WARNING: Use of trastuzumab may lead to serious heart problems, including heart failure. Your doctor may need to stop this medication if these problems occur. Patients who also use anthracyclines (e.g., doxorubicin) and cyclophosphamide are more likely to develop heart problems. Trastuzumab use may also result in several other severe, rarely fatal, problems. Specifically, these are allergic reactions, IV dosing (infusion reaction), and lung disease (acute respiratory distress syndrome-ARDS). These problems, if they occur, usually happen while the drug is being given, or within 24 hours of the dose. The IV dose should be interrupted if you experience trouble breathing, or severe dizziness/very low blood pressure; consult your doctor or pharmacist immediately. Trastuzumab treatment may need to be stopped if severe allergic or lung problems occur; seek immediate medical attention. Read the Side Effects Section carefully. It includes symptoms and advice regarding the medical problems noted in this section.
