Fanhdi belongs to the group of medications known as antihemorrhagics: blood coagulation factors: factor von Willebrand and factor VIII of blood coagulation in combination.
This medication is used for:
Hemophilia A
Fanhdi is indicated for the treatment and prophylaxis (prevention) of bleeding in patients with hemophilia A (congenital deficiency of factor VIII). These patients do not have enough functional factor VIII. Fanhdi serves to increase the amount of factor VIII in the blood, thus allowing the blood to clot.
This product may be useful in the management of acquired factor VIII deficiency.
Von Willebrand disease
Fanhdi is indicated for the treatment of bleeding and surgical bleeding prophylaxis in patients with von Willebrand disease (VWD) when treatment with desmopressin (DDAVP) alone is not effective or contraindicated.
Patients may suffer from different types of VWD.All types of VWD are congenital diseases where bleeding can last longer than expected. This may be due to a lack of FVW in the blood or because FVW does not function as it should.
No use Fanhdi
If you are allergic to the human coagulation factor VIII complex and factor von Willebrand or any of the other components of this medication (listed in section 6).
If you have any doubts about the above, consult your doctor.
Warnings and precautions
Consult your doctor, pharmacist, or nurse before starting to use Fanhdi.
The formation of inhibitors (antibodies) is a known complication that may occur during treatment with all factor VIII composite medications. These inhibitors, especially in large quantities, prevent the treatment from working correctly, so you and your child will be closely monitored for the development of these inhibitors. If your bleeding or your child's bleeding is not being controlled with Fanhdi, consult your doctor immediately.
Despite these measures, when administering medications prepared from blood or human plasma, the possibility of transmission of infections cannot be completely ruled out. This also applies to unknown or emerging viruses and other types of infections.
The measures taken are considered effective for enveloped viruses such as human immunodeficiency virus (HIV), hepatitis B virus, and hepatitis C virus, and for non-enveloped viruses such as hepatitis A virus. The measures taken may have limited value for non-enveloped viruses such as parvovirus B19.
Parvovirus B19 infection can be severe for a pregnant woman (fetal infection) and for individuals with a weakened immune system or those with some type of anemia (e.g., with sickle cell anemia or hemolytic anemia).
Your doctor may recommend that you consider hepatitis A and B vaccination if you regularly/repeatedly receive human plasma-derived factor VIII concentrates.
Each time you are administered a dose of Fanhdi, it is recommended to record the name and batch number of the medication to maintain a record of the batches used.
See also section 4.
Children and adolescents
The warnings and precautions indicated apply to both adults and children.
Use of Fanhdi with other medications
Inform your doctor or pharmacist if you are taking, have taken recently, or may need to take any other medication.
No interactions have been observed between the human coagulation factor VIII complex and factor von Willebrand and other medications.
Pregnancy and breastfeeding
Consult your doctor or pharmacist before using any medication.
During pregnancy and breastfeeding, the FVIII/FVW complex may be used only if clearly indicated.
Driving and operating machinery
No indication exists that Fanhdi may affect the ability to drive vehicles or operate machinery.
Sodium content
The residual sodium content in Fanhdi, resulting from the manufacturing process, does not exceed 23 mg per vial in the 250, 500, and 1000 UI presentations, and 34.5 mg per vial in the 1500 UI presentation. This is equivalent to 1.15% and 1.72% respectively of the maximum daily sodium recommended for an adult. However, depending on the patient's weight and dosage, the patient may receive more than one vial.
The product must be administered intravenously. The administration rate must not exceed 10 ml/min.
Follow exactly the administration instructions indicated by your doctor or by the healthcare staff at the hemophilia center. If you have any doubts, consult your doctor or pharmacist.
The amount of Fanhdi you should use depends on many factors, such as your weight, your clinical condition, and the location and importance of the bleeding. Your doctor will calculate the dose of Fanhdi and how often and at what intervals it should be administered to achieve the necessary level of factor VIII or factor von Willebrand in your blood.
Your doctor will inform you of the duration of your treatment with Fanhdi.
Preparation of the solution:
Ensure that you work in the most suitable conditions at all stages of the process to avoid contamination of the product.
Administration
Prepare the patient's injection site, separate the syringe from the rest, and inject the product using the butterfly needle provided at a rate of 3ml/min intravenously. The administration rate must not exceed 10 ml/min to avoid vasomotor reactions.
It is recommended to use the injection equipment provided with the medication. In the event that medical perfusion equipment is used, check the compatibility of the system with the pre-loaded syringe. It may be necessary to use an adapter to ensure proper administration of the product.
The administration equipment must not be reused. In no case should the unused fraction be stored in the refrigerator.
If you use more Fanhdi than you should
No cases of overdose with human coagulation factor VIII and factor von Willebrand complex have been reported. However, if you have used Fanhdi more than you should, consult your doctor or pharmacist immediately.
In case of overdose or accidental administration, consult the Toxicological Information Service. Phone 91 562 04 20.
If you forgot to use Fanhdi
Like all medicines, this medicine can cause side effects, although not everyone will experience them.
