Dosage/Direction for Use
Erbitux must be administered under the supervision of a physician experienced in the use of antineoplastic medicinal products. Close monitoring is required during the infusion and for at least 1 hr after the end of the infusion. Availability of resuscitation equipment must be ensured.
Prior to the 1st infusion, patients must receive premedication with an antihistamine and a corticosteroid. This premedication is recommended prior to all subsequent infusions.
In all indications, Erbitux is administered once a week. The very 1st dose is cetuximab 400 mg/m2 body surface area. All subsequent weekly doses are 250 mg/m2 each.
Colorectal Cancer: In patients with metastatic colorectal cancer, cetuximab is used in combination with chemotherapy or as a single agent (see Pharmacology under Actions). Detection of KRAS mutational status must be performed prior to the 1st cetuximab infusion. It is important that a validated test method is used by an experienced laboratory (see Pharmacology under Actions and Precautions).
For the dosage or recommended dose modifications of concomitantly used chemotherapeutic agents, refer to the product information for these medicinal products. They must not be administered earlier than 1 hr after the end of the cetuximab infusion.
It is recommended that cetuximab treatment be continued until progression of the underlying disease.

It is recommended to start cetuximab therapy 1 week before radiation therapy and to continue cetuximab therapy until the end of the radiation therapy period.
In patients with recurrent and/or metastatic squamous cell cancer of the head and neck, cetuximab is used in combination with platinum-based chemotherapy followed by cetuximab as maintenance therapy until disease progression (see Pharmacology under Actions). Chemotherapy must not be administered earlier than 1 hr after the end of the cetuximab infusion.
