IMPORTANT SAFETY INFORMATION

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 [see Contraindications (4)].
Always have resuscitation equipment and trained personnel readily available [see Warnings and Precautions (5.1)].

DEFINITY® Vial for (Perflutren Lipid Microsphere) Injectable Suspension

INDICATIONS

CONTRAINDICATIONS

DEFINITY® is contraindicated in patients with known or suspected hypersensitivity to perflutren lipid microsphere or its components, such as polyethylene glycol (PEG) [see Warnings and Precautions (5.2) and Description (11)].

IMPORTANT SAFETY INFORMATION

WARNING: SERIOUS CARDIOPULMONARY REACTIONS

Assess all patients for the presence of any condition that precludes DEFINITY® administration [see Contraindications (4)].
Always have resuscitation equipment and trained personnel readily available [see Warnings and Precautions (5.1)].

In postmarketing use, rare but serious cardiopulmonary or hypersensitivity reactions have been reported during or shortly following perflutren and PEG-containing microsphere administration [see Adverse Reactions (6)]. The risk for these reactions may be increased among patients with unstable cardiopulmonary conditions and/or with pre-existing PEG hypersensitivity [see Adverse Reactions (6.2)]. It is not always possible to reliably establish a causal relationship to drug exposure due to the presence of underlying conditions.

Patients with sickle cell disease may be at higher risk of painful crisis and DEFINITY® should be administered with caution.

Please see accompanying full Prescribing Information, including boxed WARNING regarding serious cardiopulmonary reactions.
