Warnings & Precautions

Here are the key warnings and precautions for using Vivitra 150 mg (trastuzumab):

1. Cardiotoxicity (Heart Damage)

• Risk of heart failure, especially with prior anthracycline use (like doxorubicin). Monitor left ventricular ejection fraction (LVEF) before and during treatment. Do not use in patients with significant heart dysfunction unless benefits outweigh risks.

2. Infusion-Related Reactions

• May cause fever, chills, nausea, hypotension, bronchospasm, or anaphylaxis. Usually occurs during the first infusion—monitor closely and premedicate if needed.
