Vemurafenib (vemurafenib) — Uses, Dosage, Side Effects & Safety

Drug class: BRAF kinase inhibitor (antineoplastic agent)

Overview

Vemurafenib is a prescription medicine used to treat certain types of skin cancer called melanoma that have spread to other parts of the body or cannot be removed by surgery. It is specifically used in patients whose cancer cells have a mutation in the BRAF gene (BRAF V600E mutation). This medication works by blocking the activity of the abnormal BRAF protein, which helps slow or stop the growth of cancer cells. Patients should know that vemurafenib is only effective in cancers with the BRAF V600E mutation, so genetic testing is required before starting treatment. It is taken by mouth as a tablet, usually twice daily. Regular monitoring and follow-up with your healthcare provider are important to check for side effects and ensure the medication is working as intended.
