I did Efudex 5% 2x day for 21 days.
The first two weeks were not painful, but I began to get quite self consious of my bright red, tight face as those days went by. I used organic Coconut Oil from the natural food store for the first two weeks and it worked great (I avoided the Vaseline as long as possible).
The third week was very uncomfortable and I was glad that I had arranged to work from home. My whole lower face was swollen, bright red, painful, and itchy (my forhead had just a few spots). When the skin started eroding and weeping, it became uncomfortable enough that I kept it constantly covered in Vaseline. I took 2-3 200 mg Ibuprofen every four hours to keep the swelling and pain down. I slept with a towel on my pillow. I only wanted soft plain foods like rice or pasta. It was hard to open my mouth. I could not put water on my face at all as the stinging was too painful.
I did the three week Efudex treament, with a fourth week to heal from the effects of the chemo. I took the fourth week off from work, and felt too awful to even work from home. This was the worst week for me and I really had to focus on healing and sleeping. I did not want to do much else than watch DVD's or play computer games - (neither of these is normally a pastime of mine - but even reading books or magazines or emails or phone conversations were too hard to do.) This really was a week where the discomfort in the face really took priority in my awareness.
I stayed at my boyfriend's house for Week Three and let him nurture and care for me, and run errands. But Week Four I just wanted to hibernate by my self and so went to my own home. I felt worn out from the pain, and irritable. I looked and felt terrible. I just wanted to be alone. My mother and grandmother checked in on me, but they were the only people who saw me.
I stopped the treatment after 21 days. My face felt okay on Day 22. But Day 23 and 24 were the very worst of the whole experience. I was in pain, with my face swollen and weeping and stinging and itching and hurting. My whole face felt like a second degree burn. I kept slathering on the Vaseline, afraid to let it dry out even for a moment as the pain was intense. I was worried about infection as my whole face was a wound. So I used a lot of antibacterial ointment (petroleum base with no alcohol).
Day 26 I woke up and could tell healing had happened as my face did not sting anymore. For the first time in a couple of weeks, I could put my face under gentle shower stream. It felt awesome. And after that - My face healed faster than I can believe.
Today is one week after I stopped the Efudex, and my face is almost entirely clear. I have one place over my lips still to heal. But the rest of my skin looks better than I can remember it looking in my adult life. This was hell, but I have to say - the difference in the end is remarkable. It was a harder process than I expected, but I did survive it.
Other thoughts:
If you are single - stock up on groceries to last you for awhile as you will not want to go out in public for 1-2 weeks at the end. For the final weeks I only wanted soft bland food.
Get lots of water - I drank 2 liters a day to try to keep my face hydrated.
Be sure to stock up on clean towels and sheets as this is a messy process.
I cleaned my house while I still felt well. I did not want to anything in Week 4, and was grateful for a clean house to be sick in.
Plan on wearing clean soft clothes that don't matter if they got Vaseline on them.
I went through two rolls of papertowels on my face in one week. This is messy.
I took mega vitamins everyday. I also took Omega essential fatty acids because I heard that they are good for helping wounds to heal.
Buy Vaseline, antibiotic ointment, hydrocortisone creme, ibuprofen. I had no trouble sleeping but some people do, so consider sleep aids.
I could not tolerate anything on my skin made with alcohol in the base, such as the first antibiotic and hydrocoritsone cremes I used. This mistake was excrutiating.
I used generic brand tripple antibiotic ointment maximum strength in a petroleum base. I used this daily on open sores in the 4th week.
I used Vaseline and Triple Antibiotic creme when I was most uncomfortable. For the first two weeks I used Coconut Oil to keep my face moist with no stinging chemicals. The final week I used Vitamin E oil to help the healing.
I slept a much as I could at night. I felt worn out by the healing process. It was hard work.
