IV: (Adults and Children) General dosing– Dose required (IU) = body weight (kg) x Desired Factor VIII increase (IU/dL or % normal) x 0.5 (IU/kg per IU/dL).
Control/prevention of bleeding episodes
IV: (Adults and Children) Minor bleeding (early hemarthrosis, minor muscle or oral bleeding)– 20–40% of normal Factor VIII level required every 12–24 hr for at least one day until resolution of bleeding, Moderate bleeding (muscle bleeding, bleeding into the oral cavity, mild head trauma)– 30–60% of normal Factor VIII level required every 12–24 hr until pain/disability resolves (3–4 days), Major bleeding (life/limb–threatening hemorrhage, GI bleeding, intracranial/intra-abdominal/intrathoracic bleeding, fractures)– 60–100% of normal Factor VIII level required every 8–24 hr until resolution of bleeding (7–10 days).
IV: (Adults and Children) Minor procedures (including tooth extraction)– 30–60 % of normal Factor VIII level required every 24 hr for one day until healing achieved; Major procedures– 80–100 % of normal Factor VIII level required every 8–24 hr pre- and post-operative until adequate wound healing achieved then continue for 7–10 days maintaining 30–60% of normal activity.
IV: (Adults and Children ≥12 yr): 20–50 IU/kg three times weekly or 20–40 IU/kg every other day.
IV: (Children <12 yr): 25–60 IU/kg three times weekly or 25–50 IU/kg every other day.
Lyophilized powder for injection(requires reconstitution): 250 IU single use vial, 500 IU single use vial, 1000 IU single use vial, 1500 IU single use vial, 2000 IU single use vial, 3000 IU single use vial
Monitor for signs and symptoms of hypersensitivity reactions or anaphylaxis (angioedema, chest tightness, dyspnea, wheezing, urticaria, pruritus). Discontinue Immediately and symptomatic treatment.
Lab Test Considerations: Monitor plasma factor VIII activity levels by one-stage clotting assay or chromogenic substrate assay to confirm adequate factor VIII levels have been achieved and maintained, when clinically indicated.
Monitor patients for development of inhibitors. If expected plasma levels of factor VIII activity are not attained, or if bleeding is not controlled with appropriate dose, test for factor VIII inhibitors. Determine inhibitor levels in Bethesda Units.
Accidental needle stick with a needle contaminated with blood can transmit infectious viruses including HIV (AIDS) and hepatitis. Obtain immediate medical attention if injury occurs.
Turcoctocog alfa can be infused at a hemophilia treatment center, at a health care professional's office or in the patient's home, with training.
IV Push: Bring vial and pre-filled syringe to room temperature. Do not remove the vial adapter from the protective cap. Reconstitute each vial witn 4 mL 0.9% NaCl. Follow manufacturer's instructions to prepare and reconstitute. Solution is clear to slightly unclear, without particles; do not administer solutions that are discolored or contain particulate matter. Invert turoctocog alfa vial and slowly draw solution into syringe. Stable at room temperature for 4 hr after reconstitution.
Rate: Inject slowly over 2 to 5 minutes.
Instruct patient in correct method for self-administration and care of equipment. If a dose is missed, omit and administer next dose as scheduled. Do not stop using without consulting health care professional. Advise patient to read Patient Product Information before using and with each refill; new information may be available.
Caution patient to notify health care professional immediately if signs and symptoms of hypersensitivity reactions or anaphylaxis (rashes, hives, difficulty breathing, shortness of breath, wheezing, chest or throat tightness, difficulty swallowing, swelling of lips and tongue, light-headedness, dizziness, loss of consciousness, pale and cold skin, fast heart beat, low BP, red or swollen face or hands) occur.
Advise patient to notify health care professional if lack of response occurs.
Instruct patient to notify health care professional of all Rx or OTC medications, vitamins, or herbal products being taken and to consult with health care professional before taking other medications.
Advise patient to notify health care professional of treatment regimen prior to medical treatment or surgery.
Instruct patient to consult with health care professional prior to traveling. While traveling, patients should be advised to bring an adequate supply of turoctocog alfa based on their current treatment regimen.
Advise female patient to notify health care professional if pregnancy is planned or suspected or if breastfeeding.
