Can you please tell me fastest most effective ways to get rid of cold sores?

Depends on Stage: Cold sores occur in three main stages: prodromal, blistering, and healing. The prodromal stage is the only stage where they can really be "treated"--this is when the area where the cold sores will arise becomes tingly and/or itchy. Application of an anti-viral ointment (like abreva) may prevent or lessen the outbreak. Once the area blisters, it is too late--just keep it moist until it heals.

Tincture of TIME: The lesion undergoes a series of changes and heals over 14-21 days--after which the virus goes dormant. Anti-viral drugs based on Acyclovir are available by prescription and can be taken as a preventive med. Otc meds, like abreva, have variable success rates. If they occur frequently, you can take Valtrex (valacyclovir) daily as a preventive measure, but will need a prescription. There is no 'fast' way.
