Fluorouracil

Health and Nutrition > Medicines > F

Health Centres - Fluorouracil



How does it work?

Fluorouracil is one of a group of anti-cancer medicines called 'cytotoxic antimetabolites'. Cancers form when some cells within the body multiply uncontrollably and abnormally. These cells then spread and destroy nearby tissues. Fluorouracil acts by slowing this process down. It kills cancer cells by attaching to a chemical within the cell and preventing it from using vital nutrients and other substances necessary for normal activity. Unfortunately, fluorouracil also affects normal, healthy cells and therefore it produces serious side-effects during long-term treatment. The most important side effect is in the bone marrow where blood cells are made. Regular blood tests may therefore be needed to prevent the damage becoming permanent. Fluorouracil can be given by mouth either as capsules or the solution mixed in with fruit juice. It can also be given by injection or slow infusion into the veins (intravenously).
