Cetuximab
About Cetuximab
Cetuximab is a targeted prescription medicine used to treat advanced colorectal cancer and head and neck cancer. Eligibility criteria differ depending on the cancer type: before starting treatment for bowel cancer, your doctor will perform a RAS gene mutation test to confirm suitability, whereas for head and neck cancer, tumour EGFR protein expression or specific clinical staging is assessed. It is designed to slow or stop the growth of cancer cells by targeting specific proteins on their surface.
This medicine is given as an injection directly into a vein, typically once a week or every two weeks, depending on your treatment plan. To get the best results, it is important to keep all your scheduled appointments and maintain a balanced diet while drinking plenty of fluids. Protecting your skin from the sun is also highly recommended during your treatment.
While taking Cetuximab, you may experience common side effects like an acne-like rash, dry skin, or tiredness. However, if you experience serious side effects such as breathing difficulties, sudden chest pain, or a severe skin reaction, you must consult your doctor immediately.
Talk to your doctor before starting this medicine if you have a history of lung disease, heart rhythm issues, or abnormal salt levels in your blood. You must not receive this medicine if you have had a severe allergic reaction to Cetuximab, or if you have a RAS-mutant colorectal cancer, as the medicine is ineffective for this specific tumor type.
It is important to tell your healthcare provider about other treatments you are receiving, as combining this medicine with radiation can increase skin sensitivity, and you should avoid alcohol if it interacts with your overall treatment plan. Pregnant or breastfeeding individuals should not use this medicine, and elderly patients should consult their doctor for personalised monitoring.
Uses of Cetuximab
Medicinal Benefits
Cetuximab provides targeted treatment to help slow the growth of certain cancers and improve treatment outcomes. The key benefits of Cetuximab are as follows:
- Targeted tumour control: By directly blocking growth signals in cancer cells, Cetuximab helps limit tumour growth, which can reduce cancer-related pain and physical discomfort.
- Enhanced treatment success: When used with radiation or other chemotherapy, this medicine helps make those treatments more effective, leading to better control of the disease.
- Preservation of healthy tissue: Because it targets specific cancer cell proteins, it behaves differently from standard chemotherapy, aiming to spare more of your healthy cells.
Directions for Use
- Follow your doctor’s instructions on the dosage and timing of this medication to ensure safety.
- Cetuximab will be given in a hospital setting under the supervision of a physician trained and experienced in administering cancer chemotherapeutic drugs.
- Do not self-administer.

Habit Forming
Diet & Lifestyle Advise
- Protect your skin from the sun: This medicine makes your skin highly sensitive to ultraviolet (UV) light. Wear protective clothing, wide-brimmed hats, and apply broad-spectrum sunscreen (SPF 30 or higher) daily, even on cloudy days.
- Moisturise gently and follow preventive skin care: Use thick, alcohol-free moisturisers and mild, fragrance-free soaps. Avoid harsh over-the-counter acne products. Your oncology team may also prescribe preventive treatments from the start of therapy to reduce rash severity. These may include certain prescription oral antibiotics (such as doxycycline) or mild steroid creams (topical corticosteroids).
- Stay hydrated and monitor minerals: Drink plenty of water throughout the day. Because this medicine can cause low blood magnesium levels (hypomagnesaemia), your doctor will check your electrolyte levels before each infusion and periodically after treatment ends. If your levels drop below healthy clinical thresholds, oral supplements or intravenous (IV, given through a drip) magnesium replacement will be administered.
- Practice gentle nail care: Keep your fingernails and toenails clean and trimmed straight across to prevent painful nail bed infections. Wear protective gloves when washing dishes or doing yard work.
Special Advise
Do not skip any scheduled doctor or lab appointments.

Disease/Condition Glossary
Cancer: Cancer is a genetic change in which the body's cells divide uncontrollably and spread into surrounding tissues. There are two types of cancer: benign (localized) and metastatic (spread to the whole body). Types of cancer include blood, lung, breast, etc. Cancer growth can be prevented by chemotherapy, radiation, and stem cell therapy.
Metastatic cancer: Metastasis occurs when cancer cells move from the colon to other organs. This is also known as stage IV colon cancer or advanced colon cancer.
Head and Neck Cancer: Cancers of the larynx, throat, lips, mouth, nose, and salivary glands are among the head and neck cancers. Human papillomavirus (HPV) infection, excessive alcohol consumption, and tobacco use all raise the risk of head and neck cancer.

Yes, Cetuximab is a chemotherapy drug, but it is specifically classified as a monoclonal antibody. It works by targeting and blocking the epidermal growth factor receptor (EGFR) on cancer cells, which helps slow or stop tumour growth. It is used primarily for the treatment of certain types of cancers, such as colorectal cancer and head and neck cancers.
Cetuximab is a monoclonal antibody used to treat cancer. It is neither a cytotoxic agent nor a vesicant, but it acts as a radio sensitizer by enhancing the effects of radiation therapy on cancer cells.
Cetuximab is administered through intravenous infusion by the doctor or nurse. The infusion is typically given over a period of time, with the rate depending on the patient's tolerance and the treatment plan. Do not self-administer.
Yes, Cetuximab may cause hair loss as a common side effect. If you experience this symptom, manage stress, use gentle hair care practices, and eat nutritious food. However, if hair loss persists consult the doctor for further guidance.
Cetuximab may cause a rash as a side effect because it targets and blocks the epidermal growth factor receptor (EGFR), which plays a key role in skin cell growth and repair. Inhibiting EGFR can lead to skin inflammation and reactions, resulting in the rash. However, consult the doctor if this symptom persists or worsens.
The duration of a rash depends on its cause. Some rashes may last for only a few days, while others can persist for weeks or even months. If the rash persists or worsens, consult the doctor for proper diagnosis and treatment.
The side effects of Cetuximab include headache, inflammation of the lining of the intestine, mouth, and nose, nose bleeding, tiredness, irritation and redness of the eye, diarrhoea, feeling sick, vomiting, loss of appetite, and weight loss.
