Erbitux is indicated for the treatment of certain types of metastatic colorectal cancer and squamous cell carcinoma of the head and neck. It may be used alone or in combination with other cancer therapies depending on the specific diagnosis and treatment plan determined by an oncologist.
Erbitux is a targeted therapy that binds specifically to the epidermal growth factor receptor (EGFR) on the surface of cancer cells. By blocking EGFR, it inhibits the signals that promote cancer cell growth, division, and survival, helping to control tumor progression.
Erbitux is administered by intravenous infusion in a clinical setting. Common side effects may include skin reactions, fatigue, nausea, and electrolyte imbalances. Patients should inform their healthcare provider of any allergies or infusion reactions. Regular monitoring and dermatological assessments may be needed during treatment. This medication should only be used under the supervision of an oncologist.
