IMPORTANT SAFETY INFORMATION
BOXED WARNING: SERIOUS CARDIOPULMONARY REACTIONS
Serious cardiopulmonary reactions, including fatalities, have occurred uncommonly during or following perflutren-containing microsphere administration. Most serious reactions occur within 30 minutes of administration.
Assess all patients for the presence of any condition that precludes DEFINITY® administration.
Always have resuscitation equipment and trained personnel readily available.
CONTRAINDICATIONS:
Contraindicated in patients with known or suspected hypersensitivity to perflutren lipid microsphere or its components, such as polyethylene glycol (PEG).
WARNINGS AND PRECAUTIONS:
Serious Cardiopulmonary Reactions have occurred during or following administration. The risk for these reactions may be increased among patients with unstable cardiopulmonary conditions (acute myocardial infarction, acute coronary artery syndromes, worsening or unstable congestive heart failure, or serious ventricular arrhythmias).
Serious Hypersensitivity Reactions have been observed during or shortly following administration including anaphylaxis, with manifestations that may include death. DEFINITY contains PEG and may increase risk of serious reactions including death in patients with prior hypersensitivity reaction(s) to PEG. Clinically assess patients for prior hypersensitivity reactions to products containing PEG. Monitor all patients for hypersensitivity reactions.
Systemic Embolization may occur in patients with a cardiac shunt. Assess patients with shunts for embolic phenomena following administration. DEFINITY is only for intravenous administration and must not be administered by intra-arterial injection.
There is a risk of Ventricular Arrhythmia Related to High Mechanical Index. Additionally, end-systolic triggering with high mechanical indices has been reported to cause ventricular arrhythmias. The maximum recommended mechanical index for use with DEFINITY is 0.8 in adult patients and 0.3 in pediatric patients.
Acute Pain Episodes in Patients with Sickle Cell Disease (SCD) shortly following administration have been reported. Discontinue DEFINITY in SCD patients experiencing new or worsening pain.
ADVERSE REACTIONS:
The most common adverse reactions (≥0.5%) are headache, back/renal pain, flushing, nausea, chest pain, injection site reactions, and dizziness.
You are encouraged to report negative side effects of prescription drugs to the FDA. Visit MedWatch or call 1-800-FDA-1088.
Please see the accompanying full Prescribing Information and important safety information, including BOXED WARNING for serious cardiopulmonary reactions.
