Erbitux intravenous

GENERIC NAME(S): CETUXIMAB

WARNINGS:

Severe (sometimes fatal) reactions have occurred in people while receiving cetuximab. Your risk may be higher if you have a history of tick bites or have a severe allergic reaction to meat (such as beef, pork). Before receiving cetuximab, tell your doctor if you have either of these conditions. Your doctor will carefully monitor you during and for at least one hour after your infusion. Tell your doctor right away if you have shortness of breath, hoarseness, itching, or dizziness. Your doctor may stop treatment with this medication if you have a severe reaction.

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 that has spread to other parts of the body. 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).

OTHER USES: This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional. Use this drug for a condition that is listed in this section only if it has been so prescribed by your health care professional.

Cetuximab may also be used for kidney cancer.

How to use Erbitux intravenous

Cetuximab is given by injection into a vein usually once a week by a healthcare professional. Another drug (e.g., diphenhydramine) may be given before you receive cetuximab to lessen the chance of certain side effects. The first dose (loading dose) is larger and is given over 2 hours. All other doses (maintenance doses) are smaller and are given over 1 hour if tolerated. 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 these effects persist or worsen, notify your doctor or pharmacist promptly.

Many people using this medication have serious side effects. However, your doctor has prescribed this drug because he or she 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 immediately if any of these unlikely but serious side effects occur: confusion, depression, swelling of hands/feet/lower legs, dehydration, serious infection (e.g., high fever, chills, persistent sore throat), change in amount of urine, decreased vision, severe dizziness, fast/slow/irregular heartbeat, severe muscle spasms.

Rarely, very serious lung problems may occur. Seek immediate medical attention if you develop: trouble breathing.

A very serious allergic reaction to this drug is unlikely, but seek immediate medical attention if it occurs. Symptoms of a serious allergic reaction may include: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.

This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.
