FOLFOX is a chemotherapy regimen commonly used to treat certain types of cancer, particularly colorectal cancer. The name stands for a combination of three drugs: Folinic acid, Fluorouracil, and Oxaliplatin. These medications work together to slow down or stop the growth of cancer cells in the body. The treatment is typically administered through an intravenous (IV) infusion in a hospital or clinic setting. Patients may receive FOLFOX in cycles, with periods of treatment followed by rest to allow the body to recover. Side effects can include nausea, fatigue, and changes in blood counts, which are monitored by healthcare providers.
