5-Fluorouracil Injection is a chemotherapy medication used to treat various types of cancer. It works by interfering with the growth of cancer cells, which are eventually destroyed.

What is 5-Fluorouracil?

5-Fluorouracil (5-FU) is an antimetabolite and pyrimidine analog. It inhibits the synthesis of DNA and RNA, which is essential for the growth and division of cancer cells. By interfering with these processes, 5-FU helps to stop the spread of cancer.


5-Fluorouracil Injection is indicated for the treatment of:
– Colorectal cancer
– Breast cancer
– Stomach cancer
– Pancreatic cancer
– Head and neck cancers
– Cervical cancer

Dosage and Administration

Dosage: The dosage of 5-Fluorouracil varies depending on the type and stage of cancer, the patient’s overall health, and response to therapy. It is typically administered in cycles with specific dosages and intervals.

Administration: 5-Fluorouracil is administered intravenously (IV) by a healthcare professional. The infusion duration and frequency will be determined by the oncologist based on the treatment regimen.

How 5-Fluorouracil Works

5-Fluorouracil works by inhibiting the enzyme thymidylate synthase, which is necessary for DNA synthesis. This inhibition leads to a shortage of thymidine, one of the building blocks of DNA, resulting in cell death. Since cancer cells divide rapidly, they are more susceptible to the effects of 5-FU.

Side Effects and Precautions

Common Side Effects:

– Nausea
– Vomiting
– Diarrhea
– Mouth sores
– Loss of appetite
– Fatigue

Serious Adverse Reactions:

– Severe allergic reactions
