IMPORTANT SAFETY INFORMATION
WARNINGS AND PRECAUTIONS
Myelosuppression: TOTECT is associated with leukopenia, neutropenia, and thrombocytopenia. Perform hematological monitoring during treatment with TOTECT and cytotoxic chemotherapy as the myelosuppression and cytotoxic potential may be additive to that of chemotherapy alone.
Anaphylactic/Hypersensitivity Reactions: Hypersensitivity reactions including anaphylactic reaction, angioedema, skin reactions, bronchospasm, respiratory distress, hypotension and loss of consciousness have occurred in patients treated with dexrazoxane products and anthracyclines. Previous history of allergy to dexrazoxane products should be carefully considered prior to administration. Consider permanent discontinuation in patients with severe hypersensitivity reactions.
Embryo-Fetal Toxicity: TOTECT can cause fetal harm when administered to a pregnant woman. Advise patients of potential risk and to use effective contraception during treatment and 6 months following the last dose of TOTECT. Use in patients with hepatic impairment is not recommended.
TOTECT is not recommended for use with dimethyl sulfoxide (DMSO).
In the clinical studies, TOTECT was administered to patients also receiving chemotherapeutic agents for cancer, and the adverse reaction profile reflects the combination of TOTECT, underlying disease, and already administered chemotherapy. The most common adverse reactions (≥15%) are nausea, fever, injection site pain, vomiting, and postoperative infection.
