Seek Immediate Medical Attention If You Experience:
- Signs of an allergic reaction: hives, rash, itching, swelling of the face/lips/tongue/throat, difficulty breathing, chest tightness, dizziness, feeling faint.
- Signs of bleeding: unusual bruising, prolonged bleeding from cuts, nosebleeds, blood in urine or stools, severe joint pain or swelling, headache with stiff neck or vision changes.
- Signs that the medication is not working (possible inhibitor development): increased frequency or severity of bleeding episodes, or bleeding that doesn't stop with your usual dose.
Before Using This Medicine
It is essential to inform your doctor about the following:
Any allergies you have, including allergies to this medication, its components, or other substances, such as foods or drugs. Be sure to describe the symptoms you experienced.
All medications you are currently taking, including prescription and over-the-counter (OTC) drugs, natural products, and vitamins. This is crucial to avoid potential interactions.
* Any existing health problems, as this medication may affect your condition or interact with other health issues.
To ensure your safety, it is vital to verify that this medication is compatible with all your medications and health conditions. Never start, stop, or adjust the dosage of any medication without first consulting your doctor.
Precautions & Cautions
Regular blood tests and other laboratory assessments should be conducted as directed by your doctor to monitor your condition.
If you experience unexplained bruising, bleeding, or if bleeding does not stop after taking this medication, contact your doctor immediately. These symptoms may indicate that your current dose is not effective.
Before traveling, consult with your doctor to ensure you have an adequate supply of this medication for the duration of your trip.
If you are pregnant, planning to become pregnant, or are breastfeeding, notify your doctor. You and your doctor will need to discuss the potential benefits and risks of this medication to both you and your baby.
Overdose Information
Overdose Symptoms:
- While an overdose is unlikely to cause severe adverse effects, very high Factor VIII levels could theoretically increase the risk of thrombotic events (blood clots).
What to Do:
In case of suspected overdose, contact your healthcare provider or emergency services immediately. Call 911 or the Poison Control Center at 1-800-222-1222.
Drug Interactions
Monitoring
Baseline Monitoring
Rationale: To determine baseline FVIII levels and guide initial dosing.
Timing: Prior to initiation of therapy.
Rationale: To detect pre-existing inhibitors to FVIII, which can render treatment ineffective.
Timing: Prior to initiation of therapy, especially in previously untreated patients (PUPs).
Routine Monitoring
Frequency: Periodically, especially during treatment of bleeding episodes or surgical procedures, and to guide prophylactic dosing.
Target: Dependent on clinical situation (e.g., >30% for minor bleeds, >80-100% for major surgery).
Action Threshold: Adjust dose or frequency if levels are not within target range or if clinical response is inadequate.
Frequency: Regularly (e.g., every 3-6 months) in all patients, and particularly if expected clinical response is not achieved.
Target: Negative (less than 0.6 Bethesda Units/mL)
Action Threshold: If inhibitors are detected, treatment strategy may need to be altered (e.g., higher doses, bypassing agents).
Frequency: Continuously during bleeding episodes or prophylaxis.
Target: Cessation of bleeding, prevention of bleeding episodes.
Action Threshold: If bleeding persists or prophylaxis fails, re-evaluate dose, frequency, or consider inhibitor development.
Symptom Monitoring
- Signs of bleeding (e.g., joint pain/swelling, bruising, prolonged bleeding from minor cuts, blood in urine/stools)
- Signs of allergic or hypersensitivity reactions (e.g., rash, hives, itching, facial swelling, shortness of breath, chest tightness, dizziness, faintness)
- Signs of inhibitor development (e.g., increased frequency or severity of bleeding, lack of response to usual doses of Factor VIII)
Special Patient Groups
Pregnancy
Use only if clearly needed. Animal reproduction studies have not been conducted with Nuwiq. It is not known whether Nuwiq can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Factor VIII is a natural component of human plasma, and its replacement is essential for hemostasis in hemophilia A.
Trimester-Specific Risks:
Lactation
It is not known whether Nuwiq is excreted in human milk. However, human Factor VIII is a normal component of human plasma. Consider the developmental and health benefits of breastfeeding along with the motherβs clinical need for Nuwiq and any potential adverse effects on the breastfed infant from Nuwiq or from the underlying maternal condition.
Pediatric Use
Nuwiq is approved for use in pediatric patients, including neonates, infants, children, and adolescents. Dosing is weight-based and individualized, similar to adults. Pediatric patients, especially previously untreated patients (PUPs), may have a higher risk of inhibitor development.
Geriatric Use
Clinical studies of Nuwiq did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. However, no specific dose adjustments are typically required based on age alone for Factor VIII products.
Clinical Information
Clinical Pearls
- Nuwiq is a third-generation recombinant Factor VIII product, produced in a human cell line (HEK 293F) and free of animal- or human-derived additives in the cell culture, purification, and final formulation steps, which may be preferred by some patients.
- Individualize dosing based on the patient's Factor VIII levels, type and severity of bleeding, and clinical response.
- Regular monitoring for Factor VIII inhibitors is crucial, especially in previously untreated patients (PUPs) and young children, as inhibitor development is the most serious complication of Factor VIII replacement therapy.
- Patients should be educated on self-administration techniques, proper storage, and signs of allergic reactions or inhibitor development.
- Prophylaxis is the standard of care for severe hemophilia A to prevent bleeding episodes and joint damage.
Alternative Therapies
- Other recombinant Factor VIII products (e.g., Advate, Eloctate, Jivi, Kogenate, Novoeight, Recombinate, Xyntha)
- Plasma-derived Factor VIII products (e.g., Humate-P, Alphanate)
- Extended half-life Factor VIII products (e.g., Eloctate, Jivi, Adynovate, Hemlibra (emicizumab) - a bispecific antibody that mimics FVIIIa activity, not a FVIII replacement)
- Bypassing agents (for patients with inhibitors): Activated Prothrombin Complex Concentrate (aPCC, e.g., FEIBA), Recombinant Factor VIIa (rFVIIa, e.g., NovoSeven RT)
- Antifibrinolytic agents (e.g., tranexamic acid, aminocaproic acid) as adjunctive therapy for mild bleeding or prophylaxis during dental procedures.
