Cold Sore Scab

What do you do after a cold sore scabs up can you put some neosporin on it? Or leave it be? ?
I have this big scab over it and when I shower it tends to peal off. I've used so many home remedies to get rid of it and most have helped with the healing process.
I lost my abreva and don't want to spend $15 more on a new one if this one is almost gone!
Remember that the virus that causes those sores like injured tissue so each time you tug at the scab, it can cause the sore to last longer. Also keep in mind that the virus can get on your fingers and invade other areas of susceptible tissue such as your eyes, your nose, pimples, scratches, etc. Wash your hands well after touching them. At this point keeping the scab soft is important, it is past the stage where medicine will actually affect the lesion. Use neosporin (unless you are allergic to sulfa drugs) then use Bacitracin instead, or anything that will keep it soft.
If you get these frequently, talk to your dentist about a prescription pill that you can take the moment you feel a cold sore starting, you take it for 3 days and the sore barely becomes visible (if at all) and goes away right away... no scab, no mess. The RX is called Valtrex (yes it is the same medicine used for genital herpes but is used slightly differently). It works much differently and much more effectively than Abreva. Good luck!
