Head-to-head comparisons of medication uses, side effects, warnings, and more.
Key takeaways
Fluorouracil (Efudex) and ingenol mebutate (Picato) are both topical medications used to treat actinic keratosis, a skin condition caused by sun exposure. However, they differ in several ways. Fluorouracil is an antimetabolite available as a cream or solution, and it is also FDA-approved to treat basal cell carcinoma, a type of skin cancer. Ingenol mebutate (Picato), on the other hand, was a gel that has been discontinued in the United States due to its potential to increase the risk of skin cancer. Fluorouracil is applied twice daily for 2 to 6 weeks and can cause side effects like skin burning and irritation. Additionally, fluorouracil is not safe for use during pregnancy and requires careful application to avoid affecting healthy skin.

But only fluorouracil 5% is approved to treat basal cell carcinoma, a type of skin cancer. Fluorouracil (Efudex) topical is applied directly on the affected area(s) twice daily for 2 to 6 weeks, depending on what condition you're being treated for. Side effects of this medication can include skin burning, crusting, and irritation.
