For patients and families

What is Flurosol 500mg?

Flurosol 500mg is a 10 ml vial of fluorouracil, also written as 5-FU, made in Pakistan by Pharmasol. It belongs to the antimetabolite group of chemotherapy medicines. Cancer cells mistake it for a building block they need to copy their DNA, and that error stops them from multiplying.

What is it used for?

Fluorouracil has a long record in cancer care. Doctors use it for:

• Bowel (colorectal) cancer: after surgery and for cancer that has spread.
• Breast cancer: as part of combination chemotherapy.
• Stomach cancer: for advanced disease, with other drugs.
• Pancreatic cancer: in selected regimens.
• Head and neck cancer: together with other chemotherapy.

Your oncologist picks the combination that fits your cancer type and stage.

How is it given?

Flurosol 500mg goes into a vein. In some regimens a nurse gives a quick injection or a short drip, and in others a small pump delivers the medicine slowly over about two days while you go home. Your doctor decides the dose, which depends on your regimen, body size and blood tests. Before treatment starts, ask your doctor whether a test for DPD enzyme deficiency suits you, since low levels can cause severe reactions.

Common side effects

• Mouth sores and a sore throat
• Diarrhoea, nausea or vomiting
• Red, peeling or tender palms and soles
• Tiredness and lower blood counts
• Sensitive skin that burns easily in the sun

Tell your care team straight away if you have a fever, severe or bloody diarrhoea, mouth sores that stop you eating, chest pain, or confusion.

Storage

Keep the vial below 25°C, away from light, in its carton. Do not put it in the fridge, because the liquid can form crystals when it gets too cold.
