Warnings
WARNING: LEFT VENTRICULAR DYSFUNCTION and EMBRYO-FETAL TOXICITY Left Ventricular Dysfunction: PERJETA can cause subclinical and clinical cardiac failure manifesting as decreased LVEF and CHF. Evaluate cardiac function prior to and during treatment. Discontinue PERJETA treatment for a confirmed clinically significant decrease in left ventricular function [see Dosage and Administration (2.3) , Warnings and Precautions (5.1) and Adverse Reactions (6.1) ]. 5 WARNINGS AND PRECAUTIONS Infusion-Related Reactions: PERJETA can cause serious infusion reactions, including fatal events: Monitor for signs and symptoms. If a significant infusion-associated reaction occurs, slow or interrupt the infusion and administer appropriate medical therapies. ( 5.3 ) Hypersensitivity Reactions/Anaphylaxis: PERJETA can cause hypersensitivity reactions, including anaphylaxis: Monitor for signs and symptoms, including angioedema. If a severe hypersensitivity reaction/anaphylaxis occurs, discontinue the infusion immediately and administer appropriate medical therapies. ( 5.4 ) 5.1 Left Ventricular Dysfunction PERJETA can cause left ventricular dysfunction, including symptomatic heart failure. 4 CONTRAINDICATIONS PERJETA is contraindicated in patients with known hypersensitivity to pertuzumab or to any of its excipients [see Warnings and Precautions (5.4)]. PERJETA is contraindicated in patients with known hypersensitivity to pertuzumab or to any of its excipients. ( 4 )
