Efudex (fluorouracil) script for face and forehead, twice per day for two or three weeks. when do i know to stop applying ? can i use aquafor during application?

Try 3! Stop w/pain.: Efudex (fluorouracil) targets pre-cancerous skin lesions for destruction. It is common to experience redness, irritation and erosions with use, particularly at the pre-cancerous sites. Generally speaking, 3 weeks is the recommended course unless the pain from use is severe. Moisturizers are helpful but aquafor has lanolin which may cause an allergic reaction itself. Try vaseline if you experience this.
