To date, over 1.5 million doses of rFVIIa have been given to inhibitor patients, with an excellent efficacy and safety record.Because of its short half-life, alternative means of dosing and infusing rFVIIa have been explored and are reviewed here.Keywords: hemophilia, inhibitor, recombinant, factor VIIa, inhibitors.
