Warnings
WARNING: EMBRYO-FETAL TOXICITY ERIVEDGE can cause embryo-fetal death or severe birth defects when administered to a pregnant woman. ERIVEDGE is embryotoxic, fetotoxic, and teratogenic in animals. Teratogenic effects included severe midline defects, missing digits, and other irreversible malformations [see Warnings and Precautions (5.1) , Use in Specific Populations (8.1) ] . Verify the pregnancy status of females of reproductive potential within 7 days prior to initiating ERIVEDGE. 5 WARNINGS AND PRECAUTIONS Embryo-Fetal Toxicity: Advise patients not to donate blood or blood products while receiving ERIVEDGE and for 24 months after the final dose of ERIVEDGE ( 5.1 ) Advise males not to donate semen during and for 3 months after therapy ( 5.1 , 8.3 ) Severe Cutaneous Adverse Reactions: Permanently discontinue ERIVEDGE in patients with these reactions ( 5.2 ) Musculoskeletal Adverse Reactions: Temporary dose interruption or discontinuation may be required for these reactions ( 5.3 ) Premature fusion of the epiphyses ( 5.4 , 8.4 ) 5.1 Embryo-Fetal Toxicity Based on its mechanism of action, ERIVEDGE can cause embryo-fetal death or severe birth defects when administered to a pregnant woman. 4 CONTRAINDICATIONS None. None.
