Totect

Generic name: Dexrazoxane
Drug class: Miscellaneous uncategorized agents

Usage of Totect

Totect is used to protect the heart and other tissues from harmful side effects caused by certain cancer medications.

Totect is used in men or women to treat a condition called extravasation (es-TRA-va-ZAY-shun). Extravasation happens when an injected medicine escapes from the blood vessels and circulates into tissues in the body. Serious tissue damage can occur when extravasation happens during injection of certain cancer medications.

Totect is also used to help prevent chemotherapy-related heart problems in women who are receiving doxorubicin for metastatic breast cancer. This medicine is given only after you have received enough doxorubicin infusions to amount to a certain total dose.
