I stopped using Efudex on my lips Oct 5,2022. The Efudex did clear up potential cancerous cells on my lips. Since then I have had severe reactions with my lips and cheeks continuously peeling and very red. Four months later my lips are still swollen and red. I am Unable to eat anything spicy or tart or peppery. I use zinc and Vaseline on my lips to alleviate the pain. Has anyone else had this type of reaction?
