What is 5-fluorouracil (Efudix)?
Efudix cream is a prescribed cream that contains 5-fluorouracil as the active ingredient. It is used to treat precancerous skin lesions such as sun spots (actinic keratosis) and Bowen’s disease (squamous cell carcinoma-in-situ). Efudix belongs to a group of anti-cancer medications.
Efudix preferentially targets precancerous skin cells that multiply more quickly compared to normal skin cells. It is effective in detecting and treating precancerous changes on the skin that may not even be noticeable by the naked eye.
When Efudix is applied, it is expected that the areas with the precancerous cells will “light up” while the normal skin will not. During treatment, the skin will start to become red, inflamed, weepy, swollen and crusted. This is considered a normal response as it indicates the Efudix is working to eliminate the precancerous cells. Within 7 days of treatment, redness of the treated area is to be expected. By day 14, the response will likely be at its peak and can resemble a bad sunburn . Eventually, the skin heals, leaving some residual redness that improves over the next few months after treatment has finished.
