Uses

Cetuximab is used to treat a certain type of cancer of the colon (large intestine) or rectum. This medication is also used to treat head and neck cancer.

Cetuximab is a man-made protein (monoclonal antibody).

How to Use This Medication

Cetuximab is given by injection into a vein as directed by your doctor, usually once every week or every 2 weeks by a healthcare professional. Another drug (such as diphenhydramine) may be given before you receive cetuximab to lessen the chance of certain side effects. The dosage is based on your medical condition, body size, and response to treatment.

A healthcare professional should watch you for at least 1 hour after your infusion is finished to make sure you do not have an infusion reaction. (See Warning section). If you experience a severe infusion reaction, your infusion will be stopped and your doctor may decide to stop further treatments.
