I started using Efudex yesterday and reading previous discussion I see that alot of people use this cream for 14 days. My dermatologist told me to use for 28 days (just on the right side of my nose) so I am concerned that it is too long. He also prescribed Taro-Mupirocin ointment and Cortoderm cream (to be used as needed). Has anyone else use any of these creams.
