Can I use schederma for cold sore

I would not use anything on a cold sore. Cold sores will go away in about seven days and all you really need to do is reduce the pain caused by them.

Abreva is great for cold sores. I haven't heard of Schederma, but that sounds like a skin product.

I've used Abreva whenever I've had a cold sore and it seems to reduce the number of days that the cold sore is painful and huge.

Good luck! Those things hurt!
