Cetuxa 100mg 20ml Injection

Cetuxa 100mg 20ml Injection contains Cetuximab 100mg, a monoclonal antibody used to treat certain metastatic cancers, including colorectal cancer and head and neck cancer.

Benefits

Cetuximab works by specifically targeting the epidermal growth factor receptor (EGFR) on cancer cells, which helps to slow or stop tumor growth and spread. This targeted action can lead to reduced cell proliferation and may induce programmed cell death in cancer cells. It can also enhance the therapeutic impact when used in combination with chemotherapy or radiation therapy for specific cancer types.

Uses and Indications

• Metastatic colorectal cancer, particularly in patients with specific genetic profiles (such as KRAS wild-type tumors).
• Head and neck squamous cell carcinoma, including locally advanced, recurrent, or metastatic disease.

The Cetuxa 100mg 20ml Injection contains:

• Cetuximab 100mg (active ingredient).
• Excipients: Sodium chloride, glycine, polysorbate 80, citric acid monohydrate, sodium hydroxide, and water for injections.

Dosage and Administration

1. Cetuxa 100mg 20ml Injection is administered as an intravenous (IV) infusion by a qualified healthcare professional in a clinic or hospital setting.
2. The exact dosage, schedule, and duration of treatment are determined by your oncologist based on your body weight, cancer type, and overall treatment plan.
3. Premedication with an antihistamine and a corticosteroid is typically recommended at least one hour prior to the first infusion and subsequent infusions to reduce the risk of infusion-related reactions.
4. The initial dose is usually administered over approximately 120 minutes, with subsequent weekly doses given over 60 minutes, or biweekly doses over 120 minutes, depending on the regimen.

Storage and Disposal

• Store Cetuxa 100mg 20ml Injection in a refrigerator between 2°C to 8°C.
• Do not freeze the medicine and protect it from light.
• Keep this medicine out of the reach of children.
• Any unused portion of the vial should be discarded.

Precautions and Safety

• Severe infusion reactions can occur, especially with the first dose. Your doctor will monitor you closely during and after the infusion. Inform your doctor if you have a history of tick bites or red meat allergy, as this may increase the risk.
• This medicine is not recommended during pregnancy or breastfeeding due to potential risks to the developing infant. Discuss effective contraception methods with your doctor.
• Close monitoring of serum electrolytes, including magnesium, potassium, and calcium levels, is necessary during and after treatment.
• Patients with severe kidney or liver disease should use Cetuxa with caution.
• Genetic testing for RAS and BRAF V600E mutations may be required before initiating treatment for colorectal cancer, as the efficacy of cetuximab can be affected by these mutations.
• Avoid alcohol consumption during treatment.

Side Effects and Risks

• Common side effects include skin rash (acneiform dermatitis), itching, dry or red skin, fatigue, weakness, fever, chills, nausea, vomiting, diarrhea, headache, and low levels of magnesium or potassium in the blood.
• Serious side effects, though less common, can include severe infusion reactions (e.g., breathing difficulty, chest pain, low blood pressure), severe skin infections or peeling, lung problems, severe allergic reactions, heart rhythm disturbances, and cardiopulmonary arrest. Seek immediate medical attention if these occur.
