How can i best take care of cold sores?

Best RX is 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.

Oral Rx: If you start an oral medication like Valtrex (valacyclovir) at the first sign of an outbreak, you can significantly shorted its duration. The medication is cheap and very well tolerated. Topical antiviral medications cost far more and are far less effective (i think they are a waste of time and money and seldom prescribe them).

Your dr can: prescribe valtrex (valacyclovir). Melissa Officinalis or lemon balm (cream) has been shown in European studies to help expedite cold sore healing. It can reduce healing time by 1/2. Studies also show regular use can help v recurrences. Brief supplementation w lysine 1,000mg orally 3x a day at the onset, can hasten healing. Your dermatologist can provide laser treatments.
