Hello,
This is my promised follow up on my treatment with Carac and Efudex. I completed 32 days total. 22 days of once a day Carac and 10 days 2x per day Efudex. I have been told to stop treatment for now. The Efudex did not seem to have a more harsh effect on MY skin. The doctor said in perhaps 5 percent of the cases he has treated it is more potent. I returned for my follow up and because no new spots had surfaced and the old place were simply scaly, I was told to see the doctor again in Sept. He does not know at present whether my mild response was able to eradicate any of the kerotoses or not. I will wait to see when the red dots fade as to what is underneath.. All in all, unless I have trouble resuming normal coloring, I would definitely give Carac a go again if needed. I much prefered the one a day option so that I could wash my face in the am upon awkening. Efudex was greasier and even more expensive.
I also treated a part of my chest and got very different results there. Turns out I was more sensitive on my chest and my precancerous places got really red, sore and desirably yucky.
Take note that I am a very fair skinned, blue eyed blond who could not even tolerate Retin A because of irritation. I also have to use hypo allegenic products. But Carac and Efudex felt very mild to me. Not nearly as irritating as the Retin A. Go figure.
