Preparation of Totect®
Step 1. Each vial of Totect® (dexrazoxane for injection) (500 mg) must first be mixed with 50 mL of the enclosed diluent. The resultant solution contains 10 mg/mL. This resultant solution should be used immediately (within 2 hours) after preparation. It contains no antibacterial preservative.
Step 2. Withdraw the recommended dose from the solution containing 10 mg/mL as prepared in Step 1 and further dilute into an infusion bag containing 1000 mL 0.9% Sodium Chloride. In order to obtain the required dose more than one vial may be needed. Totect® must not be mixed with any other drugs.
The infusion bag should be used immediately after preparation. The product is stable for 4 hours from the time of preparation when stored below 25ºC (77ºF).
The solution of Totect® is slightly yellow.
Parenteral drug products should be inspected visually for particulate matter prior to administration, whenever solution and container permit. Solutions containing a precipitate should be discarded. Vials are for single use only. Unused solution should be discarded.
Totect® should not be mixed or administered with any other drug during the infusion. Administer as an intravenous infusion over 1 to 2 hours at room temperature and normal light conditions in a large caliber vein in an extremity/area other than the one affected by the extravasation. Cooling procedures such as ice packs, if used, should be removed from the extravasation area at least 15 minutes before Totect® administration in order to allow sufficient blood flow to the area of extravasation. Treatment on Day 2 and Day 3 should start at the same hour (+/- 3 hours) as on the first day.