In rare cases, you may notice some of these side effects after the administration of Fanhdi:
It is also impossible to completely rule out the possibility of anaphylactic shock. If you notice any of the following symptomsduring administration:
may be an early sign of hypersensitivity and anaphylactic reaction. If an allergic or anaphylactic reaction occurs, administration should be interrupted and your doctor should be consulted immediately.
Hemophilia A
In children who have not received prior treatment with factor VIII-containing medications, the production of inhibitor antibodies (see section 2) may occur very frequently (more than 1 in 10 patients); however, in patients who have received prior treatment with factor VIII (more than 150 days of treatment), the risk is infrequent (less than 1 in 100 patients). If this happens, the medications you or your child take may not work properly, and you or your child may experience persistent bleeding. In that case, contact your doctor immediately.
Von Willebrand disease
When using a FVW product containing FVIII to treat EVW, continued treatment may cause excessive increases in FVIII levels in the blood. This may increase the risk of altered blood flow (thrombosis).
If you are a patient with known clinical or laboratory risk factors, your doctor should monitor the first signs of thrombosis. Your doctor should establish a prevention (prophylaxis) of thrombotic episodes, in accordance with current recommendations.
Especially if you are a patient with type 3 von Willebrand disease, in very rare cases, you may develop neutralizing antibodies (inhibitors) to factor von Willebrand. If these inhibitors appear, the factor von Willebrand is less effective in controlling bleeding. In the case of continued bleeding, the presence of these inhibitors in your blood should be analyzed. These antibodies may appear associated with anaphylactic reactions. Therefore, in patients who experience anaphylactic reactions, the presence of inhibitors should be evaluated. In such cases, consult your doctor immediately.
For information on viral safety, see section 2.

This information is intended solely for healthcare professionals:
Dosage
Hemophilia A
The dosage and duration of treatment depend on the severity of the factor VIII deficiency, the location and severity of the hemorrhage, and the patient's clinical condition.
The number of factor VIII units administered is expressed in International Units (UI), in relation to the World Health Organization (WHO) standard for factor VIII concentrates. The plasma activity of factor VIII is expressed as a percentage (in relation to normal human plasma) or in International Units (in relation to an international standard for factor VIII in plasma).
One International Unit (UI) of factor VIII activity is equivalent to the amount of factor VIII in 1 ml of normal human plasma.
On-demand treatment
The calculation of the required dose of factor VIII is based on the empirical observation that 1 International Unit (UI) of factor VIII per kg of body weight increases the plasma activity of factor VIII by 2.1 ± 0.4% of normal activity. The required dose is determined using the following formula:
Required units = body weight (kg) x desired increase in factor VIII (%) (UI/dl) x 0.5
The dose and administration frequency must be calculated based on the patient's clinical response.
In the case of hemorrhagic episodes such as those listed below, the factor VIII activity should not be less than the established plasma activity level (in % of normal plasma or UI/dl) in the corresponding period. The following table can be used as a guide for dosing in hemorrhagic episodes and surgery:
Severity of hemorrhage/ Type of surgery | Required factor VIII level (%)(UI/dl) | Dosage frequency (hours)/ Duration of therapy (days) |
Hemorrhage | ||
Minor hemarthrosis and oral or muscular bleeding | 20 - 40 | Repeat every 12 - 24 hours. At least 1 day, until the hemorrhagic episode manifested by pain stops or until healing. |
Moderate hemarthrosis and muscular or hematoma bleeding | 30 - 60 | Repeat administration every 12 - 24 hours for 3 - 4 days or more until pain and acute disability disappear. |
Bleeding with life-threatening risk | 60 - 100 | Repeat administration every 8 - 24 hours until the risk disappears. |
Surgery | ||
Minor surgeryincluding dental extractions Major surgery | 30 - 60 80 - 100 (pre- and postoperative) | Every 24 hours, at least 1 day until healing. Repeat administration every 8 - 24 hours until adequate wound healing, and continue therapy for at least 7 days to maintain a factor VIII activity level of 30% to 60% (UI/dl). |
Prophylaxis
In long-term prophylaxis to prevent bleeding in patients with severe hemophilia A, doses of 20 to 40 UI of FVIII/kg of body weight should be administered at intervals of 2 to 3 days. In some cases, especially in young patients, it may be necessary to shorten the administration intervals or use higher doses.
Von Willebrand disease (VWD)
Generally, 1 UI of FVW:RCo/kg increases the circulating level of the same by approximately 2%. The levels of FVW:RCo > 0.6 UI/ml (60%) and FVIII:C > 0.4 UI/ml (40%) should be achieved.
Normally, 40 - 80 UI/kg of factor von Willebrand (FVW:RCo) and 20 - 40 UI/kg of FVIII:C are recommended to achieve hemostasis.
A higher initial dose of 80 UI/kg of factor von Willebrand may be needed, especially in patients with type 3 VWD, in which maintaining adequate levels may require higher doses than in other types of VWD.
A suitable dose should be re-administered every 12 - 24 hours. The dose and duration of treatment depend on the patient's clinical condition, the type and severity of the bleeding, and the levels of FVW:RCo and FVIII:C.
Pediatric population
The safety and efficacy of Fanhdi have not been established in children under 6 years of age for the authorized indications.
The dosage in children 6 years of age or older is not considered different from that of adults, as it is associated with body weight and adjusted to the clinical outcome of the conditions mentioned above.
