Question: can efudex be used on warts?
Answer: The agent 5-fluorouracil is chemotherapeutic and is FDA-approved for actinic keratoses and basal cell carcinomas. 2 However, there has been a great deal of interest in its off-label use for the HPV virus. We typically use Efudex in our treatment course for warts as it is has 10 times the strength of Carac cream.
