Typical dosage for Busulfan
This medication is an injection into a vein (intravenous, IV) that’s given by a healthcare provider. Your provider will calculate your dose of busulfan (Busulfex) based on your body weight.
One possible dosing regimen is 0.8 mg/kg given every 6 hours for 4 consecutive days before a stem cell transplant. This is a total of 16 doses. Your course of busulfan (Busulfex) will begin 7 days before your transplant (on days -7, -6, -5, and -4, with day 0 as the day you’ll receive a transplant). With this conditioning regimen, busulfan (Busulfex) is given along with another anticancer medication called cyclophosphamide.
