Fluorouracil is one of the more common antimetabolites that has a role in treating tumors and is also used in dermatology to treat some warts. Removal of warts with fluorouracil over a few days will depend on the size and extent of the warts and can take anywhere from 1 month to several months. Usually, smaller warts can be seen in 2-3 weeks and can be cured within 1 month. For those who have a wide range of warts or severe symptoms, the treatment time needs to be extended, possibly between 1-2 months or even up to 3-4 months, and the medication should be used regularly during the treatment period to enhance compliance to ensure the efficacy. Fluorouracil is available in ointment and injection formulations, both of which can be used for anti-infection treatment of the skin. For skin conditions such as common warts and plantar warts, topical fluorouracil ointment can be used for treatment, but it is prone to recurrence and pigmentation. The fluorouracil injection can act directly on the wart, which can cause blockage of the wart blood vessels, resulting in blocked nutrition of the wart, and fluorouracil is a pyrimidine antimetabolite, which can interfere with and block DNA synthesis, destroy the reproduction of the virus, and eventually cause the wart to fall off. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things.
