What formulation is Efudex (fluorouracil) provided in?

Efudex, known generically as fluorouracil, is provided in a cream formulation. This topical medication is primarily used for the treatment of skin conditions such as actinic keratosis and certain types of skin cancer. The cream is applied directly to the affected areas of the skin, allowing for targeted treatment that minimizes systemic exposure while effectively delivering the medication to the site where it is needed.

The choice of a cream formulation is particularly beneficial for conditions affecting the skin, as it allows for localized action, helping to reduce potential side effects that might arise from systemic absorption seen with injections or oral medications. This formulation is designed to penetrate the skin and exert its effects locally, promoting the destruction of abnormal skin cells without significant impact on surrounding healthy tissue.
