Rare deaths due to heart problems (cardiopulmonary arrest) or sudden death have occurred in people with head and neck cancer treated with cetuximab. Before starting treatment with this medication, tell your doctor if you have a history of heart disease (such as heart failure, irregular heartbeat, previous heart attack). Get medical help right away if you develop chest/jaw/left arm pain, shortness of breath, or unusual sweating. Your doctor will order certain blood tests (including magnesium, calcium, and potassium) during and after your treatment to monitor and help decrease your risk for heart problems.

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 works by slowing or stopping the growth of cancer cells. It binds to a certain protein (epidermal growth factor receptor-EGFR) in some tumors. Cetuximab is a man-made protein (monoclonal antibody).

How to use Erbitux Vial

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.

Side Effects

See also Warning section.

Nausea, vomiting, constipation, diarrhea, headache, stomachache, backache, fever/chills, trouble sleeping, weight loss, fatigue, drowsiness, eye redness/itching, nail changes, dry skin, and mouth/throat sores may occur. Nausea and vomiting can be quite severe. In some cases, drug therapy may be necessary to prevent or relieve nausea and vomiting. Not eating before your treatment may help relieve vomiting. Changes in diet such as eating several small meals or limiting activity may help lessen some of these effects. If any of these effects last or get worse, tell your doctor or pharmacist promptly.

People using this medication may have serious side effects. However, you have been prescribed this drug because your doctor has judged that the benefit to you is greater than the risk of side effects. Careful monitoring by your doctor may decrease your risk.

An acne-like rash may occur. Depending on how severe this rash is, your doctor may delay your cetuximab treatment, lower your dose, treat the rash with antibiotics, or stop treatment with cetuximab to decrease this potentially serious side effect.

Tell your doctor right away if you have any serious side effects, including: confusion, depression, swelling of hands/feet/lower legs, dehydration, signs of serious infection (such as sore throat that doesn't go away, high fever, chills), signs of kidney problems (such as change in the amount of urine), decreased vision, severe dizziness, fast/slow/irregular heartbeat, severe muscle spasms.

Rarely, very serious lung problems may occur. Get medical help right away if you develop: trouble breathing, chest pain.

A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
