There is no limit for this virus; it can attack continuously any number of times. If you are facing a cold sore for the first time then you need to consult your doctor for advice. One common method to make the virus dormant is to use DMSO (Di methyl Sulf oxide). Dimethylsulfoxide is a very powerful medication for cold Sores as it kills the cells which cause the sore. The cold sore dies when these cells are killed and the virus becomes weak and dormant. Dimethylsulfoxide liquid has the ability to permeate living tissue. This gel is available in various concentrations. Generally it is recommended to use 70% concentrate cream (do contact your doctor about exact guidance). Results also have shown that people using DMSO had a quicker recovery than non-users. It is a potentially safe liquid and it is useful for recurrent herpes.

DMSO medication can be used in conjunction with other medications such as oral acyclovir. It is generally recommended that DMSO be used on alternate days or every other day. Please read the DMSO disclaimer and also take advice of your doctor before using these products.
