Hertraz 440mg Injection (Trastuzumab) – Treatment for HER2+ Breast & Stomach Cancer

Hertraz 440mg Injection is a targeted therapy used to treat HER2-positive breast cancer and stomach cancer. It works by blocking the HER2 protein, which promotes the growth of cancer cells. Administered intravenously by a healthcare professional, this monoclonal antibody helps destroy cancer cells and inhibits tumor progression. Treatment duration varies based on individual response, and regular monitoring (blood tests, heart/liver function) is essential. While side effects like nausea or fatigue may occur, Hertraz significantly improves survival rates in eligible patients. Strictly follow your oncologist’s dosage instructions and avoid self-administration.

Uses of Hertraz Injection:

• HER2-positive breast cancer
• HER2-positive metastatic stomach (gastric) cancer

Benefits of Hertraz Injection:

Hertraz specifically targets HER2 receptors, slowing or stopping cancer cell growth. It is often combined with chemotherapy for better outcomes. Clinical studies show improved survival rates in HER2-positive patients when used as prescribed.

Side Effects of Hertraz Injection:

Common side effects (usually manageable):

• Fever, chills, fatigue
• Nausea, diarrhea, taste changes
• Headache, insomnia, rash
• Mouth inflammation (stomatitis)
• Low blood cell counts (increased infection risk)

Serious side effects (require immediate medical attention):

• Heart problems (shortness of breath, swelling in limbs)
• Severe allergic reactions
• Lung complications (cough, breathing difficulty)

How to Use Hertraz Injection?

• Administered ONLY by a healthcare provider via IV infusion or subcutaneous injection.
• Dosage depends on body weight and cancer type.
• Pre-medication may be given to reduce infusion reactions.

How Hertraz Injection Works?

It is a recombinant IgG1 monoclonal antibody that binds to HER2 receptors on cancer cells. This action:
1. Blocks signals that promote cancer growth.
2. Triggers the immune system to attack cancer cells.
3. Enhances the effectiveness of chemotherapy.

Safety Advice

• Alcohol: Unsafe—may worsen drowsiness.
• Pregnancy: Strictly avoided (risk of fetal harm).
• Breastfeeding: Not recommended (potential baby harm).
• Driving: Caution advised (may cause dizziness).

FAQs:

Q1. What are the serious side effects of Hertraz 440mg Injection?

Watch for heart problems (rapid heartbeat, swelling), severe infections (fever, chills), lung issues (cough, breathlessness), or allergic reactions (rash, face swelling). Seek emergency care if these occur.

Q2. How long after treatment can I plan pregnancy?

Use effective contraception during therapy and for 7 months after the last dose. Consult your doctor before planning pregnancy.

Q3. How long is the treatment duration?

For early breast cancer: Typically 1 year. For advanced cancer: Until disease progression or unacceptable toxicity occurs.

Q4. Is fasting required before administration?

No. It is given by IV infusion or subcutaneous injection without fasting requirements.

Q5. Can it be used for HER2-negative cancer?

No. It only works for HER2-positive cancers confirmed by diagnostic tests.

Q6. Why does my doctor check my heart before treatment?

It may cause heart damage (especially with anthracycline chemotherapy). Regular cardiac monitoring (ECHO, ECG) is essential.
