Skin Cance
"Used Efudex 7 years ago.  Now using Carac 0.5%.  Apparently the same dosage of Fluorouracil but in a different cream base.  My dermatologist said that the Carac seems to be less aggressive. Only use once a day versus twice with Efudex.  From my memory of Efudex, Carac seems much less raw so far.  Still have the redness and tenderness but much more tolerable.  One more week to go.  Not sure on cost.  Insurance covered it, luckily. (using tazarotine with Carac on scalp which helps absorption - skin is tougher)"
