Dose calculations are directed toward achieving an FVIII activity level of 30-40% for most mild hemorrhages, of at least 50% for severe bleeds (eg, from trauma) or prophylaxis of major dental surgery or major surgery, and 80-100% in life-threatening hemorrhage. Hospitalization is reserved for severe or life-threatening bleeds, such as large-soft tissue bleeds; retroperitoneal hemorrhage or other internal bleeding; and hemorrhage related to head injury, surgery, or dental work.
