Fluorouracil works by interfering with the growth of abnormal skin cells that contribute to pre-cancerous conditions. It is primarily indicated for the treatment of actinic keratosis and superficial basal cell carcinomas. This active ingredient is used in specialized generic topical treatments. Our pharmacy provides reliable access to medications containing Fluorouracil, supporting patients in the management of specific dermatological oncological conditions.
Fluorouracil belongs to a class of medicines known as antimetabolites. It is used mainly to stop the growth of abnormal skin cells. In the United Kingdom, you will find fluorouracil as the active ingredient in products such as Efudex and the generic cream labelled simply Fluorouracil.
Both Efudex and the generic Fluorouracil cream contain the same active substance. They are supplied as a topical cream, usually in a 5 % concentration, that patients apply directly to the skin. The two products differ mainly in branding and packaging; the strength and method of use are the same. Both are prescription-only medicines in the UK and are dispensed through pharmacies.
Fluorouracil works by interfering with the DNA building blocks that fast-growing skin cells need, allowing the abnormal cells to die off while normal skin gradually recovers.
When applied to the skin, fluorouracil is absorbed into the affected cells. It blocks the production of thymidine, a component required for DNA synthesis. Without thymidine, the abnormal cells cannot multiply and eventually break down. This process usually begins within a few days of starting treatment, leading to visible changes in the treated area.
These reactions are generally temporary and indicate that the medication is having its intended effect. They usually lessen once treatment finishes.
If any of these occur, seek immediate medical assistance.

Remember that each product-Efudex and the generic Fluorouracil cream-may have slightly different instructions for use, so always follow the guidance that comes with your specific medication. For detailed usage, dosing, administration, refer to your specific medication's information.
