that antibiotics helps in rhinovirus-initiated colds. It prevents secondary bacterial infections that may hinder the body's own natural healing process from the virally caused wound.

Hope this answers your question.
